THE RELATIONS OF BIRDS TO MAN. The town of Durham, New Hampshire, in which this book has been written, may serve to illustrate in miniature the relations that exist between the world of birds and the world of man. This town abounds with homesteads distributed over its more habitable portions, with considerable areas of wood- land and rocky pastures, while on the east it adjoins that arm of the sea called Great Bay. Running into this bay is the Oyster River : below the dam whicli holds back the fresh water this is a tide-stream, overflowing salt marshes through part of its course. As a result of this unusual situation, Durham has an extraordinarily rich fauna and flora, making the region one to deliglit the heart of the naturalist. During the summer season birds are abundant in this town. In the yards about the houses the chipping-sparrows are cherished dwellers, building their horse-hair nests under the very windows, and supervising the lawns and roadways for grasshoppers, caterpillars, and many other insects found among the grasses and low herbage. The robins are also abundant, running over the lawns in search of earthworms, cutworms, and grasshoppers, often building their nests in the trees in the yard, though more conunonly rejjairing to the 1 BIRDS IN THEIR RELATIONS TO MAN. near-by orchard for that purpose. The bkiebirds feed more freely upon low-living insects than even the robins do, eating great numbers of cutworms and similar pests about the borders of the garden, as well as searching for insects in the fruit and shade trees. Far- ther afield this area next the ground is supervised by various other birds : in the pastures and grass-lands sparrows, meadow- larks, bobolinks, blackbirds, and quails are always searching for caterpillars and other insects ; along the borders of the forests che winks and brown thrashers scratch beneath the shrubbery for such insect fare as is there available ; in the deeper woods the ruffed grouse is similarly engaged, while along the margins of ponds and streams the sand-pipers, plovers, woodcock, and snipe are always probing for hidden tidbits. Fortunately, trees are abundant in Durham : near the houses and along the streets shade and ornamental trees abound ; in the orchards apple-trees prevail ; along the water- courses alders and other shrubby trees hold sway, while in the forests oak and maple and beech and stately pines are everywhere. All of these trees have their insect enemies : in tlie trunk are borers of the bark, the sai)-wood and the heart- wood ; on the branches are gnawing and sucking insects ; on the leaves are caterpillars and plant-lice and leaf-hoppers and liosts of others. Set over against these destroyers are many feathered enemies : the woodpeckers, assisted by the nut- FEMALE RED-WINGED BLACKBIKD. THE IIKLATIONS OF BIRDS TO MAX. i] hatches and creepers, look after the msects on and beneath tlie bark of both the trunk and branches ; the chickadees and warblers and vireos and kinglets are always scrutinizing tlic leaves for their inhabitants, and are assisted in the case of the caterpillars and larger insects by the bluebirds, thrushes, cherry-birds, and many others. The air is no less thoroughly supervised by our feathered allies than are the grasses and the trees. Most insects at one stage of their existence are aerial : by day the butterflies, the beetles, some of the moths, the grasshoppers, the hosts of two-winged flies, and many others are upon the wing: while by night an even greater host of moths, fire-flies and other beetles, bugs, and many other insects are abroad. To keep in check these hordes of flying things there are certain well- marked groups of birds : by day the swallows of many species and the chim- ney-swifts are constantly patrolling the larger spaces of the air, over both land and water, capturing mil- lions of these aerial insects ; the khigbird, jjewee, and other fly-catchers, as well as to a more limited de- gree the cedar-bird and bluebird, capture the in- sects that pass witliin their range of vision as they perch upon fence or stump or tree; the .warblers and nn: kingiuim.. vireos catch those insects flying in the iiiunediate vicinity of the green-leaved trees, while the redstarts have well been named the fly-catchers of the inner tree-tops ; by night the nighthawks and whip- 4 BIRDS IN THEIR RELATIONS TO MAN. poorwills are rushing everywhere through the air catching in their capacious maws insects of all sorts and sizes. With all these hirds to devour them, it is evident that the insects of the air are well provided against, if we will only en- courage our aerial friends as they deserve. But insects are not the only pests troublesome upon our farms. In and about the barns and out- l)iiil(lings mice and rats do much damage to grains, eggs, and poultry ; in the grass-fields moles and meadow-mice are some- limes injurious; in the or- chards rabbits often girdle young trees by gnawing I lie bark. Against these also the birds help us : the hawks and owls feed largely upon all these rodents, and per- form a great tliough little appreciated service in keeping them in check. After many years of study, in New Hampshire as well as many other States, of these relations of birds to agriculture, we are convinced that the birds are a most potent factor in making crop production possible, that without them Ave should be overrun with pests — vertebrate and invertebrate — to an extent of which we now have no conception. And so we are disposed to be lenient towards tlie few shortcomings of the birds which loom so large to many who see only one side of tlic pirlure. Frnil is pilfered by some of the birds, though ill our region so few clierries and small fruits are raised and llicj-c is relatively so much wild fruit that the loss is of small THE YELLUW ^VAKK1.1■: THE KELATIUXS UF BIRDS TO MAN. 5 account. In orchards near the woods a few trees are often disbudded in winter by ruffed grouse, and some other trees are treated in a similar way occasionally when the pine grosbeaks visit us. In corn-fields some corn is pulled up by crows, though our farmers prevent this largely by various means, and from us at least find no objection when they are able to shoot these wily thieves. And the same is true in the case of the yellow-bellied sap-sucker when it is girdling a tree, if only the owner will not extend his liatred to the woodpeckers that resemble it, — the downy and tlie hairy, — which are so eminently useful. In England some birds are HEAD OF HAWK. put on the black-list because they feed upon fish, but with us this is never thought of. We are sure the kingfisher is not begrudged his scaly diet by any one wlio is able to appre- ciate the fitness of the bird to our river scenery. And we can well spare the few fish our ospreys catch in the waters of the bay, when we are rewarded by the sight of the stately birds soaring through the air. About the only bird offence we are unable to condone is the robbing of our poultry-yards by the hawks and owls; and here, uiirortiiiiatcly, llic inoffen- sive species generally have to pay the })enalty lor the crimes of their more ferocious kindred. 6 BIRDS IN THEIR RELATIONS TO MAN. As to the relations between the birds themselves — especially the few that prey upon their kindred — in general we are con- tent to let Nature work out her balance of life in her own HEAD OF SHRIKE. way. The chief exception to this under our present condi- tions would be in the notable case where short-sighted man has interfered with Nature's balance by introducing the Eng- lish si)arrow, which, we regret to say, is becoming well estab- lished in our town. And we have the same feeling with regard to those parasitic and predaceous insects which birds undoubtedly devour : we are quite sure that by so doing they are helping to keep the balance of insect life where it will be most effective for man's benefit. The birds are also to be credited with the destruction of an enormous amount of weed-seed, a service which is little appreciated by the general public. The estimate by Profes- sor F. E. L. Beal, that the tree-sparrows alone will eat eight hundred and seventy-five tons of weed-seed in Iowa in one season, should help to a more general appreciation of this phase of bird activity. There are various other benefits derived from birds which are not illustrated in our local conditions. One such is the THE FIELATIONS OF BIRDS TO MAN. 7 supplying us with down by the eider-ducks ; anotiier, the scavenger value of buzzards and vultures in our Southern States, as well as of gulls in the harbors of our cities; and yet another, the indication of shoals of fisli by the presence of gulls, as along our Atlantic coast. Next in importance to the direct economic value of this bird Ufe to our towns-people should be considered its value as an object of study and interesting recreation. Many people find in the birds a subject of constant interest in which they are kept out-of-doors in the health-giving atmosphere of our coastal region, finding always something to occupy and tran- quillize the mind. With the modern devices for such study, — the splendid field-glasses, the improved long-distance cam- eras, the tents for close-range observations, — together with the constantly increasing number who are being attracted to it through the schools and the fascinating bird-books of later years, the class of people who thus find in the observation of bird-life a delightful pastime is certain to increase rapidly. And there are many people with no special liking for natural history studies who yet appreciate the value of birds in ministering to man's love of beauty. To these the sight of a brilliant hunmiing-bird poised before a flower, of a yellow warbler among the apple-blossoms, or of a splendid heron beside the rippling waters is a memory to be cherished certainly as much as the sight of a great masterpiece of paint- ing or sculpture created by Imman genius. There is also another relation the birds of Durham l)rar to its human inhabitants. In the woods everywhere rnH'iMl grouse are plentiful; in the low swales woodcock, and in the wet meadows Wilson's snipe are not uncommon ; along the bay shores and by the marshes plover of various sorts are often found: on the waters of tlie bay wild ducks and wild geese are abundant during the fall migration. All of these birds afford those inliabitants who enjoy Icgiliinatc spni-j an opportunity for invigorating days of Innilin-, as well as a < cr- 8 BIRDS IN THEIR RELATIONS TO MAN. tain amount of excellent food. This game might also easily become a source of revenue to many other people in the town by attracting city visitors for the shooting season. In the following pages we have attempted to discuss in a broad yet specific way the relations of birds to man as illus- trated in temperate North America. The book has been made possible only through the labors of such investigators as Forbes, Merriam, Beat, Barrows, Fisher, Palmer, Judd, Warren, Herrick, Montgomery, and many others, upon whose published results we have freely drawn. The need of the book was first shown when the senior author undertook to teach a college class the subject of economic ornithology, and its first draft consisted of the lectures prepared for that class. When later the junior author — a life-long student of birds — became associated with liim, a joint study of the Avhole sub- ject was undertaken, the results of which are here presented. A considerable proportion of the illustrations in this book are from original photographs — chiefly of mounted specimens — by the authors. The others have been gleaned from vari- ous sources, which are credited beneath the pictures. HEAD OF CHIPPING-.si'ARKOW. riioUjiliaplttd J'roia lij'f bij Dr. /.'. II'.

Wherever birds roost in numbers, pellets or excreta or botli may be gathered, and when analyzed will give results scarcely less valuable than those obtained by dissection, with the advantage that there is no sacrifice of bird life. A study of the food of nestlings is less diriicult and ou tlic whole more satisfactory. Both the kind and llic (piaiitily i:i;ai)Y tu fekd. may be accurately determined without injuring so much as a feather.

It usually ]iapi)ens, however, that the nest is not in a i)osilion 14 BIRDS IN THEIR RELATIONS TO MAN. where a tent can be placed beside it. In that case locate the tent in a good place as near by as may be, and then cut oil the branch, fasten it strongly to a support by cords or screws, and by degrees move it to a place beside the tent. When it is not necessary to remove the nest, the tent may be pitched as early as the day of hatching, in most cases at least, without fear of causing the old birds to desert. But Avhen I lie nest has to be moved, unless the degrees of progress are jiiadc very short, there is danger of desertion if the moving is undertaken beforr' the young are well covered with starting pinfeathers.

At that time also parental devotion is at its full strenglli, and the old ])irds are willing to face dangers tliat they would not otherwise encounter.' Where a nest is to be moved and there is not much danger of being bothered by prowling boys, we usually employ a fairly good-sized tent, as it gives the observer a chance to change his posifion without giving external evidence of it.

Sometimes several nests are brougld one after aiiollicr to I lie same site. In the illustration opposite there is a cliippinf,'- sparrow's nest in position and a robin's in waiting only ten feet away. Except for the trouble and a very slight delay in the work of the l)irds, there is no ol)jecli(ni to striking tlic tent every evening and pitching it again in the moriung. At such short range there is generally no doubt as to the identity of every object that is brought to the nest. Some birds bring food in their gullets 'and feed by regurgitation. If it is not possible to see what they are delivering, wait till the old one has gone aw^ay, then go out and examine the young. Four times out of five you can tell what they have swallo\v<'d by looking through the transparent skin of their necks. In case there is still a doubt, it is not difficult to make them dis- gorge by placing a thumb and finger below the mass and working it upward to tlie mouth. Simple honesty demands that it be returned when you are done with it. See how many hours a day the old birds attend their young and how many times they average to feed })er hour. Estimate the proportion of each kind of food from an examination of your notes. Then by weighing samples of the different kinds you can quickly compute the daily consumption. As a check on the above method weigh tlic yoimg at the same hour every day. Collect several excreta and tind the average weight, also observe the average number voided per hour. The weight of excrement for the day i)lus the bird's gain in weight for the day will give the weight of food con- sumed, less the small amount lost by respiration. The excreta of young birds is so well wrapped in a ( oat of albumen that it is not so ohjeclionable to handle as might i)e supposed. It may be obtaine(l at any time by taking the bird from the nest and keeping it out foi- a lew minutes. In order to distinguish one nestling from another they may 1(^ BIRDS IX THEIR RELATIONS TO MAN. b(^ marked either on llie leg or on the side of the bill with a nitrate of silver pencil, which may be pnrcliased at any drug store. There may be some difficulty in applyhig the pencil so as to make a good mark, owing to the oily skin of the birds, but see that it is wet and keep rubbing. The marks will need to be renewed occasionally. The great value of this method is that it enables one to get photographs of the birds as they are being fed, beautiful examples of which are shown in Professor Herrick's book. There are, however, elements of danger to the birds, which should by no means be overlooked. There is danger of desertion by the parents, of too much exposure to the hot rays of the sun, of lack of protection from the cold of night or of the storm and stress of w^eather, as well as of various living enemies. No one should remove a nest from its original site who is not willing to take every ])ossible jirecaution to avoid a tragedy. HEAD OF BROTTN THRASHER. CHAPTER TI. THE DEVELOPMENT OE ECnXOMH" OHXTTIK )L( MIV. When Coliinibiis was niakiiiij;' tliat cvciilliil voyage which led to the discovery of the New World, lie was chec^red by the sight of small birds that appeared beside his ship, telling him of his approach to land. And ever since then these children of the air have been of interest to the white people who have come to America, as they had been for untold ages before to the red men who roamed over the continent. The early New England settlers were troubled by some birds against which they declared war, and cheered by others to which tliey extended the offerings of friendship. And even in those early days there were some men who found in the study of birds a source of delight to which they gladly gave their time. It is nearly two centuries since Mark Catesby wandered through the wilds of Florida and Carolina, seeking out the birds and other animals of those unexplored regions, the publication of his results having been begun in 1731. Towards the end of the eighteenth century there were many workers in the field, the most prominent being Bartram, Latham, and Barton. And before the end of that century Alexander Wilson came over from Scotland to begin those pedler journeys during which he became interested in Ameri- can birds. At the opening of the nineteenth century Wilson was greatly interested in our bird life, and as early as 18()-jay were made by Professor F. E. L. Beal. "The destruction of birds of prey in Pennsylvania, fol- lowing the passage of the 'scalp act' of 1885, had attracted wide-spread interest, and showed the necessity for correcting erroneous views concerning tlie value of hawks and owls. About tw^o thousand seven hundred stomachs of these birds were collected, the contents carefully examined, and the re- THE 15AKN-<)\V1, AND lis I'KKV. {A/'rr I'liitcd States Division of Biological Surrey.) THE DEVELOPMENT OF ECONOMIC ORNITHOLOGY. 23 suits published iu 1893 in a bulletin entitled ' Hawks and Owls of the United States,' illustrated by twenty-six colored plates. Of the seventy-five species and subspecies which occur in America north of Mexico, only six were fonnd to be injurious, while several were shown t(j be beiieficial. About the tune the work was begun bounties on birds of prey were, or liad recently been, offered by Colorado, Indiana, ]^ew Hampshire, Ohio, Pennsylvania, Virginia, and West Virginia. At pn^sent not only have all the important State bounties been withdrawn (the ads still in force are mainly local), but several States have adopted protective measures. New Hampshire and Ohio began with eagles, Rhode Island with fish-hawks, and New York and Minnesota with owls. Pennsylvania and Alabama now protect all except the six or seven really injurious species, while daring the present year Utah has gone so far as to make it unlawful to kill any hawks or owls. Such changes show the gradual appreciation of the value of these really useful birds. " In the case of the crow nearly one thousand stomachs were examined, and the charges of pulling up sprouting corn, of injuring corn in the milk, of destroying fruit, and of destroy- ing eggs of poultry and wild birds were all sustained. But it was found that corn in the milk formed only three per cent, of the total food, and most of the corn destroyed was waste grain ; that the destruction of fruit and eggs was trivial, while, on the other hand, many noxious insects and mice were eaten. The verdict was therefore rendered in favor of the crow, since, on the whole, the bird seemed to do more good than harm. '•Similar studies of crow blackbirds (based on about two thousand three hundred stomachs) and woodpeckers (in- cluding nearly seven liuiKlrcil stouiachs), published in 1895, showed that these birds were decidedly benelicial.

The publications on birds already issued include seven special bulletins, fifteen papers in the Annual Reports for 1886-1893, inclusive, and eight papers in the Yearbooks for 1894-1898. Some of these papers, such as ' Seed-planting by Birds,' ' Hawks and Owls from the Stand-point of the Farmer,' 'Birds that injure Grain,' and 'Birds as Weed Destroyers,' deal with general topics of special interest. The investiga- tions on some thirty grain- and insect-eating birds were sum- marized in 1897 for a bulletin entitled 'Common Birds in their Relation to Agriculture,' and the work of the Division has also formed the basis of two important sunnuaries, one by Miss Florence A. Merriam, entitled ' How Birds affect the Farm and Garden,' the other by Professor Beal, on ' Eco- nomic Relations of Birds and their Food.' "The educational work of the Biological Survey has not been confined to laboratory studies or publications. The Division has prepared exhibits to illustrate the food habits of birds and modern methods of investigation for the expositions at Cincinnati in 1888, Chicago in 1893, Atlanta in 1895, and Nashville in 1897. It endorsed the proposition to establish a 'Bird-day' in the schools in 1894, and issued a circular on the subject two years later. Ever since its organization it has acted as a bureau of information on all subjects relating to birds or their distribution and habits. In short, it has spared no effort to advance the cause of economic ornithology in every possible way." Such a record as this is certainly one in which any com- pany of workers may well take i)ride. And when we realize how few the workers have been and how great has been the territory they have covered, we can but feel that remarkable results have been accomplished. As to the future jjrogress of economic ornithology it is becoming more and luore evident to careful students of the subjccl thai nmcli of the best work hercaller must be inten- 26 BIRDS IN THEIR RELATIONS TO MAN. sive rather than extensive. In the preliminary stages of our knowledge the miscellaneous collection of bird stomachs from all parts of the country at all seasons of the year is a neces- sary and useful step. The results thus obtahied in regard to many species are of great value, but in the case of others, notably those of doubtful utility to man, — as, e.g.^ the fly- catchers mentioned above by Dr. Palmer, — they must be supplemented by careful studies on the intensive plan. An excellent example of this is Dr. S. D. Judd's notable study of the food preferences of the cat-bird,^ and other studios of the same sort are being made by Dr. Judd and other members of the Biological Survey on a farm near Washington controlled by the Survey.- It Avas long ago pointed out by Forbes that many of the most important problems in economic ornithology rested at bottom upon the science of entomology. And in the diffi- cult and perplexing problems that arise in the case of many species a fuller development of entomological knowledge is greatly needed. One of the most important of these topics is that of the relation of parasitic insects to each other and to their hosts. The discussion in this chapter has been purposely re- stricted to the development of our knowledge of the more general economic relations of birds. For a history of the various special phases of the subject — game, eggs, feathers, guano, introduction of foreign birds — the reader is referred to Dr. Palmer's article in the Yearbook of the Department of Agriculture for 1899. 1 American Naturalist, vol. xwi. pp. 892-397. ^ See "Birds of a Maryland Farm."

A COMPREHENSIVE survey of tlie feeding habits of birds leads to the conclusion that the connnon terms A^egetivorons and insectivorous have but a relative significance. Tliey imply predominance in a given diet rather than an exclusive restriction to it. We cannot indicate a single finch, grouse, or pigeon — the most exclusive of the vegetarians — and say that it never eats insects, while on the other hand, after being assured that swallows and flycatchers — the most persistent of the insect hunters — sometimes eat berries, we cannot feel jus- tified in maintaining upon purely negative evidence that any of the so-called insectivorous birds never eats vegetable food. The vegetation -eaten by birds may conveniently be con- sidered under three heads, — namely, fruits, foliage, and roots. Under the first would be included all seeds and seed-bearing products of plants ; they may be subdivided into seeds and achenes, nuts, and fleshy fruits. Under the second head would be comprised leaves, buds, and blossoms ; while the third would include roots and root products. The largest proportion of the seeds eaten by birds are pro- duced by herbs, most of which are useless, while many of them are noxious weeds. The quantity of pestiferous seeds thus annually destroyed is enormous, and man is deeply indebted to the birds that destroy them. The great group of many- flowered plants — the order Composihv — sui^plies food for a multitude of small finches. Early in the season the downy heads of the dandelion call sparrows and goldfinches to lawns and road-sides. A little later horse-weeds and thistles furnish sinular food to the same hungry company. The ragweed, which springs up unbidden everywhere, is perhaps 27 28 BIRDS IN THEIR. RELATIONS TO MAX. the best bird provider in this family ; in grain-fields, along road-sides, and in worn-out pastures this plant affords the birds a feast unsurpassed either in amount or duration. During the latter part of their stay the summer sparrows largely depend upon it ; while in the winter bob-whites, gold- finches, redpolls, English sparrows, snow-flakes, and horned larks make festival among its miniature branches. Even the red-headed and red-bellied woodpeckers as well as the flicker have been known to partake of these ragweed seeds. The buckwheat family — the order Polygonacew — also fur- nishes a liberal supply of food to many birds. The list of birds that devour these triangular seeds is a long one. Knot- weed, sheep-sorrel, dock, bindweed, and many more — each contributes to the birds that frequent its station. Juncos, chipping-sparrows, and redpolls come to the door-yard to glean among the knotweed ; cow-birds, redwings, mourning- doves, bob-whites, and flickers look for the seeds of dock and bindweed in fields and meadows ; mallards, teals, and other river ducks dabble for the seeds of water-smartweed and other aquatic or semi-aquatic varieties, making a full meal of them whenever they are able to do so. The seeds of the pigweeds, hemp, nmllein, and a host of other weeds belonging to less numerous families are also freely drawn upon for the support of bird life. The wild grasses of the order (inuiuncw also supply their share. Among them the pigeon and other grasses of the genus Setarla are perhaps the most important in bird economy, as they invade cultivated ground everywhere and are fed upon very generally by sparrows and many other birds. In swamps and along the borders of ponds and streams, es- pecially in tlie Southern and Western States, wild rice grows abundantly, and during the autumnal migration it is often the predominating element in the diet of such marsh-loving birds as bobolinks, blackbirds, rails, and ducks, all of which be- come very fat upon it. THE VEliETABLE FOOD OF 13I1{DS. 29 Cultivated grains are consumed in varying quantities by a large number of birds, thougli comparatively few commit appreciable depredations, the grain eaten being generally gleaned after harvest. All varieties of small grain, such as wheat, rye, oats, and related kinds, are taken without apparent discrimination. The birds that liabitually feed upon them are those already named as eaters of the larger seeds, — crows, jays, blackbirds, pigeons, prairie-chickens, and other members of the grouse family, sparrows, meadow-larks, horned larks, brown thrashers, towhees, and others. The crows, blue-jays, blackbirds, and English si)arrows do con- siderable harm at times, though it is probable that the insects destroyed at other times by all except the English sparrow go far to compensate the loss. Pigeons and grouse are not sufficiently abundant to do much damage. In the West wild ducks and geese visit the grain-fields and sometimes cause considerable injury by taking the sprouting seed from the newly sown fields. During the fall migration the southern rice-fields attract many birds. Foremost among these are the bobolinks, or rice-birds as they are called in the South, and blackbirds, both of which at this time are content to live by rice alone. They assemble in countless flocks and commit serious depredations against the rice-planters. Ducks and other water-birds also resort to the rice plantations for a share of the plunder, but what these get is generally compensated for in the feathers and flesh that the ow^ners obtain. Indian corn, or maize, on account of its larger kernels is precluded from the food list of most of the sparrows, but otherwise it has the same de})redators as the smaller grains. Among the casual devourers of maize are the woodpeckers and nuthatches, which seem to prefer it to all other cereals. Cultivated grasses and clover seeds are frequently taken by sparrows. Sunflower seeds are sought by the more arboreal finches, like the purple finch, goldfinch, and the cross-bills. In the garden we find that lettuce, turnip, and similar seeds 30 BIRDS IN THEIR RELATIOiNS TO MAN„ are enjoyed by goldfinches, and that Enghsh sparrows and Baltimore orioles occasionally fall into the evil habit of eating green peas. Except in rare instances, however, these garden invasions are insignificant. Among the trees that contribute seeds to the birds, the dif- ferent species of elms deserve notice, the more especially as their seeds mature earlier than those of most other plants. The seeds of the widely diffused white elm ripen in the lati- tude of central New England about the first of June, and at once become a lure to the arboreal seed-eaters, — cross-bills, goldfinches, and purple finches, — which when the seeds fall follow them to join the host of "ground sparrows,'' song, vesper, and others, that ordinarily live on the seeds of weeds and do not feel at ease away from the cover of low vegetation. The birches are also iiii[)()rfaiil elements in bird food, because their tiny winged seeds ai'e cpiite persistent, many of them cling- ing to the catkins throughout the winter. They ofi'er an un- faihng supply so long as they remain upon the trees, and are liberally patronized by the winter finches, redpolls, siskins, and cross-bills. The small gray birch is levied upon in autumn by chipping and field sparrows, and in winter it becomes an es- pecial favorite with jnncos, tree-sjiarrows, and redpolls. Seeds of the yellow birch are sought by redpolls, siskins, and cross- bills, the last two more particularly as they prefer the woods, where this species is usually found, to more open pastures. The seeds of the other birches are also eaten to some extent, but they do not appear to be held in such high regard by birds as the two kinds that have been mentioned. Maple seeds are more or less important in bird economy according to circumstances. As a rule, the sparrows and finches do not care for them so much as for smaller seeds that are more easily swallowed. The winter grosbeaks, pine and evening, however, find them quite to their taste, and give them almost exclusive attention so long as the supply holds out. It sometimes happrns tliat a severe drouth in August THE VrjJRTABLE FOOD OF BIKDS. 31 dries I ho stems of maple seeds belore they liavc become woody, so that they are tougli enough to witlistand the blasts of autumn, and thus remain upon the trees indefinitely. Under these conditions the grosbeaks find life easy and never fjuit the neighborhood of trees thus laden imtil the last seed is plucked. If tlie ground is not covered with snow, they frec{uently obtain maple seeds after these are fallen. Among the other deciduous trees bearing dry fruits eaten by birds are the poplars, sycamores, and ash-trees. None of them are in general favor, however, the larger finches and grosbeaks being their only patrons. The cone-bearing trees cater to a rather select company of birds. This is particularly true of the white pine, the vaned seeds of which are so deeply hidden between the scales of its great cones that they cannot be extracted by ordinary bird tools. There are a few specialists, however, endowed with an appe- tite for sucli seeds and an adequate apjjaratus for obtaining them. These are the cross-bills, whose falcate mandibles are admirably adapted for grasping the vane of a pine seed and thus withdrawing it from its hiding-place. The siskin is another lover of pine seeds, and it is able to supply its wants by having a bill which for a finch is very long and acut(\ Although most of the white-i)ine seeds fall in Sep- tember, enough remain in place to keep the birds supplied until early winter. Besides these specialists, several other birds occasionally eat pine seeds.

Hemlock cones are so much smaller than those of the white pine that the seeds are more accessible, and conse- quently have a somewhat larger following. The siskins and the cross-bills are very fond of them, and wherever they find a fruitful growth they are likely to remain till the store is spent, — usually about midwinter. After the snow has come, covering the weeds, goldfinches also resort to the hemlocks. Even the chickadees, nuthatches, and woodjjeckers seem to find it agreeable to sandAvich these seeds in with their fare of frozen insects. The spruces have larger and more refractory cones than the hemlock, and rank about with the white pine in bird economy. The other coniferous trees are of varying impor- tance in this connection, but an account of them would not differ materially from that for those already mentioned. Comparatively few of the vegetivorous birds are capable of devouring nuts. Crows and blue-jays, by holding them between their toes and their perch, are able with their strong bills to remove the shells from any of the thin-shelled nuts, and during the mast season feed largely upon them. The wild doves, pigeons, grouse, turkeys, and many of the ducks eat them entire, leaving the task of shelling to their muscular gizzards. To all these birds nuts are a standard article of diet. To the nuthatches and woodpeckers they are among the contingencies, as a rule, though some of the western woodpeckers seem to dc^pend ui)on them considerably for winter food. The smaller nuts, or nutlets, approaching the borderland of the seed-like achenes, such as those of the hornbeams and bass wood, are eaten to some extent by the grosbeaks and woodpeckers.

They are especiaUy used by the old birds for feeding the nestUngs. The famihes of silk-spinning moths and their allies — for- merly included under the Bombycidae, but now subdivided into many groups — include a number of the most injurious insects affecting fruit and shade trees. The larvae of this group are hairy caterpillars which feed upon leaves, and when fidl grown spin silken cocoons for protection in the pupa state. The tent cater})illar of the apple and wild clierry, the fall web- worm, the tussock-caterpillar, and many similar insects be- long here. One of the most 1 1 ( (tably destructive members ol' the group is the gypsy moth, recently so prominent heforellie jjnblic in Massachu- setts. The two sexes of the adult moth in this species dif- fer greatly : the general color of the male is brownish and of the female whitish. The eggs are laid in bunches in a great variety of situations, and the resulting larvie feed upon the foliage of nearly every kind of tree and shrub. Com})aratively few birds attack the hairy caterpillars of this group, but some — as the cuckoos and blue-jays — devour them eagerly. The European cuckoo is said to regurgitate the mass of sivins thus swallowed ; probably our species have a similar habit. The I;n'<'er bombycid caterpillars — like those of the cecropia and polyphenujs moths — are eaten by some of the hawks.

The order of two-winged ilies — Diptera — contains com- ])aratively few families of injurious insects. The species most 52 BIRDS IN THEIR RELATIONS TO MAN. destructive to cultivated crops appears to be the little Hessian fly (^Cecidomyia def(friicfor)^ often so serious an enemy to wlieat. The adult is a small gnat-like creature whose eggs are de- posited on the blades of growing wheat, the resulting larvse absorbing tlie sap of the plant and dwarfing or destroying it. Closely related species attack the heads of clover and of wheat. There is no doubt that great numbers of these flies are devoured by swallows, swifts, and nighthawks during the aerial evolutions of these birds. The long-legged crane-flies of tlie family Tipulidae are often found in birds' stomachs. The adults of these insects appear in spring, often in great munbers, and deposit their eggs in grass-lands. A short time later the eggs hatch into small, blackish, footless grubs, that feed upon grass-roots and decay- ing vegetable matter. AVhen full grown they are about an inch long and of a grayisli-black color. They now change to pupje, to emerge as adult ilics a fortnight later. The larvje sometimes do serious injury to meadows. The Coleoptera, or sheath-winged insects, form the immense order which includes the beetles. The front wings are hard- ened into horny cases Avhich cover and protect the membranous second pair, the mouth parts are formed for biting, and the transformations are complete. In the larval state the beetles are connnonly called grubs. A typical example of a beetle is illustrated on the opposite page. Many beetles are destructive to vegetation, a few live on decaying organic matter, and some prey upon other insects. The tiger-beetles form a distinct family (Cicindelidce)^ the members of which devour many other insects, being pre- daceous in both the larval and adult states. These beetles arc often brightly colored and niarked with distinct spots. They are abundant in sandy situations and may be seen commonly along lanes and roads or by the sides of streams. Many of them are eaten by certain kinds of birds. The ground-beetles of the family Carabidcc Ibi'ni an im- TIM'.

The larvae of this group vary mucli in appearance and life-history : some live exposed on leaves, others are leaf-miners, and others live on roots and under ground. Most of the larv;e are protected in some way from the attacks of birds, which apparently devour many more of the adult bee- I les than of the larviie. The common May-beetle, or "June- bug," belongs to a family — Scarahceidce — which contains many other well- known depredators. This insect is developed from the white grub, or "grub-worm," so often found in pasture and meadow land. The rose-beetle, or "rose-bug," is one of the others: the adult is a hard, lirown insect that feeds upon the foliage, flowers, or fruit of a great variety of plants. Its eggs are deposited in light sandy soil and the larvae feed upon roots. When fully grown they change to pupa? and later emerge as adult beetles. Grubs like these are eagerly devoured by robins, blackbirds, crows, and others ; these natural enemies aid greatly in checking the ravages of such pests. A large number of injurious insects are found among the snout-beetles of the family ( 'i(rcii/io)i}(J(c and certain related families groujx'd togetliei' in a suborder <'alled l{liyncoi)hora. The plum and apple curculios, the bean and pea weevils, the various grain weevils, the corn "bill-bug," the white-pine borer, and many other pests belong here. The larvae of these insects are usually footless grulis and feed upon a variety of materials. The adult beetles have a habit when disturbed of droj)ping lo the ground, drawing tlie legs against the body, THE AMMAL FOOD OF BIRDS. 55 and remaining- quiet for some time. Many of them resemble particles of rubbish of such various sorts as commonly occur at the soil surface.

The salient fealures in the lile-liislorv (»(' ilic family may be gathered fnmi that of tlie jjliiiii-cnrciilio. Tlie adult beetles deposit eggs in the young plums and the result- ing grubs feed upon the pulp of the fruit. They become fidl grown in a few weeks, the plums fall to the ground, and the grubs enter it to pupate, emerging later as beetles. The ants, bees, wasps, sawflies, and various four-winged parasites form the order Hymenoptera. The j"aws of these insects are fitted for biting and the remaining mouth parts for sucking. The transformations are complete, and tlie adults, with few exceptions, have two pairs of membranous wings with few veins. This order includes some highly bene- ficial as well as some extremely injurious s^jecies. Few families of insects enter more largely into the food of birds than that of the ants {Fonnicidce). Being abundant in all sorts of situations, it is not strange that woodpeckers, cat-birds, and various other species of birds have learned to rely upon them for much of their food. Some people class ants among the beneticial insects, but, while they are doubt- less useful in certain ways, it seems to us that there can be no question that birds which eat them should receive credit rather than blame for so doing. The ants are so abundant and multiply so rapidly that were there no check upon their increase they would be likely to become very troublesome, as indeed they now are in many localities. Probably the most important groui) of parasitic insects is that comprising the ichneumon-flies of the families Jimcoiiithf and Ichneumonkhv of modern entomologists. These little creatures vary greatly in life-habits, but a largv proportion of them arc pi-iinar\ pai'asilcs of injin'ious insecls. 'flic 56 BIRDS L\ THEIR RELATIONS TO MAN. SI'HINX J.AKVA WITH COCUCJNS OF J'ARA.SITK ADULT PAKASITK AT RIGHT, Natural size ami inu,i:;nifie(l. (After Piley.) adults are four-winged flies with slender bodies and long antennae, and the larvae are soft, fleshy grubs. In many species the females have long egg-depositors, by which they can reach caterpillars hid- den in trunks of trees or stems of herbaceous plants. The eggs are usually de- posited either on or in llir body of the larva selected as the Aictim : they soon hatch into grubs that de- velop at the expense of the (issues of llir liosl. Some of the ichneumon-fly larv.-B are internal parasilcs, living beneath the caterpillar's skin, while others aHacli tlieiiiselves externally. In either case the host insect is doomed: it may be killed long before it gets its full larval growtli, or it may be allowed to complete that growth and spin a cocoon, but sooner or later the parasites — like the fox in the fal3le — will gnaw away its vitals. When the ichneu- mon larvie become fully grown, they generally spin slight silken cocoons, within which lliey change to pupae, to emerge later as adult Hies. There is a group of ichneumon-flies, commoidy called Microgasl ers, wliidi spin their cocoons on the back and sides of the lar\;e of butterllics and inoths, giving the host a most singular appearance. A specimen of a connnon sphinx larva bearing these cocoons is represented above. Ichneumon-flies are eaten to a considerable extent by many birds, especially the llycatcliers. The tact that a bird may eat a certain lunnber of insects of this sort without necessa- rily doing any injury to agriculture is indicated in the discussion of the relations of vegetivorous and carnivorous insects in ('hapter VI. Besides the insects proper there are many animals that are eaten by birds. The spiders are the hiost important of these. THE ANIMAL FOOD OF BIRDS. 57 Spiders have eight legs, with a body divided into two principal parts, and are predaceous creatures Avhirh feed largely upon insects. They are found i:i all sorts of places and dnring all seasons of the year. They enter very largely into the dietary of the smaller birds, being especially fed to the nestlings, and their surprising rate of reproduction seems to have been de- veloped, in part at least, to meet this constant drain upon their numbers. The harvest-spiders, harvest-men, daddy-long-legs, or grab- for-gray-bears, as they are variously known in dillerent parts of A HAKVKST-SI'IDER. the United States, form a distinctive family, — J^Jmhox/iUUr, — distinguished by having the fhree divisions of the body — iicad, thorax, and abdomen — closely united, and four pairs of very long legs. A connnon species is pictured above. These 58 BIRDS IN THEIR RELATIONS TO MAN. harvest-spiders are predaceous creatures, feeding especially on the aphides, or plant-lice, as well as upon dead insects. Most of them move about at dusk, rather than during- the day. Not- withstanding the disagreeable odor given off by them when handled, they are occasionally found in birds' stomachs. The common "thousand-legged worms*' form a subclass of animals known to naturalists as Myriapoda, — the many- footed. They abound under logs and rubbish or amid the fallen leaves of the forest, where they are often picked up by robins or other thruslies. Some Myriapods, of which the connnon lulus is an example, feed upon vegetable matter, and are occasionally destructive to strawberries by eating the pulp of the fruit. Others are predaceous ; but very little is known precisely concerning the food habits of these ; conse- quently their economic status is ill defined. From their gen- eral habits we are led to think that their value may easily be over-estimated and that we need not regret their occasional destruction by birds. In addition to insects and their allies, birds feed upon many higher animals. Fishes are taken habitually by kingfishers, ospreys, the wading birds, and some of the owls. Frogs, lizards, and snakes are eagerly devoured l)y hawks, owls, and other raptorial birds, as Avell as by some of the waders and various other species. The mice, moles, shrews, gophers, ground-squirrels, and other small rodents also form a large part of the food of the birds of prey as well as of many other species, while the smaller birds themselves furnish consider- able subsistence for their larger relatives. CHAPTER V. THE AMOUNT OF FOOD CONSUMED BY BIRDS. Birds as a class are the most active members of the ani- mal kingdom. They have rapid circulation and respiration ; are constantly on the alert during all seasons of the year; travel long distances in migrating or searching for food ; rear large families, often two or more broods in a summer ; and, in short, perform for their size a prodigious amount of work. Because of this, one would expect them to require a large amount of food to keep up the energy they are so constantly expending, and the studies that have so far been made show that such is emphatically the case. Unfortunately, the problem of ascertaining just how much food wild birds need presents many difficulties in the way of its solution. So long as birds are at liberty, evidence must always be fragmentary and often uncertain. When they are kept in captivity, natural conditions are upset : the worry of confinement, the lack of exercise, and a changed diet are fac- tors of more or less importance ; we can scarcely say how much. With nestlings the matter is simpler, though much time and patience and common sense are necessary in order to obtain creditable results. Thus, it is not to be wondered at that in the wliole mass of ornithological literature — which latterly has increased to very respectable proportions — tliere is a striking paucity in this line. It is to be hoped that the gap will not be allowed to exist very much longer, as reliable data on the amount of food consumed is in economic importance second only to the kind consumed. Although information is scarce, yet there is enough to demonstrate that the quantity of food eaten by birds is relatively much greater than that consumed by any other class of vertebrates. 59 60 BIRDS J.\ THEIK RELATIONS TO MAN. Sixteen canaries mentioned by Dr. Stanley ^ ate one hun- dred grains of food per day, about one-sixth of their own weight. '^ A gull kept and fed in a garden devoured in one day fourteen mice and two rats. Another was seen to swal- loAv an entire rat, an operation, however, not accomplished without some difficulty, the bird making several efforts before it succeeded, and even then the tail remained visible for sev- eral minutes." ^ In The Ameincan Katuralist for July, 1899, Dr. Thomas H. Montgomery, Jr., gave some valuable data concerning the food of owls, based on a study of food pellets regurgitated at roosts. In the winter of 1898-99 four long-eared owls took residence in an arbor-vitae tree on Dr. Montgomery's grounds at West Chester, Pennsylvania, and from December 25 till February 22 were under his observation. Pellets were gathered weekly and analyzed. In the fifty-nine days the pellets from beneath this one tree yielded remains of two birds, one shrew (Bkt- rina), one common mouse (J/^/.s), and three hundred and forty-five field-mice [Microtus). Under a Norway spruce near by, where a short-eared owl roosted regularly and one of the long-eared occasionally, were found between February 26 and Marcli 26, twenty-eight days, evidence of one crawfish, five birds, two shrews, one jumping mouse (Zapns), and one hundred and five field-mice. Pellets believed to have come from tlie same owls, found under trees within a radius of an eighth of a mile, contained remains of five birds {Begulus, Junco, Ccrthia), seven shrews, and one hundred and forty- eight mice. Taken altogether here was an equivalent of one owl for two hundred and forty-six days, to which are credited twelve small birds, ten shrews, and six hundred mice, or about two and one-third animals, mainly mice, per day. For twenty-two consecutive days, December 25 to January 15, Dr. Montgomery counted four owls in the arbor-vitae tree 1 History of Birds, p. 225. '' Id., p. 143. THE AMOUNT OF FOOD CONSUMED BY BIRDS. 61 every day. The pellets taken from beneath the tree during that time showed parts of one finch, one shrew, and one hun- dred and ninety-nine mice. Dividing 201, the number slain, by 88, the number of days in which one owl would consume the same amount, we have 2.28, — what he would have eaten -in one day. As it is probable tliat more or less pellets were dropped elsewhere, we may readily believe that the average daily consumption deduced from the whole number of pellets is within the lines of truth. An adult crow that had been slightly wounded in the wing was once brought in and kept alive by us awhile for a food experiment. He was put into a small box, twelve by thirteen by twenty inches, and kept supplied with water, cracked corn, and oats. In addition, from twenty to sixty angle-worms were given him each day for five days. By that time he w^as fairly tame and ate freely wdiile being watched. We secured a quantity of small fish (Funchdus:), which were abundant in the brackish creeks, and offered liim some on the fifth day. He ate thirty grammes of them that day in addition to grain and the usual supply of earthworms. On tlie sixth day his animal food comprised sixty-eight angle-worms, ten shrimps, and eighty-five grammes of fish. By this time his wing was nearly healed, he was feeding well and showed a relish for fish, and, as we could procure them in unlimited numbers, we decided that the conditions were riglit for the final test. On the morning of the seventh day every eatable was re- moved from his cage, and a basin of water containing a num- ber of the living fish put in. As fast as the fish were taken out others were supplied. For three days he ate nothing else. During that time he consumed fourteen and a half ounces (av()irdui)ois), — making his daily consumption 4.83 ounces, more than a (paarter of his own wclghl. II would take over four hundred grasshoppers at maturity to weigh as much as did his daily ration of fisli. As there is no reason to suppose that uncaged birds would eat less than this cap- 62 BIRDS IN THEIR RELATIONS TO MAN. live, a little multiplying will show that a crow devours an astonishing amount of food in a year. A ruffed grouse killed in winter had in its crop twelve leaves of sheep-laurel and four hundred and thirty-five buds and bits of branches from apple and maple trees. Some of the twigs were half an inch long. That was the morning meal. It would have been duplicated at twilight. The crop from another bird of the same species contained over five hundred buds and twigs. From these examples it appears that the daily requirement of this grouse lies betw^een eight hundred and one thousand buds. At other seasons of the year it is impossible from an examination of its crop contents to judge with any certainty how much a grouse eats, as then the birds eat at all times of day. Professor Herrick,^ in his study of the red-winged black- bird, noted that three nestlings received food forty times in four hours on one day, and forty-three times in three and a half hours on another day. Four young kingbirds ^ were fed ninety-one times in four hours. Two young red-eyed vireos^ took grasshoppers, katydids, green larva?, beetles, and bugs of many kinds, also a few berries, once in fifteen minutes during two days and once in nine minutes on the third day. Four young cat-birds ^ received food forty-six times in four hours, after the old birds had become reconciled to the presence of the observer. Five times in succession large dragon-flies [jEschna heros)^ just from their pupa-skins, were brought in. Beetles, moths, larv;i^, and strawberries were among the items. A brood of three young cedar-birds watched by us made an average gain during the first eleven days of 1.13 drams, avoirdupois, i)er bird per day. Excreta, voided on an average of three per hour, averaged to weigh one-sixth of a dram during the same period. Reckoning fifteen hours of activity ^ The Home Life of Wild Birds, p. 21.

Addiii^^ tlie daily gain to the daily exeretion gives 8.6 drams, the daily food during tlie eleven days. After the eleventh day more nutrition goes into feathers and less to flesh, so that the gain in weight is not so great as before ; but the excreta continue to increase in proportion to the bird's development, and the parents are in constant attendance, so it is clear that there is at least no diminution in the food supply after the eleventh day. During the fifteen days that the young birds spent in the nest, they devoured not less than ten ounces apiece, — more than ten times their weight on the day of flight. Another cedar-bird taken after it had left the nest, and kept under sur- veillance but not confined, took a good-sized black or choke cherry every ten minutes. When given two, he invariably doubled the time between meals. This bird was captured at night. The next morning the character of its excrement indicated that there was little or no food matter in the diges- tive organs. The fast was broken by two black cherries ; the stones were dropped forty-five minutes later. A blackberry was digested in half an hour. The cherries were given entire, and their large size evidently delayed their passage from the oesophagus into the proventriculus, for the bird stretched his neck as if in distress after they had been swallowed awhile.

Owen has recorded^ son:ie interesting obser- vations on the food of a young hermit thrush recently from the nest. It ate regularly half its Aveight of raw beefsteak each day, and probably would have taken as much more had it been fed at sufficiently frequent intervals. Perhaps the most interesting point brought out was a method of deter- mining the rapidity of digestion in young birds. Having noticed that the blueberries eaten dyed the excrement, it oc- curred to Mr. Owen that " this fact furnished a ready method of finding the length of time required by the thrush to digest blueberries. The test was made July 26. At 12.56 p.m. of that day, the bird voided while excrement and was fed at once with blueberries. At 2.28 p.m., one hour and thirty- two minutes later, it dropped blue excrement mingled with berry seeds. If this experiment was trust wort liy, and I see no reason to doubt the accuracy of the method, the time re- quired for a blueberry to traverse the digestive tract was, practically, one hour and a half" A brood of young cedar-birds confined by Mr. Frank Bolles^ and fed by the old birds were supplied with eight thousand four hundred cherries in twelve days. Tliree robins about ten days old observed by us were fed in two hours one bird-cherry (P. ijcmisijlrdtuca)^ one large cricket ((fri//!i(s), one smooth caterpillar an inch and a half long, one molh {Xocfiiid), one harvest-man (Phalaru/lukc)^ one tumble-bug (Copris), two earthworms (Liunbricus), two carabid beetles, twenty-nine grasshoppers (AcrUUidce), and eight small creatures thought to be spiders but which could not be made out willi certainly. These forty-seven items were brought at thirty visits between 4.0-1: and 6.03 a.m. During the middle of the day the old birds came less often. Im'- tween 10 and 10.30 there were four visits, from 1.25 to 1.51 ^ The Auk, vol. xiv. pp. 1-8. 2 Id., 1890, vol. vii. p. 290. THE AMOUNT OF FOOD CONSUMED BY BIRDS. 65 there were six, uiid Iroiii '1 to '■) there were six. Ten visits per huiir was (he averui^o the duy through. Over tliree-fourths of the food brouglit consisted of adult grasshoppers, the great Carolina locust being often among them. Half of the time two Avere brought at a visit. Only a little calculation is necessary to show that each occupant of the nest consumed about eighty insects that day, of which at least sixty were grasshoppers. An average red-legged locust — the species most commonly brought — weighs five grains Troy ; sixty of them would weigh three hundred grains, and adding the twenty-live per cent, consisting of worms, beetles, berries, etc., we have four hundred grains as the weight consumed by each nestling on that particular day. They were then about ten days old : their average weight was seven hundred and eleven grains. Thus it appears that they ate per diem more than half their own weight. Mr. Charles W. Nash ^ gives this experience with the food of a young robin : "In May, 1889, I noticed a pair of robins digging out cutworms in my garden, which was infested with them, and saw they were carrying them to their nest in a tree close by. On the 21st of that month I found one of the young on the ground, it having fallen out of the nest, and in order to see how much insect food it required daily I took it to my house and raised it by hand. Up to the 6th of June it had eaten from fifty to seventy cutworms and earthworms ever}^ day. On the 9th of June I weighed the bird ; its weight was exactly three ounces ; and then I tried how much it would eat, it being now quite able to feed itself. With the assistance of my ciiildren I gathered a large number of cut- worms and gave them to the robin after weighing them. In the course of that day it ate just five and one-half ounces of cutworms. Tl^.ese grubs averaged thirty to the ounce, so the young robin ate one hundred and sixty-five cutworms in one ^ Birds of Ontario, p. 22. 5 66 BIRDS L\ THEIR RELATIONS TO MAN. day. Had it been at liberty it would probably have eaten some insects of other species and fewer cutworms, but this shows about what each young robin requires for its main- tenance when growing ; the adult birds require much less, of course. The average number of young raised by a robin is four, and there are usually two broods in the season. A very simple calculation will give a good idea of the number of insects destroyed while the young are in the nest." Five young goldfinches which we watched were from the beginning fed by their parents almost exclusively upon seeds of the bull-thistle (Cnicus pumllus, Torr.). At the age of one week rather more than the product of one thistle-head was divided among them at each meal. They were fed every half-hour on an average, the old birds feeding independently. Not less than thirty thistle-heads were thus consumed in a day by these young birds when they were scarcely more than half-grown. A family of four song-sparrows seven days old received seventeen grasshopper nymphs, from five-eighths to three- fourths of an inch long, and two spiders between 1.55 and 3.02 P.M. — sixty-seven minutes. As they were out of the nest the next day, it may be accepted that they are hearty eaters. Eight days is a short time for the accomplishment of so great a chaage. A brown thrasher at ten visits made in one hundred and twenty-six minutes delivered to one of her young just out of the nest one spider, one earthworm, one hairy caterpillar an inch and a half long, two Carolina locusts, seven red-legged locusts, and three other insects which were not identified. A bobolink brought to two fiedglings between 5.13 and 5.33 one afternoon, — twenty minutes, — nine grasshoppers. The next morning between 9.18 and 10.05, — forty-seven minutes, — ten grasshoppers were brought. About that time one of the young birds escaped. To the remaining one he fed eleven grasshoppers in two hours. Of the thirty 'hoppers THE AMOUNT OF FOOD CONSUMED BY BIRDS. 67 all but two were green, some belonging to the family Acri- diidce and others to the family Locustkke. Dr. Sylvester D. Judd/ from an observation on the food of three young house-wrens about three-fourths grown, reports that ''The mother made one hundred and ten visits to her little ones in four hours and thirty-seven minutes, and fed them one hundred and eleven spiders and insects. Among these were identified one white grub, one soldier-bug, three millers {NoctuidcE), nine spiders, nine grasshoppers, fifteen May-flies, and thirty-four caterpillars. On the following day similar observations Avere made from 9.35 a.m. till 12.40 p.m., and in the three hours and five minutes the young were fed sixty-seven times. Spiders were identified in four instances, grasshoppers in five, May-flies in seventeen, and caterpillars in twenty.'' Four chipping-sparrows about five days old devoured thirty-seven grasshoppers, several of which were adults, but most of them half-grown nymphs, between 4.37 and 6.06 p.m., — eighty-nine minutes. The next morning between 9.56 and 10.45, — forty-nine minutes, — they ate eighteen grasshoppers and two full-grown measuring worms (Cingllia). A single young chippy lately out of the nest was seen to take food — grasshoppers chiefly — thirty times in sixty-five minutes. A brood of three chii)ping-sparrows watched by us one entire day received food one hundred and eighty-seven times. It was not possible to determine the exact nature of all that was brought, but it appeared to be wholly insectivorous, cut- worms and otlier caterpillars being often observed.- These observations are certainly sufficient to establish the fact that birds as a class consume an enormous amounl of food.

It is well known that, as a rule, the most damage to culti- vated crops is done by the species of insects and other noxious animals which fluctuate greatly in numbers. In this chapter we have to determine whether in the presence of an extraordinary abundance of a given edible animal birds vary their food ratios by taking unusual numbers of the species in question. If they do, it is evident that they assist in reducing the pest to its normal limit ; if they do not, they neglect an opportunity for usefulness. Four examples may serve to illustrate the tendencies of birds under sucli conditions. The first relates to the canker- worm, the second to the Rocky Mountain locust, the third to the army-worm, and the fourth to the European vole, or field- mouse. A few years ago a large apple-orchard in central Illinois was severely attacked by canker-worms. As a result of their depredations a considerable part of the orchard had the ap- pearance at a little distance of having been ruined by fire. To determine whether the birds of the region were exerting themselves to check this outbreak, Professor S. A. Forbes visited the orchard for two successive seasons, shooting each time a number of birds of the various species present. The stomach contents of these were afterward carefully examined : from the published record ^ of the results we have made the following sunnnary. ^ Bulletin of the Illinois State Laboratory of Natural History, vol. i., No. G. as UK ( A'i-mj{i). nillDS AS KKdn^ATorvS (»F olTlUiEAKS. r;9 Nine robins had eaten only animal lood, ol' whicli canker- worms formed twenty, cutworms twenty-eight, and vine- chafers fourteen per cent., making a total of sixty-two per APPLE-LEAVES ATTACKED BV CANKER-WOR.M.- cent. for these three groups of insects. Eleven per cent, of the remainder consisted of click-beetles [Elateridce). Fourteen cat-birds were examined : they had eaten fifteen per cent, of canker-worms, ten per cent, of cutworms and other cater- pillars, fourteen per cent, of ants, and thirty-three per cent, of vine-chafers. Four brown thrushes had eaten canker- worms, vine-chafers, June-beetles, click-beetles, ground-beetles, and other insects. Combining these food elements of twenty- seven members of the thrush family. Professor Forbes found that 'Mione of them had oaten any vegetation whatever; that ninety-six per cent, of their food consisted of insects (myriapods and earthworms making up the remaining four per cent.) ; that sixteen per cent, was canker-worms, and only four per cent, predaceous beetles." The vine-chafer made just twenty-five per cent, of the entire food. The most important element in the food of five bluebirds was the vine-chafer (thirty-six per cent.), while canker-worms formed twelve per cent. Two black-capped chickadees had 70 r3IRDS IX THEIR RELATIONS TO MAN. eaten only canker-worms and beetles, tlie former makin^f sixty-one per cent, of the food and the latter belonging principally to a wood-boring beetle of the genus Psenocerus. Nearly half of the food of several house- wrens consisted of canker- worms. Passing now to the warbl ers (3Liiotiltldce), we come to many spe- cies feeding largely on canker-worms. Four- fifths of the food of a single Tennessee w^ar- bler consisted of these insects. Two-thirds of that of five sum- mer yellows-birds was canker-w o r m s, and tlie same was true of two chestnut-sided warblers and also of four black-poll war- blers. A single black- throated green war- bler had eaten seventy per cent, of canker-worms, and two Maryland yellow-throats had eaten forty per cent, of these and forty per cent, of other caterpillars. Consequently canker- worms composed nearly or quite two-thirds of the food of these fifteen warblers. Seventy-nine per cent, of the food of three warbling vireos consisted of caterpillars, more than half of them being canker-worms. Out of a flock of about thirty cherry-birds, or cedar wax- wings, seven birds were shot. With the exception of a few Aphodii (small beetles) '' eaten by three of the birds in THE BIAEBIKD. BIRDS AS REGULATORS OF OUTBREAKS. 71 numbers too insignificant to figure in the ratios, the entire food of all these birds consisted of canker-worms, Avhich therefore stand at an average of one hundred per cent. The number in each stomach determined by actual count ranged from seventy to one hundred and one, and was usually nearly one hundred. Assuming that these constituted a whole day's food, the thirty birds were destroying three thousand worms a day, or ninety thousand for the month during which the caterpillar is exposed." A specimen each of the cliff-swallow, American gold- finch, and yellow-winged sparrow had eaten no canker-worms. About one-third of the food of eight chipping-sparrows con- sisted of caterpillars, half of them being canker-worms. Three field-sparrows had eaten largely of canker-worms and various beetles, forty-three per cent, of the food of fourteen black-throated buntings consisted of canker-worms, and a very few of these worms had been eaten by two rose-breasted grosbeaks ; they also formed fifty-nine per cent, of the food of eighteen indigo-birds. No canker-worms were found in the stomachs of a single cow-bird and two red-winged blackbirds. Three Baltimore orioles, however, had eaten forty per cent, of these worms and fifty per cent, of vine-chafers. Two orchard-orioles made even a better showing. " More than three-fourths of the food of these consisted of canker-worms, and other caterpillars made an additional twenty per cent.*' Three bronzed grackles had eaten no caterpillars. Passing now to the family of flycatchers we find that more than one-fourth of the food of three kingbirds consisted of canker-worms and fully one-half of vine-chafers. The food of three wood-pewees consisted entirely of Hying insects. Two specimens of Trailfs flycatcher had calcn twenty-live per cent, of canker-worms, and a single yellow-bellied fly- catcher had eaten an equal percentage of vinc-chaters but no canker-worms. A single black-billed cuckoo had eaten of 72 BIRDS IN THEIR RELATIONS TO MAN. canker-worms seventy-five per cent., other caterpillars twenty per cent., and vine-chafers five per cent. Four red-headed woodpeckers had eaten fifteen per cent, of canker-w^orms, while a single golden-winged woodpecker had eaten only ants. No canker-worms were found in one mourning-dove and two quails. Summarizing the above results into one general statement, it is found that one hundred and forty-one specimens be- longing to thirty-six species were studied. '• Twenty-six of these species had been eating canker-worms, which were found in the stomachs of eighty-five specimens, — that is to say, seventy-two per cent, of the species and sixty per cent, of the specimens had eaten the worms. Taking the entire assemblage of one hundred and forty-one birds as one group, we find that thirty-five per cent, of their food consisted of canker-worms." A comparison was made, in the case of the robin, cat-bird, black-throated bunting, and indigo-bird, of the food in this orchard and that of the species during May under ordinary circumstances. These results showed that there Avas a gen- eral diminution of vegetable and miscellaneous food in the orchard specimens to compensate for the increase of cater- pillars. "Three facts,'' says Professor Forbes, "stand out very clearly as the result of these investigations : "(1) Birds of the most varied character and habits, migrant and resident, of all sizes from the tiny wren to the blue-jay, birds of the forest, garden, and meadow, those of arboreal and those of terrestrial habits, Avere certainly either attracted or detained here by the bountiful supply of insect food and were feeding freely upon the species most abundant. That thirty-five per cent, of the food of the birds congregated here should have consisted of a single species of insect is a fact so extraordinary that its meaning cannol ])e mistaken. Whatever i^ower the birds (jf this vicinity possessed as checks BIRDS AS REGLLATOFiS OF OUTBREAKS. "3 upon destructive irruptions of insect life was bein^' largely exerted here to restore the broken balance of organic nature. And while looking for their influence over one insect outbreak we stumbled upon at least two others, less marked, jxTliaps incipient, but evident enough to express themselves clearly in the changed food ratios of the birds. '• (2) The comparisons made show plainly that the rellex effect of this concentration on two or three unusually lui- merous insects was so widely distributed over the ordinary elements of their food that no especial chance was given for tlie rise of new fluctuations among the species commonly eaten. That is to say, the abnormal pressure put upon the canker-worm and the vine-chafer was compensate(t by a gen- eral diminution of the ratios of all the other elements, and not by a neglect of one or two alone. If the latter had been the case, the criticism might easily have been made that the birds in helping to reduce one oscillation were setting others on foot. '• (3) The fact that, with the exception of the indigo-bird, the species whose records in the orchard were compared with those made elsewhere had eaten in the former situation as many caterpillars other than canker-worms as usual, simply adding their canker-worm ratios to those of otlier caterpil- lars, goes to show that these insects are favorites with a majority of birds.'' One of the most notable series of studies of the relation of birds to outbreaks of injurious insects was tliat carried on for thirteen years by Professor Samuel Aughey, of the Uni- versity of Nebraska, concerning the extent to which birds feed upon the Rocky Mountain locust or grasshopper during the periodic outbreaks of that insect. Fortunately, the results of these studies have been preserved by the United States Entomoloorical Commission.* Between 1865 and l First R.'poif. AppriMJix II. 74 BIRDS IN THEIR RELATIONS TO MAN. fessor Aughey made a careful investigation of this subject, both by out-door observations of Uving birds and by in-door examinations of stomach contents. His tabulated results show conclusively that birds of all kinds Avere doing their best to reduce the numbers of the locusts. A brief summary of the principal facts will indicate the truth of this. Beginning with the thrushes and their allies, we find that six robins had eaten two hundred and sixty-five locusts, three wood-thrushes had taken sixty-eight locusts, one hermit-thrush contained nineteen locusts, two olive-backed thrushes were responsible for the death of fifty-five 'hoppers, while two AVilson's thrushes had destroyed seventy-three more. Five cat-birds had eaten one hundred and fifty-two of these insects. Sixty-seven locusts were taken from the stomachs of three bluebirds and twenty-nine from one little ruby-crowned kinglet, while four tufted titmice yielded two hundred and fifty of the pests and nine long-tailed chickadees contained four hundred and eighty-one of them. Four slender-billed nuthatches — the western representative of the white-breasted nuthatch — had eaten ninety-three locusts. Even the little warblers ate many of the pests, naturally choosing the younger specimens. Seven golden warblers had taken sev- enty-seven locusts and one hundred and seventy-six other insects. Five black-throated green warblers contained one hundred and sixteen 'hoppers and one hundred and four other insects. Four black-poll warblers had eaten one hundred and twenty-three locusts, varying their diet with forty-seven insects of other kinds. Eight prairie- warblers devoured one hundred and sixteen of the locusts and a greater number of other insects ; while the golden-crowned thrush had fed upon both the 'hoppers and their eggs. Many warblers were seen feeding their nestlings with young locusts. While the warblers paid most attention to the immature grasshoppers, the swallows fed chiefly u})on the adult winged BIRDS AS REGULATORS OF OUTBREAKS. 75 insects, probably catcliiii^' llieiii in I lie air. Seven l)arn- swallows had eaten one hundred and thh'ly-iiiiie, eight eaves- swallows three hundred and twenty-six, five bank-swallows one hundred and four, and ten ])ur|)l(' martins two hundred and sixty-five locusts. The vireos and shrikes were found to eat many of the pests, while some of the grosbeaks and finches ate the eggs as well as the 'hoppers. Three bobolinks had devoured an average of fourteen locusts each, while nine meadow-larks had taken two hundred and thirteen of the pests besides some of their eggs. Fifty-one locusts were taken from the stomach of a single yellow-headed blackbird, while the Balthnore oriole, Brew^er's blackbird, and the purple grackle were noted as feeding almost exclusively upon the pests when the latter were abundant. Even the raven, the crow, the magpie, and the blue-jay fol- lowed the prevailing fashion in the feathered world, eating large numbers of the locusts, although no doubt they did not wholly neglect the occupants of any of the nests of the smaller birds with which they came in contact. The flycatch- ers and pewees proved to be doing good service, while the stomachs of the whippoorwill and nighthawk were crowded with 'hoppers, three hundred and forty-eight being taken from seven specimens of the latter species. It seems almost incredible that the tiny ruby-throated hum- ming-bird should also have followed the fashion, yet Professor Aughey assures us that a specimen caught by a cat '• had four small locusts in its stomach." After this we are prepared to learn that the stately kingfisher varies his scaly diet with an occasional 'hopper. Nor is it surprising that ten specimens of the highly insectivorous yellow-billed cuckoo had eaten four hundred and sixteen locusts as well as one hundred and fifty-two other insects. The woodpeckers evidently varied tlieir usual diet to an extraordinary degree on account of the presence of the grass- 7(; BIRDS IX THEIR RELATIOXS TO MAN. hoppers. Six hairy woodpeckers had taken one hundred and fifty-seven locusts and one hundred and ninety-three other insects ; four downy woodpeckers had eaten one hundred and sixty-five locusts and ninety other insects; five yellow-bellied woodpeckers contained one hundred and thirty 'hoppers and ninety-three specimens of other species ; six red-headed wood- peckers had devoured one hundred and forty-nine locusts and two hundred other insects ; while eight flickers contained two hundred and fifty-two of the 'hoppers together with one hun- dred and forty-nine insects of other species. The extent to which birds of prey fed upon the locusts would surprise the many people who look upon hawks and owls only as eneniies of the poultry-yard, deserving extermi- nation. One barn-owl had eaten thirty-nine locusts, twenty- two other insects, and a mouse. Eight screech-owls contained two hundred and nineteen 'hoppers and many other insects, while nine burrowing owls had devoured three hundred and eighteen locusts. The hawks patterned after the owls ; six marsh-hawks ate two hundred and forty-nine locusts, while two Swainson's buzzards had devoured one hundred and twenty-nine of the pests. Even the pigeons and the gallinaceous birds which usually feed so largely upon grains and seeds added a considerable pro- portion of locusts to their diet. Professor Aughey wTites that in locust years the wild turkey makes the pest its principal food. Four sage-cocks had eaten one hundred and ninety grasshoppers, while the sharp-tailed grouse, prairie-hen, and quail ate enormous numbers of them. Passing now to the shore birds, the records of the golden l)lover, the American snipe, the various sand-pipers, godwits, tattlers, and curlews all tell the same story of locust destruc- tion. Even the great blue-heron, American bittern, and sand- hill crane devoured the pests, while the rails and American coot added their efforts to subdue them. The snow-goose, the Canada goose, and the various ducks — including the mal- BIRDS AS REGULATORS OF OLTBREAKS. 77 lard, dusky duck, pintail, and blue- winged teal — contained quantities of 'hoppers. Two out of five white pelicans exam- ined had varied their diet of crayfish and frogs by picking up locusts, one containing forty-one and the other sixty-seven specimens. The gulls — inc hiding the black-backed, herring, ring-billed, and Franklin's rosy gull — had eaten many grasshoppers, as had also the least and the black tern. It certainly Avould be difficult to obtain more striking evi- dence than this concerning the utility of birds in checking out- breaks of injurious insects. The fact that birds of all sorts and sizes, from the giant pelican to the tiny humming-bird, — ^birds of the prairie, the forest, the air, the shore, the sea, and the inland lake, — fed so largely upon the locusts proves beyond doubt that these feathered allies were using to the fullest extent a tremendous force to check the ranks of the invaders. A few years ago the army-worm appeared in great num- bers in Pennsylvania, causing much damage to field crops. The State zoologist. Professor B. H. Warren, made a careful series of investigations to determine the extent to which birds fed upon the pests. The results showed that a large propor- tion of the common birds devoured them eagerly. Crows, blackbirds, robins, cat-birds, thrushes, meadow-larks, and bluebirds were found to get a large part of their food from the hosts of the army-worms. Kill-deers, sand-pipers, and sparrows also fed freely upon them, while the screech-owl and the sparrow-hawk devoured great numbers of the pests. Insects, however, are not the only animals against whose undue increase the agriculturist needs protection. In many parts of Europe there have been for centuries i)eriodic out- breaks of field-mice that have caused enormous injury. The species oftenest concerned appears to be the short-tailed lield- mouse [Arvicola ag)'esfis;), related to the common meadow- mice of the United Stales. There is abundant evidence tliat 78 BIRDS IN THEIR RELATIONS TO MAN. at the times of such uprisings the birds of prey flock to the in- fested fields in great numbers. More than three centuries ago this fact was noticed, as is shown by the following paragraph from Stow's " Chronicle :'" "About Hallontide last past (1581), in the marshes of Danesey Hundred, in the county of Essex, there suddenly appeared an infinite number of mice, which overwhelming the whole earth in the said marshes did shear and gnawe the grass by the roots, spoyling and tainting the same with their venomous teeth in such sort that the cattell which grazed thereon were smitten with a murrain ; which vermine by policy of man could not be destroyed, till at last it came to pass that there flocked together such a number of owls as all tlie shire was able to yield, whereby the marsh holders Avere shortly delivered from the vexation of said mice. The like of this was also in Kent." Another '-sore i)lague of strange mice" occurred in Essex in 1648. In 1754 a correspondent of the (lenflvnuin'x M(i(/(t- z'lne wrote from Market Downham, England : '- Once in about six or seven years Helgay, about one thousand acres, is in- fested with an incredible number of field-mice, which like locusts devour the corn of every kind. Invariably there follows a prodigious flight of Norway owls, and they tarry until the mice are evidently destroyed by them." Similar testimony exists concerning the more recent out- breaks. That of 1875-6 — one of unusual severity, in which one-third of the pastures of the affected district were de- stroyed — was attributed partly to a series of mild winters and partly to the destruction of predacous birds and mammals. A recent English writer, Dr. W. B. Wall, says that '-the chief enemies of the voles are the short-eared owl and the kestrel hawk, which will do more to reduce their ranks than all the traps of the agriculturist and the microbes of the scientist combined. The kestrel hawk is known to all, duly appreciated by a few. but still destroyed by too many. The BIHDS AS RKGULATURS OF OCTHRKAKS. 79 short-eared owl is one of our most valuable wiuler visitors, arriving about October and leaving usually in Marcli. It fre- quents open moors, alights and secretes itself on the ground in preference to trees, and feeds by day as well as in the evening. In this winter of 1887-8 the moors were crowded with these birds, it being no uncommon occurrence to start two or more at the same time from the long grass ; the ex- planation of their numbers no doubt being that the preceding dry summer had been most favorable to the increase of the animal life of the moors, which supplied ample food and in- ducements for the birds to congregate.'' Mr. W. H. Hudson, in his fascinating book, '' The Natu- ralist in La Plata," gives a graphic account of the suppression of an outbreak of mice on the pampas of South America. These little creatures had increased to an enormous extent, and animals of many kinds lived upon them. ''In the au- tumn of the year countless numbers of storks [Ciconia mcuj- nari) and of short-eared owds made their appearance. They also came to assist at the general feast." The mice were soon reduced in numbers to a point far below their normal limit. A similar abundance of birds is noticed, Mr. Hud- son says, w^henever other animals — grasshoppers, crickets, or frogs — become excessively numerous on the i)ampas. He explains the concentration of these birds — usually seldom seen — upon the S})ot wliere food abounds by the statement that wiien not breeding they a,re constantly travelling in search of food. Hying at great heights and covering a large territory in their wanderings. " When the favorite food of any one of these species is plentiful in any particular region, all the individuals that discover it remain and attract to them all of their kind passing overhead. This hap})ened in the pampas with the stork, the short-eared owl, the hooded gull, and the dominican or black-backed gull, — the leading si)e(ies among the feathered nomads; a few first appear like harbingers; these are presently joined by new-comers in considerable 80 BIRDS I\ THEIR RELATIONS TO MAN. numbers, and before long they are in myriads. Inconceivable numbers of birds are doubtless in these n^sjrions continually passing over us unseen, '' In the presence of an unusual abundance of food the rate of increase of some birds becomes greater. It has been noticed that owls multiply rapidly when outbreaks of mice occur. Testimony of this kind could be multiplied indefinitely : it unquestionably is sufficient to demonstrate that when an out- break of mice or similar pests occurs the hawks and owls find an abundant food supply, of which they readily avail them- selves, and in so doing check to a great extent the damage that might be done. The evidence furnished by these examples suffices to show^ that birds do exert a decided influence in checking unusual outbreaks of injurious animals. They have been well likened to a great standing army which may be concentrated at short notice upon any locality where an outbreak occurs. CHIl'lMNC- CHAPTER VII. THE RELATIONS OF BIRDS TO r'REDACEOUS AND IWRASITIC INSECTS. The attempt is frequently made (o ])elittle the usefulness of birds by tlie argument that they do as nuu-li harm l)y feed- ing upon predaeeous and parasitic insects as they do good by devouring the injurious ones. For example, B. D. Walsh, the first State Entomologist of Illinois, claimed that a bird must eat at least thirty injurious insects for every beneficial one in order to be of economic value ; and since then similar arguments have frequently been used. During the last few years students of bird food have commonly placed the results of their studies under these headings : " Beneficial," " In- jurious," "Neutral ;" including in the former all parasitic and predaceous insects. Before proceeding to a general discussion of the principles which underlie this whole subject, the ab- surdity of this assumption may easily be shown. Suppose an ichneumon parasite is found in the stomach of a robin or other bird : it may belong to any one of the following cate- gories : (1) The primary parasite of an injurious insect. (2) The secondary parasite (jf an injurious insect. (3) The primary parasite of an insect feeding on a no.xious plant. (4) The secondary parasite of an insect feeding on a nox- ious plant. (5) The primary })arasite of an insect feeding on a wild plant of no economic value. (6) The secondary parasite of an inscd feeding on a wild plant of no economic value. (7) The primary parasite of a j)redaceous insect. 6 81 82 BIRDS TX THEIR RELATIONS TO MAN. (8) The primary parasite of a spider or spider's egg. This Ust might easily be extended still farther, and the assumption that the parasite belongs to the first of these categories is unwarranted by the facts and does violence to the probabilities of the case. A correct idea of the economic rd/e of the feathered tribes may be obtained only by a broader view of nature's methods, — a view in which we must ever keep before the mind's eye the fact that all the parts of the organic world, from monad to man, are linked together in a thousand ways, the net result being that unstable equilibrium conmionly called " the bal- ance of nature." The fact that in eating insect parasites birds do not neces- sarily cause an economic loss was first pointed out by Pro- fessor S. A. Forbes in an admirable essay entitled " On some Interactions of Organisms." As we find it impossible to im- prove and difficult to condense the argument there })rinted, we quote the following extended extract. " Evidently a species cannot long maintain itself in numbers greater tlian can find sufficient food year after year. If it is a phytophagous insect, for example, it will soon dwindle if it seriously lessens the numbers of the plants upon which it feeds, either directly by eating ihem up, or indirectly by so weakenhig them that they labor under a marked disadvantage in the struggle with other plants for foothold, light, air, and food. The interest of the insect is therefore identical with the interest of the plant it feeds upon. Whatever injuriously affects the latter, equally injures the former ; and whatever favors the latter, equally favors the former. This must there- fore be regarded as the extreme normal limit of the members of a phytophagous species, a limit such that its depredations shall do no especial harm to the plants upon which it de- pends for food, but shall remove only the excess of foliage or fruit, or else superfluous individuals which must either perish otherwise if not eaten or, surviving, must injure their species BIRDS L\ RELATION TO PARASITIC INSECTS. 83 by overcrowding'. If the plant-feeder multiply beyond the above limit, evidently the diminution of the food supply will soon react to diminish its own numbers, a counter reaction will then take place in favor of the plant, and so on through an oscillation of indefinite continuance. ''On the other hand, the reduction of the i)liytophagous insect below the normal number will evidently injure the food plant by preventing a reduction of its excess of growth or numbers, and will also set up an oscillation like the pre- ceding except that the steps will be taken in reverse order. " I next point out the fact that precisely the same reason- ing applies to predaceous and parasitic insects. Their inter- ests also are identical with the interests of the species they parasitize or prey upon. A diminution of their food reacts to (hminish their own numbers. They are thus vitally inter- ested in confining their depredations to the excess of indi- viduals produced or to redundant or otherwise unessential structures. It is only by a sort of unlucky accident that a destructive species really injures the species preyed upon. '' The discussion thus far has affected only such organisms as are confined to a single species. It remains to see how it applies to such as have several sources of support open to them, — such, for instance, as feed indifferently upon several plants or upon a variety of animals or both. Let us take, first, the case of a predaceous beetle feeding upon a variety of other insects, — either indifterently upon whatever species is most numerous or most accessible, or preferably upon cer- tain species, resorting to others only in case of an insufficiency of its favorite food. '' It is at once evident that, taking its food-insects as a unit, the same reasoning applies as if it were restricted to a single species for food : that is, it is interested in the maintenance of these food-species at the highest number consistent with the general conditions of the environment, interested to con- fine its own depredations to that suri)lus of its food which 84 BIRDS IN THEIR RELATIONS TO MAN. would otherwise perish if not eaten, interested, therefore, in estabhshing a rate of reproduction for itself which will not unduly lessen its food supply. Its interest in the numbers of each species of the group it eats will evidently be the same as its interest in the group as a whole, since the group as a whole can be kept at the highest number possible only by keeping each species at the highest number possible." Professor Forbes goes on to show that when the rate of reproduction of a parasite is relatively too great it causes fluctuations in numbers which are injurious both to the parasite and its host, and concludes that in a state of nature " the annihilation of all the established enemies of a species would, as a rule, have no effect to increase its Ihial average numbers." Such being the case Avhere man has not interfered with nature, we have next to inquire to what extent these princi- ples hold good, under the conditions of modern agriculture, for those insects which feed upon cultivated crops. Evidently a chief element of disturbance of the natural order here lies in the enormously increased food supply, an increase so great and so subject to nmltiplication by man that it is a rare event for an insect to reach its limit. If a crop in a given locality is destroyed by insects, seed from another region is usually planted the following season, so that, while under natural conditions the insect would have been starved out, it is instead given an increased opportunity to develop. In consequence of this, the law that no animal can nmltiply beyond the limits of its food supply becomes practically inoperative. But while this is true of the plant-feeding species, it is not true of the parasite that preys upon it. The latter is still under the o})eration of the primal food law : when it has reduced the numbers of its host to a point where it nmst cease to multiply because there are no caterpillars in which to deposit its eggs, man does not step in and furnish a supply of caierpillars to kee}) u}) the activities of the parasite. Con- BIKDS l.\ lll"]LATl().\ TO I'AKASITIC IXSKCTS. sTj seqaently there is a great and sudden decrease of the nuiubers of the parasite. In other words, while the law that no species can multiply beyond the limits of its food supply is rendered inoperative in the case of the host caterpillar, it conthiues to act in the case of the parasite, because man does not artificially increase the food supply of the latter. Man's interposition evidently has the effect of extending and intensifying the oscillations which would occur under natural conditions. We must next determine the probable effect produced when a bird eats some of these parasites. It need hardly be said that the species of insects which live exposed are very much more likely to be eaten by birds when they are unusually abundant than when not numerous. When a hymenopterous parasite is found in a bird's stomach, the chances are greatly in favor of the assumption that the species to which it belongs is at the time more numerous than usual. The destruction of a portion of the parasites may not only involve no loss from an economic point of view, but may actually be a bene- fit, in that it will extend the period of effective operation of the parasite, and put off the time when it will cut off its own food supply by its too rapid increase. The probabilities do not justify the assumption that a bird usually does harm rather than good in eating a parasite of an injurious phy- tophagous insect. Nothing has been said in regard to those parasites upon parasites which are called the secondary or hyper-parasites ot noxious insects. Our knowledge of the precise biological relations of these is limited. On general principles it is prob- able tliat when a bird eats one of these it is at least as likely to be doing man a benefit as an injury.' ^ For an account of the relations between hymenopterous parasites and tlieir hosts, see Fiske, "The Parasites of the Tent Caterpillar," New Hampshire CoUe^'e Airricultural Exp. Station, Technical Bulletin, No. 6. CHAPTER VIII. THE THRUSHES AND THEIR ALLIES. THE BLUEBIRD. There is, perhaps, no feathered songster which has so endeared itself to the people of the northern United States as the bluebird. Clad in modest but beautiful colors, endowed with a voice of plaintive melody, and familiarly associating with man, it is one of the most delightful harbingers of spring. THE BLVEBIRD. [After Biologiod Survey.) Its insect-eating habits are well known, for the bird may often be seen flitting from its perch in chase of some passing moth or grasshopi)er. The food of one hundred and eight Illinois specimens, taken in every month of the year except Novem- ber and January, was studied by Professor S. A. Forbes. In February cutworms and ichneumon-flies formed the most important elements of th(^ food, twenty-four per cent, of the 86 THE THRUSHES AND THEUi ALLIES. 87 former and twenty-two per cent, of the latter having been eaten. The larvte of the two-lined soldier-beetle, a pre- daceous species, had been eaten to the extent of eight per cent, and young grasshoppers to the extent of nine per cent. Ground-beetles formed five per cent, of the food, soldier-bugs seven per cent., spiders and crickets each four per cent. The ratios of parasitic and predaceous species were very high, these making thirty-nine per cent, of total food for the month. In March thirty-eight per cent, of cutworms and related caterpillars, part of them being army-worms, and one per cent, of crickets and grasshoppers were eaten. In April large numbers of small dung-beetles were present in the stomachs. Eight per cent, of ground-beetles, nine per cent, of spiders, and twenty-one per cent, of caterpillars were also present. The number of spiders eaten in May was unusual, these forming twenty-one per cent, of the food. Moths, caterpillars, June-beetles, and grasshoppers had been eaten freely this month, forming fifty-five per cent, of the stomach contents. In June winged ants and various spiders had been eaten, as well as measuring worms and ground-beetles. A few birds had eaten a small number of raspberries and goose- berries. The most remarkable elements of the food in July con- sisted of grasshoppers and crickets (twenty-seven per cent.) and June-beetles (twelve per cent.). Caterpillars, ground- beetles, and spiders composed the more important parts of the remainder. The chief business of the month of August was the pursuit of locusts, crickets, grasshoppers, moths, and caterpillars. The three first named amounted to more than half of the food for the month, and the moths and caterpil- lars to more than one-fourth. The only fruits present were a few wild cherries and elder-berries. In September \\\o common red-legged grasshopi)er was largely eaten. This and rclulrd grasshoppers, together with 88 BIRDS L\ THEIFi RELATIONS TO MAN. cutworm-like caterpillars, formed almost nine-tenths of the food for the month. The bluebird winters to a considerable extent in southern Illinois, where its food consists A^cTy largely of wild fruits, especially the berries of the mistletoe. A few beetles, bugs, and spiders fill out the Avinter bill of fare. In the case of six young bluebirds yet in the nest, though well feathered. Dr. Judd found that the food consisted of ''beetles, caterpillars, grasshoppers, spiders, and a few snails." Although the bluebird eats a large percentage of preda- ceous and parasitic species that are often considered bene- ficial to man, the probabilities are largely in favor of the assumption that in devouring these the bird is assisting in keeping up a proper balance of organic forces, while in eating the insects injurious to crops it is doing a very great good. Professor Forbes estimates that '' one hundred bluebirds at thirty insects each a day would eat iu eight months about six hundred and seventy thousand insects. If this nundDer of birds were destroyed, the result would be the preservation, on the area supervised by them, of about seventy thousand motlis and caterpillars (many of them cutworms), twelve thousand leaf-hoppers, ten thousand curculios, and sixty-five thousand crickets, locusts, and grasshoppers. How this frightful horde of marauder's would busy itself if left undis- turbed no one can doubt. It would eat grass and clover, and corn and cabbage, inflicting an immense injury itself, and leaving a progeny which would nmltiply that injury indefi- nitely. The bluebird is easily encouraged on the home grounds and will well repay a little trouble in furnishing nesting sites. It breeds readily in boxes and bird-houses, and if these are provided in a])undance it seems likely that the numbers of the birds may be materially increased. THE THRUSHES AND THEIR ALLIES. 89 THE ROBIN. With the exception of the English sparrow and possibly the crow, the economic status of no American bird has been discussed so fully and freely as that of the robin. Appear- ing early in spring and remaining late in autumn in regions where it does not reside throughout the year, commonly fre- quenting lawns and meadows, building conspicuous nests near the haunts of man, feeding freely upon the fruits of the garden and orcliard, greeting the rising and the setting sun ~^C79 __— _— ^==^^ THE ROBIN. {AJlcr Biological Survey.) with bursts of no mean melody, — these and other consider- ations have combined to render the robin familiar to every lover of the out-door world. The robin obtains most of its insect food upon the ground, where it searches diligently for cutworms, white grubs, ground-beetles, and allied creatures. One of the most familiar sights of spring in the Northern States is that of dozens of robins searching the grass of lawns and meadows for food. These birds are decidedly gregarious, migrating in flocks of considerable size and remaining together in the 90 BIRDS IN THEIR RELATIONS TO MAN. South during winter. Even during the breeding season the young birds and the old males gather nightly to roost in cer- tain woods. ^ The nest is so well known that we need here only mention its bulky size and the fact that at least two broods of four or five young each are reared during the season. Several studies of the food of the robin are on record. One of the most authoritative of these is that of Professor S. A. Forbes, who made two separate investigations of the food in Illinois : the first included forty-one and the second one hundred and fourteen specimens. We have summarized the results in the latter case as follows : Ninety-nine per cent, of the food of eleven robins shot in February consisted of insects : cutworms and other caterpillars constituted four- teen per cent., and the larvae of the white-winged Bibio^' — a two-winged fly — seventy-six per cent. These Bibio larvae have repeatedly been found in several widely separated States to form the principal food of the robin during spring. The larvae live in colonies of a hundred or more individuals, and generally feed upon decaying organic matter, though some naturalists have stated that they are capable of doing serious injury to grass-lands. Professor Forbes took one hundred and seventy-five Bibio larvte from the stomach of a single robin. In addition to these insects a very few beetles, grasshoppers, bugs, spiders, and thousand-legs had been eaten. About five per cent, of the food was estimated to consist of beneficial insects. Thirty-seven per cent, of the food of nine March robins consisted of Bibio larvae ; cutworms and otlier caterpillars formed thirty per cent. The remaining food elements were ^ For an interesting account of these little-known " robin roosts," see Bradford Torrey's book, "The Footpath Way," and Mr. Brewster's ac- count in Tlie Aul\ October, 1890. ' Bibio albipennis. Say. THE THRUSHES AND THEIR ALLIES. 91 composed of scavenger-beetles, wire-worms, ground-beetles, grasshoppers, and sumach-berries. Six per cent, of the food was considered to belong to beneficial species and thirty- seven per cent, to those injurious. In April caterpillars formed one-fourth of the food and beetles forty-two per cent. " It is in this month that the bird makes its principal attack upon the predaceous beetles, wiiich are represented by an average of seventeen per cent, eaten by eleven birds.'' A few Bibio larva3, earthworms, Orthoptera, bugs, and sumach- berries had also been eaten. " The record of May is sub- stantially a duplicate of the April list, except in a few particu- lars. The Bibio larvae are replaced by seven per cent, of adult crane-flies and the ground-beetles drop to four per cent., the balance being almost replaced by the scavenger- beetles and leaf-chafers. . . . With June the robin revolu- tionizes his commissariat. The insect ratios, Avhich have averaged ninety-five per cent, during the preceding months, now drop to forty-two, and remain at or below this point for the rest of the year; and this lack is compensated by the appearance of fifty-five per cent, of cherries and raspberries. The loss falls chiefly upon the two-winged flies and beetles, the former dropping from eleven per cent, to less than one and the latter from forty-four per cent, to fifteen. The four- teen July birds were evidently revelling in the fruit garden, raspberries, blackberries, and currants forming seventy-nine per cent, of the food." The partial disappearance of fruit supplies in August sent the robhis back to insects, although the twenty birds taken during the month had eaten fifty-six per cent, of fruit. "Cherries made forty-four parts of the food of the month, eaten by fourteen of the birds, hid two- thirds of these cherries were icild. Tame grapes made three per cent, of the food, berries of the mountain-ash about four per cent., and blackberries from the woods not far from five per cent.'' Cutworms, crickets, and grasshoppers are impor- tant insect elements for the month. In September fifteen 92 BIRDS IN THEIR RELATIONS TO MAN. per cent, of winged ants were eaten and seventy per cent, of fruits, more than half of the fruits being grapes and the re- mainder berries of the moon-seed and mountain-asli. Dur- ing October and later months large numbers of wild grapes were eaten. Taking the year as a whole, insects form almost two-thirds of the food of the robin. In the investigations of the United States Department of Agriculture three hundred and thirty stomachs of the robin have been examined. In the summary of the results, by Professor F. E. L. Beal, it is said that more than forty-two per cent, of its food consists of animal matter, chiefly insects, the rest being composed for the most part of small fruits and berries, largely of wild sorts. Noxious insects are believed to constitute at least one-third of the robin's food, grasshop- pers alone forming ten per cent, of all the material eaten. " Vegetable food forms nearly fifty-eight per cent, of the stomach contents, over forty-seven per cent, being wild fruits, and only a little more than four per cent, being possibly cul- tivated varieties. Cultivated fruit amounting to about twenty- five per cent, was found in the stomachs in June and July, but only a trifle in August. Wild fruit, on the contrary, is eaten in every month and constitutes a staple food during half the year. No less than forty-one species were identified in the stomachs ; of these the most important were four species of dogwood, three of wild grapes, four of greenbrier, two of holly, two of elder ; and cranberries, huckleberries, blueberries, barberries, service-berries, hackberries, and per- simmons, witli four species of sumach and various seeds not strictly fruit." Six robins shot in Nebraska by Professor Aughey had eaten two hundred and sixty-five Rocky Mountain locusts and eighty-four other insects. In Wisconsin Professor King exam- ined the stomachs of thirty-seven specimens taken during the interval between March and October. '' Five birds had eaten THE THRUSHES AND THEIR ALLIES. 93 eleven cutworms ; three, five wire- worms ; two, two hairy caterpillars ; one, a hog-caterpillar of the vine ; five, eight scarabseid beetles ; two, two curculios ; one, a click-beetle ; one, an ichneumon-fly ; two, two spiders ; one, a millipede ; two, two angle-worms ; six, nine grasshoppers ; two, eight grassliopper's eggs ; one, a moth ; three (young birds), pellets of grass ; one, choke-cherries ; two, black cherries ; one, raspberries ; one, grapes ; one, sheep-berries ; and one, ber- ries of Indian turnip." A few years ago we examined the stomach contents of a robin shot in Michigan between a row of cherry-trees and a raspberry-patch, both with ripe fruit. The stomach was almost tilled with maggots, apparently belonging to some species of Anthomyia. Sixty of these larvae were present. The earliest extended investigation of the food of the robin was that made in Massachusetts about half a century ago by Professor J. W. P. Jenks. The study was continued throughout the year, and in the main the results obtained are very simi- lar to those of Forbes summarized above. Bibio larva? formed the principal food in early spring. Audubon states that in the South during winter the robins feed on the berries and fruits of the holly, sweet-gum, gall-berry, and pokeweed, as well as the caperia-berry, wild-orange berry, and the berries of the pride of India. The seeds of most of the berry-like fruits which the robin eats are not digested, and doubtless are widely scattered by the birds. In 1891 Mr. E. V. Wilcox examined the stomach contents of nearly two hundred Ohio robins, taken during April, May, June, July, and August. '' The great majority of the birds were killed on the Ohio Experiment Station grounds, a])out fifty being taken in other parts of the State." These grounds were largely devoted to the cultivation of cherries, strawber- ries, raspberries, blackberries, and other fruits. On this ac- count it would seem probable that the i)ercentage of fruit eaten would be greater than under ordinary Held conditions, but the 94 BIRDS IN THEIR RELATIONS TO MAN. fruit ratios are uniformly less than those obtained in Illinois by Professor Forbes. The results throughout are quite similar to those of the last-named investigator. The economic percent- ages are summarized as follows : Beneficial species (plants and animals), 52.4 per cent. ; injurious species, 18.6 per cent. ; neutral species, 28.9 per cent. It will be seen that these are much more unfavorable to the robin than Professor Forbes's results. The difference is largely due to the fact that the latter includes the months of February, March, and Septem- ber in addition to the months covered by Mr. Wilcox ; and also to the fact that in Illinois theBibio larvne were considered injurious, while in Ohio they were ranked as neutral. While these insects may now confine themselves to decaying organic matter, it seems, from the feeding habits of their allies, very probable that were the check the robin places upon their in- crease removed they would soon be compelled to resort to living vegetation for at least part of their diet, and become injurious. Consetiuently I think the robin entitled to credit for their destruction. The interesting point is brought out that '' during the fruit season the robins shot in the station gardens were in the proportion of nine young to one old bird, and that the old birds took much more insect food than the young. While the young birds were feeding upon raspberries and other garden fruits, the old birds might be found more abundantly on newly mown meadows or in woodlands." Similar conditions have often been noticed in other localities. To show how onmivorous a bird the robin is, Mr. Wilcox states that he found in the stomachs examined ^-caterpillars of all sorts, from the smooth geometrids, or span worms, and cutworms to the more hairy kinds, such as the walnut cater- pillar (DaUma mu/usi) and even the common brown caterpillar {Pyrrharctia imbclla). Coleoptera of several families were noted, — Staphylinidae, Dermestidae, Carabidae, Scarabaeida*, LampyridiP, Elateridoe, Otiorhynchidfe, Curculionidoe, Niti- tulidie, Clirysoiiiclida', and Buprestida?. There were found THE THRUSHES AND THEIR xVLLlES. 95 adult and pupal Hynienoptera, adult and larval Diptera, Co- leoptera, and Lepidoptcra, adult and nymphal Hetei^optera, Homoptera, and Orthoptera, adult Neuroptera (a small dragon- fly), spiders, small snails, sowbugs, and Myriapods." In ad- dition to this animal food, " a great majority of ttie fruits, cultivated and uncultivated, which have a juicy nutritious portion are included in the dietary of the robin." Concerning the fruit-eating proclivities of the robin, Mr. W. J. Green, of the Ohio Agricultural Experiment Station, writes : "The capacity of the robin for berries is enormous, and when hundreds come at once the grower suffers serious losses. On the station grounds nearly all of the early raspberries and blackberries are taken by the robins, and only in the height of the season are there enough berries left to give the pickers a chance to earn fair wages. If left to themselves the robins would take the greater share of the black raspberries that grow on a plantation of more than an acre. Growers in other parts of the country have complained of losses quite as large." The above accounts relate to the food of the adult robins. We have next to consider that of the nestlings. Properly to appreciate the importance of the latter, we must remember that as far north as Massachusetts three broods of nestlings are commonly reared ; that from early spring till late in the summer each pair of old birds is engaged at least half of the time in providing food for four, five, or six ravenous birdlings ; and that each of the latter probably requires more food while in the nest than does one of the adults during the same period. It seems to us that the chief claim of the robin upon man's favor rests upon these facts. In 1884 we examined the stomach contents of six young robins from Michigan nests. The largest single element of the food consisted of cutworms and related caterpillars, which formed twenty-seven per cent, of the total dietary. Among other insects present were seven per cent, of beetles, includ- 96 BIRDS IN THEIR RELATIONS TO MAN. ing curculios and ground-beetles, and various undetermined species. There Avere also present twenty per cent, of earth- worms, one per cent, of snails, three per cent, of myriapods, and about thirty per cent, of grass blades. The latter seem almost always to be found in the stomachs of nestling robins ; they may be introduced accidentally with the cutworms or possibly may have a dietetic value. The food of fourteen nestlings examined by Beat consisted of caterpillars, locusts, grasshoppers, crickets, and beetles, with a few spiders, snails, and earthworms, and seven per cent, of berries of various kinds. Professor King found the stomachs of three Wisconsin nestlings to contain wire-worms, white grubs, caterpillars, beetles, small seeds, and grass. Dr. T. M. Brewer watched the feeding of a set of young robins near his house, "and, so far as they were seen, the nestlings were fed until they left their nest entirely with the moths of the family Agrotiidae or subterranean caterpillars, commonly known as cutworms." We suspect he meant to write the larvae of the moths, instead of the moths themselves, although it is known that the latter are sometimes fed to the young. In his admirable account of the nesting habits of the robin, ^ Professor Herrick states that the young are fed with grasshop- pers, crickets, katydids, and angle-worms, as Avell as such fruits as choke-cherries, blueberries, and raspberries. Evidently for the nestlings, as for themselves, robins take the kind of food that is most abundant. Years ago Wilson Flagg watched a pair nesting near his house. They were rearing " a second brood in the month of July, when the soil was so greatly parched by drought that if robins lived only on berries and earthworms they must have starved to death. I had often seen the birds at a distance pecking vigorously upon the sward and then drawing out a worm. I knew that there w^ere at this time no ' Home Life of Wild Birds, chap. iv. Tin: TIIKUSHKS AND THEIK ALLIES. !)7 earthworms iirar enough tho surface to be witliiii the reach even of the loiig-biUed snipes. But when the bird was near enough I could distinctly see, by the form and appendages of the creature, that it was invariably a cutworm of a large species and of an olive-green color. The female bird was most industrious. She would carry off one of these grubs as often as once in five minutes, whenever I watched her movements, and very often she would have two in her bill at a time. One day close under my window, I saw her bear off three cut- worms at once, all of which were taken before my sight in a space about a rod square." The robin appears to be one of the birds that thrives fully as well under the conditions of modern agriculture as when the soil was owned by the red man. A knowledge of its feed- ing habits would lead one to expect this. In many localities it is believed that these birds are now more numerous than in earlier times. On the whole, there can be no doubt that it is an eminently useful bird, but it is equally certain that too often the fruit-grower alone has to pay heavily for services rendered to the community at large. In concluding his dis- cussion of an elaborate investigation of the food of adult robins, Professor Forbes expresses his belief that tlie horti- culturist cannot " sell his small fruits anywhere in the ordi- nary markets of the world at so high a price as to the robin, provided he uses proper diligence that the little huckster does not overreach him in the bargain." If this is true when the food of the adult alone is considered, it is much more so when the food of the nestlings is also taken into account. Nevertheless, we believe the fruit-grower sliould be allowed to protect his crops when necessary, doing so in such a way as to accomplish the greatest results with the least expen- diture of robin life. But the indiscriminate destruction of the birds for food, '-sport," or millinery purposes should be stopped, and the robbing of the nests should be properly punished. 98 BIRDS IN THEIR RELATIONS TO MAN. THE CAT-BIRD. While the cat-bird in most locaUties is much less abundant than the robin, it is almost as well known. It is a shyer species, commonly haunting shrubbery and underbrush in clearings and along running streams. It is a migrant and rarely winters very far north. The food of seventy Illinois specimens, shot during May, June, July, August, and Septem- ber, was studied by Professor Forbes. Insects formed eighty- three per cent, of the food of twenty-two May examples : the remainder consisted of spiders, myriapods, and sumach- berries. " Among the insects were about equal ratios of ants, crane-flies, and beetles, the first composing eighteen per cent, of the food, the second nineteen, and the third twenty-three. Caterpillars formed twelve per cent, of the food, and about one-sixth of these were distinctly recognizable as cutworms. More than one-third of the beetles were Carabidae, including specimens of Platynus and Harpahis penmylvanicus.^^ Four per cent, of Orthoptera were present, there being specimens of the snowy tree-cricket, grasshoppers, and young walking- sticks. " During the first part of June large numbers of ants and crane-flies were again eaten. Many May-beetles were also taken. During the last half of the month these insects were largely replaced by cherries, currants, raspberries, and strawberries." Three-fourths of the food of eleven July cat- birds consisted of small fruits, mostly (sixty-four per cent.) blackberries. Nine per cent, of beetles had been taken, most of them being predaceous. '' It is clear that the cat-bird in midsummer eats only such insects as come in its way while regaling itself on the smaller fruits." " The food-record of August resembles that of June, owing doubtless to the diminution of the smaller garden fruits at this time and to the fact that the wild fruits have not yet come into bearing. The insect percentages are therefore much larger than in July, and it is instructive to notice that THE THRUSHES AND THEIR ALLIES. 99 this increase is first apparent and most evident in the ratios of ants, an indication of the positive preference of the cat- bird for this food. Nearly one-half of the forty-six per cent, of insects eaten this month were ants.'' Among the beetles eaten was one striped cucumber-beetle, and among the bugs were a few chinch-bugs. Blackberries formed the staple fruit element. During the first half of September cherries, wild fruits, and grapes formed seventy-six per cent, of the food. The fmal percentages of the food for the five months are : beneficial, forty-one ; injurious, fifteen ; neutral, forty-four. Five cat-birds examined in Nebraska by Aughey had eaten one hundred and fifty-two Rocky Mountain locusts. Twenty- five specimens shot during May in the IlHnois orchard where canker-worms were at work, and studied by Professor Forbes, had eaten fifteen per cent, of canker-worms. This author also reports having seen cat-birds " busily scooping out the fairest side of the ripest early apples, unsurpassed in skill and industry at this employment by the red-headed woodpecker or the blue-jay." Evidently there is room for improvement in the economic status of the adult cat-bird. But the dietary sins of the parents are largely atoned for by the food of the young. In 1884 we examined the stomach contents of three Michigan nestlings of this species : ninety-five per cent, of the food con- sisted of insects ; two per cent, of spiders ; and three per cent, of Myriapods. Sixty-two per cent, of the food con- sisted of cutworms ; eleven per cent, of ground-beetles ; four per cent, of grasshoppers ; three per cent, of May-flies, and two per cent, of dragon-flies. The large proportion of cut- worms strongly favors the usefulness of the species. Pro- fessor Herrick's observations ^ show that dragon-flies, caught just as they emerge from the nymph state, are commonly fed the nestlings, as are also '• insect larvae, beetles, moths, millers, ^ Home Life of Wild Birds, chap. viii. 100 BIRDS IN THEIR RELATIONS TO MAN. and a great variety of smaller insects, varied with liberal courses of strawberries." Fourteen nestlings studied by Judd had eaten but four per cent, of fruit, their diet being chiefly ants, beetles, caterpillars, spiders, and grasshoppers. While the cat-bird by no means deserves the cruel and senseless persecution it too often receives, it seems to us that the fruit-grower should be allowed to protect himself from ruinous injury by it. We have no doubt that, on the whole, the benefit Avhich it does is much greater than the harm, and its destruction should never be permitted except when necessary to save precious crops. Professor F. E. L. Beal be- lieves that " cultivated fruits can be protected from the cat-bird by the simple expedient of planting wild species or others which are preferred by the birds." Dr. Judd has shown that Russian mulberries are preferred to cherries by these birds. OTUEll THHUSHES. Every farmer's boy in the Middle States has heard the song of the Brown Thrush or Thrasher. In many respects its vocal powers excel those of any of the northern birds that are known by every body. It is a shy creature, haunting shrub- bery and underbrusli and skulking away on the approach of man. When scratching the dry leaves or running over the surface of the ground, the rustling noise it makes is sur- prising : in the palmetto brush of southern Florida we have often been led to think some larger animal was present. It is a regular migrant, breeding in the north and wintering south. We are indebted to Professor Forbes for quite a full knowl- edge of the food of the brown thrush. Two separate inves- tigations were made, the first including twenty-eight birds shot in Illinois during April, May, June, and July, and the second sixty-four specimens covering the six months from April to September. The feeding habits for this time are thus recapitulated. "The brown thrush, arriving in April, linds nearly one- THE THRUSHK AXn TIIKIli ALLIK 101 half of its food in fragments of corn and other grains and seeds picked from the droppings of animals. This curious habit it maintains throughout the year, evidently taking this food from preference as well as from necessity. In fact, I have often found these vegetable fragments associated with black- berries in the food. After April this element averages about sixteen per cent, throughout the season. Insects amount to about half the food for each month, except in May, when %f"^^W^ ' W" / X/ THE BROWN THRUSH. {After Biological Siirve?j.) they rise to three-fourths, and in July, when they drop to one-fourth. The excess in May occurs at the time of the greatest number and activity of the beetles, and the diminu- tion in July coincides with the period of the greatest abun- dance of the small fruits. One-half the hisects eaten are beetles, wliich stand at one-fourth of tlie food in April and June, rise to one-half in May, and fall to about one-eighth in July and August. Half the beetles of the year are Scara- bseidiB, chiefly June-beetles and Euryoma, all taken previous to July. Nearly oiic-rourth of llic beetles are Carabid^, which remain at al)()ut fivt? per cent, of the food, except in May, when they rise to ten per cent. Although the ratios 102 BIRDS IN THEIR RELATIONS TO MAN. of spring-beetles and snoiit-beetles are but two per cent., the numbers eaten are of some significance. My notes show that these birds were eating each at the daily rate of one and one- half curculios, and consequently had averaged a total of about two hundred and fifty to each thrush for the season. The brown thrush takes ants more freely than the robin, but e-ats comparatively few caterpillars ; seven per cent, of each were found in the food of the year.

( After Rilpif. ) This bird eats thousand-legs mere freely than the robin, espe- cially in early spring. In the garden it plays a part very similar to that of the other thrushes, but is less mischievous, on the whole. Its average of the edible fruits for June, July, and August is thirty-eight per cent., as against sixty per cent, of the robin and forty-nine per cent, of the cat-bird. It relishes the whole list of garden fruits, and later in the season resorts to the wild fruits of the woods and thickets.'' THE THRUSHES AND THEIR ALLIES. 103 The nestlings of this species are fed upon spiders and insects, especially the various grasshoppers and caterpillars. The famous Mocking-bird, whose music is to Americans much what that of the nightingale is to Europeans, is com- monly found in the Southern States. As a rule, it is rare north of latitude 40. Its food appears to be much like that of the other thrushes, consisting of about equal proportions of insects and various wild and cultivated fruits. The young appear to be fed chiefly upon insects, among which the moth of the cotton-boll-worm deserves special mention. In the North the Wood-Thrush is the most famous songster of its family. It is common, but not abundant, in most of the Eastern States, north to New England. It is usually a shy bird, haunting woodland shrubbery, but there are indications that it is becoming more familiar with man, and there seems good reason for hoping that in time it will be much more com- monly seen upon the home grounds. Professor Forbes's studies of the food of twenty-two Illinois birds show that it is one of the most useful of the thrushes, eating large numbers of injurious insects and comparatively little fruit. One speci- men had stuffed itself with rose-beetles [Macrodactylus sub- sp'niosus) and others had eaten large numbers of ants and crane-flies. Insects as a whole formed seventy-one per cent, of the food. Of course every one is eager to encourage the advances of this beautiful songster. The economic relations of the other thrushes — such as the Hermit, Alice, or Swainson's — appear to be very similar to those of the wood-thrush. The hermit is credited — or rather debited — with the destruction of many predaceous beetles during its northward migration, and the other two species mentioned are unusually fond of ants and caterpillars. In summarizing the food of the family of thrushes as it occurs ill Illinois, Professor Forlx'S says: "Sixty-one per cent, of the food consists of insects, one i)er cent, of spiders, two per cent, of Alyriapods, and thirty-two i)er cent, of fruits, 104 BIRDS IN THEIR RELATIONS TO MAN. eleven per cent, being blackberries, eight per cent, cherries, one per cent, currants, and five per cent, grapes. Thirty parts of the food consist of injurious insects and eight parts of beneficial species, while twenty-six parts consist of edible fruits." This, however, refers only to the adult birds, the food of the young not being sufficiently known to be included in the estimate. All the observations on record indicate that the nestlings of thrushes are fed upon insects, especially smooth caterpillars like the cutworms, so that there is little doubt that this factor would largely increase the already con- clusive evidence as to the great value of this splendid family. The charming little kinglets of the family ISylvUdw are among the most deUghtful of the pygmy birds. They frequent the tops of tall trees so constantly that they are seldom seen by most people. Two species are rather common in our Nortliern States, the Golden-crowxkd and the Ruby-croWx\ed Kinglets. Both are insectivorous in llicir feeding habits. i; <.i ii.iii;n I Kdw N i:i( k i CHAPTER IX. THE NUTHATCHES, TITMICE, CKEEl'EHS, AM) WHE.XS. THE NUTHATCHES. The nuthatches [Sittiuce) comprise a small group of creeping birds which inhabit woodlands cliiefly, although they often visit trees in orchards and groves or along the highway. Most of their food consists of insects gathered from the bark of trees, but part of it is composed of seeds of various kinds. They are compact flattened birds, with plumage of modest colors and hard barbed and pointed tongues. Four species and one variety occur in the United States, a common form in the Northeast being the White-breasted Nuthatch, which in the Middle and Western States is replaced by a variety with a more slender bill. This bird is frequently abundant in wood- lands, and moves actively about over trunks and branches in search of food. Professor King examined tlie stomach con- tents of twenty-five Wisconsin specimens, and found that fourteen of them had eaten beetles, including elaters and longicorns, while others contained ants, caterpillars, and beetle- grubs, a spider and a chrysalis, a few small toadstools, some acorns, and a little corn. Four Illinois specimens had eaten beetles of various kinds, some of them being lady-beetles. The food of this species in winter and spring was made the subject of a s[)ecial study by Pro lessor E. D. San- derson. '-During the winter tlic larger pi'oportion of the food was composed of seeds, which gradually decreased as insect life became more abundant.'' Seeds of Indian corn, ragweed, and wild sunflowers were recognized ; the insects were largely in eg^^ or larval stages. In spring nearly eighty per cent, of the food consisted of insects, cliii^fly adults. No traces of acorns were nnnid in Hm- slKiiiaciis cxaniinccl. From 106 BIRDS IN THEIR RELATIONS TO MAN. these studies Professor Sanderson reaches the conclusion that this species is " either absolutely neutral or of comparatively small economic importance," — a conclusion which, it seems to us, is by no means warranted by his results. During the spring, he writes, " Hymenoptera were found in considerable numbers, all being beneficial.'^ Probably it is on this account that the usefulness of the birds is doubted. But we believe, as indicated in Chapter VI., that investigators err in saying that all parasitic insects are beneficial. The nest of this bird is built in a hole in a tree, tlie cavity being sometimes excavated by the nuthatch and sometimes by another bird or a falling limb. The rapid destruction of forests and the thinning out of dead trees in orchards and woodlands must reduce tlie available nesting sites and thus tend to lessen the numbers of the nuthatches. There is some reason for supposing that if suitable artificial nesting places were provided in orchards these birds would breed in them. It is an experiment well Avorth trying. The Red-hheasted or Canada Nuthatch is much rarer than the last-named species in many parts of the United States, although the two birds seem to be very similar in their feed- ing habits. It breeds in holes and stumps, and feeds on beetles, ants, and other small insects. In Nebraska it has been seen eating young grassho})pers. THE TITMICE. The titmice, or chickadees, which with the nuthatches and wren-tits form the family ParidtB, are represented in North America by nearly a score of species and varieties, the great majority of which, howevin*, are rare or only locally distrib- uted. The common Chickadee, or Black-capped Titmouse, is much the most familiar species in the Eastern States, remain- ing with IIS lliroiigliout the year. It takes a great variety of food, gleaning through the winter h'oiii th(^ bai'k and twigs of both deciduous and evergreen trees, and in summer NUTHATCHES, TITMICE, CREEPERS, AND WRENS. 107 dovouriiii,'- iiisccls of many kinds. In a canker-worm infested orchard sixty-one per cent, of the food of two cliickadees con- sisti^d of these caterpillars, while injurious beetles constituted the remainder. In a recent investii^ation of the winter food of the chick- adee, we studied ^ the stomach contents of forty-one speci- mens taken during November, December, January, February, and March. The results as a whole show that more than half of the food of the chick- adees during winter consists of insects, a very large pro- portion of wiiich are taken in the form of eggs. About five per cent, of the stomach contents consisted of spiders or their eggs. Vegetation of various sorts made up a little less than a c{uarter of the food, two-thirds of which, however, consisted of buds and bud-scales that were be- lieved to have been accidentally introduced with plant-lice eggs. These eggs made up more than one-fifth of the entire food and formed the most remarkable element of the bill of fare. This destruction of the myriads of eggs of plant- lice which infest the fruit, shade, and forest trees is probably the most important service the chickadee renders during its winter residence. More than four hundred and fifty eggs sometimes occur as the food of one bird in a single day. On the supposition that one hundred were eaten daily by each of a flock of ten chickadees, there w^ould be destroyed one thousand a day, or one hundred thousand during the davs of winl(^r, a number whicli we believe to b(^ far below THE CHICKADEE. OR BLACK-CAPPED TITMOUSE. * New Hamp?hirp College Agriniltiiral Exporimont Station, Bull. o4. 108 BIRDS IN THEIR RELATIONS TO MAN. ' the actual average, could Ave determine it precisely. Insects' eggs of many other kinds were found in the food of the chick- adee ; many of these it was impossible to recognize, but there was no difficulty in identifying tlie eggs of the common Ameri- can tent caterpillar and of the fall canker-worm, the eggs of Avhich remain upon the trees through the winter. There were also present the eggs and egg-sacs of many spiders of kinds commonly occurring under loose bark. While spiders as a class are doubtless beneficial creatures, the destruction of some of them is not in our opinion seriously detrimental to th(^ usefulness of the cliickadee. The larva^ of several differ- ent kinds of moths were also found. One of the most abun- dant species was believed to be tli<' common apple-worm, the larvae of the codling moth. The bark-beetles of the family Scolytidae, which are destructive to forests all over our coun- try, were also freely eaten by the chickadees. The hairy skins of the fruits of the common wild sumachs were among the most abundant elements of the vegetable food present. The edible j)orli()n of these fruits is evidently eaten to a con- siderable extent throughout the winter and early spring. An- other common element of the food appears to consist of the curious little fruits of the bayberry or waxberry myrtle — an abundant shrub along tlie sea-coast. In winter chickadees have been observed to hide away surplus food, to eat at a later time. A careful study of the food of the chickadee in Michigan has also been made by Professor E. D. Sanderson, with re- sults very similar to those recorded above. As an indication of the usefulness of these birds, he writes: ''If fifty-tive in- sects were consumed i)er day by each l)ird, as will be shown to be the case, three hundred and <'ighty-five would be con- sumed per day by a ilock of seven, which is believed to be a lair average for each sc|uare mile: this would be about one hundred and tliirty-seven thousand five hundred per year in each square mile. Thus upon the land surface of Michigan NUTHATCHES, TITMICE, CREEPERS, AND WRENS. 109 there will annually be about eight thousand million insects destroyed by chickadees alone. Surely no mean number." The closely related Long-tailed Chickadee of the Western States feeds largely upon grasshoppers when the latter are abundant. The Carolina Titmouse of the Southern States appears to have food-habits similar to those of its northern representative, except that through the winter months it doubtless finds a larger percentage of insect food. THE creepers. The small family of creepers {Certhiidce), of wliicli only about a dozen species are known in the entire world, has ])at one representative in the United States. These birds in outward appearance and habits are suggestive of the wood- peckers. They have rigid tail-feathers and a slender de- curved bill, with toes adapted to running up the sides of trees. The Brown Creeper is the common American representa- tive of this family. It is a small bird, very restless and active, which may often be seen by bird-lovers going in spirals up tree trunks, but never hanging head downward like the nut- hatches. It nests behind loose bark on the trunks of trees, and in most of the Northern States may be found through- out the year. Very few precise determinations of its food have been made : three stomachs examined by King contained small beetles and other insects, and Nelson reports that he has seen several of these creepers on the sides of a house searching for spiders. In June, 1895, Aughey saw two parent birds bring to a nest of young twenty-seven locusts in an hour. In Maryland, Judd found that one bird had eaten beetles, sawflies, flying ants, spiders, and seeds of the scrub pine. There can be no doubt that this is a very useful little bird, deserving all possible encouragement. 110 BIRDS IN THEIR RELATIONS TO MAN. THE WRENS. The elegant little wrens, in their suits of brown and drab, belong to a small family {Troglodyt'uke) of highly insectivo- rous birds. The saucy House-Wren is much the most familiar representative. It occurs throughout the United States, from the Atlantic to the Pacific, the western being considered a ^^^^"^fe. THE HorSE-WKEN. {Afia- nioUnjicnl Siirreij.) distinct geographical race. In the Northern States it is migra- tory, spending the winter in the South. It nests about barns and dwellings in almost any situation, and is easily encour- aged by putting up nesting-boxes. The house-wren is a very useful bird to have searching constantly for insects in the shrubbery of the ornamental grounds, the trees of the orchard, or the vines of the garden. Its diet appears to be exclusively insectivorous ; including on its bill of fare larv;e and caterpil- lars of many kinds, as well as ants, grasshoppers, gnats, bee- tles, bugs, spiders, and myriapods. Professor Augliey repeat- NUTHATCHES, TITMICE, CKEEIM':ilS, AM) WKEXS. lH 0(11 y observcHl both this and olhcr whmis carrying youiiLj locusts to llicir nestlings. Nearly lialC llic food of several specimens shot in an orcliard infested by canker-worms con- sisted of these pests. Fifty-two stomachs were examined at the United States Department of Agriculture, the record show- ing '' that ninety-eight per cent, of the stomach contents was made up of insects or their allies, and only two per cent, was vegetable, including bits of grass and similar matter, evidently taken by accident with the insects. Half of their food con- sisted of grasshoppers and beetles ; the remainder, of cater- pillars, bugs, and spiders." The house- wren is accused,^ apparently on good evidence, of sometimes pecking holes in the eggs of chipping-sparrows and throwing them out of the nest. Probably this is a special habit of certain birds, due to unusual conditions, although it may well lead bird-lovers to watch the wrens to see how general it is. A mother wren observed by Judd made one hundred and ten visits to her nest in feeding her young in four hours and thirty-seven minutes, feeding them one hundred and eleven insects and spiders. Two species of Marsh-Wrens are common in the United States, the long-billed and the short-billed. They especially haunt swampy ground, the former building an enormous glob- ular nest among the reeds. Both species feed upon insects, spiders, and snails. Of fourteen Wisconsin specimens of the long-billed marsh-wren, one had eaten " one ant ; one, a cat- erpillar ; one, three beetles ; three, three moths ; one, a small grasshopper; one, five grasshoppers' eggs; one, a dragon-fly; and one, a small snail." (King.) Five Maryland si)ecimens had eaten spiders, beetles, bugs, leaf-hoppers, flies, four-wingcnl parasites, and ants, the first two forming the major portion of the food. * Bird Lore, ii. 90. CHAPTER X. THE WARBLERS AND THE VIREOS. THE WOOD WARBLERS, OR AMERICAN WARBLERS. The beautiful-plumaged American warblers (3IniotiIticke) form next to the largest family of our native birds. Nearly all of them are small. As a group they are abundant and widely distributed, migratory, and insectivorous. In many species the plumage varies greatly with the age and sex. There are about sixty North American representatives of the family. "With tireless industry do the warblers befriend the human race," writes Dr. Elliott Cones; "their unconscious zeal plays due part in the nice adjustment of nature's forces, helping to bring about that balance of vegetable and insect life without which agriculture would be in vain. They visit the orchard when the apple and pear, the peach, plum, and cherry are in bloom, seeming to revel carelessly amid the sweet-scented and delicately tinted blossoms, but never faltering in their good work. They peer into the crevices of the bark, scruti- nize each leaf, and explore the very heart of the buds to detect, drag forth, and destroy these tiny creatures, singly in- signiticant, collectively a scourge, which prey upon the hopes of the fruit-grower, and which if undisturbed would bring his care to naught. Sojiie warblers flit incessantly in the terminal foliage of the tallest trees ; others hug close to the scored trunks and gnarled boughs of tlie forest kings ; some peep from the thicket, llie -coppice, the impenetrable mantle of shrubbery tliat decks liny water-courses, playing at hide and seek with all comers; otiiei's, morc^ humble still, descend to the ground, when^ they glide, with i)retty, mincing ste})s and affected turning of the head this way and that, their delicate 112 THE WARBLERS AM) THE VIREOS. 113 flesh-tinted feet just stirring- tlie layer of witluTcd leaves with which a past season carpeted the ground."' The Black and AVhite Creeping Warbler, sometimes called the black and white creeper, is abundant in most wooded portions of eastern America, extending westward to Dakota and Nebraska. It resembles the creepers and nuthatches in its manner of taking food, searching every cranny and crevice of the bark of trees for the insects sheltered there, occasion- ally chasing for short distances moths or other creatures frightened from their hiding-places ; and sometimes scruti- nizing the foliage, like other warblers. The nest is placed on or near the ground, very often on a rocky ledge. Four or five young are reared. The insects eaten by the bird belong mostly to species of small size. Seventeen Wisconsin specimens had eaten five ants, twenty small measuring worms and one other caterpillar, four moths, five two-winged flies, one curculio and fifteen other beetles, seven bugs, a caddis-fly, and a small snail, besides more than a hundred insects' eggs. One Nebraska bird had swallowed forty-one locusts and twelve other insects, together with a few seeds. The Blue Yellow-backed Warbler is a beautiful little bird which spends much of its feeding time among the topmost twigs of the tallest trees. It is common in eastern America and is found as far west as the Rocky Mountains. In New England it has been observed feeding on May-flies, measuring worms, and spiders ; in Wisconsin six small insects were taken from a single stomach, and in Nebraska it has frequently been seen picking up locusts and other insects. A picture of it is shown in the frontispiece of this book. The Nashville Warbler is found, occasionally at least, throughout almost the whole of North America, specimens of it having been taken as far noi-lh as (Irecnlaiid, as far wrsi as Utah, Nevada, and California, and as far south as M(\\ico. Its chief distribution, however, is in Mie region east of the 8 114 BIRDS IN THEIR RELATIONS TO MAN. Mississippi River, where il is a regular uiigrant, breeding as far s(3uth as tlic northern counties of Illinois and the central portion of New England. The nest is placed on the ground. The only food records that we have show that two Wisconsin spociniens had eaten four small green caterpillars and some other insects not identifiable, and that one Nebraska fledgling had devoured twenty-one locusts and several other insects, while the adult birds have frequently been seen feeding on locusts. The Tennessee Warbler is a very interesting migratory species that passes regularly and abundantly through the Mis- sissippi Valley States during its spring and autumn migrations. It also occurs sparingly west to the Rocky Mountains and east to the Atlantic Ocean. It breeds in the far North and winters, in part at least, in South America. It searches diligently for the insect mites that infest the foliage of trees, seeming to have a special fondness for aphides, forty-two of which have been taken from the stomachs of three of these birds. Among the other food elements of thirty-two specimens there were found two small Hymenoptera, thirteen caterpillars, fifteen two-winged flies, thirteen beetles, thirty-five small bugs, and eleven insects' eggs. Four-fifths of the food of one bird shot in an orchard infested by canker-worms consisted of these pests. Teiniessee warblers have also been seen feeding on small grasshoppers. This, however, is one of the very few warblers against which a charge has been brought by the fruit-growers. In some sections it is known as the "grape-sucker," because it l)mi(tures ripe grapes with its little beak, presumably to get at tiie juice. Testimony on this point appears to be conclusive, and considerable injury occasionally results. There can be no doubt, however, that in the aggregate the bird does vastly more good than harm. Tlie Yellow-rumped Warbler, or Myrtle-Bird, is an ex- ceedingly hardy little creature, often enduring the rigors of a THE WARBLERS AND THE VIREOS. 115 New England winter when its congeners are basking in the sunshine of the South. It is distributed over a large North American range, and is abundant in all sorts of situations, especially during the spring and autunui migrations. It breeds regularly in the far North, commonly nesting, liow- ever, in the northern tier of States and in southern ('anada. According to Ridgway, it is a connnon Avinter resident in southern Illinois. Of twenty-one specimens studied by King, " one had eaten a moth ; two, twenty-one caterpillars, mostly measuring worms ; five, fourteen two-winged flies, among which were three crane-flies ; fifteen, forty-eight beetles ; one, four ichneumon-flies ; one, a caddis-fly ; and one, a spider." Our own studies ^ of many specimens show that in autumn three-fifths of its food consists of myrtle-berries, the remainder being largely insects, while in spring tlie insect ratios are much greater. The Yellow Warbler, or Summer Yellow-Bird, is probably the best-known member of its family. It seems perfectly at home throughout the whole of North America, from the trop- ical regions of the South to the"arctic lands of the North. It is a familiar and confiding bird, associating freely with civilized man, and building its neat nest of vegetable fibre in the trees of the orchard, park, family residence, and public thorough- fare. Three or four eggs are usually deposited in the nest, and when an additional one is left by a skulking cow-bird, the warblers — with a wisdom beyond their size — sometimes add another story to the nest and begin again their domestic duties, leaving the stranger egg and if necessary some of their own to go unhatched. The food habits of the yellow warbler are all that could be desired. It freely visits farm premises and feeds on minute insects of many kinds. Two-thirds of the food of five Illinois > Dearborn and W.-.-d. Tech. l^illcliii Xo. ,'!, X. H. C. Exp. St., VinA of the Mvrtle-Wiiil.ltT. 116 BIRDS IN THEIR RELATIONS TO MAN. specimens consisted of canker-worms, and most of the re- mainder was an injurious beetle. An equal number of Wis- consin birds contained small caterpillars and beetles ; and from various other specimens spiders, myriapods, moths, bugs, flies, grasshoppers, and other insects have been taken. The Black-throated Green Warbler, which is especially characterized by its jet-black chin, throat, and breast, is abundant in New England and extends westward to Ne- THE MAGNOLIA WARBLER. braska, breeding in pine trees throughout tlie northern por- tion of its range. Its food is obtained among the branches of tall trees, largely while upon the wing, and consists of a great variety of small insects, including caterpillars and larv« of many kinds, curculios and other beetles, small bugs, and various Hymenoptera. An idea of the number of insects it THE WAHBLEKS AND THE VHiEUS. 117 consumes may be obtained from the statement tliat the stomachs of five birds taken in Nebraska during June con- tained one liundred and sixteen small locusts and one hun- dred and four other insects, an average of forty-four to each bird. Seventy per cent, of the food of one Illinois specimen consisted of canker-worms. The beautiful American Redstart is a much commoner species in most of the Northern States than would be sup- posed by those who have paid no special attention to the study of birds. Living amidst the foliage of trees, it is seldom seen except by those looking for the warblers found in such situations. The redstart is '• the flycatcher of the inner tree- tops,'" capturing on the wing the numerous insects that flit about among the branches and occasionally taking a cater- pillar hanging by a thread or crawling on a twig. The food of the few specimens that have been critically examined con- sisted of small two-winged flies, a few parasitic Hymenoptera, an occasional small bug. and some minute larvae. Seven Nebraska specimens had eaten one hundred and sixty-one small locusts and one hundred and seventeen other insects. The young are fed with moths and other insects caught when upon the wing. The handsome little Maryland Yellow-throat, in its typical form or that of a subspecies, is found throughout the United States, from the Atlantic to tlie Pacific oceans, and in many localities is one of the most abundant of the warblers. It especially frequents the shrubbery about standing or running water, where it can be found throughout tln^ summer busil\ searching for insect food. It often visits orchards, where canker- worius and other caterpillars are greedily devoured, these fornung in three cases on record four-fifths of its food. The little case-bearing cateri)illars of the genus Coleophora and its allies are often eaten, while butterfiies, moths, two-winged Hies, beetles, grasshopi)ers, leaf-hoppers, bugs, dragon-flies, Hymenoptera, and insects' eggs are all included on the bill of lis BIRDS L\ THEIR RELATIONS TO MAN. fore. 'Jlie young are sometimes fed with small grasshoppers, and these insects are a favorite item of food with the adult birds. Like the yellow warbler, this species sometimes outwits the cow-bird by its intelligence. Mr. A. W. Butler thus describes the three-storied nest of a yellow-throat in his possession : " In the original nest had been deposited the egg of a cow- 5UTTERFLY CAUGHT BY MARYLAND YK bird, tlicii williiii tlial nest and rising above it the yellow-throat had built anotlier nest, which also became the depository of the liope of offspring of this unnatural bird ; again the little warbler constructed a third n(^st ui)on the other two, burying the cow-bird's egg, and in this nest laid her complement of eggs." These examples will suffice to make manifest the fact that the warbler family is one of extraordinary economic value, the members of which are immensely useful in checking noxious insects and with very few exceptions have no injurious habits. It is particularly gratifying that these charming birds, whose song and plumage draw to them the good will of all intelli- gent people, should show so well that utility and beauty are not always dissociated. rhotoijruphid from Uh h,/ l>r. /.'.

They are small birds, jnodest in manners and dress, very different from the shrikes, to which. the ornithologists state that they are closely related. This is exclusively a New World family, composed of half a dozen genera and a little over half a hundred spe- cies : only one of the former, the genus Vireo, and thirteen of the latter occur in the United States. Of these thirteen species about half are common over a considerable area. In color our forms are mostly greenish olive or gray above and white or yellow below. They build slightly pendent nests in trees, migrate southward in autumn, and are almost exclu- sively insectivorous. They are more often heard than seen. '' Clad in simple tints that harmonize with the verdure," writes Dr. Coues, "these gentle songsters warble their lays unseen, while the foliage itself seems stirred to music. In the quaint and curious ditty of the white-eye, in the earnest, voluble strains of the red-eye, in the tender secret that the warbling vireo confides in whispers to the passing breeze, he is insensible who does not hear the echo of thoughts he never clothes in words." The Red-eyed VmEO seems to be the most abundant and widely distributed species of the genus. It is found in all the States except those of the extreme West, and in summer sometimes migrates as far north as Greenland. It prefers woodlands to the cultivated fields, but frequently finds its way to parks and orchards. It connnonly seeks its food among the foliage and branches of trees and shrubs, some- times chasing moths and other Hying insects for short dis- tances on the wing. It is universally recognized as a great in- sect-eater. An excellent idea of ils food may be obtained from Professor King's studies of lilty-four Wisc(^nsin specimens: "From the stomachs of eigiileen of this species were taken 120 BIRDS IN THEIR RELATIONS TO MAN. fifteen caterpillars ; five other larvae ; eight beetles, among them five weevils and one long-horn ; seventy heteropterous insects, among them sixty-seven chinch-bugs ; sixteen winged ants ; one ichneumon (?) ; five dragon-flies ; two dipterous insects, one of them a large horse-fly (Tabanus atratus); three small moths ; two grasshoppers ; one aphis ; one chrysalid ; two spiders ; and seven dogwood-berries. Of thirty-six other specimens examined, fifteen had eaten caterpillars; two, other larv}« ; nine, beetles, among them two lady-bird beetles ; three, grasshoppers ; two, ants ; two, moths ; four, unidentified insects ; and seven, fruits or seeds, among which were rasp- berries, dogwood-berries, berries of prickly ash, and sheep- berries.'' During locust outbreaks in Nebraska four-fifths of the food of this vireo has been found to consist of these insects. Of his studies of the food of the young of this species, Professor Herrick writes : '' Grasshoppers, katydids, green larvae, beetles, and bugs of many kinds were served again and again ; l)ut it would be a mistake to suppose that there was no fruit to vary tliis diet. Upon the third day the mother brought a ripe red raspberry, its juice fairly stream- ing down her bill, and after a few beetles had been taken she appeared with a large blackberry. Fruit was served to the young about half a dozen times in the course of four hours during which watch was kept on this particular day, but I had not seen a single berry brought to the young before this time.'' Professor Beat found that nestlings tliree days old had been fed with spiders, sphinx caterpillars, butterflies, assassin-bugs, and tree-hoppers. The Warbling Vireo frequents cultivated fields, orchards, and the vicinity of houses, as well as the wilder woodlands. It is an abundant species in most States and is highly insec- tivorous. Its food consists chiefly of caterpillars, including such destructive species as the canker-worm, beetles of A^arious kinds, among them the twelve-spotted cucumber- beetle and occasionallv a ladv-bird, crane-flies and other THE WARBLERS AND THE VIREOS. 121 two-winged flies, grasshoppers, bugs, and sometimes dog- wood-berries. The young are known sometimes to be fed with grasshoppers. Canker-worms formed forty-four per cent, of the food of three specimens shot in an orchard infested by these pests. The Yellow-throated Vireo is a larger bird than either of those above mentioned. It is common in tlie eastern regions of North America, and feeds on caterpillars, including meas- uring worms, moths, Aveevils and other beetles, grasshoppers, leaf-hoppers, and various flies. It evidently is a highly bene- ficial bird. The White-eyed VmEO is abundant in the Eastern States as far north as Massachusetts, and is occasionally found as far west as the base of the Rocky Mountains. It usually haunts clearings where there is much underbrush. Dr. Brewer reports that it feeds on canker-worms, and De Kay says it eats insects and berries. No precise records of the examina- tion of the stomach contents appear to have been published, but its diet is probably similar to that of the other species of the genus. Judd summarizes ^ the food of ten specimens of this species along with that of fifteen specimens of other species. Ninety-one per cent, of the food of the twenty-five vireos consisted of insects and nine per cent, of the fruit of mulberries and sassafras. 1 Birds of a Maryland Farm, U. S. Biol.

It is difficult to arrive at a satisfactory conclusion concern- ing the economic status of our Nortti American shrikes {Lanl- idce), of which there are two well-defined species, the great northern shrike and the loggerliead shrike. They are birds of extraordinary habits and feed upon an unusual variety of animal life. On the one hand it is clear that they devour large numbers of injurious insects, birds, and mice, and on the other hand that they destroy many beneficial birds. The balance of evidence, however, seems to show that on the whole the shrikes are of economic value. The complexity of the problem is increased by their peculiar habit of impaling many of their victims upon thorns, often leaving them there indefinitely. Many explanations of the origin of this habit have been sug- gested. The most plausible one seems to be that the victims are thus spitted for convenience in tearing up preparatory to eating, Dr. Judd having shown that this is necessary on account of the comparative weakness of the shrike's feet as grasping organs. The Great Northern Shrike is a bold and fearless bird. " Appropriating to himself sufficient territory, where no other bird may safely intrude, he becomes the terror of the neigh- borhood, and woe to the unlucky finch or warbler that ven- tures to trespass on these hunting-grounds. Like a veritable sentinel on guard, the shrike stands in wait upon his chosen Si)ot, ready to pounce willi unerring aim upon the first little bird that may dare to rustle in tlie nearest bush.'' (Coues.) Besides the small native birds that are thus destroyed, the shrikes are known to attack the imported English sparrow. 122 SHRIKES. WAXWIXGS, SWALLOWS, AND TANAGERS. 123 On this account it has been recommended that they be pro- tected by law. Shrikes also feed upon shrews and mice and many kinds of insects, including grasshoppers, caterpillars, crane-flies, and ground, tiger, carrion, and leaf beetles. Dr. S. D. Judd, Avho has made a careful study of the food of this species, writes : " The present investigation shows that bene- ficial birds form less than one-fourth of the food of the butcher- bird. It also shows that, in addition to being an enemy of THE GREAT NORTHERN SHRIKE. mice, it is a potent check on the English sparrow and on several insect pests. One-fourth of its food consists of mice ; another fourth, grasshoppers ; a third fourth consists of na- tive sparrows and predaceous beetles and spiders, while the remainder is made up of English sparrows and species of insects most of which are noxious." ^ The young are fed very largely with grasshoppers, though mice and birds are sometimes given them. The Loggerhead Shrike is a smaller bird than the last. In some of its racial forms it is found very generally throughout ^ Div. BioL Surv., U. S. Dept. Agr., 1898, Bull. No. 9, p. 20. 124 BIRDS IN THEIR RELATIONS TO MAN. the country in summer, retiring southward at the approach of winter. Inhabiting a warmer climate than its northern rela- tive, it is able to subsist more largely upon insects. In eighty-eight stomachs reported by Dr. Judd,^ only seven birds were found. Mice formed fifty per cent, of the winter food, or sixteen per cent, of that for the wliole year. Beetles and their larvae constituted twenty per cent., of which half were predaceous. Caterpillars, grasshoppers, wasps, and spi- ders were all found in considerable numbers. The nestlings are fed mainly upon insects, with an occasional mouse or small bird. Although the loggerhead shrike destroys a few birds and beneficial insects, these seem to be more tlian compensated for by its destruction of mice and noxious insects. THE WAXWINGS. The beautiful family of waxwings {Ampelidce) is repre- sented in North America by three species, only one of which is at all common and widely distributed. Of the other two, one, the Bohemian waxwing, is found in the far North, coming to the southern line of Canada in the winter, and the other, the shining fly-snapper, occurs in the Southwestern States. Another species inchided by some ornithologists in this family is Townsend's fly-catching thrush, a peculiar bird found in the Rocky Mountain region. The only member with which we are especially concerned in the present connection, however, is the handsome Cedar Waxwing, or Cedar-Bird, sometimes also called the Cherry- Bird. This '• gem of ornithological beauties" is found in nearly all the United States and throughout a large part of Canada. It commonly goes in small flocks which wander from place to place in search of food, and is usually present in all but the most northern States both winter and summer. 1 Div. Biol. Surv., U. S. Dept. Agr., 1898, Bull. No. 9, p. 20. SHRIKES, WAXWINGS, SWALLOWS, AND TANAGERS. 125 Its name has been given it because of its fondness for cedar- berries, to obtain Avhich it frequents cedar thickets. " These birds are exceedingly hardy and voracious, and for this reason have become adapted to a wide range of food. During the early spring and summer they are said to feed almost exclu- sively upon insects, and during the last of July and August they feed to a considerable extent upon them. They are dex- terous fly-catchers, and when in the woods they labor in a field almost peculiar to themselves. They often station them- selves upon the top- most branches of some dead tree-top which commands a view above the forest, and there watch hours together for insects, every few minutes beating off and up into the air to secure the winged forms that are passing above them. On the borders of woods they often fly out six or more rods for passing insects. Besides being fly-catchers they search among the foliage of trees for larv?e of various kinds." ^ Unfortunately, the cedar waxwings are also very fond of cherries, and on this account are in bad re- pute among fruit-growers. Yet it has been shown that they generally eat only the earliest cherries, and there can be little doubt that during the year they abundantly pay for the fruit taken during the cherry season. In some localities cherry- trees have been so generally planted that there is more than enough for birds and men ; in such places the depredations THE CEDAR-BIRD. F. H. Kin^. 126 BIRDS IN THEIR RELATIONS TO MAN. of these birds are not noticed. Raspberries, elder-berries, myrtle-berries, mulberries, and various other wild fruits are also eaten largely by the cedar-birds. In the orchard infested by canker-worms treated of in Chapter VI., Professor Forbes shot seven specimens out of a flock of thirty cedar-birds. The stomachs of all these were full of the worms, averaging one hundred to each, so that it Avas estimated that this flock would destroy ninety thousand of the pests if they stayed in the orchard a month. Among other insects which are known to be eaten by this species may be mentioned beetles, crickets, crane-flies, lace- wing flies, and ichneumon-flies. At the Department of Agriculture the food-contents of one hundred and fifty-two stomachs of this species have been examined, the results showing that seventy-four per cent, of the food consisted of wild fruits, thirteen per cent, of cultivated fruits, only five per cent, of this being cherries. The remaining food con- sisted of insects, — grasshoppers, bugs, bark-lice, and beetles (among the latter the elm-leaf beetle) being the principal items of the insect bill of fare. An exceedingly iuteresting account of the nesting habits of the cedar-bird has been given by Herrick. "The food con- sisted of choke-cherries and red bird-cherries, varied with raspberries, blackberries, and blueberries, together with in- sects, which during the last days of life at the nest constituted about one-quarter of the fare." Our own observations show very similar feeding habits. In one case nestling birds were found by another observer to have been fed largely upon the little dung-beetles of the genus Aphodius. THE SWALLOWS. Few families of birds are more highly insectivorous than that of the swallows (Hirundinkke). Members of this group have long, pointed wings, small feet, and n short, broad, deeply cleft bill, well adapted to catching insects in the air. SHRIKES, WAXWINGS, SWALLOWS, AND TANAGERS. 127 They are migratory, having extraordinary powers of flight, and are almost constantly on the wing. " The habits of swal- lows," writes Dr. Coues, " best illustrate the modifying influ- ences of civilization on indigenous birds. Formerly they all bred on cliffs, in banks, in hollow trees, and similar places, and many do so still. But most of our species have forsaken these primitive haunts to avail themselves of the convenient THE BARN-SWALLOW. {After Biological Survey.) artificial nesting-places that man, intentionally or otherwise, provides. Some are just now in a transition state ; thus, the purple martin in settled parts of the country chooses the boxes everywhere provided for its accommodation, while in the West it retains the old custom of breeding in hollow trees." On account of this adaptability to the environments of civilization, swallows should be encouraged as nuich as pos- 128 BIRDS IN THEIR RELATIONS TO MAN. sible by having breeding-places provided in barns and about premises. A little trouble in this direction will be more than repaid by the destruction of injurious insects. There are seven species of North American swallows, five of which are fairly abundant. Of these the Barn-Swallow is one of the commonest, occurring and breeding throughout most of Canada and the United States. Too many of the new barns are so planned that these birds cannot get inside to build their nests and rear their young, but the wise farmer will leave openings for this purpose. Most of their food is captured on the wing, and consists of small moths, two- winged flies, especially crane-flies, beetles in great variety, flying bugs, and occasionally small dragon-flies. The young are fed with insects. During "locust years" in Nebraska, Professor Aughey found that these swallows fed very largely on the pests after the latter began to fly : of three specimens shot after the middle of June, two contained thirty-four locusts each and the third one thirty-seven locusts. At such times they appear to feed almost exclusively on locusts, as their stomachs con- tained very few other insects. The Cliff-Swallow, or Eaves-Swallow, is irregularly dis- tributed over the United States, breeding abundantly in many localities and being rare in other districts. It flies over up- land meadows and pastures, often skimming along near the surface of the ground to catch the numerous leaf-hoppers and other insects found there. A single specimen shot by Professor King while the bird was skimming over a wheat- field contained twelve leaf-hoppers, seven two-winged flies, including one large crane-fly, six small beetles, and two medium-sized ichneumon-flies. It has been reported to catch numbers of small grasshoppers ; and six specimens taken in Nebraska after the western locusts had begun to fly had eaten two hundred and twenty-nine of these insects, — an average of thirty-eight to each bird. Five specimens studied by Pro- SHKIKES, WAX\VI.\(;S, SWALLOWS, AXD TANAGERS. !•_><) fessor Forbes had ealcn aiils, was})s, irhneumon-llies, ground- beetles, fungus-beetles, curculios, leaf-beetles, two- winged flies, and certain bugs. The benefits derived from this bird appear to be inuf'li greater than any injury it may do in eating para- sitic insects. The White-bellied Swallow appears to be less generally abundant than the last-named species. It is found throughout temperate North America, migrating early in autumn to the Southern States and beyond. Its nest is built in holes in dead stumps, especially those standing in shallow water, although in some localities the birds are taking to martin- boxes for the purpose. The food consists of dragon-flies, the smaller species of which these birds feed upon to a con- siderable extent, crane-flies and other Diptera, winged plant- lice, grasshopjiers, weevils, click-beetles, rove-beetles, and various other Coleoptera, winged ants, ichneumon-flies, and many other insects. In autumn, just before leaving for the South, these and other swallows feed largely on the fruit of the bayberry or waxberry (^Myriea cerifera). The fact that many dragon-flies are eaten by this bird apparently indicates that it is not an unmixed blessing, but in our present igno- rance of the precise economic status of these insects compara- tively little weight can be given to this circumstance. The Bank-Swallow is the most widely distributed American member of its family. Besides America it occurs in Europe, Asia, and Africa. It breeds abundantly in holes made in natural or artiflcial embankments, and, unfortunatt'ly, suffers largely in many parts of the United States from the budding scientists of juvenile age who rob birds' nests for the sake of the eggs. The young are fed on grasshoppers and other insects ; the adults are insectivorous, although they often eat the fruit of the bayberry late in sunmier or early in autumn. No swallow is more flimiliar about the haunts of man than the Purple Martin. It is an abundant species and readily nests in boxes provided for the purpose. It is a great insect- 9 130 BIRDS IN THEIR RELATIONS TO MAN. HEAD OF PURPLE MARTIN. eater, but, unfortunately, it seems to include many beneficial as well as injurious insects on its bill of fare. Apiarists charge it with feeding on bees, although some observers con- tend that it takes mostly drones. Dr. Packard found one of the compartments of a martin-box " literally packed with the dried remains of the little yel- low and black squash-beetle." Professor King found that the stomachs of four eight-days- old nestlings contained, re- spectively, " (a) two butterflies (^CoUas philodice and a skip- per), six honey-bees, and many bits of shells of small mol- lusks ; (6) two large dragon- flies, a large bee-fly, two honey-bees, and bits of shells of small mollusks ; (c) one large dragon-fly, three honey-bees, and fragments of the shells of small mollusks ; {d) two medium- sized dragon-flies, one honey-bee, and small pieces of shells." Another young bird recently from the nest had eaten tiger- beetles. These young birds certainly make a poor showing for the usefulness of the species, but I do not believe that their food fairly represents the food of the birds as a whole. The adults would be much more Ukely to give their young the larger insects they caught, reserving for themselves the smaller forms. Ten Nebraska specimens examined by Pro- fessor Aughey had eaten two hundred and sixty-five locusts and one hundred and sixty-one other insects. " No bird of North America," writes Mr. Ridgeway, "is more deserving of protection and of encouragement to live about the habitations of man than the purple martin. One pair of them will destroy more insects in a season than all the English sparrows in a township will kill in their life-time. Besides, their notes are pleasing to the ear, and their actions, both when on the wing and when perching upon their boxes, are extremely interesting." SHRIKES, WAXWINGS, SWALLOWS, AND TANAGERS. 131 THE TANAGERS. The family of tanagers (Tanagridoe)^ which in tropical Aiiierica contains many brilliant and beautiful species, has several representatives in the United States, only two of which connnonly hihabit the eastern region. All are brightly colored birds, with a stout bill, notched at the tip and having a tooth or lobe near the middle. They are migratory in habits and subsist upon both insects and fruit. The Scarlet Tanager is the most strikingly colored of any of our birds. The male is of a brilliant scarlet, with deep- black wings and tail ; the female is olive-green Eibove, green- ish yellow below, with wings and tail more or less dusky. This bird is connnon throughout the Eastern States, ranging westward a little beyond the Mississippi. It nests in trees in woods and groves, and wniters in the South. Its food consists mostly of insects, of which it takes a varied assort- ment. The stomachs of various specimens have been found to contain ants, ichneumon-flies, including what was thouglit to be the large Thalessa lunator, many caterpillars, crane-flies and other Diptera, curculios, click-beetles, leaf-chafers, and various other beetles, grasshoppers, a few bugs, an occasional dragon-fly or spider, and several harvest-spiders. A single Nebraska specimen shot in the autunni of 1874 contained thirty-seven locusts. Three nestlings less than a week old, examined by Professor King, had eaten four caterpillars, one fly, one small grasshopper, one bug, besides undetermined fragments. The feeding habits of the Rose Tanageh, or Summer Red- BuiD, seem to be less known than those of the last-named species. One specimen taken in Maryland had eaten wild blackberries, a bee, and a was[). Mr. Robert Ridgway says that its food consists to a great extent of hornets, wasps, and bees, because of which it is sometimes called " red bee-bird." It is more southerly in distribution than the scarlet tanager. CHAPTER XII. THE FINCHES AND SPARROWS. The family Fringillidce, to which belong the sparrows, finches, buntings, and grosbeaks, contains more than one- seventh of the species of North American birds. It is even richer in forms than the warblers, althougli the latter doubtless destroy many more insects than do tlie former. The finches, as a rule, are birds of moderate size, of sombre colors, and of both vegetivorous and insectivorous habits. The majority of them subsist upon seeds and grains of various kinds ; but some eat other vegetation, including buds and fruit, and many feed to a large extent upon insects. They are more or less migratory, and some of them usually go in small fiocks. They are found in all sorts of situations. Many of the species are excellent singers. Of the true grosbeaks occurring in our fauna, the Evening Grosbeak is a western form that occasionally migrates in winter to the region of the great lakes and even farther east. It feeds upon the seeds and buds of various trees, such as the pine, poplar, spruce, maple, black ash, and cotton-wood, and has been found sometimes to include grasshoppers in its bill of fare. The Pine Grosbeak is a northern form which in winter ranges southward through the New England and other Northern States. The birds travel in small fiocks, Avhich spend much of their lime in coniR^rous forests, feeding upon buds of pine and spruce ; they also eat the buds and seeds of white ash, basswood, alder, birch, apple, jx^ar, and poplar, as Avell as the berries of tli(^ red cedar and the high-bush cranberry. In winter they often subsist largely upon the pulp and seeds of frozen apples. In some instances they 132 THE FINCHES AND SPARROWS. 133 have been known to injure fruit orchards by feedui<,' upon the buds, but this is a rare occurrence. Professor Aughey found that five Nebraska specimens taken during winter had eaten, along with various seeds, a large number of eggs of the Rocky Mountain locust. The pine grosbeak is one of the largest species of this family in the more northern States. The Purple Finch is a handsome and somewhat famihar bird, found throughout nearly all of the United States. It is migratory and usually goes in flocks, except during the breed- ing season. In the Northern States its nest of vegetable fibre is frequently placed on trees near houses. Unfortunately, the feeding habits of this species are not all that could'^be desired. Many years ago an eminent ornithologist w^rote concerning the purple fi.nch : "This is a winter bird of passage, coming to us in large flocks from the North in September and Octo- ber; great numbers remaining with us in Pennsylvania during the whole whiter, feeding on the seeds of the poplar, button- wood, juniper, cedar, and on those of many rank weeds that flourish in rich bottoms and along the margins of creeks. When the rainy season is very severe, they proceed to the South, as far at least as Georgia, returning north early in April. They now frequent the elm-trees, feeding on the slender but sweet covering of the flowers ; and as soon as the cherries put out their blossoms they feed almost exclusively upon the stamens of the flowers ; afterwards the apple- blossoms are attacked in the same manner ; and their depre- dations on tliese continue until they disappear, wliich is usually about the tenth or middle of May.'' Many later ob- servers have seen the purple linch eating the tender portions of the buds and blossoms of apple, cherry, plum, and peach, although little real damage seems to be done by it, and, as a partial offset, it is also known to devour aphides and various caterpillars. The beautiful little American Goldfinch, or Thistle-Bird, is familiar to all residents of temperate North America who 134 BIRDS TX TIIEIR RELxVTIONS TO MAN. pay the slightest attention to feathered beauty. Except during the breeding season these birds wander about in small flocks, stopping wherever a supply of seeds extends an invita- tion. They are especially fond of the seeds of composite plants, like the thistle, dandelion, and sunflower, and in winter frequently dine upon the balls of the button-bush, although they more commonly eat the seeds of ragweed and various other noxious plants. At tliis season also they get much of their food from the seeds of birch and similar trees. They occa- sionally attack seed intended by man for other purposes, but the benefits we derive from them more than compensate for the injury so done. They also take a few insects, having been re- port(^d to devour plant-lice, the Hessian fly, and the Rocky Moun- tain locust. The downy nest is built very late in the season, generally in July, and from four to six young are reared, the latter being fed largely upon the seeds of thistles. The Snow-Bird, or Snow-Buxtixg, is one of the most beneficial of the seed-eaters. It breeds in the summer in the Arctic regions, and in winter visits the iN'orthern States in large flocks. It commonly frequents cultivated fields, where there is an abundance of seeds of weedy plants, like the fox- tail grass (Setaria) and bindweed {Convolvulus). The snow- birds keep close to the ground, seldom staying in trees, and are welcome visitors, adding much to the scanty life of our winter landscapes. The lovely little bird celebrated by John Burroughs as the Vesper-Sparrow, and known also as the Grass-Finch, or Bay-winged Bunting, is one of the most abundant of the AMERICAN C.OLDFINCH. THE FINCHES AND SPARROWS. 135 sparrows, and can readily be distinguished from its relatives by the white lateral tail-feathers shown when it flies. It is widely distributed and partially migratory. It frequents grass-lands and cultivated fields, in the Western States often making its nest in corn-fields. Two or three broods are reared each season, with from four to six young in each brood. The food of a number of New Hampshire nestlings consisted of spiders and larvae of various kinds. The diet of thirty-seven Wisconsin adults was studied by King : of these '' thirty-one had eaten various small weed seeds ; five, four grasshoppers ; one, eight grasshoppers' eggs ; four, ten larvae ; fourteen, twenty-seven small beetles ; three, eight moths ; one, three flies ; one, three land-snails ; one, two kernels of wheat ; and one, a kernel of rye." The examination of one hundred and thirty stomachs of this species at the United States Department of Agriculture showed that two-thirds of the food of the year is of vegetable matter, the rest being largely insects and spiders. In winter the food consists chiefly of the seeds of weedy plants, espe- cially ragweed, amaranth, lamb's-quarters, and purslane. In summer the birds eat chiefly insects, especially grasshoppers, beetles, cutworms, army-worms, and other sorts. In July grasshoppers form nearly half the sparrows' food. The Tree-Sparrow, which comes down from the far North, usually towards the end of October and remains with us until April, not only serves to enliven winter, but at the same time does much good by destroying great quantities of weed seed. The good work laid down by the chipping, field, vesper, savanna, and the other sparrows, less hardy than this boreal species, is quickly taken up and continued until their return. In New Hampshire the date of the chipping-sparrow's departure is almost precisely that of the tree-sparrow's arrival, and vice versa. In the Northern States, except along the coast, the snow is so deep that but few seeds eaten by fliis sparrow arc left 136 BIRDS IN THEIR RELATIONS TO MAN. uncovered, and for that reason comparatively few birds remain there during the hardest part of the winter. A httle farther south they are very abundant in cold weather, and the amount of seed they consume is wellnigh incredible. Professor Beal ^ has estimated that during the two hundred days they average to remain in the State of Iowa, reckoning ten sparrows to tlie square mile and one-fourth of an ounce as the daily ration, eight hundred and seventy-five tons of weed seed are eaten by this species alone. The only complaint to be entered against it is that sometimes it eats the seeds of cultivated millet left exposed in shocks out-of- doors. The White-crowned and the White-throated Sparrows have much the same feeding habits as the tree-sparrow. The seeds of ragweed and the various sorts of smartweed, knot- W'Ced, and bindweed form a chief part of their winter food. About tliree-fourths of the food of both species consists of vegetable matter, the rest being insects and allied forms. These two species differ from most of the other s})arrows in that they take very few grasshoppers and comparatively little grass-seed, while on the other hand they take a small per- centage of wild fruit. The Pacific coast form of the white-crowned sparrow — sometimes called Nuttalfs sparrow — has been carefully studied by Dr. T. S. Palmer. Unlike most of the native sparrows, this subspecies is sometimes injurious through its destruction of grain in newly sown fields or that ready to harvest. As a partial compensation, however, the!=e birds eat great quantities of weed seeds. The Field-Sparrow is an abundant and widely distributed species, occurring in summer in southern Canada and the Northern States and in winhT in the Southern States. Its food is approximately forty per cent, animal and sixty per See Some Coiiiinoii Birds in their Reliition to Agi-iculliirc, \k 2S. THE FINCHES AND SPARROWS. 137 cent, vegetable matter. Insects and the seeds of weeds and grasses are eaten in a way very similar to that of the other ground-loving sparrows. THE FIELD-SPARROW. {After Biological Survei/.) The sombre-colored Savanna-Sparrow, either in the typical form or in that of the closely related species and subspecies, is found throughout almost all of North America. It is a ground-loving bird, and abounds in meadows and pastures and along highways, as well as by the margins of brooks and in stul)ble or corn-fields. It feeds upon the seeds of weeds and grasses, and also upon such insects as l)eetles, moths, and caterpillars, animal and vegetable juatter being abont equally divided. It has a special liking for beetles. lis nest is placed in a clump of grass and carefully concealed from vi(nv.

It is abundant and widely distribnicd, and an un- assuming but extremely usefnl lifllf bird, wliicji j)r()])aJ)ly 138 BIRDS IN THEIR RELATIONS TO MAN. suffers more from the attacks of cats than does any other species. The neat hair-lined nest is placed in a shrub or tree, often near a house. Its food consists of insects and small seeds: of the former smooth caterpillars, like cutworms and canker-worms, are favorites, but beetles, grasshoppers, moths, ants, and bugs are also eaten. It has been observed feeding upon the common cabbage-worm (Fieris rajjw). Dr. Judd's studies of two hundred and fifty stomachs of the chipping-sparrow show that insects and spiders form thirty-eiglit per cent, of the food of the adults, the remainder being seeds. The seeds of grasses alone form forty-eight per cent., more than half of it being crab-grass and pigeon-grass. In our study of the feeding of the nestlings of this species we saw the parent birds come to the nest almost two hundred tunes in one day from daylight to dark. The young are fed with smooth caterpillars of various sorts, as well as grass- hoppers, crane-flies, spiders, and similar creatures. The JuNco, or Black Snow-Bird, is a common winter resi- dent or migrant in most of the United States, breeding in the northern tier of States and in Canada. Its principal food consists of the seeds of weeds and grasses, although in summer a good many insects are eaten, these forming about one-half of its summer diet. No bird is a more welcome harbinger of spring than the Song-Sparrow. When one hears its cheery song on a bright March morning, he knows that the frost king is vanquished and will soon retreat before the living armies that usher gentle spring to the front. This bird is indeed "a hearty, sunny songster, Avhose quivering pipe is often tuned to the most dreary scenes." The typical form inhabits the United States and Canada, while the western region has several closely allied subspecies. It abounds in shrubbery everywhere, along road-sides, fences, brooks, and swamps. It winters in the Middle States and southward, some speci- mens migrating north very early in spring, into those States Till-: FIXCHKS AM) ^IWHl^oW l:;!l THE SONG-SPARKOW. {After Biohnjieiil Siirvei/.) where llicy have iiol i)a.ssi'd llio wiiilcr. lis iicsl is placed on the ground or in a low bush, and two or tlircc broods are reared each season.

In spring it feeds upon the seeds of dandelion. When canker-worms are abundant it feeds freely upon them, and at other times takes a great variety of insects, such as ground-beetles, grass- hoppers and their eggs, occasionally a lady-bird beetle and various noxious beetles, moths, dragon-flies, crickets, spiders, bugs, two-winged flies, and myriapods. Considering its abundance, com])aratively few people are familiar with the song or api)earance of the Swamp-Sparrow. This bird is a recluse, living in the tangled shrubbery of lowland swamps, where he may often be seen by the nature- lover who will i)atiently penetrate to liis retreat. This spe- cies breeds connnonly in New England, rearing two or three broods each summer, and spends tlie winter in the South. Insects appear to form about half its food: among those taken from the stomachs of this si)ecies we may mention beetles, moths, bugs (including plant-lice and leaf-hoppers), grasshoppers, caterpillars (among them case-l)earers of the genus Coleophora), and a tew parasitic Hymenoptera. They also eat snails and the seeds of various grasses, sedges, and 140 BIRD^^ IN THEIR RELATIONS TO MAN. other weedy plants, the latter forming fully one-half of their food. The army-worm is perhaps the most destructive in- sect w^hich the swamp-sparrow is likely to assist in checking, because the insect develops especially in the marsh lands where tlie birds live. ■ ''The DicKcissEL," writes Dr. Judd, in his admirable mono- graph,^ '-formerly raised its broods over a considerable portion I' THE DICKCISSEL. {Affrr liiolofjical Snrveit.) of the United States east of the Rocky Mountains ; but two or three decades ago it abandoned the Eastern States and now rarely breeds east of the Allegheny Mountains. In autunm it migrates to Central and South America. In some localities it is known as the little meadow-lark, because its coloring is like that of the meadow-lark, even to the black locket on the ^ The Relation of Sparrows to Agriculture, Bull. No. 15, U. S. Bio- logical Survey. THE FINCHES AND SPARROWS. 141 breast of brilliant yellow. Most sparrows are gregarious, but dickcissels move about in pairs or little family groups. In many places they are so numerous that a score of individuals may be found in every hay-field and meadow ; and the species is as characteristic of such localities as the robin is of the New England lawn, or the mocking-bird of the Florida plantation. The song consists of a series of monotonous insect notes, re- peated incessantly from early morn to late afternoon, resembling somewhat the heat-suggestive tones of the grasshopper." The food of the dickcissel is especially noteworthy on account of the grasshoppers and crickets eaten : in summer these constitute more than half its dietary. The vegetable food consists of the seeds of weeds and grasses. In the shrubbery along the borders of woodlands one may often see a black bird with chestnut sides skulking from bush to bush or scratching the leaf-covered soil. This is the Che- wiXK, or TowHEE Bunting, one of the larger fmches, which is common in the eastern United States and Canada. It is migratory ; its nest is placed upon the ground, and two broods of young are reared each season. Its food consists of small seeds, grains, and fruits, as well as many insects ; among the latter are included . moths, beetles, ants, wasps, and ichneumon-flies, cockroaches, grasshoppers, walking-sticks and their eggs, besides larva? of many kinds. The young are fed upon insects similar to those eaten by the adults. The beautiful Rose-breasted Grosbeak is especially noted for its destruction of Colorado potato-beetles. Observers in Connecticut, New Jersey, New York, Michigan, Illinois, Iowa, Wisconsin, Miimesota, and other States have repeatedly no- ticed this habit, wliicli in some localities has given the species the name of "potato-bug bird."' The following sentences from the pen of Professor F. E. L. Beal illustrate its economic value: "The rose-breasted grosbeak feeds upon the Colo- rado potato-beetle in all its stages. I observed this habit in central Iowa, and noficed that it became each year more 14!^ BIRDS IN THEIR RELATIONS T(3 MAN. general, the birds of this species seeking the potato-field more and more each season. I observed one small field near my house that was much infested with the beetles, but the birds found it, and in a few weeks I searched the field and could not discover a single beetle young or old/' Of eight stomachs THE ROSE-BREASTED GROSBEAK (After Biulotjiail Survey.) of this species examined by King, six contained small seeds, two seven beetles, and one berries, w^hile specimens ex- amined by Forbes had eaten canker-worms, army-worms, and other caterpillars, wood-boring, leaf-chafing, and snout-beetles, as well as Hymenoptera and weed seeds. Two Nebraska specimens examined by Aughey had about a dozen locusts in each stomach. As a result of the examination of some four thousand stomachs of sparrows of many sorts, collected all over the United States, Dr. S. D. Judd concludes that '• during the colder half of the year the food of these birds consists almost entirely of the seeds of weeds." And he records this intensive study of the effect of their work : " On a farm in Maryland, just outside the District of Columbia, tree-sparrows, fox- THE FINCHES AM) SPAHHOWS. 143 sparrows, wliilc-throats, son^-sparnjws, and juiicus fairly swarnied during'- Decoiiibcr in tiie briers of the ditches be- tween tlie corn-fields. They came into the open fields to feed upon weed seed, and worked hardest where the siuart- w^eed formed a tangle on low ground. Later in the season the place was carefully examined. In one corn-lield near a ditch the smartweed formed a thicket over three feet high, and the ground beneath was literally black with seeds. Ex- amination showed that these seeds had been cracked open and the meat removed. In a rectangular space of eighteen square inches were found eleven hundred and thirty half seeds and only two whole seeds. Even as late as May 13 the birds were still feeding on the seeds of these and other weeds in the fields ; in fact, out of a collection of sixteen sparrows, twelve, mainly song, chipping, and field sparrows, had been eating old weed seed. A search was made for seeds of vari- ous weeds, but so thoroughly had the work been done that only half a dozen seeds could be found. The birds had taken practically all the seed that was not covered ; in fact, the song- sparrow and several others scratch up much buried seed.'' This summary of the economic relations of the commoner members of the finch family shows that, on the whole, these birds serve a very useful purpose by destroying the seeds of noxious plants and the lives of injurious insects, but that some species, like the purple finch and pine grosbeak, are occasionally destructive to the buds of fruit-trees. The most striking particulars brought out by a study of their diet are the enormous amount of weed seed taken during winter and the extent to which these so-called seed-eaters take insect food in spring and summer, especially in the })resence of an unusual abundance of an edible species. For example, in an orchard infested by canker-worms forty-seven members of this family had eaten ninety-one per cent, of insects and only seven per cent, of seeds, canker-worms alone making forty per cent, of the food. CHAPTER XIII. THE ENGLISH SPARROW AND THE STARLING. THE ENGLISH SPARROW. The European house-sparrow, familiarly known to Ameri- cans as the English sparrow, was first introduced into the United States in 1850, Avhen eight pairs were brought from England to Brooklyn, New York. These did not thrive, and two years later a large lot of the birds were brought to the same city and liberated during the spring of 1853 in Greenwood Cemetery. During the next twenty years extensive importa- tions were made, the birds being brought from England and Germany and liberated in Maine, Rhode Island, Massachusetts, Connecticut, New York, Pennsylvania, Ohio, and Texas. The largest consignment was that received in Philadelphia, when one thousand birds were set free. After the sparrows had become established in these various centres, misguided men assisted their migrations by carrying them to towns and cities in wliich they were not yet found. Everywhere they were petted and watched over; in some States special laws were enacted to protect them : tlie people fostered an evil that is not now easily subdued. Even when kindly Nature sent the great northern shrike to check the sparrow's increase on Boston Common, the authorities hired a man to shoot the shrikes and save the sparrows, — a reversal of the wiser process. The sparrows seem to have been first imported to destroy canker-worms and other insects affecting fruit- and shade- trees. People annoyed by the defoliation of avenues of shade-trees hailed with delight the feathered friends that were to rid tlicni of their crawling foes. The enthusiasm passed from town to town, resulting in a sparrow boom that sent the prices of American-bred birds so high that European 144 THE EXGTJSIT RPARROW WD THK STARLIXG. 145 importations weiv clicapcr. Many iiniiii<,a-anls from tlic Old World cherished the birds on account of their associations witli the scenes of early Ufe ; and native Americans encour- aged them because of tlieir supposed insectivorous habits, or from the desire to have birds to enliven city streets and premises. Without stopping to inquire the reasons for the hospitalities they received, the sparrows made the mos+ of iheir opportunities and throve apace. From the time of their first general introduction to the present, says Professor Barrows, "the marvellous rapidity of the sparrow multiplica- tion, the surprising swiftness of its extension, and the pro- digious size of the area it has overspread are without parallel in the history of any bird. Like a noxious weed transplanted to a fertile soil, it has taken root and become disseminated over half a continent before the significance of its presence has come to be understood.'' After the little foreigner liad been coddled through tlie trying period of acclimation and had taken possession of the country, the popular mind underwent a revulsion of feeling towards liim. He was declared a nuisance because of his noise, reviled as a humbug, and sh(jt for being a poacher. But the sparrow kept on, like a true Anglo-Saxon, in the even tenor of his way. In many places he suffered severely, but he was so thoroughly disseminated and his fecundity was so great that any loss man could inflict was of little conse- quence to his race. Of late years there is less heard against him than formerly, and it seems as if the people are at last in the mood to make the best of a bad bargain. As regards food habits of tlie English sparrow, it is defi- nitely known that the adult birds eat a few insects, — cater- pillars, moths, beetles, etc., — and that the young are fed quite largely on insects. In the country and the suburbs of towns, they may often be seen searching the lields for grasshoppers and other insects, while feeding young, as assiduously as even the chipping-s})arr()w. 10 146 • BIRI>^ 1^^ THEIR RELATIONS TO MAN. A lew years ago tlie officials of I he United Stales Department of iVgriciilture examined the stomachs of five hundred and twenty-two sparrows from many different localities : insects of any kind were found in only one hundred and two of these ; and of the insects so found forty-seven were regarded as belonging to noxious species, fifty to beneficial species, and thirty-one to species having no economic importance. The testimony of those best able to judge is almost unanimously to the effect that as destroyers of noxious insects the sparrows are worse than useless. In his report upon the insect con- tents of the live hundred and twenty-two sparrow stomachs just referred to, Dr. C. V. Riley says : '• I do not know of any fact that more strongly indicates the relative uselessness in destroying injurious insects of the sparrow, as compared with many native birds which it drives away, than by a com- parison of the insect food taken by a single cuckoo shot in Washington, June 22, 1887, the stomach of which contained about two liundred and fifty half-grown web-worms, one large cerambycid beetle and its eggs, one large plant-bug, and one snail, while in bulk the contents in this case rather exceeded the combined insect contents of the five hundred and twenty- two sparrow stomachs exannned." In 1880 Professor S. A. Forbes examined the stomachs of twenty-five Illinois spar- rows, and reports that at a 'Mime when thirty per cent, of the food of the robin, twenty jxt cent, of that of the cat-bird, and ninety per cent, of that of the bluebird con- sisted of insects, no insects were found in the stomachs of these birds except traces of three grasshoppers, making per- haps six per cent, of the food." To show that results of this kind in investigating the si)aiTow"s diet are not confined to America, we may add that of an English ornithologist who studied during a whole year the food of young and adult sparrows. For the latter he found that seventy-five per cent, of the food consisted of wheat and small grains, ten per cent, of seeds of weeds, four per cent, of green peas, three per THE ENGLISH SPARROW AND THE STARLING. 147 cent, of beetles, two per cent, of caterpillars, one per cent, of flying insects, and five per cent, of other things. During the first sixteen days of the nestlings' life, forty per cent, of the food consisted of small grains, forty per cent, of cater pillars, and ten per cent, of small beetles. If the sparrow had no greater sin to answer for than that of not destroying a sufficient number of injurious insects, he might be left in peace. But he is charged with a long list of sins of commission that are not so easily condoned. Obser- vations frequently repeated in widely separated localities have established beyond doubt the fact that he habitually destroys, either for food or pleas- ure, the buds and blos- soms of a great variety of fruit, shade, and or- namental trees. On the list of trees and shrubs so attacked we find the peach, pear, grape, plum, cherry, apple, currant, maple, elm, evergreens, orange, lilac, and others. This injury is accom- plished in spring and often results in the total destruction of the fruit crop. Not content, however, with nipping the fruits in the bud, the spar- rows continue their attacks later when the fruits are maturing: among the ripe or ripening fruits they so attack we may men- tion grapes, cherries, blackberries, straw^berries, raspberries, apples, pears, peaches, plums, tomatoes, and currants. The injury to grai)es is occasionally quite severe, and that to early apples is ])articularly vexatious, as they peck holes, similar to APPLE PECKED BY ENGLISH SPARROWS. {After Biohigical Surveij.) that shown in tin tigur al)()v m the rii)ening fruit. Garden 148 BIRDS IN THEIR RELATIONS TO MAN. vegetables are often attacked, green peas being especially liable to injury. In many localities it has become very diffi- cult to get a crop of peas, on account of the sparrows, Avhich destroy the blossoms at first and later attack the pods. Green corn, lettuce, cabbage, and other vegetables are also attacked, and not infrequently the newly planted seeds are scratched to the surface and devoured. The list of the sparrow's sins of commission is by no means ended. In attacking grain of various kinds these birds probably cause more loss than in all the ways mentioned above. From the time small grains, like wheat and oats, are planted until safely gathered in the bin, they are liable to suffer from sparrow attack. The greatest damage is probably done when the grain is in the soft condition which immediately precedes ripening, but it also sutfers greatly at the time of planting and in the ''shock" just after harvesting. Besides the grains already mentioned these birds attack Indian corn, rye, barley, sorghum, rice, and buckwheat. These charges against the sparrow's food habits are grave indeed. There is something to be said in Jiis favor, however. Mr. Charles W. Nash ^ states that " Sparrows, like the majority of birds, will not often eat the spiny larvae of Vanessa antiopa, which is one of our shade-tree pests that few birds will touch. Besides this I have seen them take moths of almost any kind, including the large cecropia and luna moths and the tussock moth (both the winged male and the wingless female), beetles of many kinds, even such large species as the l)i/fiscu.% which they find on the sidewalks beneath the electric lights, to which the beetles are attracted at night, the green cabbage- worm (the larva of the cabbage-butterfly) — of these they eat great numbers. They also hunt about fences and take the pupae of this same buttertly. The currant-worms and mature 1 See "The Birds of Ontario in relation to Agriculture," second edi- tiou, ]). G8, ])ul)1i,sli('n^iS\^;»i^^^^^^^/;^'^ THE CROW BLACKBIRD. {After Biologkal Survei/.) others of their tribe, they are accused of various misdeeds : the eating of grain is the Avorst of these. Throughout the year more or less grain is taken, though in summer insects receive the major part of their attention. All sorts of grain as well as wild and cultivated fruits and many kinds of seeds are eaten. Of the grains, Indian corn is taken in greatest amount. It has been shown, by the examination of two thousand two hundred and fifty-eiglil sloinaclis al AVashington, tli;il coni is THE ORIOLES, BLACKBIRDS, CROWS, AND JAYS. 159 consuiried every month in the year, and that it forms about half of the ve^^etable food, or a fourth of the entire con- sumption, — the animal and vegetable materials being about equal. There was little evidence to show that sprouting corn was pulled u]), and it appeared that much of the grain was waste matter picked up after the harvest. The record of the September Inrds was bad : more than half the food for that month was corn, evidently taken from the ear. In October the ratio was nearly as great. Among the animal food Avere found insects, spiders, rny- riapods, crawfish, earthworms, sowbugs, hair- snakes, snails, fishes, tree-toads, salamanders, lizards, snakes, birds' eggs, and mice. While this is an astonishing variety, everything but insects must be considered exceptional, as out of the forty- eight per cent, of animal food forty-six per cent, consisted of insects. Of these, beetles were consumed in greatest cpiantities. Scarabaeids, adult and larval, come first in point of numbers. As is well known, these beetles either as larvae or adults are consumers of vegetable matter, and many of them are distinctly noxious. The large white grubs so often unearthed by the plow form a favorite article of food : many stomachs were crammed with them. Snout-beetles, among which were curculios and weevils, were found in great num- bers in stomachs taken during summer. Bollworms and army-worms are also eaten by these birds. Grasshoppers were found to be largely eaten also : more than thirty were often found in a single bird. This fact, when coupled with the fact that many 'hoppers and caterpillars are fed to the young, demonstrates that in sunmier at least the crow black- bird is a good friend in helping to keep down the grasshopper pesL Caterpillars and stink-bugs were often in evidence. In writing of the food of the young crow blackbirds Dr. S. D. Judd says: "The first meal of the nestlings often consists of plum[) spiders of soil texture, which suit the delicate embry- onic stomach ; and these, together with tiny young grasshopper 160 BIRDS IN THEIR RELATIONS TO MAN. nymphs and soft small cutworms, continue for a while to form the food. As the stomach develops, however, the diet changes ; such hard insects as beetles soon become a part of the fare, and by the time the young blackbirds are nearly or quite half grown their stomachs are strong enough to digest corn. Corn is then given to them freely, and in increasing quantity, until, when they are ready to leave the nest, it forms about one-quarter of their food." Practically all of the insects taken by this species are nox- ious : if allowed to increase without stint, they would eat us out of house and home. The evidence that many of them are consumed is conclusive. It is also evident that at times blackbirds are an insufferable plague. " As soon as the grain is in the ground,'' writes j\Ir. Charles W. Nash, of Toronto, Canada, " they visit the newly sown fields and help themselves liberally, varying their diet by taking as many small birds' eggs and young as they can conveniently get at. I have on several occasions seen them attack and carry off young robins, in spite of the vigorous defence set up by the victims' parents." Looking at the record from both sides there seems but one thing for a sensible man to do, — namely, so long as the bird does well, let him alone ; wlien he becomes pernicious, drive him off or kill him. In Stanley's "History of Birds" (p. 197) attention is called to the fact that a bounty for the " Purple Crackle or New England Jackdaw" is recorded in King's "Narrative" (vol. ii. p. 217), where it is stated : " A reward of three-pence a dozen Avas once awarded in that country for the- extirpation of the Crackles; and the object was almost affected, at the cost of the inhabitants, who at length discovered that Providence had not formed these supposed destructive birds in vain ; for, not- withstanding they caused great havoc among the grain, they made ample recompense by clearing the soil of noxious worms, particularly of one called the pease-beetle. For no sooner were the birds destroyed, than the insects multiplied to such THE OlllOLKS. HLACKI^.IHDS, CliOWS.

The Red-wixged Blackbird is a summer denizen of swamps and marshes throughout temperate North America. It is one of the earliest birds to ai)pear in spring and one of the earliest to leave its breeding-places, though the final departure of the great flocks that congregate in suitable places in August is [;,■:- .;■- mfi,:iii, THE RED-WINGED BLACKBIRD. {Afli'r liiologiiitl Survey. ) often delayed till October or November. While feeding their young, red-wings frequently come to the field for grasshoppers and such other insects as are to be found there. At other s(^asons they are seed-eaters for tht^ most ])art. Where a])un- dant, thry do considerable injury both to newly sown grain and to ri|)ening croi)s. In some States boiuities have been offered for their heads. Their custom of congregating in large flocks makes their ovW work very great where it occurs. n 162 BIRDS IN THEIR RELATIONS TO MAN. Their greatest depredations are committed in the grain-fields of the Mississippi Valley and in the southern rice-fields. In an examination of seven hundred and twenty-five stomachs the Department of Agriculture found seventy-four per cent, of the food to be vegetable matter, the remainder being animal, mainly insects. Weevils and snout-beetles amounted to twenty-five per cent, of the June food. Beetles formed ten per cent, of the food for the year ; grasshoppers formed about five per cent. Of grain only corn, wheat, and oats were found : together they constituted thirteen per cent, of the whole food. Weed seed, mainly ragweed, barn-grass, and smartweed, amounted to fifty-seven per cent. A sum- mary of the food examined reveals the fact that about seven- eighths of the red-wing's diet is made up of noxious insects and weed seed. Therefore, while locally guilty of damage sufficient to justify its slaughter, it would be very poor economy to persecute this bird generally. The food of the young birds consists almost wholly of in- sects of the sorts commonly eaten by the adults. The Cow-Bird is found throughout the United States, except along the Pacific coast. Its name was given in recognition of its fondness for bovine society. It is essentially a bird of the field, spending nearly all its time sean^hing for food in fields and pastures. It eats insects, grasshoppers, beetles, larva?, etc., in summer, and takes seeds of weeds and occasionally small grains at otlier seasons to a considerable extent. So far as its food habits are concerned, there is much to commend it, but as a parasite on other birds it is undoubtedly noxious. Its domestic relations are decidedly irregular. Males are more numerous than females. Polyandry is a common prac- tice. They never pair. They never build nests. By stealth eggs are deposited in other birds' nests, to be hatched and the young raised by foster-parents. Here is where the cow-birds are criminal in effect if not in intention. The cow-bird egg is laid with an uncompleted clutch. It hatches more quickly THE ORIOLES, BLACKBIRDS. CROWS. AM) JAYS. 163 than the rightful occupants ; it is larger than they, as the hosts are almost invariably smaller than cow-birds, — warblers, vireos, etc. Thus the young cow-bird is able to grow rapidly, and williiii (wo or three days is so much ahead of his foster- brothers and -sisters that he gets all the (bod and they die. it appears to be the rule that a co\v-bird"s L^i^i^ laid in a nest ruins the hopes of the birds that built it. Every young cow- bird is reared at the expense of anywhere from two to five other birds, each of which is of more vahie than he. This makes cow-birds costly. Whatever benefits we derive from their food habits are more than overcome by their parasitic habits. sv P' 4r, 17//' THE BOBOLINK. {After Biuluijical lynrvey.) In th(^ northeast quarter of the United States, it is safi^ to assert, there is no more popular bird among country folk than the Bobolink. He announces his connng by a shower of melody from the clouds. For a fortnight lie revels in bachelor freedom, in glor'ions apple-blossoms, and pours foi'lli a flood 164 BIRDS IX THEIR RELATIONS TO MAN. of song. On the arrival of the females, he quickly makes a match by ardent wooing, and with all the impetuosity of his nature settles down to family cares. No bird is a more de- voted parent. Every one on the farm is a witness to his solicitude. The mother bird is perhaps no less anxious for the welfare of her children, but she is more timid. Not alone for sentimental reasons are bobolinks prized by the inhabi- tants of their summer home-land, for they are highly thought of on account of their destructiveness to insects. During this season they eat insects almost exclusively. To the young 11 ley bring grasshoppers. Careful watching at the nest has shown that they discriminate as to color. No less than nine out of every ten 'hoppers brought to the nest are green. There appears to be no choice of species, for long-horned and short-horned 'hoppers were brought in about the same num- bers. As a rule, nymphs are preferred to adult specimens. So far as the bobolink's conduct in the North is concerned it is above reproach. Early in August there is a gathering together of families into flocks, and the movement southward is begun. Then come trying times for "bob" and his enemies. Along the coast of the Middle Atlantic States reed-birds, as they are called there, are slain for the table by untold thousands. Further south they enter the rice-fields when the grain is in the milk, and it is there they cast off virtue and become thieves. The rice-planters have abundant cause for hating them and employ destruction. There is mutual distress. It has been stated that two million dollars' worth of rice is annually destroyed. The number of birds slain is beyond reckoning. In spite of the enormous drain upon their numbers, the flocks seem as numerous as ever. It is probable, however, that they are actually decreasing. It does not seem possible that the immense numbers annually slain in the South can be made good. Then, in Ncav Hampshire, at least, farmers past THE ORTOLES. BLACKBIRDS. TROWS. A.\l> .lAV ]C:. middle asj;e state that bobolinks are not nearly so coiiinion in the fields as they were fifty or sixty years ago. While it may be that the rice destroyed is worth more than the slaughter of insects, there is no certainty that it is so, though no one can blame rice-planters for attempting to exterminate the birds. In any case, those Avho know the bobolink in his northern home can but regard with complaisance the fact that he has a place among tilings that yet exist. The ]\Ieadow-Lark, with its "bosom of prairie buttercups, its back hke the dead grass of autumn, and its song Avhich THE MEADOW-LARK. {After Biological Siirvi'i/.) harmonizes Avell with the prairie winds," is essentially a bird of tlie prairies. But it is not confined to the prairie States: from New England to Florida, from Florida to Mexico, from Mexico to Oregon, and from Oregon back again to New Eng- land, where there are open stretches of pasture and jiieadow lands, one is likely to lind the eastern meadow-lark or its western representative. In northern localities it dwells only in summer, migrating southward for the winter, ])ut in many Central States it remains throughout the year, lis nest is built on the ground in a clunip of grass and four or live young are reared. 166 HIRDS L\ THEIR RELATIONS TO MAN. The record of the food of the meadow-lark is unusually full and complete. The stomach contents of nniety-three specimens from seven widely separated States (New York, Pennsylvania, North Carolina, Tennessee, Illinois, Wisconsin, and Nebraska), taken during March, April, May, June, July, August, October, and November, have been examined by competent investigators ; the results prove beyond all doubt that this is a bird of extraordinary economic value. Thirty- three specimens from various parts of Illinois, taken during March, April, May, June, and July, were studied by Forbes, who found that three-fourths of the food consisted of insects, the peculiar animals known as "thousand-legs" and grains of corn and wheat constituting the remainder. Caterpillars formed twenty-eight per cent, of tlie food, one-half of them being cutworms and army-worms and one-fourth the hairy larvae of the family of "tiger-moths." Even during these early months grasshoppers formed thirteen per cent, of the stomach contents, and beetles of various kinds twenty per cent., one-fourth of them being ground-beetles and the others including June-beetles, blister-beetles, curculios, click-beetles, and plant-beetles. One bird had eaten twenty chinch-bugs, and others had eaten various soldier-bugs. Crane-flies had been occasionally devoured. "Considering these data with reference to the interest of the farm and garden," writes Professor Forbes, " Ave must admit the jjrobable eminent usefulness of this bird. Its great destruction of grasshoppers and of cutworms and other caterpillars, and the absence of all depredations other than the appropriation of scattered grains of corn (often picked, no doubt, from the droppings of stock), taken in connection with the fact that it eats only the normal average of predaceous insects, are. all strong indica- tions of valuable service rendered, with unusually few draw- backs. It supervises our grass-lands much more closely than the bluebird or the robin, and should be carefully protected from the shotgun and birds-nesting school-boy." THE ORIOLES, BLACKBIRDS, CROWS, AND JAYS. 107 Twenty-nine Wisconsin meadow-larks studied by Professor King had eaten forty beetles, including a May-beetle, weevil, tiger-beetle, and ground-beetles ; nineteen grasshoppers ; many caterpillars ; one dragon-fly, and a single thistle-seed. Ninety-nine per cent, of the stomach contents of thirty specimens from various places in New York, Pennsylvania, North Carolina, and Tennessee, shot during October and November and studied by Dr. C. H. Merriam, consisted of insects, including twenty-five caterpillars, fifty-seven grass- hoppers, and more than eighty beetles. The seeds of clover, wheat, oats, corn, and various weeds and grasses were also eaten to a slight extent. Eight Nebraska meadow-larks had eaten two hundred and thirteen locusts as well as locusts' e^s and many other insects. "The farmer cannot afford," writes Dr. S. D. Judd, "to dispense Avith the services of the meadow-lark, for it busies itself all summer eating grasshoppers and noxious insects, and when autumn comes varies its diet with rag- weed, pigeon-grass, and other weeds, until in December these noxious plants comprise twenty-five per cent, of its food." There has been much discussion concerning the economic status of the Common Crow. By some people its merits are believed to be greater than its defects : by others it is con- sidered an unmitigated nuisance. There seems to be no doubt that, on the whole, the crow is not a bird to be encouraged, although it is not desirable that it be altogether exterminated. It is a widely distributed si)ecies, occurring throughout the United States, though much more abundant iu some localities than in others. The birds are wary, having learned wisdom from experience, and it is very difficult to get within shooting range of them. The crime that is most commonly laid against them is that of digging or pulling up newly planted grains, such as wheat and Indian coimi, especially tlu* latter; in the Kash'ni Slates this lias leil to the almosf nnivtTsal use 168 BIRDS IN THEIR RELATIONS TO MAN. of scarecrows of some kind. The damage done in this way- is sometimes very great, often causing the loss of one-third of the crop, although, as a rule, the injury is slight. This seems to be an acquired habit, belonging to comparatively few of the crows. One Missouri observer reports that he once saw eight crows in his corn-field, two parents and six young. " One was pulling the corn, one standing idle, and six eating the grain after it was pulled up.*' Isolated fields and those near the nesting-sites are usually much more liable to ^ ^^^^ Jamty' ^' ' '1 1 ^ 4v<^ykif \i >,^ tiBBS^^^jir^ • .'I'-l ijiitt THE COMMON CROW {After WarrtH.) injury than others. Later in the season, when the corn is in the soft, milky stage preceding ripening, the crows again attack it, tearing the husks from the ears and picking out the kernels. In some parts of New England and Canada the crow is accused of serious injury to recently planted potato fields. When the plants appear above ground the birds pull them up to get at and devour the partially decayed tubers that were used for "seed.'" In the South rice and ])oa-nnts are said lo THE ORIOLES, BLACKBIRDS, CROWS, AND JAYS. 169 be also attacked, while in various regions injuries to small fruits have been reported. One of the most serious flaws in the character of the crow is his fondness for eggs and young birds, either in the poultry- yard or out of it. In some localities crows are more dreaded by the poultry-keepers than hawks, as they destroy young chickens before the latter are past the downy stage. The eggs of hens, ducks, and turkeys are also appropriated. Like the corn-pulling habit, tliis thieving seems to be confined to certain individuals, and it is done chiefly to get food for the nestlings. That the crow is an inveterate enemy of many of our wild birds there can be no doubt. The evidence in hand con- clusively proves that it robs the nests of the commoner thrushes, such as the wood-thrush, brown thrasher, and robin, as well as tliose of the orioles, blackbirds, sparrows, quail, grouse, woodpeckers, swallows, warblers, and otliers. Both eggs and young birds are taken. '' In all the dark history of the crow's relations to other birds," writes Professor Bar- rows, '' there is* nothing which can fairly be called a bright spot, and only here and there a record is found which serves to render the page a little less gloomy. One of the grains of comfort is found in the fact that in its wholesale attacks on other birds a few species suffer which are scarcely better than itself." Any claim to favor which the crows may have is })ased largely on its insect-eating proclivities. But the defi- nite knowledge as yet obtained goes to show that the crow can scarcely prove itself a philanthropist on this score. While the bird undoubtedly eats large numbers of grass- hoppers, the other elements of its insect food arc not of great ecoiK)mi(^ importance, consisting as largely of the so-called beneficial species as of the injurious ones. This is shown by the following table, which gives the economic results of a study, made at the Dejjarlinent of Agriculture, of the insect food of sixtv-six crows: 170 BIRDS IN THEIR RELATIONS TO MAN.

Others clami that it is useful as a scavenger, feeding on carrion. It is also known to feed largely on various wild berries, such as those of the Virginia creeper, dogwood, bayberry, red cedar, elder, wintergreen, pokeweed, smilax, poison-ivy, and poison- sumach. It scatters the seeds of these plants far and wide, and the fact of its thus aiding in the distribution of poison- ivy and poison-sumach has been considered one point against the bird. Professor Barrows has sununarized the evidence for and against the crow as follows : " (1) Crows seriously damage the corn crop, and injure other grain crops, usually to a less extent. (2) They damage other farm crops to some extent, frequently doing much mischief. (3) They are very de- structive to the eggs and young of domesticated fowls. (4) They do incalculable damage to the eggs and young of native birds. (5) They do much harm by the distrO^ution of seeds of poison-ivy, i)()ison-sumacli, and perhaps other noxious plants.

He is a thief, stealing the hunter's game, the traveller's supplies, eveu his very dinner before him. Worse than all, he is an assassin, a torturer without a heart, merciless. Young birds are tidbits for him. With bound- less audacity he assaults horses and mules, galled by their harnesses and reduced by continuous packing over rough trails, lacerating their raw flesh and sometimes even going so far as to put out their eyes. If people will have cage-birds, here is a proper victim. A criminal by nature, he may be confined without compunction. His odd and knowing ways make him an interesting pet, and after once becoming accus- tomed to a cage, captivity does not appear a hardship for him. Economically the magpie is a failure. The Blue-Jay is a resident over the whole of the United States east of the Great Plains. Its home is in the woods, though it makes frequent excursions to orchards and orna- mental trees about the farmstc^ad. These birds are seen to best advantage among the nut trees in autumn. Then is tin* tune of their harvest. From tre(^ lo tree they go in troops, calling in glee, swishing the branches, rattling down nnts, forcing an opening by well-directed blows of tluMr powerful bills through hard shells, or busily engaged in hoarding snp- plies in crevices for use in the coming season of want.

Sometimes a flock will develop a taste for corn, and do more 172 BIRDS TX THEIR RELATIONS TO MAN, or less damage as il stands in tlie field, but tliis is by no means chargeable to all blue-jays, as there are undoubtedly many that never tasted a kernel. In spring and summer, insects, fruit, and a variety of mis- cellaneous matter are eaten. The jay is cpite as unscrupulous as the crow, which it resembles in many ways. Birds' nests are occupied at the season when it is obliged to forage widely for supplies, and eggs and young are sometimes carried off and devoured. Just how prevalent this unfortunate habit is has not been determined, but there can be little doubt that individual jays, at least, do much damage in this manner. THE BLUE-JAY. {A/ler Bioloijkcd ISurvey.) An examination of two hundred and ninety-two stomachs, collected in every month of the year from twenty-two States and the District of Columbia, made by the Department of Agricultun^ at Washington, showed that })ractically three- fourths of tlie food was vegetable. Forty-two per cent, of the year's average was "mast," — a comprehensive term for nuts and large seeds of trees and shrubs. Corn was found in seventy-one stomachs and amounted to about eighteen per cent, for the year. The stomachs taken in autumn showed conclusively tliat these birds prefer nuts to corn. THE ORIOLES, BLACKBIRDS, CROWS, AND JAYS. 173 In spring more or less fruit is consumed. In March apples frozen on the trees amounted to thirty-two per cent. Fresh fruit is taken quite largely in June and July, averaging about thirty-five per cent, for the two months. Of this strawberries, currants, blackberries, and mulberries were the only cultivated species, and none of these were taken in much quantity. The insects eaten were mainly beetles, grasshoppers, and caterpillars. Most of the beetles belonged to the familes Carabidce and Scarabcekke. Grasshoppers and caterpillars are both eaten cjuite extensively. Wahuit caterjiillars (Thikina) are sometimes destroyed in great numbers. In this analysis only two stomachs contained traces of egg-shells of small birds, and only one, remains of young. In a few stomachs w^ere found remains of fish, salamanders, frogs, mice, and a shrew. Except in cases where blue-jays are actually engaged in depredations it is unwise to destroy them. As a rule, they are beneficial. HEAD OF PURPLE URACKLE. CHAPTER XV. THE FLYCATCHEKS, HUMML\(i-BlHDS, SWIFTS, AND NIGHT- HAWKS. THE FLYCATCHERS. To the naturalist who wanders much afield the Ph(ebe, or Pewee, is one of the dearest of feathered friends. For it is a familiar companion in the North from spring until autumn and in the South throughout the winter. It makes its home on almost every farm, so that tlie sight of it evokes in the mind of every one brought up in tlic country tender memo- ries of early associations. Nearly all of its food consists of insects, most of which are captured in tlie air. JN'rclicd upon an ex- Ijosed twig or a dead nmllein-stalk, the bird scans w ith eager eye the surrounding space, alert for any winged thing that may come within its range of vision. When a beetle or a moth flies by, the bird darts quickly towards it, snaps its ca- pacious beak, and the career of the insect is ended. Return- ing at once to its perch, the phoobe waits patiently for another morsel. Thus it spends its days. A careful examination of the contents of many phoebe stomachs by experts at Wasliington "showed that over ninety-three per cent, of the year's food consists of insects and spiders, while wild fruit constitutes the remainder.'' The 174 THE I'HCEBE. THE FLYCATCHERS. 175 insects are chieny of species injurious lo man's interests, so that tliese feathered friends are of <,TeaL utilily in reducin<^' the liordes of noxious pests. The nest of the phoebe is built by preference upon the timbers of a bridge, witli the murmur of running water just beneath. It is composed of mud and moss plastered against the side of the support. When it is completed the mother bird lays four or five white eggs, which are faithfully incubated until they hatch into hungry birdlings that keep the parents busy bringing food. The young are fed wholly witli insects and theu" allies, including chiefly moths, grasshoppers, ants, spiders, and similar creatures. The phoebe is so universal a favorite that it has not wanted champions wherever it is found. But the knowledge of its exceeding usefulness should win for it more friends, who shall encourage its increase in every way possible. For surely there can be no straining of the quality of mercy in protecting these feathered creatures : such mercy is thrice blessed, — for it blesses first the birds, second ourselves, and third our children and our children's children in trans- mitting to them undiminished Nature's heritage of man's allies. The KiNGBmo is noted for its pugnacious antipathy to hawks and crows, and is esteemed by agriculturists for this quality whicli makes it a veritable knight of the farm. H is familiar with mankind, makes its home in the orchard, and takes no pains to hide its nest. The protection it affords against marauding birds is not more important than its benefits as an insect destroyer. Ninety per cent, of its food consists of insects, including such noxious species as May- beetles, click-beetles, wheat and fruit weevils, grasshoppers, and leaf-hoppers. Bee-keepers liave made the claim againsl (lie kingbird fliat it is destructive to bees, but evidence furnished by dissections tends to prove that this damage is really of slight conse- 176 BIUDS IN THEIR RELATIONS TO MAN. quence. It is recorded of an Iowa apiarist that he suspected these birds of eating his bees and shot several near his hives, but when examined by an expert entomologist no bees were found in their stomachs. Of Iavo hundred and eighty-one stomachs opened by the Biological Survey, only fourteen contained honey-bees, fifty in all, forty drones, four workers, and six undetermined. The destruction of the drones was a benefit, and the few workers were more than compensated for by nineteen robber flies that had been eaten. Small fruits, such as elder-berries, blackberries, and wild cherries, make up ten per cent, of its food. In southern Louisi- ana it partakes of berries of the prickly ash and tobasco pep- l)ers and is regarded as a pest by pepper- planters. This spicy diet gives its flesh a p u n g e n t flavor which makes it sought for the table, and numbers are annually killed for market. The food of the young kingbirds consists almost wholly of insects, nearly half of it being crickets and grasshoppers when these are abundant. The other common flycatchers — the (iREAT Crested, the Least, and the Wood Pewee — appear to have feeding habits very similar to the phoebe and the kingbird, although, of course, woodland species find insects of quite ditferent sorts from those in cultivated spaces. THE KINGBIRD. {After Biological Sitrreii.) THE HUMMINC-IUIU) AND THE CHIMXEV-SW H"T. THK IirM.MI\(;-liIKl). Only one species — the llrmTHROAT — of the beautiful family of humming-birds {Trochilidce) occurs in the Northern States. This feathered sprite is rather common and may often be seen hovering before flowers, from which it extracts nectar and minute insects and spiders. Considerable discussion has taken place as to whether its food consisted mainly of insects or nectar : the relative proi)ortion of the two elements prob- ably Taries with the season and locality. When the sap of trees is obtainable, the birds appear to prefer it to any other food. They regularly visit trees perforated by yellow-bellied sapsuckers : Mr. Frank Bolles says that in the White Moun- tains of New Hami)shire, '• the humming-birds, at ' orchards' Avhere they are not molested by the woodpeckers, drink scores of times in the course of the long summer day. When not drinking they are usually perched on twigs a few yards from the holes, keeping their nervous heads w^agging from side to side while watching for intruders. In a few instances I have seen humming-birds perch upon the bark below the holes, in order to drink long without being forced to keep their wings moving while enjoying the sweet sap."^ The young are fed chiefly upon minute insects, such as gnats, ants, and small bees. According to Mr. William Brewster's observations, the young are fed by regurgitation. THE CHIMXEY-SWIFT. The swifts {Cypi Laeniiec for Iht- art 184 BIRDS IN THEIR RELATIONS TO MAN, either.

Seventeen AVisconsin specimens had eaten forty insect larvae, including twenty wood-boring grubs and three caterpillars, seven ants, four beetles, a chrysalid, one hundred and ten small bugs, and a spider, together with a few acorns and small seeds, and a little woody fibre apparently taken by accident along with tlie grubs. Three-fourths of the food of one hundred and forty specimens examined by the Department of Agriculture con- sisted of insects. Nearly one-fourth consisted of ants, taken chiefly from those which are attending aphides or burrowing in wood. Audubon states that in autumn these woodpeckers eat poke-berries and wild grasses. Mr. W. E. Cram observed one of these birds opening the seed cases of mullein in Au- gust. " I found that seed vessels that contained grubs were brown, while those on the same stalk free from them were still green, and observed that the woodpecker only opened the brown ones." Dr. D. S. Kellicott has reported that the downy woodpecker has been ''most industrious in Columbus, Ohio, in boring for the larvae of the maple aegerian," a pest of shade-trees. Mr. A. W. Butler has " often found them feeding upon sunflower seeds, of which they are very fond." The young birds are fed with insects, ants forming a large percentage of their diet. The only injur^^ that can be charged to the account of this I)ir(l is that of spreading the seeds of poison-ivy, the berries of which it eats. The seeds pass through the body unharmed as to their germinating qualities. Probably this is a chief reason why these plants are so generally found growing around the bases of trees. The FLicKEFi, although one of the woodpeckers, has habits quite different from the majority of its tribe. Instead of drilling holes in trees for a living, it gets most of its food from the ground. Its structure, esix'cially Ihat of ils bill, is nioditicd 186 BIRDS IN THEIR RELATIONS TO MAN. to suit its peculiar habits. Tlie ordinary woodpecker's bill is shaped like a chisel at the tip, but that of a flicker is like a l)i('kaxe. It has the same long, extensile tongue which charac- terizes most of the woodpeckers. This is used for catching small insects, by being thrust out covered with sticky saliva and entangling them. Larger insects are grasped by the bill. Flickers relish fruit as much as robins do. The two species are usually associated when the berries of the sour-gum and black-cherry trees are ripe. In winter flickers eat the berries of Ampelopsis. Nearly half the flickers' diet consists of ants. HEAD OF FLICKEK. In two hundred and thirty stomachs examined at Wash- ington fifty-six per cent, was animal matter, thirty-nine per cent, vegetable, and five per cent, mineral. Two of them contained over three thousand ants each. Other insects were beetles {Coleoptera)^ bugs (Hcmipfera), grasshoppers and crickets (Orthoptera)^ caterpillars {LrphJopfera), May-flies (Ephemerida), and white ants {Isoptera).

Instead of delving in wood, he sits on a post or a telegraph-pole or similar point of vantage, taking beetles, grasshoppers, and other insects which come along or are seen on the ground. At times he darts out for flying insects and captures them on the wing. He is fond of corn and nuts. In autumn these birds store nuts in all sorts of crevices for future use. It lias been l';| }i''iM;'V f y. .y wm observed that in years when there are many beechnuts, red- headed woodpeckers spend the winter in the Northern States, except New England where they are rare. About half the food taken by this species is anunal and half vegetable. Beetles are eaten oftener than any other order of insects, forming about a third of the total food. Among these beetles are many carabid and tiger beetles, whieli, ])eing carnivorous, are more or less useful. There are other com- 188 BIRDS IX THEIR RELATIONS TO MAN. plaints against tliis woodpecker besides that of killing useful beetles. It sometimes devours cultivated fruits, — blackberries, strawberries, cherries, apples, pears, etc., — thereby raising the farmer's ire, and at times robs birds' nests of their young. On the other hand, many of the beetles and other insects are harmful and most of its vegetable food is valueless.

One of the most notable illustrations of the value of wood- peckers has been l)rouglit to light through the investigations of spruce insects in the Northeast by Dr. A. D. Hopkins, forest entomologist of the United States Department of Agri- culture. Dr. Hopkins found that great damage was being THE WOODPECKERS, KINGFISHERS, AXD CUCKOOS. 189 done by the spruce-destroying bark-beetle {Bendrodonus piceaj)erda), but that its work was being largely checked by woodpeckers, probably chiefly the Arctic Three-toed Wood- pecker and the Banded Three-toed Woodpecker, as these species come from the far Xorth in winter and live in northern New England in numbers. Dr. Hopkins writes: "Woodpeckers are the inost important enemies of the bark- beetle, and appear to be of inestimable value to the spruce- timber interests of the Northeast. Indeed, I feel confident that in the many hundreds of infested trees examined, at least one-half of the beetles and their young had been destroyed by the birds, and in many cases it was evident that even a greater proportion had perished from this cause alone. '- Estimating one hundred beetles to the square foot of bark in the average infested tree and an average of sixty square feet of infested bark, it is possible for each tree to yield an average of six thousand individuals, one hundred trees six hundred thousand, and so on. It is therefore plain that if one-half or two-thirds of tliis number are destroyed by the birds and other enemies, the amount of timber the remainder can kill will be lessened. This is all the more apparent when it is remembered that it is only when the beetles occur in great numbers that they can overcome the resistance of the living trees." In California, however. Dr. Hopkins has found the wood- peckers to be in some respects of doubtful utility in their relations to forest insects. There certain clerid beetles and other enemies of bark-borers are abundant, and are especially exposed to the attacks of woodpeckers. Tlie result is that they are eaten to a large extent and so are prevented from killing the bark-beetles. The Yellow-bellied Woodpecker, or true Sapsucker, either in the typical or a varietal form, occurs throughout the Ignited States. Although seldom an abundant species, it is rather common within its range. The structure of its tongue dilfers 190 BIRDS IN THEIR RELATIONS TO MAN. from that of its congeners : it is only slightly extensile and is not adapted for penetrating the channels of and dragging forth wood-boring larvae. Consequently these pests are seldom found in its food. Its usual diet appears to consist of insects and berries of A^arious sorts, together with the sap and more or less of the inner bark (cambium) of trees. Like the flicker it takes great numbers of ants, the other insects eaten including beetles, crane-flies, grasshoppers, caterpillars, and bugs. Fifteen out of thirty Wis- consin specimens had eaten nothing but ants. Of berries, wild grapes and dogwood-berries are de- voured. There can be no question that the yelloAv-bellied Avoodpecker habitually feeds upon the sap of trees: the testimony of naturalists and fruit-growers in many widely separated localities is conclusive on this point. To obtain the sap the birds make horizontal series of punctures in the bark of many trees ; these holes extend through the bark and slightly into the wood. They are deeper than those made by the downy woodpecker and run horizon- tally around the tree, a half-inch or more apart. Two or more series, one above the other, are usu- ally made in the trunk of the chosen tree. The sap oozes into these holes and the birds revisit them constantly to suck it up, just as the owner of a sugar-orchard visits his pails to gather the sap from the maple- trees. During recent sunnners we have repeatedly seen these birds thus visiting the hundreds of punclures they had made in a row of English wliite birches along the border of Dart- mouth College park. The woodpeckers w(^re by no means the only visitors attracted by the flowing sap : humming-birds, hornets, wasps, flies, and ants were there in abundance.

THE OWLS. 199 owls prefer heavy woodlands or wooded swamps — such as the cypress swamps of our South Atlantic regions — where they may be found much oftener than in more open regions. The ScREECH-OwL is one of the best-known and most abundant of the grou}) : it inliabits all parts of the United States, and is found throughout southern Canada. It is one of the most beneficial birds of prey and deserves the encour- agement and protection of farmers everywhere^ Its food is varied, consisting of insects, crawfish, frogs, fish, lizards, small birds, and es- pecially mice, of which ' it destroys enormous numbers. In summer insects form a large part of its fare : an owl in captivity has shown a fondness for cater- pillars, and the stomachs of two examined in New Jersey were full of full-grown nymphs of cicadas or harvest- flies. In warm win- ter weather it stores up in its hiding-place mice, moles, and similar creatures to serve as food during more inclement periods. The only bad habit attributed to it is that of occasionally catching small birds, but since the introduction of the English sj)aiTow this trait is favorable to the owl's usefulness, since it is known to prey to a considerable extent upon these unwelcome immi- grants, in the nest of a screech-owl at Columbus, Ohio, were SCREECH-OWI^. {After liioloijical Siirvei/.) 200 BIRDS IN THEIR RELATIONS TO xMAN. found the bodies of two English sparrows and one field- mouse. The Long-eared Owl is a common and widely distributed species in North America. In some parts of the Southwest it is considered the most abundant of the owls ; and the tes- timony of all competent observers points to the fact that it is one of the most beneficial members of its family. That its food consists very largely of mice is shown by the fact that out of one hundred and seventy-six skulls taken by Dr. Fisher from beneath the roosting-site of one of these owls, one hun- dred and thirty-seven were of mice of various species, while twenty- six were of shrews, the remaining thirteen consisting of eleven sparrows, one warbler, and one bluebird. The same observer found that out of one hun- dred and seven stom- achs from many parts of the country eighty- four contained mice ; iive, other small mam- mals ; sixteen, small birds, one being a quail ; while one contained insects and fifteen were empty. Dr. B. H. AVarren found that twenty-two out of twenty-three Pennsylvania long-eared owls had eaten only mice, while the twenty-third one had taken beetles and a small bird. The remains of eight field-mice were taken from the stomach of one specimen by Mr. Townend Glover; wliilc in Oregon AMERICAN LONG-EARED OWL. {After Biological Sxrvei/.) THE OWLS. 201 Captain C. E. Bendire found the food to consist principally of mice and the smaller rodents. The long-eared owl commonly breeds in trees, using the deserted nest of a hawk or crow for the purpose. From three to six eggs are deposited. It is a nocturnal bird, hiding in groves of evergreens and other sheltered retreats during the day. There are a number of very small owls in the United States. In the South and Southwest are found two species of pygmy owls, usually less than seven inches long; while in Arizona occurs the little Elf Owl, the smallest species of its family in North America. These owls feed upon insects, the smaller mice, and occasionally small birds. In the Eastern and Northern States the smallest owl is the Acadian or Saw-Whet Owl, a bird usually about eight inches long, which is occasionally found from Canada as far south as North Carolina. Its nest is built in hollow trees, generally in holes made by flickers, during early spring. Its food consists chiefly of mice and shrews, Avith the addition of insects in summer, and an occasional sparrow or other small bird. The young are fed chiefly upon mice of various kinds and small birds. The Great Horned Owl is found over almost the whole of North America. In strength and ferocity it lias no equal among our rapacious birds. Of all the owls which we have, it is the only one distinctly harmful. During the day it keeps very closely hidden, more to escape i)ersecution from crows and other birds that delight to toriiient it than because the light of day is painful to it. As a matter of fact, there is scarcely a keener-visioned creature in the A\oods than this owl, in spite of the general impression that it cannot see well when the sun shines. Its food consists mainly of mammals and birds, though it sometimes catches insects. A sjxM'imen examincMl by us had eaten a ('atrr|>illar (Kachs Inijxrid/is) in afldition to a cliickcn. 202 BIRDS IN THEIR RELATIONS TO MAN. Nocturnal mammals are frequent victims. Four out of every five of these owls that are brought in have been scented by a skunk. Two nests that have come under the writers' obser- vation both had the remains of skunks upon them beside the young. Rabbits are caught in large numbers. Musk-rats, rats, mice, and shrews are on the regular bill of fare. Many birds are snatched from their roosts and borne away by this HEAD OF GREAT HORNED OWL. literally '' silent messenger." The ruffed grouse is often taken. Farmers who carelessly allow their turkeys, chickens, or guinea-fowls to roost on fences and trees are frequently made to repent.

Of one hundred and twenty- seven stoniaclis of the great horned owl tliat were examined at the Department of Agriculture, thirty-one contained poultry or game-birds ; eight, other birds ; thirteen, mice ; sixty-five, other mammals ; one, a scorpion ; one, fish ; ten, insects ; and seventeen were empty. In the arctic regions of North America the beautiful Sxowy Owl is a rather conmion species. It is one of the largest members of its family, often being more than two feet long. In winter it is occasionally found in the Northern States, especially in New England, but during summer it remains in the far North. The summer food of this bird consists very largely of the small rodents known as lemmings, which abound in most arctic regions. These and related rodents seem to be the fa- vorite food except in winter, when other animals, including the ptarmigan and arctic hare, are eaten. During its winter visits to southern Canada and the Northern United States, it lives upon rabbits, rats, mice, and A^arious birds. It is expert in catching fish, which form a favorite article of food. The snowy owl is so rare in our country that it has little economic importance, but it probably deserves to be letl un- molested when it visits us. The Burrowing Owl is found in some parts of Florida, but is best known on the Great Plains, where it is abundant, living in prairie-dog towns and the burrows of ground- squirrels. Its food is varied, but consists chiefly of rodents, young rabbits and prairie-dogs, chipnumks, goph<'rs, mice, and shrews. It also feeds on grasshoppers, crickets, b(M^tl(*s, scorpions, and centipedes. In localities where prairie-dogs ^ Birds of Connecticut, 1877, p. 97. l>04 mnm ix their relatioxs T(j man. are plentiful, the young' ones form a large share of the food of this species.

They very rarely attack poultry or birds of any kind, and unques- tionably deserve the protection of the liusbandman. Of the various birds to which the name hen-liawk is occa- sionally applied it is least deserved by the Rough-legged Hawk. All the evidence obtainable goes to show that this species is not in any sense a hen-hawk, but that instead it is a mouse- hawk, feeding almost exclusively upon meadow-mice. Forty out of forty-nine stomachs examined at the United States Department of Agriculture contained mice, while five of them contained such small mammals as shrews, gophers, rabbits, and weasels, one contained nisects and a lizard, and four were empty. No poultry or birds of any kind were found. Similar testimony from many other sources has been pub- lished ; in Massachusetts hundreds of these birds were killed along the Connecticut River, and all the stomachs examined contained only meadow-mice ; in Oregon, Utah, and Nebraska fielcl-mice are reported as the staple chet, while cotton-tail rabbits, gophers, and other annuals are also included in the bill of fare. The rough-legged liawk is a northern bird in sunnner, as a rule visiting the United States only in winter. It is said generally to keep south of the snow line in order to cai)ture its favorite prey more easily. It hunts in the twilight, watching for victims from some low perch or slowly flying over meadows and marshes it breeds in the far North. The typical form of the Red-shouldered Hawk is common in the Eastern States and closely related rac(>s are found in the South and West, though the bird is absent from Ihe Great Plains re-ion. 1( breeds throughout its range, tlie nest being built in early s{)ring in the upi)er branches of some tall tree, and a brood of from three to live young being reared.

It takes a great variety of food : two hundred and twenty specimens, taken during every month of the year in thirteen widely separated States, Territories, and Provinces, were ex- amined by Dr. Fisher. Two of these contained chickens, with a fair probability that they had not been killed by the hawk ; one, a quail ; twelve, other birds, including a flicker, meadow-lark, screech-owl, Carolina dove, snow-bird, sora rail, robin, crow, and various sparrows ; one hundred and two, mice, including the house, pine, field, white-footed, red-backed, and meadow varieties, chiefly the latter; forty had eaten other mannnals, among which were the musk-rat, chipmunk, skunk, rabbit, opossum, and various shrews ; twenty contained rep- tiles, including ribbon, water, striped, garter, and green snakes, as well as lizards ; thirty-nine liad eati^n batrachians, princi- pally frogs, though toads, tree-frogs, and salamanders were also present ; ninety-two contained insects, the most important ele- ment being grasshoppers and crickets, although large caterpil- lars, beetles, white grubs, katydids, cicadas, and cockroaches were also present ; sixteen of the hawks had eaten spiders ; seven, crawfish; one, earthworms; two, offal; three, fish; Avhile fourteen stomachs contained nothing. Such a showing as this ought to convince any one of the general beneficence of a bird Avhose food consists of sixty-five per cent, of mice and not more than one per cent, of poultry. The typical form of the Red-tailed Hawk is found in eastern North America, ranging Avest as far as the Great Plains, while five closely allied geographical races occupy the western portion of the continent from Central America northward. It is one of our larger hawks, usually measuring nearly or quite two feet in length and having a wing expanse of four or five feet. It is a migratory species, often travelling in large flocks and spending the winter in the Central and Southern States. In many regions it is common and is often persecuted as a hen-hawk. THE HAWKS, KACIJIS, KI'IKS. A.\l> V^TLTURE^ 2()!l Our knowledge ul" llie feeding: luibils of lliis spccu'S is unusually complete. Besides the isolated observations of a large number of competent observers, we have tlie results of the special studies of Dr. B. H. Warren, in wliich the con- tents of one hundred and seventy-three stomachs were ex- amined, and Dr. A. K. Fisher, who studied five hundred and sixty-two stomachs from twenty-six widely separated States, Territories, and l^rov- inces, ranging from Ontario to Florida and Massachusetts to Califor- nia. Dr. Warren found mice in one hundred and thirty-one of the one hundred and seventy- three stomachs he ex- amined, while six of them contained rabbits ; three, red squirrels ; two, skunks ; and eigh- teen, small birds. Poul- try was found in four specimens, insects in three, snakes in three, and carrion in four. Thus, less than ten per cent, of the birds had eaten poultry. Dr. Fishers results as to ponltry were similar ; fifty-four out of the five hnndred and sixty-two specimens contained i)onltry or game-birds. Various other birds, as the robin, mourning- dove, (TOW, shore-lark, king-rail, meadow-lark, oriole, blue- bird, grackle, screech-owl, and several species of sparrows, were found in iifty-one stomachs. Mice — including the house, meadow, pine, white-fooled, harvest, and (/oo})er*s mice — had 14 RED-TAILEH HAWKS. {After Biolvyicul Hdn-eii.) 210 BIRDS IN THEIR RELATIONS TO MAN. been eatcii by two hundred and seventy-t%dit of the birds ; while other small mammals — as the gray, red, and rock squir- rels, the gray, striped, and pouched gophers, chipmunks of various species, the musk, cotton, kangaroo, and common rats, three kinds of rabbits, as well as shrews and skunks — were found in one hundred and thirty-one stomachs. Frogs, toads, lizards, and snakes had been eaten by thirty-seven of the hawks ; insects, chiefly grasshoppers, by forty-seven ; craw- fish by eight ; centipedes by one ; and otfal by thirteen : while eighty-nine of the stomachs were empty. That this hawk on the whole does considerably more good than harm there is no doubt, but the balance in its favor is not so great that it is worth while to extend to it too much protection in thickly settled conniiunilies. There are three species of hawks wliose bill of fare consists principally of birds and poultry. They are the sharp-shinned hawk, Cooper's hawk, and the American goshawk. To these three birds is largely due the oblocjuy which rests upon the family as a whole. They are all trindy built birds, strong of wing and foot, and inveterate enemies of other birds. Their only redeeming features are that they occasionally capture a rabbit, a mouse, or an English sparrow. The SiiARP-smxxED Hawk is the smallest of the three, measuring from ten to fourteen inches in length. It is com- mon and widely distributed, breeding throughout the United States and British Provinces, and migrating with the changing seasons. It passes the winter as far north as the fortieth parallel. More than any other hawk this species seems to feea on birds. Dr. Fisher examined one hundred and seven stomachs which contained food ; in six of them were the remahis of poultry or game-birds and in ninety-nine of them were the remains of other birds ; all but two had eaten birds of some kind. Mice had been eaten by six of them and insects by five. The variety of birds taken was surprising; besides the young or half-grown tiiickens there were evidences THE HAWKS, EAGLES. KITES, AM) \ I LTl IIKS. •211 of the presence of the quail, robin, oriole, swilt, bluebird, downy woodpecker, flicker, cow-bird, mocking-bird, cat-bird, oven-bird, herniit-thrnsh, mourning-dove, chickadee, snow- birds, and various wrens, warblers, buntings, and s})arrows, including the English variety of tlie latter. No bird witli such a record deserves protection. Cooper's Hawk may be considered a larger type of I he sharp-shinned species. It measures from fourteen to tweiily inches in length, is found throughout North iVmer- ica as far north as the British Provinces, mi- grates south to spend the winter, and is an invet- erate enemy to poultry, game and other birds. Of ninety-four food- containing stomachs ex- amined by Dr. Fislier poultry or game-birds were found in thirty- four and other birds in fifty- two stomachs. Small mammals, including two mice, one cotton-rat, three chipmunks, one red squirrel, one gray squirrel, one ground- squirrel, and one rabbit, had been eaten by eleven of the hawks. Two others had taken insects, one a frog, and three had eaten lizards. The game- birds destroyed included pigeons, quail, and niO'ed grouse, and on the list of other birds one finds the cliewink, purple grackle, meadow-lark, flicker, inithalch, hermil-thrnsli. dove, robin, snow-bird, nioiiniiiig-dovc, and \ari(nis warblei's and sparrows. COOPER'S HAWK. (Afh-r r.iohxjiral Snrreii.) 212 BIRDS L\ THEIR RELATIONS TO MAX. This species is, as Dr. Fisher remarks, " pre-eminently a chicken-hawk. Its devastations in this direction are much greater than lliose of all the other hawks and owls together, with the possible exception of the sharp-shinned hawk, which attacks much smaller chickens." This bird is also learning to add the English sparrow to its bill of fare. The Goshawk is not a common species in the United States, although in winter it is occasionally found. It is a northern bird, occurring frequently in the British Provinces, where it breeds. It feeds largely on good-sized birds, such as chickens, ruffed grouse, cjuail, and mourning-doves, as well as on rab- bits, squirrels, mice, and sometimes the larger insects. It can scarcely be ranked as a beneficial bird in cultivated regions. It is fortunate that the Duck-Hawk is a rare species, because it is a savage bird, extremely destructive to other birds of many kinds. It is a powerful hawk, of good size, our form being simply a geographical race of tlie famous peregrine falcon of Europe. As its common name implies, it feeds largely on water-fowl, and is seldom found far away from the coast or the neighborhood of large bodies of water. When a pair breed in tlie vicinity of a i)oultry yard, — a rare event, — the chickens are liable to suffer severely. Among its other feathered victims one linds the meadow- lark, robin, cat-bird, mourning-dove, gray-cheeked thrush, and various warblers and sparrows. In Florida it feeds largely upjn the coot, enormous numbers of which still inhabit the inland lakes. At times it is very destructive to terns along the Atlantic coast. The beautiful Osprey, or Fish-Hawk, is of chief interest on account of its relations to the bald eagle, which so persistently robs the osprey of its prey in nud-air. The fish-hawk is chiefly a bird of the shore-line, Avliere it finds its food abundant. The Marsh Hawk, sometimes also called the Marsh Har- liiKii. inhabits almost the Nvliole of Xoi'lli Ainei-icji. bi'eediii'^ THE HAWKS. EAGLES, KITES, AND Vri/n^RES. 218 from Cuba to Alaska, It is most abundant in the jjrairie States. The nest is placed upon the ground in marshy situ- ations, wliere grass and sedges help conceal it. From four to six young are reared in each brood. This i.s one of the most useful of the hawks and deserves man's protection. '* Its food/' writes Dr. Fisher, " consists largely of small rodents, such as meadow-mice, half-grown squirrels, rabbits, and ground-squirrels. In fact, so extensively does it feed upon the last-named animals, that the writer rarely has examined a stomach from the West which did not contain their remains. In addition to the above, it preys upon lizards, frogs, snakes, insects, and birds ; of the latter, the smaller ground-dwelling species are usually taken. When hard pressed it is said to feed on otial and carrion ; and in spring and fall when water- fowl are abundant it occasionally preys upon the dead and wounded birds left by gunners.'' The stomach of a speci- men shot at Hanover, New Hampshire, in 1892, Vshen grass- hoppers were very abundant, which we examined, was full of these insects, showing that the bird was doing what it could to check the outbreak. In the Southern rice-fields these birds do good service in scaring away the flocks of bob- olinks. The marsh hawk is the farmer's friend, and its rare visits to the poultry-yard may well be excused on account of the enormous number of vermin it destroys. THE EAGLES. Bald Eagles are usually seen about the coast and larger inland waters, where they are able to find a supply of such food as best suits their taste. In the North they live almost exclusively upon fish, show- ing little or no regard for quality or condition, generally de- vouring any sort of fish that may come in their way, and are seemingly as well satisfied with a half-decayed subject washed up by the waves as with one freshly killed. In the Southern States, where water-fowl congregate in vast numbers during 214 BIRDS IX THEIR RELATIONS TO MAN. the winter months, tlieir food relations are somewhat modified, as is indicated l)y the fohowing extract, written by Dr. AMIliam L. Ralph and published in Bendire s " Life Histories of North American Birds." Speaking of a community of bald eagles in the vicinity of Merritt Island, he says : " These eagles seem to breed earlier than those in other parts of Florida, due no doubt to the immense number of vrater-fowl, especially coots [Fulica americana?)^ that frequent this vicinity during the winter, and which form the principal part of their food, tliough they will sometimes condescend to eat fish, like their more northern brothers and sisters. I have often seen them catch wounded birds, and I visited one nest that contained in addition to two well-grown young birds the remains of thir- teen coots and one catfish." Tlie Golden Ea(;le inhabits mountainous districts through- out the country, though it is more common West than in the East, where it is rare, owing to the denser population. It preys on grouse, ducks, hares, ground-squirrels, and other creatures of similar size, and occasionally troubles sheep-owners by carrying off young lambs. Sometimes it eats carrion, but probably only when pressed by hunger. The thrilUng stories told of the fierceness of this eagle are not credited by those who have invaded its nests ; yet its power is unquestioned. An instance is recorded in which one throttled and killed a black-tailed deer that had been (Tip])led by a hunter. Jf this were an abundant species, it would plainly be a harmful one; but, owing to ils scarcity, its depredations are generally insignificant. THE KITES. The kites are a branch of the hawk family especially noted for the ease and elegance of their flight. The commonest and most widely diffused species is the Swallow-tailed Kite, which has a geographical range from Pennsylvania to Minne- sota and southward. Six stomachs of this kite opened by THE HAWKS, EAGLES, KITES, AND VULTURES. 215 Dr. A. K. Fisher showed sixty locusts and live other insects in one, sixty-nine locusts and three other insects in another, and seventy-five locusts in a third. Lizards were found in two and a tree-frog in one. All contained insects — wasps, beetles, and grasshoppers being among tliem. Aughey reports of three stomachs that two of them contained sixty and sixty- nine locusts respectively, while the third contained seventy- five other insects. All the evidence tends to prove the swallow-tailed kite to be harmless at least and generally beneficial. Two other species, the white-tailed and Mississippi kites, have practically tlie same bill of fare, which besides the animals above noted is sometimes varied with snakes and mice. THE BUZZARDS. No birds are more familiarly known throughout the Southern States than the Turkey-Buzzard and the Black Vulture or Carrion Crow. These birds may be seen at all hours of the day sailing through the air in majestic circles or lazily resting on stumps or trees after a feast of their filthy food. They perform an important service as scavengers, disposing of all sorts of animal matter tliat would pollute the air. On this account, they are seldom molested by man and in some States are protected by law. They devour both fresh and putrid meat, and in many localities save the butchers the trouble of disposing of the refuse of the abattoir. They are known sometimes to capture live snakes and to attack helpless animals of many kinds. Along the sea-shore they feed upon dead fish cast up by the waves, and Audubon re- ports having observed them in the Florida Keys sucking the eggs and devouring the young of herons and cormorants. As another offset to the good tliese birds do, mention should be made of tlir fact that Mr. E. B. Williamson has suggested that they arc '• doubtless an important factor in IIk- sj)read of some diseases, — liog cjiolera, for example.'' 216 BIRDS IN THEIR RELATIONS TO MAN. It was formerly supposed that these birds discovered their food through the sense of smell, but a number of experiments by Audubon seem to prove conclusively that they depend upon sight rather than smell. In one of these experiments "a dead hare, a pheasant, and a kestrel, together with a wheelbarrow full of offal from the slaughter-pens, were de- posited on the ground at the foot of my garden. A frame was raised above it at a distance of twelve inches from the TniKEY-nrz/. {After lirch ARDS. earth ; this was covered with brushwood, allowing the air to pass freely beneath it so as to convey the efiluvium far and wide." Although left for nearly a month, with hundreds of vultures passhig over it daily, none of them discovered its presence. Anotli(>r time a perfectly dry stuffed deerskin was placed in a field, and inunediately attracted the vultures, which were of course unable to get any food. To test still further whcflici' llic bii-ds wciv allractrd by sight alone, ''a THE HAWKS, EAGLES, KITES, AND VULTURES. 217 coarse painting on canvas was made, representing a sheep skinned and cut open. Tliis proved very amusing. No sooner was the picture placed on the ground than the vul- tures observed it, alighted near, walked over it, and some of them commenced tugging at the painting. They seemed much disappointed and surprised, and after having satisfied their curiosity, flew away. This experiment was repeated more than litty times, with the same result." In other cases pieces of meat were placed beneatli tables and other pieces li# THE BLACK ^^TLTURE. ( Afler lirehm. ) on top. Tiie vultures would eat those in sight, but made no attempt to reach those just beneath their noses. The way in which vultures from far and wide rapidly con- centrate on a dead animal is explained by Audubon by the fact that, when the first discoverer pounces down upon its prey, the aclioii is seen and uiidershxxl ])y others in the vicinity; these lly immediah'ly to the spot. As they start tliey are seen by others, which in turn signal to more dis- tant birds, so that in a verv short time the vultures for miles 218 BIRDS IN THEIR RELATIONS TO MAN. around are aware that something in the shape of food has been found. The turkey-buzzard is a summer and winter resident throughout the United States as far north as tlie latitude of 40 degrees, and occurs in sunniier still farther north. F'or instance, it is abundant throughout the year in southern Illinois, and is sometimes seen in summer in northern Illinois. It is a more graceful bird than the carrion crow. In tlie breeding season each female lays two eggs on the ground or in a hollow tree or stump. The black vulture is darker colored than the turkey- buzzard and the feathers extend farther up on the back of the neck. Its nesting habits are similar to those of the other species. It is not commonly found so far north as the turkey-buzzard, although like that bird it is abundant in Central and South America. These birds both belong to the family Cathartidce, which is composed of the American vultures. The only other member of the family occurring in the United States is the Californian condor, a large bird found on the Pacific coast with habits similar to those of the turkey-buzzard. CHAPTER XIX. THE PIGEONS, GROUSE, AND SHORE-BIRDS. THE PKJEONS. Most educated Americans are familiar with accounts of the enormous numbers of Passenger Pigeons which formerly in- habited many of our States. Some of the stories seem almost incredible, but there can be no doubt that they are substantially true. Audubon's graphic description is well wortli quoting in this connection. "Let us now inspect the places of nightly rendezvous. One of these curious roosting places on the bank of the Green River in Kentucky I repeatedly visited. It was, as is always the case, in a portion of the forest where the trees are of great magnitude and where there was little underwood. I rode through it upward of forty miles, and, crossing it in different parts, found its average breadth to be rather more than three miles. My first view of it was about a fortnight subsequent to the period when they had made a choice of it, and I arrived there two hours before sunset. Few pigeons were to be seen, but a great number of persons, Avith horses and wagons, guns and ammunition, liad already established encampments on the borders. Two farmers from the vicinity of Russelsville, distant more than a hundred miles, had driven upward of three hundred hogs to be fattened on the pigeons which were to be slaughtered. Here and there the people em- ployed in plucking and salting what had already been procured were seen sitting in the midst of large piles of these birds. The dung lay several inches deep, covering the whole extent of the roosting i)lace like a bed of snow. Many trees I observed were broken off at no great distance from the ground ; and the branches of many of the largest and tallest had given 219 220 BIRDS IN THEIR RELATIONS TO MAN. way, as if the forest had been swept by a tornado. Every- thing proved to me that the number of birds resorting to this part of the forest must be immense beyond conception. As the period of their arrival approached, their foes anxiously prepared to receive them. Some were provided with iron pots containing sulphur, others with torches of pine knots, many with poles, and the rest with guns. The sun was lost to our view% yet not a dozen had arrived. Everything was ready and all eyes were gazing on the clear sky which ap- peared in glimpses through the tall trees. Suddenly there burst forth a general cry of ' Here they come.' The noise wiiich they made, though yet distant, reminded me of a hard gale at sea passing through the rigging of a close-reefed vessel. As the birds arrived and passed over me, I felt a current of air that surprised me. Thousands were soon knocked down by the pole men. The birds continued to pour in. The fires were lighted, and a magnificent as w^ell as wonderful and almost terrifying sight presented itself. The pigeons arrived by thousands, alighted everywhere, one above another, until solid masses as large as hogsheads were formed on the branches all around. Here and there the perches gave way under the weight with a crash, and falling to the ground destroyed hundreds of the birds beneath, forcing down the dense groups with which every stick Avas loaded. It was a scene of uproar and confusion. I found it quite useless to speak or even to shout to those persons who were nearest to me. Even the reports of the guns were seldom heard, and I was made aware of the firing only by seeing the shooters reloading. " No one dared to venture within the line of devastation. The hogs had been penned up in due time, the picking up of the dead and wounded being for the next morning's employ- ment. The pigeons were constantly coming, and it was past midnight before I perceived a decrease in the number of those that arrived. The uproar continued the whole night ; and, as I was anxious to know to what distance the sound reached, THE PKiEUXS, GROUSE, AND SHORE-BIRDS. 221 1 sent off a man accustomed to perambulate the forest, who, returning two hours afterwards, informed me he had heard it distinctly when three miles distant from the spot. To- wards the approach of day the noise in some measure sub- sided. Long before objects were distinguishable, the pigeons began to move off in a direction quite different from that in wliich they arrived the evening before, and by sunrise all that were able to fly had disappeared. The bowlings of the wolves now reached our ears, and the foxes, lynxes, cougars, ---LUL.

The food of the passenger pigeon is almost wholly of a vegetable nature, although occasionally a few insects are eaten. Its usual diet consists of acorns and other nuts, to- gether Avith seeds and grains. Even the young are fed upon beechnuts. In the United States the passenger pigeon is now practically an extinct bird, the ruthless persecution it has en- dured having led to this result. The Mourning or Carolina Dove is a beautiful bird whose plumage and habits entitle it to high consideration. It is vegetivorous, but seems to feed more freely on the seeds of Aveeds than on cultiA^ated grains. Professor King took four thousand and sixteen seeds of pigeon-grass (Setaria) from the stomach of a single bird, Avhile from that of another seA^en thousand five hundred seeds of oxalis have been taken. The young are fed Avith the regurgitated vegetable food of the adult. The Band-tailed I'igeon i^ColuniJxi /(txc'uitd), Avliich ranges AvestAvard froju the Rocky Mountains and southAvard through Mexico, is about the only pigeon that Ave noAv have Avorthy to be called game. It is sought by sportsmen both for its flesh and for its gamy (pialities. Its food consists of grain, berries and other soft fruits, and buds of certain trees, notably (^f balsam-})oplar. THE PARTRIDGE AND GROUSE. The Bob-White, or Quail, is found from Minnesota to Texas and eastAvard. It is favorably regarded by epicures and gunners and deserves the good Avill of those interested in agriculture, it lives in fields and i)astures and during the summer feeds largely on insects. Colorado i)otato-beetles are frequently eaten : one hundred and one of these pests have been taken from the stomach of one bird. Army-worms are also devoured. When insects are not plentiful, vegetable matter, Avhich is ahvays taken in greater or less quantities, becomes the staple form of diet. This includes grains, seeds, THE liilROXS. (iliOrsK.

Of two taken in New Hampshire in the winter when the ground was covered with snow, and examined by us, one had eaten seven oats, ten barberries, one poison-ivy seed, and some bits of green leaf that were not determined ; the other had eaten twenty-five oats, twelve barberries, seven smaU seeds, and ^ -' .^ «* n #■ -■'. ■ " ^m^^Mi m^*,- •Vx^' .,.7 ^ w^yw^w THE BOK-WHITE OR QlAIL. nine leaves of white clover. The oats had evidently been taken from liorse droppings in the road near by. According to the studies of the DepartnuMit of Agriculture, "seeds of rib-grass, tickfoil, and berries of nightshade are sometimes eaten, and pigeon-grass and smartweed are freijuently con- sumed in large quantities. The amount of grain food in the stomachs thus far examined is surprisingly small, while the l)roportion of weed seed is astonishingly large, in some cases 224 BIRDS L\ THEIR RELATlOXS TU MAX. crops and gizzards being literally gorged with Imndreds of seeds of ragweed."^ The Ruffed Grouse as a game-bird ranks higher in popular esteem in the East than any other bird. The flesh is white and delicious, and its wariness and rapid flight exact the best efforts of even the most experienced sportsman. Its food habits are of secondary importance, but nevertheless interesting, The following, from the pen of Dr. A. K. Fisher, of the Depart- ment of Agriculture, Washington, bears directly on this point. THE la FFEI "The ruffed grouse is very fond of grasshoppers and crickets as an article of diet, and when these insects are abundant it is rare to find a stomach or crop that does not contain their remains. One specimen, shot late in October, had the crop and stomach distended with the larva? of Edema albifrons, a caterpillar which feeds extensively on the leaves of the maple. It is called the red-humped oak-caterpillar. ^ Judd, Yearbook, Dept. Ag., 1898, p. 231.

Beechnuts, chestnuts, and acorns of the chestnut and white oaks are also common articles of food. Among berries early in the season the blackberries, blueberries, raspberries, and elder-berries are eaten with relish, while later in the year wintergreen, partridge-berry, with their foliage, sumach-berries (including those of the poisonous species), cranberries, black alder, dogwood, nanny-berries, and wild grapes form their chief diet. In the fall the foliage of plants often forms a large part of their food, that of clover, strawberry, buttercup, wintergreen, and partridge-berry predominating. In the win- ter these birds feed on the buds of trees, preferring those of the apple-tree, ironwood, black and white birch, and poplar." In isolated cases ruffed grouse cause some damage to fruit- trees by eating the buds in winter. The extent of the injury w^hich a grouse is capable of doing in a season may be esti- mated from the contents of a crop examined by us. It was taken from a female shot in January, and contained three hundred and forty-seven apple-tree buds, eighty-eight maple buds, and twelve leaves of sheep-laurel. This was, of course, a single meal, and, as two such meals are eaten per day, it must be reckoned as half the daily consumption. One of the crops of four birds killed during the latter part of September and subjected to the same scrutiny showed barberries five per cent., sumac seeds twenty per cent., and apple pulp twenty per cent. Another contained ten per cent, of mushrooms and ninety per cent, of red-humped oak-cater- pillars (Edema alblfrons). The other two were sliot from the same flock at the same time. Their crops were packed with the oak caterpillars above mentioned and white-oak acorns, the ratios being sixty per cent, and seventy-seven per cent, of caterpillars against forty per cent, and twenty-three per cent, of acorns respectively. The Prairie-Hen is of more importance than any other member of the grouse family. It is abundant in the prairie region drained by the Mississippi, and furnishes regular occu- THE PIGEONS, GROUSE, AND SHORE-BIRDS. 227 pation for a multitude of gunners. Markets east and west are supplied with great numbers of these birds. The food of this species seems to be not materially different from that of other grouse in temperate latitudes. Insects form the major portion of the diet in summer. It is fond of grasshoppers and lives on them almost exclusively when they are sufficiently abundant. In autinnn and winter it is usually found in the grain-fields feeding on cereals as well as seeds and berries. In the north- ern portion of its range the females usually migrate southward to escape the rigors of winter, leaving the stronger males on the home ground. The Columbian Sharp-tailed Grouse, which ranges over the Great Plains and from northern California to Alaska, ranks among the highest as a game-bird and its flesh is unexcelled for the table. It feeds on berries, among which may be mentioned the snow-berry, bear-berry, whortleberry, and haws of the wild rose, seeds, grains, and insects. The Dusky Grouse and its closely allied races, the Sooty Grouse and Richardson's Grouse, which together extend through the Rocky Mountains and westward to the Pacific, are perhaps the finest of our grouse. The dusky grouse is large, weighing about tliree i)ounds, and during the greater part of the year its flesh has a resinous flavor much relished by those accustomed to it. Except for a little while in summer, when it descends to the ground to feed on berries and seeds, it lives mainly in the pines and firs, the leaves of which constitute its main food. Of all our game-birds none arc so handsome as the several species of plumed i)artridges found west of the Rocky Moun- tains. The Mountain Partridge, found along the Pacific coast from San Francisco to Washington, and the California Par- tridge, with two races representing it in the southwestern part of the United States, have an economic value, both as to food habits and table (pialitics, similar to the eastern bob- 228 BIRDS IN THEIR RELATIONS TO MAN. white. They may readily be kept in confinement and are therefore well adapted for stocking preserves wherever the environment is suitable. THE PLOVERS. The plovers are generally distinguished by their bills, which are of only medium length and are constricted between the base and tip ; most of the birds lack a hind toe. Economi- cally they stand with the rest of the shore-birds. Of the half-dozen species found in our territory, we will consider the three most important, — namely, the ring-neck plover, the killdeer, and the golden plover. The Ring-neck Plover is a diffused species, abundant during the seasons of migration, especially along the beaches. Though numbers of them are shot, the bit they furnish seems hardly worth the ammunition. They are of more value living, as eleven stomachs examined by Professor Aughey testify : in each were from fifty-three to sixty insects, more than half being locusts. In many parts of the United States the Killdeer, or the Killdeer Plover, is one of the most familiar country birds. It is a summer resident in most of the Northern States. It commonly occurs in upland pastures, as well as along the margins of shallow ponds or the beaches of lakes or the ocean. It winters in the South : in Florida we have seen these birds abundant during January, in small flocks spending most of their time along the shores of the numerous ponds and lakes of that State. The major portion of the food con- sists of insects ; angle-worms, crayfish, and similar creatures making up the remainder. In the stomachs of thirteen speci- mens examined by King there were found ants, grasshop- pers and crickets and their eggs, caterpillars, moths, wire- w^orms, curculios, plant-beetles, a crane-fly, and angle-worms. " The food-habits and haunts of the killdeer are such as to bind it closely in economic relation with that all too small THE I'I(;E()\S, (illUUSE, AM) SHOliE-BIHDS. 229 band of birds which hke the meadow-lark frequent the open cultivated fields. On account of this relationship the killdeer plover should be stricken from the list of ' game-birds,' and encouraged to breed in greater abundance in cultivated fields and meadows." Many years ago a writer in the Southern Planter stated that the Southern farmers erroneously thought that the killdeer destroyed young turnips. " I have several times dissected the gizzards of killdeers," he writes, "to show their destroyers that they contain no vegetable substance, and nothing, indeed, but the little bug so famous for destroying young turnips and tobacco plants. These little hopping beetles are a great nuisance in the land, and seem to be rapidly increasing. The killdeers are their natural enemies, and formerly collected in large numbers to fulfil the purposes of their mission.'' ^ The Golden Plover breeds in the Arctic regions, but in the migration season it is very abundant and is highly esteemed as a game-bird. It feeds on grasshoppers and other insects, worms, and berries. THE SNIPES. In the snipe family are many birds highly valued as game- birds, and some tliat are useful as insect destroyers. At the head of the list stands tlie American Woodcock, a familiar game-bird in the Eastern States and occurring as far west as Nebraska. Few birds have so many good points as this : it is pre-eminently a game-bird in every sense of the term, de- manding all the skill of the hunter and being unexcelled in the quality of its flesh. It is one of the earliest arrivals in spring and the return flight is not completed until late in autumn. In spring and early summer it lives in swampy places, probing the black mud with its long bill for worms. In August it flies out to ^ Quoted hy Wilson Flagg, Agr. of Mass., 18G1, pt. II. \). oa. 230 BIRDS IN THEIR RELATIONS TO MAN. the corn-fields, where it finds an abundance of worms, grass- hoppers, and otheir insects, the shade of Uie taU corn being quite as agreeable to these birds as the tangles of the swamp. Later they return to the runs, but after the leaves have begun to fall they may often be found on high ground, in hard-^^'ood forests, or among the high shrubbery of neglected pastures. Here they turn over leaves, looking for hidden insects and larvae that lie underneath. This is in October when the woodcock is at its best. A curious feature of a woodcock's bill, recently discovered, is that it is able to bend its upper mandible upward towards the point, which must aid it in the process of feeling about for worms deep in the soft eartli. "The growing scarcity of woodcock,*' writes Dr. A. K. Fisher, "is a matter of serious alarm, and one deiiianding prompt action. It must be remembered that there is far more diffi- culty in saving it from extinction than in preserving gallina- ceous birds, such as quail and grouse. In the case of these birds, with their extraordinary fecundity, it is not difficult to restore a depleted covert ; for witli the addition of a few im- ported birds, aided by a short term of protection, they should soon reach their former abundance. With the woodcock, however, the situation is different ; for the impracticability of restocking, the nature of the food, the migratory habits, and the small number of young are serious obstacles to successful restoration. Quick and effective measures are needed. In many localities in the North where twenty-five years ago a fair sliot with a good dog could secure forty or fifty birds in a day's hunt, it is doubtful if ten per cent, of the former bag could now be obtained. During the past autumn (1901) the writer visited hundreds of acres of good woodcock ground in northern New York without fiusliing a bird or seeing any considerable signs. Reports as to the scarcity of birds come from numerous points, and even in the most favored localities the decrease within the past twenty years has been fifty to sixty per cent." THE PIGEONS, GROUSE, AND SHORE-BIRDS. 231 This scarcity is to be attributed chiefly to lack of protec- tion by law in the Southern States, where the species passes the winter, and to the spring and sunnner shooting in many of the Northern States. It is greatly to be desired that these evils should be remedied before this valuable bird becomes practically extinct, The American or Wilson's Snipe is similar in its make-up to the woodcock, but it chooses different abodes. This snipe is found in open wet places, in meadow^s, or on sedgy banks, where it can force its long, sensitive bill into the soft turf. Besides the worms taken in this way, it also catches many grasshoppers and other insects found upon the surface. Eight out of eleven stomachs opened by Professor Aughey contained from thirty-eight to sixty locusts each, besides other insects. The toothsomeness of the snipe is equal to that of the woodcock, though its size is somewhat less. The Gray Snipe, or Dowitcher, is similar to the last, except that it is chiefly confined to the coast and consequently destroys few noxious insects, though it is quite as much a favorite with the gunner. The Marbled Godwit is one of the largest of the shore- birds ; it is known on the Atlantic coast only in the South, but is widely diffused in the temperate regions of the interior. During the breeding season it is often found on the prairies some distance from water. Its diet is purely insectivorous. Richardson tells us that on Saskatchewan plains it frequents marshes and bogs, walking on the swamp moss, and thrusting down its long bill to the nostrils in quest of worms and Jeeches. The HuDsoxiAN Godwit is somewhat smaller than the last, and, though more widely distributed, is far less common. The WiLLET occurs as a summer resident throughoul the country, though more commonly coastwise. It is a large, noisy species, not different in its food habits from shore-birds in general. II Collows marshes, often amioying hunters by its 232 BIRDS IN THEIR RELATIONS TO MAN. shrill notes of alarm. Other birds have learned to take warn- ing when the willet cries, and leave a dangerous neighborhood. The name tattler has been applied to it and to others of its class. In spite of all their acuteness, willets often fall victims to the huntsman, large numbers of them being shot every season. The Greater Yellow-legs is another tattler much sought in the marshes. It is chiefly a migrant through the country at large, noisy and restless like the willet. The Upland Sand-piper, commonly called the Upland Plover, is something of an anomaly, being fitted out with a wader's bill and legs, yet avoiding the Avater. It is common from the Rocky Mountains eastward, breeding on the prairies of the Western States and on high grass-land in the East. It feeds on beetles, grasshoppers, and other insects, and is a continual benefit while it stays. Aughey states that in Nebraska in locust years "the bulk of the food of this species consisted of locusts." Rev. J. H. Langille relates that this sand-piper some- times devours cantharides ; its flesh then becomes a violent emetic. It holds a high place as a game-bird and is unsur- passed for the table. THE curlews. The curlews are distinguished from the other snipes by their size and long decurved bills. Of the three species found in our limits, the Long-billed Curlew, or Sickle-bill, is the largest and most abundant. Its habitat is the whole of North America. It breeds throughout its range, but most abundantly along the Atlantic coast and on the prairies of the Northwest. These birds are generally found near the water, feeding upon the various forms of animal life common to the shore. In summer they devour many grasshoppers and kindred insects. Of ten stomachs examined by Aughey, eight had from fifty-one to seventy locusts, besides seeds and other insects ; the other two had from fifty-three to sixty-one other insects and from fifteen to twenty seeds. Wilson tells us that in the fall they THE PIGEONS, GKOLSE, AND SHUKE-BIKDS. 2:]:3 frequent uplands in search of bramble-berries, upon which they get very fat. The HuDsoNiAN and Eskimo Curlews are migrants only, breeding in high latitudes and mostly })assing beyond our southern boundaries in winter. Their food habits are quite similar to those of the sickle-bill. All eat more or less seeds and berries, differing in this respect from the majority of sand-pipers. All are excellent for food. There is quite a list of small sand-pipers which are very sim- ilar to each other in economic value. Their diet consists chiefly of aquatic insects, worms, and small mollusks. Their open habits do not commend them to sportsmen and they are too small to be of much consequence as food. The pot-hunter, however, destroys numbers of them each season along the beaches, preferring thus to earn a few pennies by a slaughter of the innocents and to gratify a lust for murder rather than to turn his hand to honorable labor THE PHALAROPES. The phalaropes are a family of small sand-piper-like birds, having lobed toes and thick under feathers Avhich enable them to swim. They are usually seen floating lightly about upon the water, catching flies in the air or gathering larvne from the water ; on shore tliey take worms and various aquatic forms found there. The best-known representative of the family is Wilson's Phalarope, which is abundant in the Mississippi Valley and westward, though rarely occurring east of Illinois. Two other species, the Red and Northern Phalaropes, appear in limited numbers during migration, but they are of comparatively little importance. THE rails. The rails are narrow-bodied birds of medium size which live in reedy marshes. They are much sought by sportsmen and are considered very good birds for the tabic. They are very 234 BIRDS IN THEIR RELATIONS TO MAN. shy and hard to flush, dependmg for safety more upon their legs than upon their wings. They fly awkwardly and with seeming difficulty, a puzzling matter when the extent of their migration is considered. The members of the genus Rallus, comprising the Clapper, King, and Virginia Rails, have bills longer than the head, and feed chiefly upon grasshoppers, snails, slugs, small crabs, aquatic insects, and occasionally a few seeds. The clapper rail frequents salt-marshes as far north as Massachusetts. HEAD OF CLAPPER RAIL. The rails are found from Texas to Kansas and eastward, though in the East not usually north of the Middle States. Seven stomachs of king rails taken at difl'erent times between May and October and opened by Aughey each contained from seventeen to forty-eight locusts and from fourteen to forty-nine other insects, besides a few seeds. The Virginia rail is the most common rail in the Eastern States as far north as New England. Members of the genus Porzana, including the Carolina Rail, the Black Rail, and the Yellow Crake, have rather THE PKJEONS, (IKOUSE, AND SHOKE-BIKDS. li.v) (hick J)ills, sliorlf^'r Hum the head, and feed more uii ve;,Tla])le iiiaHci". The only one of Hie ^»Toiij) common (Mion^h h> be of any special iinportaiice is Hie Carolina rail. Thousands of the latter are killed annually in the Atlantic States for market. They feed largely on seeds in tlie fall, when they become fid and are excellent eating. They are a diffused species, breeding from the Middle States northward. THE GALLINULES, COOT, AND CRANES. The gallinules resemble the rails in their habits and appear- ance ; they are larger than most rails, however, and are dis- tinguished by a horny plate, or shield, which extends from the bill upward over the forehead. Their food is not noticeably different from that of the genus Porzana of the rails. The Purple Gallinule is a resident of the South Atlantic and Gulf States. The pLORmA Gallinule is found throughout the warmer portions of the country, frequently reaching New England. Both are called mud-hens by gunners. The term mud-hen is also applied to the Coot, which is allied to the gallinules, having the same outline and frontal shield. It is peculiar in having lobate toes, which enable it to swim easily. Most of its time is spent on the water along marshy shores, where it finds shelter among the tall grass and reeds. Its food consists of insects, aquatic plants, and small mollusks. Its flesh is frequently eaten, though generally it is not highly esteemed. Tlie cranes are large \vaders resembling the herons in out- ward appearance, but differing from them in structure and habits. The Whooping Crane is chiefly a migrant, moving up and down the Mississii)pi Valley with the changing seasons; it is an omnivorous feeder. Audubon fouml these birds in November tearing up lily-roots from the bottom of a dry pond. Again in the same month he says, ^' They resort to fields, and feed on grain and peasaiid dig up ])()tat(^es, which they devour with remarkable gnM'diness.'' In April they had left the fields 2:]C) BIRDS IX THEIR RELATIONS TO MAN. and removed to the swamps and lakes, where they caught frogs, lizards, snakes, and young alligators. He saw one catch and swallow a butterfly, and from the stomach of another he took a fifteen-inch garter-snake. Wilson credits them with eating mice, moles, and rats. The Sand-hill Crane is common in the South and West, being a more southerly species than the whooping crane. Four stomachs of this crane examined by Aughey showed from thirty-seven to eighty locusts and from thirty-six to seventy-eight other insects in each, besides more or less seeds. Both species are edible, but they should not be sacrificed for this purpose. THE HERONS, IBISES^ AND STORKS. The herons are waders, with sharp, spear-like bills, that fre- quent shores and marshes, feeding on any sort of animals small enough to be swallowed that may come in their way. Their flesh has a fishy taste which renders it unpalatable to most people. Taxonomists separate the ibises and storks from the herons proper, but, as they all have the same economic value, it will best serve our purpose to consider them under the same heading. The White Ibis is an abundant resident of Florida, common throughout the South Atlantic and Gulf States and northward to Ohio. It feeds upon crabs, crawfish, snails, and the like. Audubon relates tliat when the crawfish burrows deeply to find water in dry seasons, this ibis crushes the mound raised about the burrow; some of the dirt falls down upon the crawfish, which hastens to the surface to throw it out again, when the crafty bird quickly plucks him from his hiding- place. The Wood Stork, better known as the Wood Ibis, is a large, gregarious wader, usually found in the thickly-wooded swamps of the Southern States. It devours fish, snakes, frogs, young alligators, crabs, rats, and young birds. It is related to the famous white stork of Europe. THE PIGEONS, (iROUSE, AND SHOKE-BIKDj 'S'U The Bittern, or Stake-driver, is coiiimon throughout the country. It is a solitary bird, inhabiting weedy marshes, but known by its pecuHar cry. During the day it hides among the tall grass and reeds, picking up a grasshopper or a beetle, or perchance a young mouse now and then. Towards even- ing it seeks the water and partakes of its regular meal, which consists principally of small frogs and fish. The Great Blue Heron, the largest of its tribe in America, is well known in all quarters. Its tall and awkward form is often seen on the borders of ponds and streams, when it moves with a stealthy tread, on a combined watch for food and enemies. It lives principally upon fish and frogs, but readily devours grasshoppers, dragon-flies, water-boatmen, seeds, and even meadow-mice. Small pickerel, which like to bask in the sunshine in shallow water, are destroyed in great numbers by this heron. The Green Heron is another widely diffused species. It is the common small heron found beside brooks and in muddy places at or near water margins. Being small, its diet is re- stricted to worms, insects and their larvae, tadpoles, small fish, and frogs. The Great White Egret is found in the Southern States, but in much smaller numbers tlian formerly. This egret, in com- mon with several smaller species, has for years been the object of unremitting persecution by plume-hunters. As the coveted plumes appear only at the nuptial season, they are easily pro- cured by visiting the heronries when the egrets assemble in great numbers to breed. One man has been known to kill several hundred old birds in a day, leaving }he young to starve and the dead bodies to rot after a few choice feathers have been plucked. Egret-plumes are worn by certain dressy organ- ized bodies of men, military and otherwise, and by ladies. Much has been said and written of late against wearing feathers of wild birds, and it is to be hoped that the tide of popular sentiment may be turned against the i)ractice before such 238 BIRDS IN THEIR RELATIONS TO MAN. unfortunately beautiful birds as the egrets shall have been exterminated. Although there are a number of herons that have not been mentioned, a complete enumeration would add nothing to what has already been said concerning the relations of herons to the welfare of man. While the direct economic value of these graceful and beautiful birds may not be very great, they add a charm to tlie scenery of lakes and ponds, the value of which is not likely to be over-estimated even by those keenly alive to the beauties of nature. It is a pity so many thought- less people consider such birds legitimate prey for gun and rifle. They deserve the fullest protection of the law and the good-will of all intelligent people. CHAPTER XX. THE WATER-BIRDS. THE DUCKS, GEESE, AND SWANS. The members of this liToup are omnivorous birds, eating animals and vegetables in varying ratios, as may be readily guessed by any one familiar with domestic varieties. Their economic status, however, does not depend so much upon what they eat as upon the quality of their flesh. Their feathers have a value, to be sure, bat that is a secondary consideration, which is pretty nearly constant throughout, while the great variation in ducks and geese from a gastro- nomic standpoint is worthy of particular attention. The Mallard Duck is an abundant species, except in New England, where it is rather rare, being replaced by tlie black or dusky variety. The common greenheaded domestic duck is of mallard stock, though probably introduced from Europe, where the mallard is a common wild species. During autumn the mallards come into the United States in great numbers — the majority breeding beyond our northern limits — and are much sought by sportsmen. They weigh from two to three pounds each. The Black Duck, or Dusky Duck, is a favorite in the Eastern States, where it is abundant, breeding in New England and northward. It is nearly related to the mallard, which it equals in size and quality. The Teals, blne-wiiigcd and green- winged, are two small ducks well known through the country, exce})t in New England, where they are not so connnon as elsewhere. Being httle, they are of less imi)ortance than the preceding, though they are quite as good for eating. Other ducks of equal rank with those already mentioned are the gadwall, widgeon, shoveller, pintail, and wood-duck. All art 21)9 240 BIRDS IN THEIR RELATIONS TO MAN. inland birds, feeding upon insects, mollusks, nuts, grass, and grain. In the West tliey visit the vast grain-fields in harvest- time and soon get in excellent condition for the table. ''The WooD-DucK, or Summer Duck," writes Dr. A. K. Fisher, '4s the most beautiful of all the members of the large and diver- HEAD OF DUSKY DUCK. sified duck family, and, on account of its beauty and lack of shyness, is one of the best-known species in the country. It is not seclusive, often making its abode near towns, or perhaps in the vicinity of farm-houses, Avhere it may be found feeding or associating with barn-yard ducks. It takes kindly to domestication, and is easily tamed and induced to breed in captivity. Its favorite haunts are small lakes, weedy ponds, or shady streams in the midst of, or in close proximity to, scatlered woodlands, and, except during migration, it is rarely met with about open bays or lai^e bodies of water." THE WATER-BIRDS. 241 This beautiful bird seems in danger of extermination, an event to be deplored by every lover of Nature. Special effort should be made to protect it in its nesting sites and to prevent its being shot during the spring season. Our most popular duck is undoubtedly the Canvas-back, famed among epicures for its delicate flavor, resembling that of celery. This is due to feeding on a water-plant known as wild celery ( Vallisnena), and is not acquired till the birds get to the Chesapeake region, where the plants grow abundantly. Canvas-backs from Chesapeake Bay bring a much higher price HEAD OF OLD SQUAW DICK. than those from other localities. Except for its peculiar appe- tite in the one instance of wild celery, the canvas-back's menu shows no appreciable difference from that of the group just treated of. An associate and relative of the canvas-back is the Red-head, another excellent table bird. In both size and color there is such a strong resemblance between the two that dislionest market-men have been known to impose on customers, not well informed in ornithological matters, by selling red-heads for canvas-back. The Ring-neck and the Greater and Lesser 242 BIRDS IN THEIR RELATIONS TO MAN. SrAUPs belong to the same genus as llie canvas-backs and red-lieads, but they feed more on moHusks and other forms of anmial hfe and are less palatable. The Whistler, or Golden-eye, Old Squaw, Butter-ball, or Dipper, and Ruddy Duck are all easy divers, which feed chiefly on mollusks and similar creatures that they obtain from the bottoms of ponds and lakes. They are often eaten, but pos- sess a fishy flavor that is not relished by most people. Of the more distinctively sea-ducks, only the surf-ducks and eiders need be mentioned. Surf-ducks or Scoters of various species are abundant along the coast from autumn till spring. >r SIKF SCdTKK DITK. Many of them are killed every year, but they are of inferior quality, having a rank taste that comes from a diet of shell-fish. The American Eider and King Eider are both arctic species that rarely come further south than New England. They, in common with other varieties of eiders, furnish eider-down. This down is in great demand in northern European countries for filling coverlets. The best, know^n as live down, is that plucked by the duck from her breast to line her nest, and afterwards abstracted by the down-gatherer. Greenland, Ice- land, and Norway are the chief sources of eider-down. The following quotation from Newton's ''Dictionary of Birds'Mells THE WATER-BIRDS. 243 how the down is obtained in Iceland and Norway, and inci- dentally carries an impressive lesson concernin^^ what may be accomplished by the kindly treatment of wild birds. "This bird generally frequents low rocky islets near the coast, and in Iceland and Norway has long been afforded every encour- agement and protection, a fme being inflicted for killing it during the breeding season, or even for firing a gun near its haunts, while artificial nesting-places are in many localities contrived for its further accommodation. From the care thus taken of it in those countries it has become exceedingly tame at its chief resorts, which are strictly regarded as property, and the taking of eggs or down from them except by author- ized persons is severely punished by law. . . . The nest is generally in some convenient corner among large ston<'s, hol- lowed in the soil, and furnished with a few bits of dry grass, sea-weed, or heather. By the time that the full number of eggs (which rarely if ever exceeds five) is laid, the down is added. Generally the eggs and down are taken at intervals of a few days by the owners of the eider-fold, and the birds are thus kept depositing both during the whole season ; but some experience is needed to insure the greatest profit from each commodity. Every duck is ultimately allowed to hatch an egg or two to keep up the stock, and the down of the last nest is gathered after the birds have left the nest." The FisH-DUCKs, or Mergansers, are characterized by den- ticulate mandibles, which have given them the name of saw-bills. They are expert divers, living chiefly upon fish. We have three species, two of which are commonly called sheldrakes. The largest, to which the books give the name of goosander, spends the winter as ilir north as possible, usually in the larger rivers which have a current swift enough to defy ft-ost. They closely follow the ice as it retreats north- ward in spring, and April finds them at their summer homes. The red-breasted merganser is the sheldrake that reaches the New England coast about the first of May. It is more com- 244 BIRDS IN THEIR RELATIONS TO MAN. mon than the goosander, particularly near the sea. Both of these mergansers are good-sized birds, weighing from three to four pounds, but they are ill-flavored and not generally rel- ished as food. The hooded merganser is a handsome little duck, bearing a high, fan-like crest the whole length of its head. It shows a fondness for small streams and ponds, and eats more or less insects, though small fish, tadpoles, etc., make up the major part of its food. The American White-fronted Goose, best known towards the Pacific coast, differs little from the European white- fronted species, of which the ordinary tame goose is a descendant. Its habits and qualities are similar to those of the domestic bird. Two other species of equal worth are the Snow-Goose, common in the interior, and the Canada or Wild Goose. Canada geese have been crossed with the domestic breed with good results, the hybrid being considered more hardy than the common stock. The Brant-Goose is a mari- time variety, more abundant on the Atlantic coast than elsewhere, though it is sometimes found inland. It feeds on shell-fish and other marine products, both animal and vege- table. Its flesh is not much esteemed. The swans do not differ materially from geese, either in food or flesh. They are wary creatures, rare in the East and nowhere abundant, breeding in high latitudes and appearing in the United States only during the winter. The Trumpeter Swan is found from the Mississippi Valley westward, Avhile the other species, the Whistling Swan, reaches the Atlantic coast as far north as New Jersey. Of the two kinds of swans seen in captivity, the white one comes from England, where it has lived in royal favor for centuries, and the black variety is brought from Australia, where it still exists in a wild state. the gannets. The gannets are large marine birds, goose-like in size and contour, which as they fly seek their fuiny victims and take them THE WATER-BIRDS. 245 by a headlong plunge into the water quite out of sight. They feed entirely on fish, — herring and mackerel being preferred. White Gannet are found on both sides of the Atlantic. On the American side they breed on Gannet Rock, in the Gulf of St. Lawrence, and at one or two other places in that region. Like other gregarious sea-fowl, they suffer much at the hands of the fishermen and are rapidly decreasing in numbers. After the breeding season they follow the open sea in quest of their favorite quarry, and often guide the fishermen to an abundance of herring and mackerel. Their manner of fishing is as methodical as the evolutions of a mili- tary company. They fly in single file, and as each individual comes over a shoal of fish he closes his wings and dashes down with unerring aim into the waves, to appear again in a moment and take his place in line. Along the south Atlantic and Gulf coast is found the Brown Gannet, better known among sailors as the "booby," so named because it has in many instances been so foolish as to alight on ships at sea and allow itself to be caught by the hand. The booby's habits do not materially differ from those of the white gannet. A South American species known only along the coast of Peru contributes to the guano supply. THE DARTER. The Darter, or Snake-Bird, is a native of the Southern States, ranging in summer as far north as the Carolinas and Illinois. Its appearance is that of a duck with rather long fan-shaped tail, extremely long slender neck, small head, and long pointed bill. It is an expert diver, having a curious faculty of being able to swim at any degree of submergence, from high floating to such a depth that only the head remains in sight, when its apparent snakiness is startling. It feeds on a great variety of fish, frogs, lizards, crawfish, leeches, shrimps, young alligators, snakes, terrapin, which it can overtake under water like a true diver. It is a shy, watchful bird, living in secluded swamps. 246 BIRDS IN THEIR RELATIONS TO MAN. THE CORMORANTS AND PELICANS. The Cormorants are large birds, principally maritime yet often straying into the interior, vvhich are represented by dif- ferent species in every temperate quarter of the globe. They are proverbial fishers. In China they are domesticated and trained to fish for their masters, being prevented from swal- lowing their game by a close-fitting ring put about their necks. The common cormorant is found along the Atlantic coast down to the Middle States in winter. The double-crested cormorant is the only one diffused throughout the country. The Mexican cormorant is a tropical species that occasionally makes its way up the Mississippi Valley. They all agree in living exclusively upon fish, and, as they are not sufficiently abundant to interfere with human interests in that line, may be regarded as of no economic account in this country. The pelicans are large, cumbersome birds, remarkable for a capacious pouch of extensible skin between their lower jaws. They are common in temperate regions, feeding mostly on fish and other animals, yet not averse to insects. The White Pelican is common in the Southern States, rang- ing w^ell u}) the Mississippi Valley. It feeds by scooping up its prey as it swims on the water, letting the water run out at the sides of its mouth, and swallowing the luckless creatures left witliin. It walks readily and is able to pick up more or less food on shore. Five Nebraska birds that came into the hands of Aughey had fed as follows : One had eaten a frog ; all had eaten fish, crawfish, and insects. None had taken less than twenty-one insects. Forty-one locusts were found in one stomach and forty-seven in another. A stomach opened by Audubon was found to contain about a hundred small worms. The Brown Pelican, a more southerly bird, confined to the coast, feeds wholly on fish taken at a flying plunge, after the manner of a gannet. THE WATER-BIRDS. 247 THE FRIGATE BIRD AND THE (iULLS. The Frigate Bird, or Man-of-war Bird, is a liuiritime species, having its four toes webbed together ; it resembles in this jjar- ticular the ganncts, darters, cormorants, and peUcans; indeed, it has a double relationship to the })clicans, by reason of its gular sac or pouch. Having a comparatively small body, with extremely long pointed wings and a long forked tail, its powers of flight are astonishing. Frigates lisli for themselves when necessity demands it, but they much |)refer robbing gulls and terns of their well-earned sustenance by forcing them to dis- gorge. They are found on the south Atlantic and Gulf coasts. The gulls are long-winged, web-footed birds, well equipped for both aerial and aquatic navigation. Most of them are winter visitors along the coast, though many frequent the great lakes and other inland Avaters. Fishermen watch tlieir move- ments and are often led to good luck by them. The Manx government protects them because of their usetulness as an index of mackerel schools. Gulls have moderately long bills, somewhat hooked at the tip, suitable for taking animal food. Their diet, however, varies considerably in different species, and, even in the same species, more or less according to the situation and relative abundance of eatables. The Great Black-backed Gull, one of the largest of its kind, belongs to the class which chooses to live on meat and fish. Audubon states that it devours all sorts of food except vege- tables, even the most putrid carrion, but i)refers fresh fish, young birds, small quadrupeds, or eggs. A specimen ex- amined by Professor Aughey had eaten a few grasshoppers and other insects, but mostly fish and frogs. The HERRixii Gull, a much commoner s|)ecies, tlial is found both coastwise and iiitci'iorly, has similar good habits. A sloiiiach cxamiiKMl by Dr. Cones contained the remains of a marsh-hare. Two wliich were examined i)\ rr-olrssoi- Angliey had grasshoppers, hsli, and nioHusks. One shot liv ns had eaten (HiIv reliise of 248 BIRDS IN THEIR RELATIONS TO MAN. an oily consistency. This gull breeds from New England and the great lakes northward. Their eggs, like those of the guille- mot, are taken in great quantities, and young birds are salted and laid in store by dwellers in the far North, although in a land where food is plentiful gull flesh is not relished. The KiTTiwAKE Gull, so far as food habits go, may be classed with those already mentioned. It is a winter visitor, known as far south as the Middle States, chiefly along the coast. Other species range more or less over marshes and high grounds and take a larger proportion of insects. One of these is the Ring- billed Gull, a common species the land over. Those found in the interior consume many insects. One stomach opened by Professor Aughey contained forty locusts ; four others had from ten to thirty-three insects each. All had partaken of fish, crawfish, or mollusks. Bonaparte's Rosy Gull is another common gull interiorly and coastwise, being especially abundant along the Atlantic coast during migration. It is often seen coursing over stubble and ploughed land. Two stomachs opened by N'uttall w^ere gorged with ants, ants' cocoons, and moth pupa^. Franklin's Rosy Gull moves quite across the United States in its migra- tions, its main route lying west of the Mississippi River. Of ten stomachs examined by Aughey, six had from thirteen to fifty-three locusts each, besides a few other insects and remains of fish and frogs ; the rest had from twelve to thirty-nine other insects, together with mollusks, snails, fish, crawfish, and lizards. THE terns and JAEGERS. The Terns resemble the gulls in form and habits, though they are readily distinguished by their smaller size, their buoyant airy flight, and sharply pointed bills. Among those that are most often found away from salt water, and con- sequently the only ones whose food relations especially interest us in this connection, are the least tern, Forster's tern, the gull-billed or marsh tern, and the black tern. The THE WATER-BIRDS. 249 least tern is hardly longer than a swallow. It feeds with equal readiness on insects and aquatic animals ; beetles, crickets, grasshoppers, and spiders are all set down as forming part of its diet. Four stomachs out of eight examined by Pro- fessor Aughey contained from twenty-three to forty-nine locusts each. The others had from four to forty-nine other insects and remnants of fish, lizards, and crawfish. The three other species have like records. Several gull-billed terns killed by Wilson had eaten nothing but large aquatic spiders. Professor Aughey's examination of six black terns revealed from forty- seven to eighty-four locusts each in four, and from twenty- eight to fifty-nine insects in the other two. There was the usual complement of water animals in each. Among the more maritime terns are the royal, sandwich, Caspian, roseate, and sooty terns, and the noddies. These feed almost wholly on small fish and mollusks. The more delicately tinted terns have been subjected to an outrageous slaughter for their skins for millinery use, to gratify a lingering taint of savagery in w^oman, a desire to adorn her- self with feathers, — a la primitif. Wholesome legislation and a more enlightened public opinion, however, are slowly com- ing to the rescue of the disappearing birds. The Black Skimmer is a peculiar tern-like bird, wiiich has its lower mandible about an inch longer than tlie upper. Its food consists of shell-fish, shrimps, small crabs, sand-fleas, etc., which are plowed from the water by the knife-like lower mandible as the bird skims along with lowered head just above the surface. The Jaegers form a small family. They resemble gulls in their appearance, and are chiefly maritime, though sometimes drifting inland ; they are parasites of the smaller terns and gulls. Their favorite method of gaining a livelihood is to pursue a gull or tern and so tire and pester it till it disgorges its last meal, which is quickly devoured by tlie robber. An inland straggler was found to have eaten fish, frogs, crawfish, 250 BIRDS IN THEIR RELATIONS TO MAN. and even a few grasshoppers. They catch their food when they cannot steal it. The four that visit us are the skua gull, the pomarine, parasitic, and long-tailed jaegers. None of them are common. THE PETRELS AND AUKS. The Petrels, including fulmars and shearwaters, are pelagic birds, adapted for both flying and swimming, that rarely land except to lay their eggs. They will follow a ship for days together, picking up such bits of food as may be thrown over- board. The stomachs of several specimens of Wilson's petrel, opened by the naturalist for whom they were named, showed barnacles, seeds of gulf- weed, and greasy refuse from vessels. Leach's petrel, a common species off the New England coast and northward, attends fishing-vessels for the sake of the waste from the cleaning tables. Fulmars accompany whalers and feast upon scraps of blubber. All petrels are especially fond of fatty matter. The Auks are an exclusively marine family of diving birds that feed wholly on animal substances, such as small fish, shrimps, roe, and crustaceans. The puffins, which constitute one branch of this family, exhibit strange nuptial changes in their bills. As the breeding season advances, the bill increases in a vertical direction until it is nearly as deep as the head itself. This increase is caused by the growth of additional flakes, which are shed with the feathers during the moulting season. The Common Puffin, or Sea Parrot, is the only one to visit our eastern coast. Other auks have seasonal changes of bill, but none of them belong on the Atlantic coast. The Great Auk, which has been extinct for more than fifty years, was formerly killed in great numbers for its flesh and feathers. Its wings were so small that flight was out of the question, and, though able to lake pretty good care of itself in the water, when on land it was at the mercy of any foe larger and more THK WATEli-BIHDS. 251 powerful than itself. Tlie early fishermen sought great auks on the barren northern islands in nesting time, slaughtered them right and left with clubs, and salted their flesh. This ruthless destruction could have but one result. Only a few skins, eggs, and bones in museums remain as tangible evi- dences of tliis once abundant bird. Another branch of the auk family, including several species which have been and still are to some extent severely perse- cuted, comprises the Guillemots, or egg-birds. In this case it is not the birds themselves so much as their eggs that attract marauders. Each spring the guillemots congregate by thousands on certain rocky islands and shores to deposit their eggs. In such vast numbers do they come that they fairly cover the ground while incubating. The eggs are quite pala- table while fresh, but most of them are sold for use in the arts, the albumen they contain being a requisite in several industries, such as the manufacture of patent leather and in clarifying wine. Gathering the eggs of this and other sea- birds was formerly a fixed occupation for a class of rough characters known as eggers, who regularly plied their trade while the season lasted. In order to insure fresh eggs, they would first break every egg on the ground, then come daily afterwards for their harvest. An easy way to smash the eggs, and one often followed, was to roll barrels back and forth over the whole nesting-place. Egging was carried on so per- sistently that tlie number of birds became seriously decreased, and our Eastern States as well as the Canadian government have prohibited it. The following extract from Audubon's "Eggers of Labrador" presents a vivid picture of the people and their business as he saw them there. "The vessel herself is a shabby thing: her sails are patched ; her sides are neither painted nor even pitched ; no, they are daubed over, plastered and patched with strips of seal-skin along the seams. Her deck has never been washed or sanded ; her hold — no cabin has she — though 252 BIRDS IN THEIR RELATIONS TO MAN. at present empty sends forth an odor pestilential as a charnel- house. The crew, eight in number, lie sleeping at the foot of their tottering mast, regardless of the repairs needed in every part of her rigging. . . . As I suspect her crew to be bent on the commission of some evil deed, let us follow her to the first harbor. The afternoon is half over. Her crew have thrown their boat overboard ; they enter and seat them- selves, each with a rusty gun. One of them sculls the skiff towards an island for a century past the breeding-place of myriads of guillemots, which are now to be laid under contri- bution. At the approach of the vile thieves, clouds of birds rise from the rock and fill the air around, wheeling and screaming over their enemies. Yet thousands remain in an erect posture, each covering its single egg^ the hope of both parents. The reports of several muskets loaded with heavy shot are now heard, while several dead and wounded birds fall heavily on the rock or into the water. Instantly all the sitting birds rise and fly off affrighted to their companions above, and hover in dismay over their assassins. . . . See how they crush the chick within its shell, how they trample over every egg in their way with their huge and clumsy boots. Onward they go, and when they leave the isle not an egg that they can find is left entire. The dead birds they collect and carry to their boat. Now they have regained their filthy shallop ; they strip the birds by a single jerk of their feathery apparel, while the flesh is yet warm, and throw them on some coals, wiiere in a short time they are broiled. The rum is produced when the guillemots are fit for eating, and after enjoying themselves with this oily fare, and enjoying the pleasure of this beastly intoxication, over they tumble on the deck of their crazed craft, where they pass the short hours of night in turbid slumbers. ... On Guillemot Isle the birds have again settled and now renew their loves. Startled by the light of day, one of the eggers springs to his feet and arouses his companions. . . . The master, soon recollecting THE WATER-BIRDS. 253 that SO many eggs are worth a dollar or a crown, casts his eye towards the rock, marks the day in his memory, and gives orders to depart. The light breeze enables them to reach another harbor a few miles distant, in which, like the last, lies concealed from the ocean some other rocky isle. Arriving there they reenact the scene of yesterday, crushing every egg they can find. For a week, each night is passed in drunken- ness and brawls, until, having reached the last breeding-place on the coast, they return, touch at every isle in succession, shoot as many birds as they may need, collect the fresh eggs, and lay in a cargo.'' THE LOONS AND GREBES. The Loons are large, powerful divers, that are equally at home in fresh and salt water. Owing to their wariness, and also to the fact that they cannot fly without a long course in which to get a good start before leaving the water, they are not usually found in the smaller streams and ponds. Except during the period of incubation they rarely venture ashore. They feed almost wholly upon fish, which they dive for and pursue with great energy. In the economical balance they have little Aveight either way. The fish they consume are generally worthless, while their own flesh is hardly better. The common loon is a picturesque element in the scenery of our northern lakes in summer. In winter it may be found in the sea or wherever there is plenty of open w^ater. The red-throated loon is a more northerly bird that breeds entirely beyond our limits, but is found fairly common out of breeding season. The black-throated loon is an arctic species rarely appearing in the United States. The Cjkebes constitute a branch of the diver family. Their chief peculiarities are wide, flat, unwebbed toes and an entire lack of tail. They are essentially fresh-water birds, designed, like divers in general, to glean a livelihood in the liquid ele- ment. Small fish, lizards, tadpoles, and aquatic insects, with 254 BIRDS IN THEIR RELATIONS TO MAN. now and then a blade of grass or a few seeds, constitute their usual diet. Inasmuch as they are unable to travel on land with any ease, owing to the rearward position of their legs, only such insects as belong to the water or accidentally fall into it are eaten. Of the four varieties common to the eastern half of the United States, the little Dabchick, or Pied-billed Grebe, is perhaps the best known. Its bill is shorter and thicker than the bills of other kinds, and it may readily be guessed that its food is not so strictly of an animal nature. A single stomach examined by us contained the broken wing- covers of many beetles, a few feathers, evidently from its own breast, and considerable sand. The other three species have spear-like bills and have practically identical food habits. They are the Red-necked Grebe, the Horned Grebe, and the Eared Grebe. The first two are found at large throughout the country. The (\ared grebe belongs west of the Mississippi River. Of two stomachs of the last named opened by Pro- fessor Aughey, of Nebraska, one contained nine locusts, some grass, a few seeds, and the remains of crawfish ; while the otlier had five grasshoppers, a few other insects, fish, and crawfish. None of the grebes are much esteemed as food, being rather coarse and rank-flavored. Both loons and grebes are levied u|)un to satisfy the demands of fashion, the breast portions of their skins being prized by milUners. CHAPTER XXI. THE CONSERVATION OF BIRDS. I. NON-GAMEBIRDS THEIR DESTRUCTION, PROTECTION, AND ENCOURAGEMENT. According to the latest classification, there are eleven hun- dred and twenty-four species of birds inhabiting America north of Mexico. They are included in seventeen orders. For our present purpose we will divide them into two classes, — namely, gamebirds and non-gamebirds. The gamebirds, comprising only five orders, amounting to two hundred and twenty-two species, will be considered in the next chapter. The nine hundred and two species and subspecies in the twelve orders of non-gamebirds are of all sizes and of a wide variety of habits. While of little or no use as food, and generally recognized as important aids in keeping insects within supportable limits, — or, in case of birds that prefer other food than insects, either beneficial or at least harmless, — they have too often been slaughtered and otherwise per- secuted. It seems a well-established fact that birds, as a class, are now less numerous in the United States than they were a century or more ago. While some species have doubtless become more abundant under the changed conditions of modern civilization, others are very much rarer, and a few appear to be approaching extinction. It was, of course, inevitable that the changes produced by man's interference with natural conditions should have a tremendous influence upon the nalive fauna. Some birds have found the new dis- pensation better suited to their wants than the old ; others have changed their liabits and made the best of it ; while others have been so relentlessly persecuted that their only 255 256 BIRDS IN THEIR RELATIONS TO MAN. hope of survival lay in retreating to inaccessible localities. The wholesale destruction of primeval nesting-sites has been a potent factor in the change produced, but, fortunately, many of the most useful birds found substitutes that answered the purpose very well : kingbirds, chipping-sparrows, cedar-birds, and robins have apparently been glad to adopt the imported apple tree for a home tree ; swallows, swifts, and phoebes have left the cliffs and hollow trees they formerly possessed for rafters and chimneys and artificial houses put up for their benefit. Meadow-larks, vesper, savanna, and other "ground" sparrows inhabiting grass-lands have undoubtedly increased in numbers and widened their habitat since mowing fields have so largely superseded timbered areas. Even under normal conditions birds have to encounter grave perils that many of them, particularly of the smaller varieties, are unable to withstand. Of these their annual migration over hundreds and thousands of miles of land and sea probably is most fatal. Their periods of travel are sea- sons of strenuous weather. Gales carry them out to sea and leave them exhausted to perish on the waves. Unwonted cold in the South sometimes destroys them in great numbers. A backward spring in the North, by retarding insect develop- ment, adds hunger to cold. At the end of the long journey, tired and lean, the birds suffer greatly w^hen spring is late. Warblers, orioles, tanagers, and other sylvan species may be seen searching among the stubble for something to eat. Their feebleness is apparent. Sometimes a cold storm follows, and when such is the case many invariably die. It is interesting to note that during such a stress of weather many birds that ordinarily frequent the woods come to the vicinity of houses. A parula warbler has been known to seek refuge in a store doorway, a humming-bird to crawl into a crevice in a garden gate, and redstarts and a Canadian warbler to find shelter in a barnyard. Birds found dead after such a storm are greatly emaciated, showing plainly the effects of starvation. Well fed, THE CONSERVATION OF BIRDS. o / they could stand Uic wcallicr, IjiiI liuii^'-cr and cold combined they could nut endure. Young birds are subject to many dangers before reaching maturity. Foxes, cats, skunks, minks, weasels, squirrels, hawks, owls, crows, jays, and snakes are always seeking to devour them. The percentage of young birds preyed upon by predaceous animals is certainly quite large. Heavy rains destroy many more. Adult birds also fall victims to preda- ceous animals, particularly hawks and owls, though less often than the young. Light-houses, situated as they are in a main thoroughfare of migration, cause the death of many birds. Most birds fly by night, and, coming into a beam of light, they follow it to their destruction. Telegraph and telephone wires are another dan- ger. Fortunately, many birds that hit them are not killed, so they are able to profit by experience. A western writer has noted that in a certain locality the number killed during the first few years after the wires were put up was much larger than the number killed in later years. But besides these natural causes and the inevitable results of the white man's occupation of the American continent, certain causes have been, and still are, at work which tend greatly to decrease the number of birds possible under exist- ing conditions. To a large extent these agencies are the result of human greed, cruelty, and ignorance, and the havoc they commit may be avoided by proper laws based upon and sup- ported by tlie opinion of an enlightened public. Perhaps one of the most constant and serious of these agencies is the egg-collecting or nest-destroying small boy. In almost every town or village there may be found a dozen or more youths who have frequent attacks of the collecting fever. Unfortunately, the fever is often of the intermittent type, and the season's collections are allowed to go to ruin before the advent of another spring. Every nook and cranny for miles around the head-quarters of such a coterie is examined 17 258 BIRDS IN THEIR RELATIONS TO MAN. by sharp eyes, and the great majority of birds' eggs are gath- ered in. Probably Avith ninety-nine boys out of a hundred these egg collections are soon forgotten, while the hundredth boy is too likely to become a mere collector who strives to see how many varieties of eggs he can get together without refer- ence to their natural history values. To this class of collec- tors we owe the existence of the egg-dealers w^ho collect eggs in large numbers to sell. The latter are the mercenary collec- tors, while the intermittent types are the aimless ones, — a classification suggested by Col. W. H. M. Duthie, a Scottish ornithologist, Avho well defines the "true collector" as "a nat- uralist acquainting himself with birds, their habits, flight, migration, and breeding haunts ; his egg-collecting being only one of the means of acquiring knowledge.'" Birds' eggs are sometimes collected by children to serve as Easter gifts the following season, — a sacrilege to which atten- tion need scarcely be called to reveal its inappropriateness. Such an Easter present is a sacrifice of innocence rather than a thank-offering. Unfortunately, the boy of the period does not limit his destructive powers to the gathering of eggs. The recent increase in cheap fire-arms has placed within his reach the means of killing feathered " game" at all seasons of the year. To this fact is due much of the diminution in the number of small birds in the vicinity of towns and cities. Dr. R. W. Shufeldt thinks that the wholesale destruction carried on by the army of unscrupulous small boys " is a reason for bird decrease before which other reasons stand aghast." He reports meeting near Washington, D. C, " one such youngster, and upon examining his game-bag, found it absolutely full of dead bodies of birds which he had killed since starting out in the morning. One item alone consisted of seventy-two ruby and golden-crowned kinglets. The fellow boasted of having slain over one hundred cat-birds that season." That the small boy is recognized in other countries as a THE CONSERVATION OF BIRDS. 259 prime factor in decrease in birds is shown by the recent rec- ommendation of a committee of the British Association for the Advancement of Science that particular pains should be taken to instruct the youth concerning the birds that should be protected. Enormous numbers of birds are sacrificed annually for millinery purposes. There is an opinion prevalent that the birds worn on women's hats in America are largely derived from the faunas of tropical regions. Some justification of this is found in the impossible colors of all sorts assumed by the plainest songsters when they have passed through the dye-pot of the preparator. But there can be no question that an immense quantity of bird life has been destroyed in the United States to gratify the caprice of fashion, the birds thus killed being very largely used within our own borders, while many are exported to Paris and other European cities. The evidence on this point is abundantly sufficient ; some of it may properly be introduced here, as the subject is one which is greatly in need of more general knowledge on the part of the public. An editorial article in the Forest and Sfreain a few^ years ago mentions a dealer who, during a three months' trip to tlie coast of South Carolina, prepared no less than eleven thousand and eighteen bird-skins. A considerable number of the birds killed were, of course, too much mutilated for preparation, so that the total number of slain w^ould be much greater than the number given. The person referred to states that he handles on an average thirty thousand bird-skins a year, of whicli the greater part are cut up (or millinery })urposes. About the same time, according to a writer in the Baltimore Sun, a New York milliner visited Cobb's Island, off the coast of Virginia, to get material to fill a foreign order for forty thou- sand bird-skins. She hired people to kill the birds, for which she paid ten cents apiece. The birds conqirised in this whole- sale slaughter were mainly gulls and terns, or sea-swallows, 260 BIRDS IN THEIR RELATIONS TO MAN. of which large numbers of several species could formerly be found on this island. But now only a few of these graceful birds remain, and the pot-hunters, or rather skin-hunters, have to go some distance to carry on their cruel occupation. If we consider that with each old bird killed — the killing is done mainly in the breeding season, as only adult birds have suitable plumage — many young, unable to care for themselves, die of starvation, this wholesale slaughter appears the more infamous and criminal. Further south, in Florida and along the Gulf coast, the herons and egrets have been ruthlessly persecuted for their plumage. The heronries, where enormous numbers of these graceful birds formerly bred unmolested, have been largely broken up, and only the shyness of those remaining enables them to survive. In a paper read before the World's Congress of Ornithologists, at Chicago, in 1893, Mr. T. Gilbert Pearson describes a visit to a locality known as Horse Hummock, Florida. In 1888 he found several hundred pairs of little blue, snowy, Louisiana, and black-crowned night-herons at a heronry there. Three years later, when he returned to the spot, silence reigned, and only fragments of nests and bleaching bones were to be seen. Plume-hunters had either killed or driven off the entire community. Concerning another heronry Mr. Pearson writes as follows : "A few miles north of Waldo, in the flat pine region, our party came one day upon a little swamp where we had been told herons bred in numbers. Upon approaching the place the screams of young birds reached our ears. The cause of this soon became apparent by the buzzing of green flies and the heaps of dead herons festering in the sun, the back of each bird raw and bleeding. The smouldering embers of a camp-fire bore witness to the recent presence of the plume-hunter. Under a bunch of grass a dead heron was discovered from whose back the plumes had not been taken. The ground was still moist with its blood, showing that death had not long before taken place. THE CONSERVATION OF BIRDS. 261 The dirt had been beaten smooth with its wings ; its neck was arched ; feathers on its head were raised, and its bill was buried in the blood-clotted feathers of its breast, where a gap- ping wound showed that a leaden missile struck. It was an awful picture of pain. Sorely wounded, this heron had crawled away and, after enduring hours of agony, had died, the victim of a foolish fashion. Young herons had been left by scores in the nests to perish from exposure and starvation. These little sufferers, too weak to rise, reached their heads over the nests and faintly called for food, which the dead mothers could never bring." This slaughter of the innocents was by no means confined to our Southern States. During four months seventy thousand bird-skins were supplied to the New York trade by one Long Island village. " On the coast-line of Long Island," wrote Mr. William Dutcher, not long ago, " the slaughter has been carried on to such a degree that, where, a few years since, thousands and thousands of terns were gracefully sailing over the surf-beaten shore and the wind-rippled bays, now one is rarely to be seen." Land-birds of all sorts have also suffered in a similar way, both on Long Island and in adjacent locali- ties in New Jersey. Nor have the interior regions of the United States escaped the visits of the milliner's agent. An Indianapolis taxidermist is on record with the statement that in 1895 there were shipped from that city five thousand bird- skins collected in the Ohio Valley. He adds that "no county in the State is free from the ornithological murderer," and prophesies that birds will soon become very scarce in the State. These isolated examples can only suggest the enormous number of birds sacrificed on the altar of fashion. The uni- versal use of birds for millinery purposes bears sufficient testimony to the fact. Yet it is probable that most women who follow the fashion seldom appreciate the sutfering and the economic losses which it involves. 262 BIRDS IN THEIR RELATIONS TO MAN. A few years ago tlie Committee on Bird Protection of the American Ornithologist's Union issued an appeal in which occurs this paragraph : " So long as the demand continues, the supply will come. Law of itself can he of little, perhaps of no ultimate avail. It may give check, but this tide of destruction it is powerless to stay. The demand will be met ; the offenders will find it worth while to dare the law. Only one thing will stop the cruelty, — the disapprobation of fashion. It is our women who hold the great power. Let our women say the word, and hundreds of thousands of birds' lives will be preserved every year. And until woman does use her influence it is vain to hope that this nameless sacrifice will cease until it has worked out its own end and the birds are gone." The destruction of the smaller birds for food is much greater than is commonly supposed. It is due not so much to the demand created by native white Americans, as by the foreigners in the North and negroes in the South. During the migrations to and from the southern regions, enormous num- bers of birds which are commonly considered non-edible are killed for food. In the larger cities hundreds of such victims were formerly sold. Besides the reed-birds, robins, meadow- larks, and blackbirds that one would expect might be found, there were woodpeckers, thrushes, sparrows, warblers, wax- wings, and vireos. An interesting example has been reported by Mr. Walter E. Bryant in the case of the " reed-birds " of San Francisco markets. " For years there have been exposed for sale small California birds, picked, and six of them ranged side by side with a skewer running through them. These are sold as "reed-birds," though, of course, they are not the Eastern bobolink, Avhich does not occur in California. They are most commonly the horned lark (Ofocoris)^ but there may often be found on the skewers housefinches, goldfinches, various sparrows (except the English variety), blackbirds, and sand-pipers. Many thousands of birds are thus destroyed THE CONSERVATION OF BIRDS. 263 annually." The tendency, as Mr. Bryant says, is steadily "to increase in severity, and it has long since arrived at that stage of importance which should bring' it to the notice of the authorities interested in bird protection." In the South all sorts of small birds appeared in the city markets. In a statement concerning the destruction of small birds in the vicinity of New Orleans, Professor Nehrling says : " There is scarcely a hotel in New Orleans where small birds do not form an item on the bill of fare. At certain seasons the robin, wood-thrush, thrasher, olive-backed thrush, hermit- thrush, chewink, flicker, and many of our beautiful sparrows form the bulk of the victims ; but cat-birds, carchnals, and almost all small birds, even swallows^ can be found in the markets." ^ A few small birds have ranked as game more or less gener- ally. Of these the bobolink is one. Although one of the best-beloved birds in the North, where it is given all the pro- tection accorded to any bird, in the Middle States it is killed in enormous numbers during the autumnal migration. To one familiar with the bobolink's liquid melody and parental devotion such slaughter seems a sacrilege. In the rice-grow- ing regions along the Carolina coast, bobolinks are veritable pests and as such are destroyed. Robins are also killed in the Southern States during the winter. A notorious example of robin slaughter is that of a consignment of twenty-seven hundred in one lot received by a Washington, D. C, dealer in the spring of 1897. During their stay in the South they occupy regular " roosts," where they assemble at nightfall by thousands, and it is at these " roosts" that most of the slaughter is accomplished. Flickers, meadow-larks, and blackbirds have been quite generally slain the country over, especially by those unable to kill anything biggor; hiil among Inic sportsmen they have See W. T. Iloiniulay, iM Ami. Repl. N. Y. Zo«.l. Soc, p. 80, 1898. 264 BIRDS IN THEIR RELATIONS TO MAN. long been on the " retired list." Birds of this class have been gradually taken from the game lists in the several States — a ten- dency culminating in the Migratory Bird Act passed by Congress in 1913. This act makes a continuous closed season on mi- gratory insectivorous birds, excepting the bobolink or reed-bird, which maybe hunted from September 1 to October 31 in cer- tain of the Atlantic States. The segregating habit of sea-birds at certain breeding places, so advantageous to plume-hunters, is not less so to "eggers," nor less fatal to the birds. Audubon, in his Ornithological Biography, devotes a chapter to " eggers," with whom he came in contact on his Labrador exploration. Their ruthless invasion of the barren islands inhabited by countless murres and gulls, resulting in the loss of every egg that could be dis- covered, all summer long, evidently aroused the displeasure of the great naturalist. Even down to a few years ago, when Dominion laws put a stop to it, egging was conthmed on the islands off New- Brunswick and northward. Tlie eggs were brought off by boat-loads and sold for various purposes. Wherever colonies of sea-birds assemble to breed along our Eastern coast, the practice of turning the eggs to commercial use has been in vogue. The eggs of the laughing gull (Lams atricille) are an esteemed delicacy in Virginia. The gulls, terns, and herons, which formerly bred in immense numbers along the coasts of Florida and Texas, have been subject to the same blasting influence. An article ^ by Mr. H. W. Elliott gives an idea of the abundance of eggs and the wholesale manner in which they have been gathered in the Pacific. Mr. Elliott states that when he visited Walrus Island, in Behriug Sea, in July, 1872, six men loaded a four-ton boat with murre eggs in less than six hours. Concerning egging in California, Dr. T. S. Palmer writes:^ "A still more striking example of wholesale 1 The Auk, vol. v. p. 377. -' Yearbook, Dept. ..1" Aur. f.-r IS'Hi, p. i>71, THE CONSERVATION OF BIRDS. 265 egg-collecting, and probably the most important one in the United States, from a financial stand-point, is that of the Faral- lones. These islands, or rather rocks, situated on the coast of California, thirty miles west of the Golden Gate, are the breed- ing-grounds of myriads of sea-birds, chiefly western gulls (^Larus occidentaUs) and murres, or California guillemots {Uria troth Calif ornica). For nearly iifty years murre eggs were collected here and shipped to San Francisco market, where they found a ready sale at from twelve to twenty cents a dozen, a price only a little less than that of hens' eggs. During the season, which lasted about two months, beginning near the middle of May, the eggs Avere shipped regularly once or twdce a week. The main crop was gathered on South Faral- lone, the principal island, and mainly from the ' great rookery' at the w^est end. The birds lay only one e^^ wiiich is deposited on the bare rock. When the season opened the men went over the ground and broke all the eggs in sight, so as to avoid taking any that Avere not perfectly fresh. The ground was then gone over every day, and the eggs Avere systematically picked up and shipped to market. The business AA^as in the hands of Italians and Greeks, who Avere also engaged in fishing, and, although a dozen or fifteen ' eggers' Avere employed on the islands, the number of eggs gathered Avas simply enormous. It is said that in 1854 more than five hundred thousand eggs Avere sold in less than tw^o months, and that between 1850 and 1856 three or four mill- ions Avere taken to San Francisco. . . . Since then the value of the eggs has declined, and the number has fallen off con- siderably. In 1884 there Avere gathered three hundred thou- sand, in 1896 about one hundred and eight thousand, Avhile in 1896 the crop was reduced to a little less than iiinely-tAVo thousand." As a cause of reduction in the number of sea-birds, egging undoubtedly is entitled to first place. Millinery shooting, though e(|ually destrnclivc in oixTation, was Ix'^ini al a date. 266 BIRDS IN THEIR RELATIONS TO MAN. so comparatively recent that, wicked as it admittedly is, it must be given second rank. For a long time all birds not used for food were ignored by the American people. Before there was a demand for their feathers and skins they were simply let alone. But when game-birds became scarce, and many foreign hnmi- grants, accustomed abroad to eating small birds, had come to our shores, and rampant fashion had set bird plumes among her gods, destruction began. All the serious dangers that beset the birds, at least those of human origin, have been operating only a comparatively short time. Then, again, it is only a few years since the food habits of such birds have been well understood. In view of all this, it is not strange that protective laws were late in making their appearance on our statute-books. Although game-birds were protected by law early in the nineteenth century, it was in 1850 that "small and harmless birds'' were given a legal standhig. In that year both Connecticut and New Jersey protected most of the com- mon small birds and their eggs by fixing a line for each bird or egg destroyed. Other States gradually followed suit, but in fourteen years only twelve States and the District of Columbia had adopted such laws. It was not long, however, before bird-slaughter became notorious, and then legislation quickly became general. "Insectivorous and song-birds" was the term often employed in framing these laws ; but that term was too loose and narrow. The slaughter of plume-birds led to their protection in Florida and Texas, where it was espe- cially severe, and by degrees they have come to be included in the number protected by many States. Even birds of prey, since it has been found that there are only half a dozen injurious species out of the whole family — or, rather, so much of it as is found in the United Slates, numbering about ninety — have come in for statutory shelter in several States. There is a deeply-rooted i)rejudice against them, however, that can- not be overcome in one generation, even by ligures ; the acts THE CONSERVATION OF BIRDS. '207 of the evil few have so blackened the n^pulatioii of the whole family, that it is not [probable that hawks and owls will be protected generally or specifically in most States for a long time to come. Few States grant protection to the whole tribe. Some protect all but " chicken-hawks." One or two protect fish-hawks. Several States have prescribed fines for killing bald eagles. The turkey buzzards {Cathartes aura), which prefer carrion to freshly-killed meat, are useful as scav- engers and are protected in the District of Columbia and in the Southern States. They ought to be protected wherever they occur. Besides birds of prey there are a number of other birds to which several States have thus far denied protection. Of such are the grain-eating birds, — crows, blackbirds, etc.; those which live upon fish, — loons, auks, mergansers, herons, and kingfishers ; and English sparrows. The last-named is the one most generally condemned ; only a few States have exempted fish-eating birds from protection, and less than half have announced a prejudice against crows and blackbirds. Legislation })rimarily intended for game has in a few instances afforded protection to all birds. Laws prohibithig shooting on Sunday and those requiring gun licenses are of this sort. Speak- ing of gun licenses, the protection of non-game-birds is the only reason that can be logically urged in their favor. The declara- tion that game is the property of the State is the foundation of all game legislation. That all citizens of the State have equal right to it must be conceded. A game law establishing a gun license discriminates against the poor sportsman and in favor of the rich one. On the other hand, a gun license re- quirement would undoubtedly delay the day when precocious youngsters go forth with two-dollar guns until many of them, at least, are old enough to be out of the bird-killing stage. In tlip vicinity of some of our larger cities trapping native song-birds to sell as i)ets has been carried on to such an extent that several States have prohibited it by law, so they 268 BIRDS IN THEIR RELATIONS TO MAN. may neither be captured nor kept in captivity. Other States •specify what birds may be caged. Whether birds are caged or not, so long as they are not subject to traffic, is a matter of no importance to birds in general. The few taken from the Avild state usually prove good missionaries. People that keep a tame bird a year or two are usually friendly to the race thereafter. Although every State and the Territory of Alaska has its bird law, there is a great lack of uniformity among the differ- ent States, and many of the laws are very incomplete. Their enforcement is usually left to State or county officials, gener- ally to game wardens or commissioners. Offences that do not come directly to their notice are rarely heard of, for the reason that most persons, even though favorable to bird pro- tection, dislike to report the misdeeds of their neighbors. The utility of birds and the causes and extent of decrease among them are so little understood by the general public that there is no popular interest either in making or enforcing laws for their preservation. So far as law-making is con- cerned, it is easy as compared with the task of preventing law-breaking; but even law-making — adequate law-making — has proved uphill work. Protection should be uniform, because most of our birds cover vast areas. Federal legisla- tion prohibiting interstate traffic in wild bird plumage, and the Migratory Bird Act, protecting migratory insectivorous birds, like the Lacey Act, meet the requirements more quickly and effectively than State laws. To meet the need of uniformity, and at the same time to suggest a safe, intelligent measure^ the Committee on Bird Protection of the American Ornithologists' Union have prepared an act which has already been adopted in its main features by several States. At this time it appears probable that, through the efforts of the ornithologists and others inter- ested in protecting birds, this proposed act will ultimately be the basis of protective laws throughout the Union. A copy THE COXSERVATIOX OF BIRDS. 269 of it, which is an amended form of the first draft taken from Bulletin No. 12, United States Department of Agriculture, Division of Biological Survey, page 48, may be found in the Appendix of this book. But laws are hardly more than " first-aid'' instruments, — superficial, and not certain. They are framed and caused to be enacted by a few specialists, who instruct the legislation committee having jurisdiction over such bills, but are notable to reach the people whom the laws are to govern. To the majority the call for protective laws is not understood, if, indeed, the laws themselves are known. Now that adequate statutes are either enacted or may reasonably be exi)ected very soon, it remains to scatter information about birds every- where, so that laws may be respected, or perhaps become unnecessary. Putting bird protection on a moral basis is a good deal like planting pears, — the returns will be slow in coming, but are certain to come in time. There is no portion of the whole realm of natural history more attractive than birds. People are always to be found who are glad to read or hear about them. Dissemination of facts about birds will do more for their lasting benefit than anything else, and it is in this line that those interested in their conservation should work. There must be lectures, short articles of a popular nature in newspapers and magazines, distribution of government and other publications relating to birds, posting bird laws in con- spicuous places, and, most important of all, systematic bird work in public schools. The importance of engaging the interest of our youtli in birds cannot be over-estimated. It results in a doubh' beiietit, for the birds will be lield in higher esteem and the chihh'en will become possessed of a source of lasting pleasure. The nest-robbing, bird-shooting boy and the feather-wearing girl may be made friends and allies of the birds at an expenditure of not over fifteen minutes of school time a week. Fortu- nately many teachers have lately Uikcn up tlie study of birds 270 BIRDS IN THEIR RELATIONS TO MAN. as a recreation, and thus have been led to bring it into school. A Bird Day is celebrated in many schools, and in at least three States Bird Day is combined with Arbor Day, and appointed by executive proclamation to be observed in schools by appro- priate exercises. While the results of school work are mostly as remote from the application as youth is from maturity, they ought not to be wholly so. As has already been noted, one of the greatest afflictions endured by birds is the nest-robbing small boy. Hunting birds' nests is apparently an original sin, born in the flesh and bound to crop out. Properly handled, it need be neither condoned nor condemned. The considerate teacher will take the bull by the horns by asking his pupils to find nests. He wdll require an account at stated intervals of the position and architecture of nests, the number and appearance of eggs, period of incubation, and length of time the young remain in the nest. The short-sighted ])olicy of taking eggs will thus be overcome. There should be no honor in failure. None should receive credit Avho are not able to report the young safely on the wing. Of course the teacher should have a lively interest in the niatter himself, and be able to advise in many ways, but this much granted, the i)lan will work.^ ^ In this school work The Bird Calendar, hy Clarence Moores Weed, will be found useful. It enables the pupil to keep his record clearly and systematically. It is ])ul)lished by Rand, McNally &: Co., Chicago. CHAPTER XXII. THE CONSERVATION OF BIRDS (Concluded). II. THE GAME-BIRDS. The term game-birds is at present held to comprise the fol- lowing four orders of birds : An.^eres, ducks, geese, and swans ; Falxdicohv, cranes, rails, coots, and gallinules ; LbnU-ohv, shore birds ; GaUhice, grouse and quail. The members of the order Cohimhce^ pigeons and doves, have been generally considered game, and still are by many ; but these birds have become so scarce that it is plainly unwise to treat them as game any longer. For the same reason certain species belonging to the orders above named should be taken from the game list, tem- porarily at least. The cranes are sucli birds. Flickers, larks, robins, and similar birds, formerly called game, as we have seen, by right are game no longer. Either by decrease or by a demonstrated superior living value the accepted list of game- birds has been growing shorter. It is the purpose of this chapter to find the cause and trace the course of this tendency. Prior to the settlement of America by the whites, and, indeed, for many years after it, the game-bird problem was wholly in the destructive phase. How could enough l)irds be secured to satisfy bodily needs ? Avas the sum of it. xVfter a steadily-increasing drain for many years, we find ourselves confronted by a different phase, not destructive, but consc^rva- tive. The (picstion now stands. How can cxtcriiiinatioii be prevented ? Al)()riginal weapons were so crude and furred animals so much mon^ desirable on account of their skins that birds were not seriously persecuted ])y the red men. The pioneers were better equipped. Like the Indians, they depended on game for their meat supply, and early appreciated the sa})id ((ualities •_>71 THE CONSERVATION OF BIRDS. 273 of our native wild fowl. Birds were abundant in those days ; powder and shot were too dear to be expended on what could not be put to a good use, so we may be assured that the early settlers did not abuse their privileges. Necessity made man a destroyer of life. Bodily demands first sent him abroad to match human courage against brute ferocity, human patience against brute endurance, human cun- ning against brute sagacity. He found the excitement of the chase no less agreeable than its products. Hope and fear and victorious exultation combined to fill the hunter's breast with enthusiasm for his pursuit. The peculiar savors of Avild meat were sweet to his palate. What w^onder, then, that the red man declined to till the ground or that the fathers failed to lay aside the gun when it was no longer needed to supply the family larder. These two motives — appetite and love of sport — are the roots of the whole matter, and they must be the basis of our investigation. Let us see what each has contributed to bring about the present depletion of game-birds ; let us compare their merits, ethical and practical. As the land became cleared of forests the range of wild creatures was correspondingly restricted, and it was no longer possible for every man to supply his table with their flesh. There was no alternative but to use that of domestic animals in their place. Thus scarcity long since relegated all sorts of game from common fare, but it has ever been held in high esteem as a luxury with those able to procure it. The division of labor that gradually developed produced in turn the itiner- ant butcher and the market-man. The art of killing and the art of selling were divorced. The market-man gives employ- ment not only to butcher but to a host of others who contribute to the supply of necessities and luxuries that he handles. By combining energy, wealth, and science he has laid under con- tribution every land, eliminated distance, and defied alike climate and season. It is largely to his enterprise that we 18 274 BIRDS IN THEIR RELATIONS TO MAN. niusl ascribe the enormous quantities of game-ljirds thai are annually consumed by people who never saw one alive. At his call skilled huntsmen took the field, employing every means ingenuity could suggest to increase the catch. Nets, snares, traps, decoys, and ponderous guns were in constant use. For years professional hunters slaughtered, dealers handled, and gluttons gobbled without reason or restraint. There could be but one result : wild fowl have become scarce. Gunners no longer return at night with more birds than they can carry ; not seldom they come in empty-handed. But the millionaire makes up the shortage by paying higher prices. When a pair of canvas-backs bring a five-dollar note there is still money in shooting ducks. The same lavish fancy that prompts a rich gourmand to buy high-priced ducks prompts him to spend an equal sum for a box of strawberries out of season. The ducks are actually not finer than others of less repute ; the berries are not sweeter nor better-flavored than those he buys in spring at ten cents a box. His purchases are made without regard either to cost or intrinsic worth. He has reached a point where gratification outweighs money. But let us see the difference to us whether he spends it for berries or for ducks. When he buys berries he pays the gardener a special price for a special kind of skill and for maintaining an expensive establishment a fair recom- pense. The fruit is as truly the sole property of the horti- culturist as is the money the sole property of the purchaser. The transaction is legitimate. Now as to ducks. The gunner receives pay for skill and toil, as in tlie other case ; but the birds are his only by an acquisition not wholly above question. He has spent nothing on their nurture. He disposes of what we have as clear a title to as he if we would but make it good by scouring the marshes. Such a tith^ may not be very strong, but it has a certain validity nevertheless. As a democratic people, there is but one light in which we can regard game, — that is, as public property. If there were an inexhaustible THE CONSERVATION OF BIRDS. 275 supply there would be no ground for conflict between com- mercial and private interests ; but the supply is already alarm- ingly diminished, and we cannot doubt that traffic has been a large factor in makuig it so. When this country was tirst settled predaceous animals were troublesome. Bounties were offered for their scalps. For the most })art tliey are now extinct in the older localities. A price on the heads of hawks has reduced them to absolute scarcity in most parts of the East. It was put there for that purpose, and there is general gratification at the success of the plan. Who will contend that a price on a bird's body is likely to prove any less fatal to the bird, as a species, than if it were a premium on heads ? Various persons at different times have advanced arguments in defence of selling game, and at the same time have offered plausible advice as to how it might be done without endangering the stock. It has generally turned out that a personal interest lay at the bottom of such advo- cacy ; it might be a share in a cold-storage plant or a private game preserve that needed more freedom in management to become profitable. So long as there is a money value on game-birds, so long will there be a standing army of gunners harrying hill and dale, marsh and shore, — a shiftless, irre- sponsible company, who prefer the excitement of the hunt, although coupled with precarious returns, to regular employ- ment and a certain wage, — shooting without mercy, insatiate. Although America cannot boast of so large a variety of quadrupeds as the Old World, her wild fowl are unexcelled in variety, numbers, or gastronomic qualities. Persons expert in handling a gun Hud I hem incomparable as a source of sport. No amount of the smaller four-footed game can bring to the heart of the true sportsman the satisfaction he feels when he stops the headlong flight of a grouse or duck. Hunting has always had many devotees who have followed it simply for ph^asure. To l)e a successful hunter of wild fowl one nuist have a lash' for il. keen senses, and no mean skill. 276 BIRDS IN THEIR RELATIONS TO MAN. To such an one it is a prime diversion. The days allotted to it are landmarks in anticipation and remembrance. Thoughts of autumn keep a multitude contentedly at the plow, the bench, and the desk, resisting the appeals of spring and the torrid oppression of summer. For most men there is no pleasure in the sight of flowing blood or broken bones or gaping wounds or glazing eyes. It is not these concomitants of death nor death itself that are enjoyed. Enticement afield lies rather in the fortunes of chance and the exercise of ability, in the thousand delights to eye and ear in the haunts of nature — woods, water, busy insects, flitting birds, the gorgeous color- ing of autumn leaves, shy plants that blossom only in the shade. Chasing the quarry is but a string on which these things are strung. Grief bids farewell, care and melancholy go away, when one turns nimrod, as naturally as hunger follows fasting or sleep the labor of the day. With many, perhaps the majority, who shoot birds, sport is the main thing ; the game, after it is secured, being secondary, — hardly more than incidental. The diversion of mind, the increased vigor, the excitement at the critical moment, and a reasonable number of hits are sufficient returns for all the discomforts endured. The tender, woodsy-savored breasts at supper, to crown the day, are perquisites. But, unfortunately, there are men among the legion included under the title of sportsmen, as distinguished from market-gunners, who have never learned the virtue of moderation. They are never sat- isfied ; they cannot kill enough. No matter how many birds they see or how little use they may have for them, they kill and kill, so long as any are in sight or there is a shot in the locker. The term •• game-hog," which has been applied to this sort of a sportsman, is pat. His place is at the bottom of the shooting list. The market-gunner has a poor business, but he has at least a tangible excuse for killing all he can. For the " game-hog" there is no extenuation, unless we credit him witli a weak mind. THE CONSERVATION OF BIRDS. t i The 11 umber of sportsmen has constantly increased. This happens mainly as a result of increased population, though it has been assisted by modern inventions. Improvements in fire-arms have made successful hunting more sure. Railroads have penetrated wilder lands and afford easy facilities for reaching good grounds that otherwise would be inaccessible to the average gunner. When we reflect that game-birds showed a diminution in numbers a hundred years ago, it is a wonder that, with the increasing forces working against them, there are any left. So prevalent is the hunting spirit that, as in other branches of human interest, fraterni- ties have been formed. Sportsmen's clubs and sportsmen's leagues are many. Newspaper and magazine publishers cater to sportsmen by devoting more or less space to sporting news. Wealthy men, fond of shooting, club together, gain control of favorite game resorts by purchase or lease, and erect expensive houses thereon, in order that they may not forego home com- forts while engaged in shooting. Along the coast and on the borders of the great lakes are many such tracts, held for duck and goose shooting. In the primeval woods are many others. Such conveniences attract men who otherwise would not care to endure camp-life, and thus add largely to the foes of game- birds. There is another side to this, however, which is impor- tant, for it may prove the salvation of the birds, — the men of wealth and influence are made aware of their scarcity. Their investments in club properties as well as their love for sport give them an incentive to try to mend matters. In a number of instances they have replenished their covers with imported birds. They establish rules to regulate shooting on their ter- ritory, they influence i)ublic sentiment by api)eals through the press, and direct legislation with a strong hand. There are many sportsmen, without property rights, in favor of adequate protection, who are ready to quit when they have killed a reasonable number of birds. Such men are the right sort of leaven ; they can preach the doctrine of conservation with 278 BIRDS IN THEIR RELATIONS TO MAN. effect, for they practise" it, and cannot be accused of seltish motives. As editors and contributors they have already awakened a wide-spread interest in the protection of game, and it is largely through their labors that protective laws have been spread on the statute-books of every State in the Union. In our examination of motives we have seen that, though differing in kind, they have worked together along the same line towards the same result. So far as effect goes, they have been practically a unit, and in tracing the progress of decrease need not be separated. It is when we consider preventive means that a distinction should be made between them. In the early days game Avas taken at all seasons and by every available means. The settlers were not in a condition to think of ultimate results, and their successors did not take the pains. For many years wild fowl were so plentiful that the idea that they might become scarce probably did not occur to people in general. To kill a female bird in spring virtually destroys a whole brood for a gain of one — a poor one at that. In spite of the plain improvidence of killing at all seasons, it was continued for generations after it was noticed that birds were growing less. So it was Avith traps, nets, and swivel-guns. As a specitic illustration of the results of inju- dicious killing and of the prevailing negligent spirit with which it was viewed, let us look at the history of New Hampshire. Being one of the older States, the history of its game is prac- tically a chronicle of that of other older States and a prophecy of that of the newer. New Hampshire was first settled in its southeast corner, near the sea, about the year 1623. Its forests were dense and its soil stubborn, so that its occupation was very gradual. In 1792 Jeremy Belknap published a history of the State, in which was given a list of its birds. Among them were four game-birds that no longer have a place there. They were the sand-hill crane, the heath-hen, the wild turkey, and the pas- senger pigeon. The crane was even then presumably rare, THE CONSERVATION OF BIRDS. 279 though at about the same time Samuel Williams wrote -of them as among the commonest water-birds of Vermont. Be that as it may, during the nineteenth century only one sand- hill crane is known to have been taken in New England. This accidental })ilgrim to the land of his forefathers was killed about 1896, near where New Hampshire was first settled. Heath-hens long since vanished from the State, and the only remnant of the race left in New England is among the dense brush-land of Martha's Vineyard, off the south coast of Massachusetts. The wild turkey has also dis- appeared. Nobody knows when the last one was killed. In Massachusetts they were occasionally seen down to 1847. It is to be sincerely regretted that such birds are gone, the turkey and grouse especially, for no finer game-birds exist the world over. But as a striking example of the effect of cease- less slaughter the wild pigeon is pre-eminent. Belknap, quoting from the journal of Richard Hazen, who surveyed the province line in 1741, says, "For three miles together the pigeons' nests were so thick that five hundred might have been told on the beech-trees at one time." Before the end of that century pigeons were greatly reduced, though still abundant. Persons now living remember when netting and shooting pigeons at "beds" was a connnon practice. They brought but a trifie per dozen, yet many men w^ere in the business of capturing them for market. The decrease was more and more rapid as years passed. By 1850 they were scarce. Twenty-five years later they were rare, and in ten years more not one was to be found. Ten years after their disappearance the State legislature passed a law pro- hibiting the killing of pigeons for a term of three years. But it is not \hv exterminated species alone that deserve attention; indeed, tliey are "spilt milk" and may as well be forgotten, unless we can turn tlieir fate t(j a<*c()niit in per[»elu- ating those that are left. The worst sulTerers in New Hamp- shire to-dav are the water-fowl and shore-birds, especially 280 BIRDS IN THEIR RELATIONS TO MAN. near the coast, where most of them are exclusively found. A conservative estimate of the average annual slaughter of water-fowl — ducks principally — on her eighteen miles of coast and adjacent brackish waters, is five thousand. Half that number are sometimes killed off a single promontory, — Boars Head, at Hampton Beach. The majority are shot for revenue only. The older hunters are unanimous in saying that all sorts of water-fowl are scarce compared with what they were fifty years ago. Of the myriads of plover, snipe, curlews, and sand-pipers that formerly thronged beach and marsh only a fraction remain. The number of gunners that follow them is so great and the area they frequent is so wide that any estimate of the yearly capture is hazardous. Birds have been killed faster than they could uiultiply. At first it was not realized, but it was known so long ago as Belknap wrote, for he relates that " some of our epicurean gentry" had already begun to fear for the ruffed grouse. Thanks to its peculiar habits, that royal bird still inhabits its native heath. In spite of the fact that the decrease was ap- prehended, it was more than fifty years before the mental inertia of the people was overcome sufficiently for them to take active measures to stay it. Three game-birds had suffered extinction and a fourth was on the brink Avhen the first step was taken. The first game laws enacted related to time and method of capture. Spring killing and trapping were the earliest prohibitions. Only a part of the permanent resident birds were given even this protection. As time went on the num- ber of protected birds and the period of their protection were gradually increased ; but it was something like forty years after the initial law before the game-birds found in the State were given a closed season. In spite of statutes regu- lating seasons and methods, it at length became apparent that the decrease Avas not wholly checked, and further measures were taken. It was made an offence to send dead grouse 281 282 BIRDS IN THEIR RELATIONS TO MAN. and Avoodcock and plover out of the State. Public opinion favorable to the protection of game has been steadily growing. A State game and fish conniiission, having game interests in charge, superintends the propagation and distribution of game and prosecutes offenders. This, in a nut-shell, is a history of game-bird relations in New Hampshire. In other States the story runs much the same. A pro- nounced falling off in the number of game-birds is acknowl- edged everywhere. Some States have been more prompt with measures to prevent it, some more tardy. New York passed a law protecting heath-hens in 1791, but so late as 1874 only twenty-four States and territories had game laws. At present every state offers some protection. They all prohibit market hunting or the sale of certain game birds ; and many prohibit export. Practically all require that non-resident hunters shall be licensed and in most States this law applies to residents as well, though to them licenses are issued at a nominal rate. In many States there are laws limiting the number of birds that may be killed by one person in a day. Although the need of game protection was a long time in im})ressing the public mind, when once aroused, the sentiment in its favor rapidly gained streni^th. There is scarcely a legislature that is not asked to do something to help it along. One of the greatest difficulties in the way of a general en- dorsement of, and respect for, game laws has been their lack of uniformity. One does not mind refraining so much when everybody else has to refrain, too ; but when he sees his neighbors doing what he is enjoined not to do, there is a temptation to rebel. When there is a variance in the laws of the adjoining States there is sure to be poaching near the boundary. One State allows spring shooting of water-fowl, the next prohibits it, yet they have a continuous coast-line or are separated by a river. There is Injustice when slaughter must cease at an arbitrary line which has no natural signifi- cance. Those who kill illegally under such circumstances THE CONSERVATION OF BIRDS. '28:^ always defend themselves on this ground, though it may not be the real cause of their crime. In spite of the fact that it cannot save them from punishment if they are prosecuted, it undoubtedly keeps down the number of complaints that reach official ears. Officials themselves are likely to give most of their attention to other parts of the State. As an example of non-uniformity take Iowa and her near- by neighbors north and south, Minnesota and Missouri. In 1901 the close season for ducks in low^a was April 15 to September 1 ; in Minnesota it was January 1 to September 1 ; and in Missouri April 1 to October 1. Iowa gunners were allowed to kill ducks six weeks longer than Missouri gunners, and thirteen w^eeks longer than Minnesota gun- ners. If ducks were permanent residents such discrepancy w^ould not matter, but the majority of them are migrants, exposed to fire from each of the three States in succession. The laws relating to other game-birds in these three States were no nearer alike. Neither Avere game laws of other con- tiguous States better in this respect. In the statement of close seasons in the different States and territories issued by the Department of Agriculture^ there w^ere not three succes- sive States with uniform law^s relating to a single game-bird, with the exception of Utah, Idaho, and Washington, which agreed in protecting grouse and prairie chickens. This con- dition of things was manifestly wTong, and so long as it con- tinued the laws in question were certain to be violated. Popular sentiment did not uphold them. It is not practicable to police every bit of w^oods, every stretch of water, every grain-field. If game laws do not meet the approval and have the hearty support of the masses, they are void. The palpable impropriety of prohibiting on one side oi a certain line what is openly and legally practiced on the other can lead to but one outcome — ^defiance.

In this, as in all movements involving numbers, there must be pioneers, — individuals to move first. There have been pioneers. New York was the first one. To-day there are all degrees of protection offered. In a few States it is nearly or quite up to the desires of those who have given the subject most thought. It now remains for others to get in line. A suggestion made by Mr. Charles Hallock, in an address to the National Game, Bird, and Fish Protective Association, in 1897, relative to uniform laws, is worthy of notice. He i)ro- posed a division of the United States into three districts which might readily adopt game laws of the same general tenor, if not actually identical. The original scheme of Mr. Hallock, some- what modified as to boundaries, was presented by Messrs. Palmer and Olds, of the Biological Survey, in Bulletin No. 16, United States Department of Agriculture, from which the map at the beginning of this chapter is taken. The Rocky Mountains form a natural barrier between the Northern and Pacific divi- sions, while the line between the Northern and Southern divisions is established with reference to climate. This plan, after being before the sporting public for sixteen years, finally materialized, in its main features, not as a series of uniform laws, but as an act of Congress, known as the Migratory Bird Act, the second federal law to protect game. An important piece of legislation in favor of birds is the Lacey Act, so called, a national law, approved May 25, 1900. By the provisions of this act the preservation, distribution, introduction, and restoration of game-birds and other birds is induced in the duties and powers of the Department of Agricul- ure. The Secretary of Agriculture is authorized to purchase and distribute such birds as may be required, subject to the laws of the various States and Territories ; and also from time to time to collect and publish useful information as to their propagation, uses, and preservation. The importation of for- eign wild animals and birds without a si)ecial i)ermit from the 286 BIRDS IN THEIR RELATIONS TO MAN. Secretary of Agriculture is made unlawful. The introduction of English sparrows and starlings is specially prohibited. This act also prohibits interstate commerce in the dead bodies of animals or birds, or parts thereof, Avhen killed contrary to the laws of the State or if the State prohibits their export. All birds, or parts thereof, when brought into a State are subject to the same law^s that would apply in case the birds were pro- duced in that State. The operation of this act has been very satisfactory. Federal officers have prosecuted offending hun- ters, dealers and cold storage companies with such vigor and firmness that market hunting for interstate traffic has been practically suspended. The numberless ducks and geese reared in the vast territory included in the Northern States, Canada and Alaska, follow definite routes in migrating and are concentrated in winter within a narrow strip along the Southern coasts. As a result of being persistently hunted in these congested areas, a steady decrease in their numbers became alarmingly evident in the North. The number of cranes, rails and shorebirds also fell off from the same cause. Hunters in the South not realizing, or indifferent to, the evil of unrestricted pursuit, were loth to forego even a part of their shooting. Those along the migra- tion routes, where the decrease was most evident, became divided into two factions; one, conservative, in favor of abol- ishing spring-shooting, the other, prodigal, against it. Each succeeding session of the legislatures in the various States was the scene of hard-fought struggles over this question. Finally the matter was taken to Congress, where, after much discus- sion, a bill known as the Migratory Bird Act was passed and approved in 1913. On the premise that all migratory birds that do not remain the entire year in any State are in the cus- tody of the United States this act established a daily closed season for all migratory game from sunset to sunrise ; a gen- eral five-year closed season for band-tailed pigeons, cranes, swans, curlews and all shorebirds excepting black-breasted THE CONSERVATIOX OF BIRDS. 287 and golden plovrrs, jacksnipe, woodcock and the greater and lesser yellowlegs ; a five-year closed season for woodduck in the Northern States from Maine to Minnesota and Kansas and in the three Pacific States ; for rails in Vermont and Califor- nia, and for woodcock in Illinois and Missouri. The Miss- issippi Eiver, between Minneapolis and Memphis, and the Missouri River, between Bismark and Nebraska City, were closed to all hunting indefinitely. As these rivers are main thoroughfares for migrants, the sections tlius set apart are of great importance as refuges as well as breeding grounds. By the provisions of this act the United States was divided, as a basis for uniformity, into a northern or breeding zone and a southern or wintering zone, somewhat after the plan sug- gested by Mr. Hallock (see pages 272 and 281). All spring shooting became illegal and open seasons were limited to from two to three and a half months. For rails, coots, gallinules and the five kinds of shorebirds remaining on the game list, the open season was from September 1 to December 16 in both zones ; for waterfowl it was from September 1 to De- cember 16 in the northern zone, and October 1 to January 16 in the southern ; for woodcock it was from October 1 to December 1 in the northern zone, and November 1 to January 1 in the southern. Exceptions to each of these regulations were made for a few States, as may be seen in the digest of this act in Appendix II. There is a diversity of opinion regarding tlie constitutionality of this act but there can be no question as to its beneficial effect if rigidly enforced. Besides the protection afforded by game laws, there is the method of establishing preserves where birds are either given complete immunity from slaughter or are carefully guarded from excessive depletion. The associations of wealthy sports- men that exist in various parts of the country, where they control much land, look after their game very carefully, as has already been stated. Such preserves are maintained at so large an expense that they can never become numerous enough to bo of a})pre(iable assistance in ropopulating the 288 BIRDS L\ THEIR RELATION TO MAN. woods. But it is perfectly feasible for owners of adjoining farms, if they are so minded, to combine their properties into preserves that would accomplish everything. A tract of land comprising ten or a dozen average farms, thus set apart by mutual consent as a section where no birds should be killed, would become a reservoir, the overflow from which would afford excellent sport in the surrounding region. Birds would not only become more abundant, but the danger of extermi- nation would be out of the question. In Bird Lore, June, 1901, Mr. Willard G. Van Name, of New Haven, Connecticut, gives an account of a preserve of this sort that has proved all that was hoped for it. This preserve, comprising between one and two square miles of farm- and woodland, is in the vicinity of New Haven. It was organized by Mr. E. Knight Sperry, of that city. Mr. Sperry first obtained permission to try the experiment from the seven or eight owners of tlie land, on condition that neither he nor they should shoot there, and that he should bear all expenses, while they were to enforce prohibition. The chief expense was for signs forbidding shooting. A few quail were turned loose each year, though it is now thought that was unneces- sary. Ruffed grouse were left to increase as they could. Small patches of wheat or buckwheat were sown to keep the quail from starving or wandering in search of food during the winter. Almost immediately an increase was noticed, and soon the birds became very abundant on the preserve, and now there is good shooting on the neighboring farms where formerly very few birds were to be had. The land-owners are so w^ell pleased with the plan that none have withdrawn from the compact, although they are all at liberty to do so at any time. It is well known .that both quail and grouse prefer to live either on or near cultivated land, where food is abundant. Farmers might easily combine in this way, thereby affording better sport for themselves, or increasing the attractions of THE CONSERVATION OF BIRDS. 289 their town fur oiilsido parties wlio iur (lie iinkv of the J)inls would be glad to come and pay well for shooting i)rivileges. In many sections the city boarder has become the farmer's best source of revenue. If he will protect his grouse and quail, he may sell them in the brush for more than he could realize by killing them himself and putting them in market, and at the same time extend his boarding season well into autumn. A city sportsman, whose time has a value, is glad to pay for a certainty of fmdhig game. Although game is held to be the property of the State rather than of the individual owning the land that supports it, he may still be the sole bene- ficiary if he will. He must obey the statutes, even on his own land, but he can profit in due season by his own restraint, for no one else can trespass on his premises if he forbids it. The plan of establishing preserves or sanctuaries for game has been extensively accepted by several States, and also by the federal government. For example, Pennsylvania has set aside a portion of the State lands for a game refuge. It is bounded by an encircling wire designed to show its limits to those approaching it without restraining the game in the least. Within this boundary no hunting is allowed. Since this refuge was established, the amount of game on and in the vicinity of it is said to have considerably increased. In Min- nesota, Colorado, Wyoming and several other States there are similar preserves. National parks, as the Yellowstone in Wyoming, the Glacier in Montana, and the Yosemite in Cali- fornia, national game preserves and monuments, as the Wichita Game Preserve and the Colorado National Monument, and a large number of national naval, military and bird reservations, aggregating millions of acres, have been designated as sanc- tuaries where game of all kinds shall not be molested. These places of refuge, preserved and kept inviolate by an enlight- ened public sentiment, will serve the double purpose of pre- venting the extinction of species and of acting as a source of supply to the surrounding regions. 290 BIRDS IX THEIR RELATIONS TO MAN. The statutory regulations framed to restore the former abundance of game birds, beginning with closed seasons and continuing with bag limits, hunting licenses, prohibition of sale, and so forth, while reasonably effective, have not accom- plished their purpose with the speed nor to the degree desired. With a view to supplementing their results, some interesting, as Avell as productive, experiments have been tried in artificial propagation of game birds. Professor C. F. Hodge reared in confinement the bobwhite and the ruffed grouse with great success, the eggs being hatched by bantams. The California valley quail has been bred in a similar manner, and there is no apparent reason why any of our native species of grouse or quail cannot be artificially propagated. Mr. H. K. Job states! that artificial foods may be given to young chicks of these species if they are lightly fed and allowed to range. The first food is usually egg, either hard boiled and mashed with bread or cracker crumbs or made into a c
