THE RELATIONS OF BIRDS TO MAN. Tue 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 which 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 delight 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 commonly repairing to the 1 me 2 BIRDS IN THEIR RELATIONS TO MAN. near-by orchard for that purpose. The bluebirds 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 chewinks 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 the trunk are borers of the bark, the sap-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 hosts of others. Set over against these destroyers are many feathered enemies: the woodpeckers, assisted by the nut- FEMALE RED-WINGED BLACKBIRD. THE RELATIONS OF BIRDS TO MAN. 3 hatches and creepers, look after the insects on and beneath the bark of both the trunk and branches; the chickadees and warblers and vireos and kinglets are always scrutinizing the 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 kingbird, pewee, and other fly-catchers, as well as to a-more limited de- gree the cedar-bird and bluebird, capture the in- sects that pass within their range of vision as_ they perch upon fence or stump or tree; the warblers and vireos catch those insects flying in the immediate 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- THE KINGBIRD. 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 birds 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- buildings mice and rats do much damage to grains, eggs, and poultry; in the grass-fields moles and meadow-mice are some- times injurious; in the or- chards rabbits often girdle young trees by gnawing the bark. Against these also the birds help us: the hawks and owls feed largely upon all these rodents, and per- form a great though 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 we 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 the few shortcomings of the birds which loom so large to many who see only one side of the picture. Fruit is pilfered by some of the birds, though in our region so few cherries and small fruits are raised and there is relatively so much wild fruit that the loss is of small THE YELLOW WARBLER.

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 hatred to the woodpeckers that resemble it,—the downy and the 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 who 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 walters 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, unfortunately, the inoffen- sive species generally have to pay the penalty for 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 sparrow, 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 dppreciation 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 RELATIONS OF BIRDS TO MAN. 7 supplying us with down by the eider-ducks; another, 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 fish by the presence of gulls, as along our Atlantic coast. Next in importance to the direct economic value of this bird life to our lowns-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 humming-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 human genius. There is also another relation the birds of Durham bear to its human inhabitants. In the woods everywhere ruffed 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 the bay wild ducks and wild geese are abundant during the fall migration. All of these birds afford those inhabitants who enjoy legitimate sport an opportunity for invigorating days of hunting, as well as a cer- 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, Beal, 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 him, a joint study of the whole 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-SPARROW. Photographed from life by Dr. R. W. Shufeldt. THE KINGBIRD. CHAPTER I. THE METHODS OF STUDYING THE FOOD OF BIRDS. Tue accurate determination of the feeding habits of birds must form the foundation of any adequate knowledge of their economic status. To determine these habits two principal methods are available: (1) the birds may be watched in their natural haunts and the food they take be observed as care- fully as possible; (2) the birds may be killed and the food found in their alimentary canals examined to determine its nature. A third method, that of observing the food prefer- ences of birds in captivity, is chiefly valuable in helping to determine the amount of food eaten by birds, although con- siderable information may thus be obtained also regarding their choice of food. The first of these methods may be readily employed in determining the varieties of vegetable food that adult birds eat, and in exceptional cases is of value in determining the animal food of such birds. It is of greatest value, however, when applied to the nestlings, especially in the modification of the method first successfully employed by Professor F. H. Herrick, and described in detail later in this chapter. To the majority who would learn at first hand what birds eat, field-work is the only sort that appeals. Only those with the genuine scientific spirit are willing to soil their fingers with dissection or to spend hours in identifying the contents of a single stomach, even though possessed of sufficient expe- rience to carry on such an investigation. Even in field-work an extensive knowledge of animals and plants is necessary if one would name half the objects he sees in birds’ bills. But while it is highly desirable to ascertain exactly what birds eat, it by no means follows that a person should wait until he has 9 10 BIRDS IN THEIR RELATIONS TO MAN. mastered botany, entomology, and kindred subjects, that will enter into his researches, before attempting to learn at least the general character of the food eaten by our various birds. To know whether a bird prefers insects or seeds is worth while, though the name of the insect or seed consumed may be beyond guessing at. The main thing, after all, in field- work, is to keep an attentive eye on the birds, to learn how to observe without frightening them, and to know when and where the different species feed. The study of food habits is not usually begun until after the student has gained a fair understanding of other habits that are more attractive to watch and oftener dwelt upon by ornithological writers. It is a sort of post-graduate course, so to speak,—another field into which the enthusiast, after covering the old run of species, distribution, migration, nests, eggs, etc., may enter if his enthusiasm holds out. There- fore it is taken for granted that whoever is inclined to inves- tigate the food of birds is equal to his undertaking from the bird side, if no more. What he may not know about the items of food in the beginning, he will become so anxious to find out that his stock of information will rapidly increase. If one is interested in birds, the food problem will afford a good ‘‘handle” for picking up an interest in other branches of natural history. For examining adult birds in the field, good vision and a note-book and pencil are the chief requisites, though an opera- or field-glass may often be used to advantage. War- blers, vireos, and other active birds that live by foraging may be quietly followed as they flit from tree to tree. In this way it is not difficult to discover the character of their food and about how much is consumed during a given interval of time. Now and then there will be favorable moments when it is possible to see for a certainty just what is taken. Cuckoos, kingfishers, flycatchers, and other birds that are more or less sedentary must be watched, an hour or two METHODS OF STUDYING THE FOOD OF BIRDS. 11 perhaps, from one position,—an occupation not nearly so irksome as it looks on paper. Wherever an abundance of some particular kind of food occurs, it is a good plan to sit down where you can see with- out being seen and wait for visitors. In this case your notes will take on a different look. Instead of having a bird’s name at the head and a list of food items beneath, you will have a food name at the top and the names of birds that partake in the columns below. Thus, you may sit on the shore and see what birds live on fish and what on mollusks. You may stroll across the fields at haying time and discover the birds that feed on the myriads of leaf-hoppers, grasshoppers, and ‘millers’ that take to wing at every step. So may you learn what birds are addicted to any seed or fruit that you may bring under observation. It is well to note in passing that birds are excellent judges of quality in fruits, for which reason it is well to see ‘which way the birds fly” before selecting a site for operations. In the laboratory birds may be kept alive and tested as to their preferences for different kinds of food, though such ex- periments are not likely to be very satisfactory, for the reason that birds in captivity quickly learn to relish things they would never taste in the wild state. A knowledge of the amount of food eaten by caged birds is of value, however, as whatever difference there may be between the quantity consumed in the wild and in the captive state is on the safe side. A prisoner cannot dispose of so much as the activity of a free bird demands. The determination of bird food by dissection requires an extensive outfit, if it is thoroughly done. There must be at hand good collections of botanical specimens, including seeds ; of insects, mollusks, fish, frogs, reptiles, birds, and small marn- mals,—everything, in short, likely to be eaten by a bird,—in order to name correctly the visceral contents. Even the bones of the smaller vertebrates will be necessary for identi- 12 BIRDS IN THEIR RELATIONS TO MAN. fying the food of hawks and owls. A simple magnifier will be needed constantly and at times there will be use for a com- pound microscope. Instead of examining each bird at the time of its capture, it is usually more convenient to remove the digestive tract, and, after attaching a numbered tag by means of thread, to put it into a jar of five per cent. formalin or eighty per cent. alcohol, where it may safely remain until enough have ac- cumulated for a day’s work. Viscera may be kept indefi- nitely if the preservative fluid is changed as often as it be- comes discolored. The number on the tag corresponds to one in the note-book, where are recorded the name of the bird, the date and place of capture, and any other data that may have a bearing on diet. When ready for the analysis, a stomach may be cut open with a pair of scissors or a scalpel, and the contents emptied, with a little water, on a piece of plain glass,—say, three by three inches, for any bird smaller than a flicker. If a dis- secting microscope be available, the magnifier may be managed more easily, and, furthermore, transmitted light or reflected light with a black or white background may be used at will. With a pair of sharp needles set in handles the mass may be. spread over the glass and assorted. Wings of insects may be unrolled and floated on the film of water so as to be identified as to family and often as to genus. By assembling the parts of insects or other food of the same kind into little piles, the relative amount of each may be estimated. Hawks, owls, crows, flycatchers, and certain other birds that devour indigestible matter, such as bones, the elytra of bee- tles, etc., regurgitate such matter in the form of compact pellets, generally at the roosting places. Insectivorous and 1 See The Common Crow, Bull. No. 6, U. 8. Dept. of Agr., Div. Orn. and Mam.; also Montgomery on the Food of Owls, Am. Nat., July, 1899, vol, xxxiii. pp. 563-6572. BOBOLINK APPROACHING NEST IN PAIL. NEARER HOME, METHODS OF STUDYING THE FOOD OF BIRDS. 13 fruit-eating birds do not digest their food so thoroughly but that its nature is apparent from the excreta. Wherever birds roost in numbers, pellets or excreta or both 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 difficult and on the whole more satisfactory. Both the kind and the quantity READY TO FEED. may be accurately determined without injuring so much as a feather. If the nest is on or near the ground, a small neutral-colored tent may be set up beside it as near as you please, into which you may retire, and, by watching the progress of affairs through a small “ peep-hole,” fill your note-book with an ac- count of the rations that are consumed. If on the ground the nest and young may be transferred to a sunken pail for better observation, as shown in the bobolink photographs herewith. It usually happens, however, that the nest is not in a position 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 off 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 when the nest has to be moved, unless the degrees of progress are made very short, there is danger of desertion if the moving is undertaken before the young are well covered with starting pinfeathers. Then they are able to move about and usually OUTFIT FOR PHOTOGRAPHING BIRDS IN NEST. to make sounds that attract the parent birds. At that time also parental devotion is at its full strength, and the old birds are willing to face dangers that 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 position without giving external evidence of it. 1 This method of controlling the nest and using a tent for concealment was first described in ‘‘The Home Life of Wild Birds,"’ by Professor F. H. Herrick, which see. METHODS OF STUDYING THE FOOD OF BIRDS. 15 It is set up early, so the birds may get accustomed to seeing it, and not taken down till the observation is completed. Sometimes several nests are brought one after another to the same site. In the illustration opposite there is a chipping- 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 birds, there is no objection to striking the tent every evening and pitching it again in the morning. At such short range there is generally no doubt as to the identity of every object that is brought to the nesl. 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 away, then go out and examine the young. Four times out of five you can tell what they have swallowed 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 the 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 per 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 the young al the same hour every day. Collect several excreta and find the average weight, also observe the average number voided per hour. The weight of excrement for the day plus 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 coat of albumen that it is not so objectionable to handle as might be supposed. It may be obtained at any time by taking the bird from the nest and keeping it out for a few minutes. In order to distinguish one nestling from another they may 16 BIRDS IN THEIR RELATIONS TO MAN. be marked either on the leg or on the side of the bill with a nitrate of silver pencil, which may be purchased at any drug store. There may be some difficulty in applying 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 weather, as well as of various living enemies. No one should remove a nest from its original site who is not willing to take every possible precaution to avoid a tragedy. HEAD OF BROWN THRASHER. THE BARN-OWL AND ITS PREY.

Wuen Columbus was making that eventful voyage which led to the discovery of the New World, he was cheered 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 hy others to which they 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 1808 began the publication of his splendid volumes on American Ornithology. As Dr. T.S. Palmer has well said,—in an admirable paper,’ of 1A Review of Economic Ornithology, Yearbook, Dept. Agr., 1899, pp. 259-292. ; 2 17 18 BIRDS IN THEIR RELATIONS-TO MAN. part of which the present chapter is necessarily a poor parallel, ’ __this work of Wilson’s laid the true foundation of ornithology in the United States. And it contained many references to the purely economic phases of bird life, showing again and again the value of different species as destroyers of insects. Before the century had run its first quarter the great Audubon was exploring the wilderness in all directions, making wonder- ful paintings of its bird inhabitants and drawing up excellent accounts of their ways and habits. The publication of his work began in 1827 and continued till 1839. He also made many references to feeding habits and economic values, as did Nuttall, whose volumes, published from 1832 to 1834, were largely based on the works of these two earlier naturalists. From 1850 onward the technical science of ornithology made wonderful strides, which it is no part of our present purpose to describe. But about this date various persons interested in agriculture began to see the value of birds as insect destroyers, realizing that the unchecked destruction of these feathered allies was leading to an alarming increase of insect pests. The agricultural journals and the reports of agricultural and horticultural societies began to publish many excellent articles, which showed careful observations and thoughtful consideration of the relation of birds to crop pro- duction. The titles of most of these papers will be found in the bibliography at the end of this book, so that there is no need for specific mention here. One by Wilson Flagg, however, published in the Report on the Agriculture of Massachusetts for 1861, is so remarkable that we cannot pass it by. Itis entitled ‘The Utility of Birds,” and is a general survey of the field which would do honor to a man to-day, after all the intervening years of study and discovery. It is based on the thesis distinctly stated in these words, which are italicized in the original article,—that each species of bird per- forms certain services'in the economy of nature, which cannot be so well accomplished by any other species. This paper was THE DEVELOPMENT OF ECONOMIC ORNITHOLOGY. 19 printed shortly after the publication of a remarkable article by Professor J. W. P. Jenks, in which an elaborate study of the food of the robin was recorded. In this study the modern method of examining the contents of the alimentary tract and estimating the ratios of the food elements found was em- ployed, apparently for the first time in any elaborate way. During the same year (1858) that Professor Jenks was making his investigations, another Massachusetts man, Professor D. Treadwell, made some remarkable observations upon the amount of food required by young robins, the results of which have often been quoted. During the decade from 1860 to 1870 there was a great deal of discussion regarding the influence of birds upon agri- culture. The transactions of the various agricultural and horticultural societies and the agricultural, horticultural, and entomological journals of this period contain frequent references to the subject. The statement by Dr. B. D. Walsh, the first State Entomologist of Illinois, that birds were of doubtful value because of the parasitic insects they devoured, led to much comment; this statement is discussed in Chapter VII. of the present work. It was during this period that Professor Samuel Aughey, of Nebraska, began his remarkable investigation of the relations of birds to outbreaks of Rocky Mountain locusts, the results of which are summarized in Chapter VI. herewith. These observations were not published, however, until near the close of the next decade,—1878. This was the most important study of the subject carried on during the decade from 1870 to 1880, although before the close of this period Professor S. A. Forbes, State Entomologist of Illinois and Director of the Illinois State Laboratory of Natural History, had begun the studies on which the classic papers published during the next decade were based. During the early years of the next decade Professor Forbes published several papers which may fairly be said to furnish the basis for the modern development 20 BIRDS IN THEIR RELATIONS TO MAN. of economic ornithology. The most important of these have the following titles: “The Food of Birds’ (1880) ; ‘On some Interactions of Organisms” (1880); ‘‘ Notes on Insectivorous Coleoptera” (1880) ; ‘*The Food Relations of the Carabidee and the Coccinellide” (1883); ‘The Regulative Action of Birds upon Insect Oscillations” (1883). These papers, by one of the most scholarly naturalists America has ever known, were as remarkable for their philosophic breadth of view as they were for the care with which the last detail was followed out. On the whole they still remain the most satisfactory papers upon economic ornithology that have been published. In 1882 Professor F. H. King, of Wisconsin, published an elaborate paper on the ‘‘Economic Relations of Wisconsin Birds,” and in 1886 Dr. B. H. Warren published a report upon the “Birds of Pennsylvania.” Each of these contained the results of many studies of bird food and was an important contribution to economic ornithology. During the latter half of that decade the subject of eco- nomic ornithology was taken up by the United States Depart- ment of Agriculture, and the story of the development of the subject since that time has been chiefly the story of the operations of the Division of Biological Survey. This work has been so well summarized by Dr. T. S. Palmer, Assistant Chief of the Survey, that we quote from his paper at consid- erable length. “One of the most important results of the organization of the American Ornithologists’ Union was the impetus given to the study of economic ornithology. Committees on the Eng- lish sparrow, bird migration, and geographical distribution were appointed at the first meeting, and elaborate investiga- tions were at once begun. The work, however, had been planned on such a large scale that it soon outgrew the re- sources of the committees, and at the second annual meeting of the union it was determined to present a memorial to Congress to secure an appropriation for continuing it. The THE DEVELOPMENT OF ECONOMIC ORNITHOLOGY. 21 relation of birds to agriculture is so intricate and the thorough study of their food so difficult, on account of the amount of time and material required, that investigations of this kind are ordinarily beyond the means of private individuals and are entitled to government support. In recognition of the importance of the work, Congress granted an appropriation of five thousand dollars, to be expended under the Division of Entomology of the Department of Agriculture, and on July 1, 1885, established a section of economic ornithology. Under the direction of Dr. C. Hart Merriam, investigations were outlined on a broad scale, to include the ‘food habits, distribution, and migration of North American birds and mammals in relation to agriculture, horticulture, and forestry.’ A year later the section became an independent Division, and in 1896 its name was changed by Congress to the broader title of Division of Biological Survey. ‘*PIRST PUBLICATIONS OF THE DIVISION. “Upon the organization of the Division of Ornithology and Mammalogy, the data collected by several of the committees of the American Ornithologists’ Union were turned over to it and formed the basis of its first two bulletins. The notes on distribution and migration of birds were published in 1888 under the title ‘ Bird Migration in the Mississippi Valley,’ and the report on ‘ The English Sparrow in America’ appeared in the following year. The latter report contained a full ac- count of the sparrow and its introduction into the United States, its depredations on crops, and recommendations for destroying it, or at least preventing its increase. Special at- tention was called to the desirability of legislation permitting the destruction of the bird. It is interesting to note that at the time the bulletin was issued the English sparrow was practically protected by law in twenty-two States, although Ohio and Michigan had taken steps to exterminate it, while now most of the States have withdrawn protection, and Illi- 22 BIRDS IN THEIR RELATIONS TO MAN. nois, Michigan, Ohio, and Utah have vainly attempted to de- stroy the pest under the bounty system. ‘“FUNCTIONS OF THE DiVISION FROM THE STAND-POINT OF ECONOMIC ORNITHOLOGY. “From the stand-point of economic ornithology the Divi- sion may be said to have three functions: (1) to determine as accurately as possible the food of birds of economic im- portance ; (2) to act as a court of appeal to investigate com- plaints concerning depredations of birds on crops; (3) to diffuse the results of its work and educate the public as to the value of birds. In studying birds’ food dependence is placed chiefly on examination of stomachs to ascertain what has been actually eaten. Stomachs are collected in different localities at all seasons and in sufficient numbers to show clearly the character of the food. The stomach contents are examined microscopically and identified by comparison with reference collections of seeds and insects. This laboratory examination is supplemented by experiment and field work. ‘S INVESTIGATIONS REGARDING SUPPOSED INJURIOUS BIRDS. “Species popularly considered injurious, such as hawks and owls, the crow, blackbirds, woodpeckers, and blue-jays, received attention first. A report on hawks and owls was undertaken by Dr. A. K. Fisher, one on the crow by Professor W. B. Barrows, assisted by Mr. E. A. Schwarz in the identi- fication of insect material, while the investigations on the crow blackbird, woodpeckers, and blue-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 the value of hawks and owls. About two thousand seven hundred stomachs of these birds were collected, the contents carefully examined, and the re- THE DEVELOPMENT OF ECONOMIC ORNITHOLOGY. 23 sults published in 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 found to be injurious, while several were shown to be beneficial. About the time the work was begun bounties on birds of prey were, or had recently been, offered by Colorado, Indiana, New Hampshire, Ohio, Pennsylvania, Virginia, and West Virginia. At present not only have all the important State bounties been withdrawn (the acts 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 during 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 hundred stomachs), published in 1895, showed that these birds were decidedly beneficial. Only one of the seven species of woodpeckers examined—the yellow- bellied—exhibited any questionable traits,—namely, a fond- 24 BIRDS IN THEIR RELATIONS TO MAN. ness for the sap and inner bark of trees. Of the forty or fifty birds, exclusive of hawks and owls, thus far investigated, the English sparrow is the only one which has been condemned. ‘CINVESTIGATIONS REGARDING BENEFICIAL BIRDS. ‘‘A number of species usually considered beneficial have also received attention. The Baltimore oriole, the meadow- lark, red-winged blackbird, rose-breasted grosbeak, cedar- bird, robin, bluebird, swallows, and several flycatchers have been studied by Professor Beal, and the shrikes, cat-bird, mocking-bird, brown thrasher, and house wren by Dr. Syl- vester D. Judd. One of the interesting facts brought out in studying the cat-bird was the discovery that some birds prefer wild to cultivated fruits, so that the latter may be protected by planting certain berry-bearing shrubs and trees, especially in regions where wild fruit is naturally scarce. The king- bird, frequently condemned as a destroyer of honey-bees, was shown to eat very few bees, and these mostly drones. On the other hand, it kills many of the destructive robber flies, and a large proportion of its food is made up of destructive insects, so that it must be regarded as decidedly beneficial. Recent investigations show less favorable results in the case of some other flycatchers, and indicate that the prevailing idea that all insectivorous birds are necessarily beneficial may require decided modification, and that there are birds which habitually feed on beneficial insects to such an extent as to lower their value to the farmer, if not to place them among the enemies of his crops. ‘‘ RESULTS OF FOURTEEN YEARS’ WORK. “As a result of fourteen years’ work, the Biological Survey has brought together a collection of about thirty-two thousand bird stomachs, of which some fourteen thousand have been examined. It has investigated about one hundred species (nearly half hawks and owls) and prepared the results for THE DEVELOPMENT OF ECONOMIC ORNITHOLOGY. 25 publication in the form of bulletins or special papers. 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 summaries, 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 pride. 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 progress of economic ornithology it is becoming more and more evident to careful students of the subject that much of the best work hereafter 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 obtained 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 studies 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 was 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. xxxi. pp. 892-397. 2 See ‘‘ Birds of a Maryland Farm,"’ Bulletin No. 17, Division of Bio- logical Survey.

A COMPREHENSIVE survey of the feeding habits of birds leads to the conclusion that the common terms vegetivorous and insectivorous have but a relative significance. They 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 Composite—supplies 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 similar food to the same hungry company. The ragweed, which springs up unbidden everywhere, is perhaps 27 28 BIRDS IN THEIR RELATIONS TO MAN. 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 Polygonacee—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, mullein, 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 Graminee also supply their share. Among them the pigeon and other grasses of the genus Setaria 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 the 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 VEGETABLE FOOD OF BIRDS. 29 Cultivated grains are consumed in varying quantities by a large number of birds, though 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 habitually 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 sparrows 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 owners 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 depredators 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 RELATIONS TO MAN. are enjoyed by goldfinches, and that English 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 important elements in bird food, because their tiny winged seeds are quite persistent, many of them cling- ing to the catkins throughout the winter. They offer an un- failing supply so long as they remain upon the trees, and are liberally patronized by the winter finches, redpolls, siskins, and cross-bills. Thesmall gray birch is levied upon in autumn by chipping and field sparrows, and in winter it becomes an es- pecial favorite with juncos, tree-sparrows, 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 happens that a severe drouth in August THE VEGETABLE FOOD OF BIRDS. 31 dries the stems of maple seeds before they have become woody, so that they are tough enough to withstand the blasts of autumn, and thus remain upon the trees indefinitely. Under these conditions the grosbeaks find life easy and never quit the neighborhood of trees thus laden until the last seed is plucked. If the ground is not covered with snow, they frequently 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 area few specialists, however, ‘endowed with an appe- tite for such seeds and an adequate apparatus 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 acute. Although most of the white-pine 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. Any of the seed eaters WHITE-WINGED CROSS-BILL. 32 BIRDS IN THEIR RELATIONS TO MAN. finding these strewn upon the ground seem ready to accept them, as are also the woodpeckers and the brown creepers, when fortune favors them with stray kernels in famine time. 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 woodpeckers seem to find it agreeable to sandwich 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 depend upon 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 basswood, are eaten to some extent by the grosbeaks and woodpeckers. There are a number of dry fruits intermediate between nuts and soft fruits which are of some consequence to birds THE VEGETABLE FOOD OF BIRDS. 33 on account of their persistence. The various sorts of sumach berries fall in this class. These berries remain throughout the winter as they grew, and during the season of want add materially to the food supply of northern birds. Ruffed grouse, crows, jays, woodpeckers, nuthatches, and chickadees frequently partake of them when the ground is covered with snow. Brown thrashers, cat-birds, mocking-birds, bluebirds, robins, and even kingbirds eat them at times, though prob- ably never to any considerable extent. It is interesting to CEDAR-BERRIES. note in passing that the berries of the poison-ivy and poison- sumach are eaten as freely as those of any other species of equal abundance. » The small hard berries of the red cedar and juniper con- tribute to the livelihood of practically the same company. They are especially sought by cedar-birds and are evidently enjoyed by purple finches, pine grosbeaks, and myrtle war- blers; the latter bird, however, depends in cold weather more upon bayberries than anything else. In fact, it gets its name from one of the vernacular names of the shrub that 3 34 BIRDS IN THEIR RELATIONS TO MAN. bears them,—wax-myrtle. Bayberries are also eaten by other winter birds and late migrants, much the same as sumach and cedar-berries are. : These dry fruits must be reckoned as necessities rather than luxuries in bird economy: except the bayberries, they are seldom eaten when more palatable fruit is to be had. THE MYRTLE WARBLER, Pulpy fruits, on the contrary, are evidently enjoyed by birds, for they form the main diet of many normally insec- tivorous birds just when insects are most abundant. Of the various plants, large and small, bearing pulpy fruits, those of the rose family (Rosacece) hold first place from our present THE VEGETABLE FOOD OF BIRDS. 35 point of view. Among the many kinds of fruit produced by this family the cherries are most important, as they are eaten by all birds accustomed to taking fruit of any sort and are to be had in unlimited quantity during more than two months in the year. The wild red cherry, which is the first to ripen, is least esteemed, though cedar-birds appear to find it quite satisfac- tory. Birds in general, however, eat these far more sparingly than they do the later varieties. Choke-cherries and black cherries form an appreciable percentage of the food of cedar- birds, thrushes, orioles, jays, crows, and grouse from the time the first choke-cherries begin to grow brown in midsummer until the rains and frosts of autumn have despoiled the black- cherry trees of the last of their shining loads. Grackles, fly- catchers, sparrows, woodpeckers, and pigeons assist to a lim- ited extent, but cedar-birds and robins are the most persistent devourers, with the flicker a close follower. The large num- bers of cherries consumed as well as the variety of birds involved doubtless depend somewhat on the fact that cherry- trees grow in all sorts of places. The shy grouse and the woodland thrushes, cat-birds, and thrashers are able to get plenty of them without being exposed to the dangers of open ground; while the familiar robins and cedar-birds, which pre- fer cleared land, find all they want by road-sides and pasture fences. Wild strawberries, raspberries, and blackberries are all dear to the avian palate. The first are not so largely eaten as the other two, for the reason that many birds which undoubtedly relish them do not like to hunt for them in the grass. Rasp- berries and blackberries are available to a larger number. Cat-birds, brown thrashers, and sparrows are at home in a brier patch and enjoy the fruits thereof. The ruffed grouse makes a regular practice of living in blackberry thickets while the fruit is on the vines and during that time feeds upon little else. The running blackberries, or dewberries, near the coast 36 BIRDS IN THEIR RELATIONS TO MAN. are frequently eaten by the larger shore-birds, such as the curlews and plovers. The shad-bush or service-berry, another member of the rose family, is of some value to birds, more especially as its fruit matures early. It is visited by the same group of birds that flock to the cherry-trees later in the season, but the quan- tities taken are not large. The fact that birds do not gorge themselves with the berries seems to be not through any fault of the berries, but rather because they ripen at a time when a more concentrated food is needed for the: prose- cution of vernal activities. When the nesting season is over and the year’s labor done, comes the time for relaxation, moulting, and a general rejuvenes- cence. Then fruit is in order: each bird accord- ing to its nature seeks its favorite; crows and jays ees prefer mast and go to the Sal Eto cae nut-trees ; sparrows loiter among the weed-thickened stubble; robins, cedar-birds, and a host with similar tastes gather at the cherry-trees. Although early fruits are more or less neglected, late varieties of ever so mean quality receive more attention. The berries of the mountain-ash, the last of the wild species of the rose family to be mentioned here, are among the latest maturing of the wild fruits. They are unpalatable to THE VEGETABLE FOOD .OF BIRDS. 37 our taste, but the rear guard of the southern-bound migrants eat them with apparent relish. Cedar-birds, robins, and other thrushes are especially fond of them. The shrubs belonging to the honeysuckle family (Capri- foliacece) produce a number of soft fruits which are consumed by birds. Those of the Viburnums—sheep-berry, withe-rod, cranberry-tree, etc.—are all patronized by grouse, woodpeckers, and the thrushes and their allies, though by no means with the zest shown for cherries and other more favored fruits. The elder-berries, on the other hand, have a more pro- nounced following. The common elder-berry in particular attracts birds in such numbers and variety that it ranks among the leading wild fruits in this connection. The red- berried elder is not so highly regarded, though it is visited by wood-peckers and a few other birds. Among the late-maturing berries are those of the dog- woods, belonging to the order Cornacew. There are several sorts of these which birds seem to hold in about equal esteem. They are taken in moderation by nearly or quite all the birds mentioned above as feeding upon fruits of this nature. The one berry in this order of which the birds are particularly fond is the sour-gum. Thrushes, woodpeckers, crows, jays, and grouse are found assembled for this and persistently abiding by it until the supply is gone. Among the heaths (Ericacee) the most prominent fruits on the avian bill of fare are the blueberries and huckleberries. The abundance and edible qualities of these berries suffice to account for their large consumption by all the fruit eaters. Birds find the seclusion of the bushes not less agreeable than the good food, just at a time when both are needed. It is not strange that so many of them desert orchard and village trees for the blueberry pastures when the trials of rearing the young are over. The black alder, of the holly family (dcinece), is another late-maturing berry eaten by woodpeckers and the thrushes 38 BIRDS IN THEIR RELATIONS TO MAN. and their allies. After the leaves have fallen the bright red color of these berries renders them very conspicuous. To us they have an abominable taste, but evidently the birds do not dislike them. In the wooded swamps where they grow one may often find robins up to the verge of winter, long after these birds have disappeared from the fields, subsisting almost wholly on these berries. Other members of the Ilex family, such as the holly and Cassenna, are also eaten. Among the miscellaneous small fruits devoured by birds must be mentioned the grapes and the berries of the Vir- A SPRAY OF BARBERRIES. ginia creeper, which are taken by woodpeckers and many other birds. The mulberry has many devotees, among them the cuckoos. Pokeweed, in spite of its poisonous properties, supplies berries for a multitude of birds. It is a notable fact that wherever a wood-lot is cleared, pokeweed—if it grows anywhere in the neighborhood—is sure to spring up in abundance from seeds dropped by birds at their roosts. Par- tridge-berries, which remain unchanged through the winter, are relished by grouse and pigeons in both spring and fall. THE VEGETABLE FOOD OF BIRDS. 39 The persistent fruit of the common barberry, which along the New England coast is thoroughly established, ministers largely to the support of the robins, flickers, bob-whites, and ruffed grouse that winter here. Persimmons, hackberries, spice- berries, cranberries, crowberries, sarsaparilla, greenbrier, In- dian turnip, and many other wild fruits are eaten by birds to a greater or less extent, but none of them compare in im- portance with those that have been mentioned. THE CULTIVATED FRUITS. Of the cultivated fruits, cherries are subject to pilferings by cedar-birds and robins to an irritating extent. Cat-birds and woodland thrushes are less troublesome, on account of their retiring habits. Strawberries, raspberries, and blackberries are similarly affected. Currants and gooseberries are on the food list of the robin and the English sparrow at least: Apples are tasted by pine and evening grosbeaks, woodpeck- ers, blue-jays, English sparrows, and ruffed grouse, but the fruit thus molested is usually of poor quality, growing in out-of-the-way places. The grosbeaks eat both seeds and pulp of the apple during their winter peregrinations. In autumn the ruffed grouse frequents the neighborhood of scrub apple-trees in the alder runs as well as in neglected fields, and for a month or so subsists largely upon apple pulp. Pears, plums, peaches, and oranges are occasionally tapped by English sparrows and woodpeckers, but none of these has yet acquired the habit of molesting such fruits to any considerable extent. On the whole, the harm done by birds to cultivated fruits is of comparatively little consequence, except in some of the special fruit-growing regions. Probably it rarely begins to offset the good done by the birds through the destruction of insects. 40 BIRDS IN THEIR RELATIONS TO MAN. BUDS AND BLOSSOMS. A few birds make a practice of eating the buds of trees and shrubs. These are mostly winter birds which otherwise could scarcely find subsistence in the North after snow falls. While snow lasts the ruffed grouse lives almost wholly upon buds, preferring those of poplar, apple, and maple trees, but occasionally sampling the tips of birch, hazel, and other twigs. Pine and evening grosbeaks are also fond of buds, apparently without much regard as to kind, for they eat the buds of a large number of trees, both evergreen and deciduous. In early spring the swelling buds of oaks, maples, and elms are relished by the rose-breasted grosbeak, purple finch, English sparrow, and the cross-bills. In the garden and orchard the buds of grape-vines, currant- bushes, peach, plum, cherry, apple, and pear trees are some- times eaten by English sparrows, purple finches, and pine grosbeaks, but it is rare that any injury from this cause is noticed. The ruffed grouse, however, is capable of inflicting real damage by a too close pruning of buds, and cases are known where apple orchards located near woods have been rendered useless by them. The blossoms of trees are of considerable indirect interest to a number of birds because they attract so many insects. Orioles and warblers are always associated with apple blos- soms in the mind of the naturalist, because he invariably finds them associated in nature. They may sometimes eat a petal or a few stamens: they certainly destroy a multitude of insects. The cedar-bird, however, has a liking for petals, and devours them greedily, and so does the purple finch. Probably other birds will be found to take parts of flowers. But the eating of petals and stamens can hardly be deemed injurious until it becomes much more common than at present. The only native birds that are given to eating leaves are the few wild species that are most nearly related to our domestic THE VEGETABLE FOOD OF BIRDs. 41 fowls. The wild turkey, all of the grouse, the geese, and many of the ducks feed freely upon them. None of these birds seem to have much preference, but take such leaves as are found convenient. The ducks, for instance, are usually limited to aquatic plants. Lel-grass is eaten by many of them, notably the scaups, the red-head, and the canvas-back. Geese are more terrestrial, and consequently they enjoy a more extensive bill of fare. The more strictly vegetivorous grouse plucks right and left, as may be inferred from the fol- lowing list of leaves taken by us from the crops of ruffed grouse: crowfoot, chickweed, clover (both white and red), strawberry, barren strawberry, everlasting, dandelion, golden- rod, sheep-laurel, sheep-sorrel, apple, and willow. Sheep- laurel, so poisonous to lambs, is eaten with impunity, though it is thought to render the flesh of the bird poisonous to man. Roots are mostly exempt from consumption by birds. The crow occasionally uncovers newly planted potatoes and feeds on them. Both Irish and sweet potatoes are relished by cranes, which are said also to devour the roots of pond-lilies. The roots and bulbs of aquatic plants are eaten by geese and vegetivorous ducks whenever they are to be had. Only the larger birds are powerful enough to get at roots or to eat them after they are exposed. The great majority are con- tent to let them fulfil their mission, and await results above ground. SAP. The sap of maples, birches, mountain-ash, and a few other trees is enjoyed by several of the wood-pecking birds. Chicka- dees may be seen, at the right seasons, tapping the smooth twigs of maples and attentively sipping the forth-coming drops. Some of the woodpeckers have the same habit. The most notorious among them are the yellow-bellied woodpeckers, or sapsuckers, which are inveterate tipplers of the sap of black and: canoe birches and mountain-ash. They also eat the tender inner bark of these and other trees. CHAPTER IV. THE ANIMAL FOOD OF BIRDS. In the later pages of this volume the fact will become apparent that a very large proportion of the food of birds consists of insects,—the little creatures that fill the air, the water, and the earth with life. Adult insects in general have a body divided into three parts, called the head, the thorax, and the abdomen, with three pairs of legs, one pair of an- tenne, and usually two pairs of wings. They are grouped together in certain natural orders, of which, from our present point of view, the following are the most important. The order Orthoptera includes the crickets, grasshoppers, cockroaches, locusts, and walking-sticks. These insects have four wings, the front pair being thick and leathery, and the hind pair thin and membranous. There are few groups of injurious insects that enter so largely into the composition of the food of birds as do the locusts, or short-horned grasshoppers, of the family Acridiide. The enormous destructive power of these insects is well known, but our indebtedness to birds in checking their oscil- lations is less generally recognized. No more convincing proof of the latter, however, could be required than Professor Samuel Aughey’s records of the food of birds in Nebraska during outbreaks of the Rocky Mountain locust,—records which show that birds of all sizes and kinds turned their at- tention to reducing the ranks of the invaders. Similar results may be seen in many portions of the United States whenever the local non-migratory species of locusts become unusually abundant. The life-history of these insects is simple: the eggs are deposited late in summer or early in autumn a little below the surface of the soil; the following spring they hatch 42 Photographed from life by Dr. BR. W. Shufeldt. THE YELLOW-BILLED CUCKOO. THE ANIMAL FOOD OF BIRDS. 43 into young, which resemble in a general way the adults. These young "hoppers feed upon grass, clover, and similar plants, increasing gradually in size and occasionally shedding their skins. In the course of about two months they acquire wings and become full grown. The Rocky Mountain locusts develop normally on the high, dry table-lands of the Rockies and occasionally migrate in vast numbers to the fertile fields of the Mississippi Valley. The red-legged locust is the most abundant of the widely dis- tributed species of this family. These insects form a large part of the food of nestling birds as well as of the adults. The family Locustide, which includes the long-horned grass- hoppers and katydids, is at once distinguished from the Acridiide by the very long an- tennee. These insects are also of much less economic impor- tance, but some species occa- sionally become seriously injurious. They are often preyed upon by birds, both in the egg and mature states, the latter fre- quently being fed to nestlings, and with some species of birds they form a comparatively important element of food. The crickets, belonging to the family Gryllide, are abundant everywhere in fields and meadows, and probably do consider- ably more damage than they are usually accused of. In the Northern States the common black species usually winters over in the condition of the egg, although a few manage to come through in a partially grown state. Their eggs are deposited in the ground by means of the long pointed ovi- positor of the female. The climbing or tree crickets of the genus (Ecanthus are perhaps the most injurious members of the family. They deposit their eggs in the canes of the rasp- STAGES OF THE ROCKY MOUNTAIN JTOCUST, (After Riley.) 44 BIRDS IN THEIR RELATIONS TO MAN. berries and in the twigs of various fruit- and shade-trees, making longitudinal slits that cause the death of the cane or twig. The adult tree-crickets feed to a considerable extent upon aphides, and so are by no means an unmixed evil. They are occasionally eaten by birds. The most destructive species of the Hemiptera, or half- winged insects, is the chinch-bug, a pest that often causes losses amounting to millions of dollars in a single State and a single season. The adult is a blackish insect, slightly less than one-fifth of an inch long, with the legs dark yellow and their tips black. The young do not differ from the adult in general form. When first hatched they are pale yellow, but they soon become red; this continues to be the prevailing color until the pupa or last nymph stage is reached; the insect is then grayish or brownish black. The eggs are small and amber-colored. These pests attack corn and small grains in enormous numbers, ' sucking out the sap and thus weakening or destroying the plants. The chinch-bug is the type of a large group of the true bugs called the Heter- optera, another typical example of which is the tarnished plant-bug, illustrated epee RES Rey herewith. There are many different Magnified. (Ayter Garman.) families in this suborder, a large propor- tion of which are protected from being eaten by birds by their disagreeable odor, which is doubtless the accompaniment of an equally disagreeable taste. The other suborder of the Hemiptera—called the Homop- tera—includes several important families of noxious insects, the members of which, fortunately, enter largely into the food of birds. The most notable of these families are those of the leaf-hoppers and the plant-lice. The leaf-hoppers of the family Jasside are very often found in the stomachs of birds. These insects are small THE ANIMAL FOOD OF BIRDS. 45 crealures with elongate-oval bodies and hind legs fitted for jumping. An idea of their appearance nay be obtained from the accompanying picture, which represents the well-known rose leaf-hopper. The adult of this species is about one-tenth of an inch long, with a yellowish-white body and white semi-transparent wing- covers. It injures the rose-leaves by suck- ing out the cell contents, giving the upper surface a white-spotted appearance. Once or more members of this family live upon a large proportion of the flowering plants, ‘both wild and cultivated, and often do serious damage. None of the true bugs are so constantly and generally injurious as the plant-lice, or Ne tals aphides, which form the family Aphidide. Magnified, The common “green fly”? of house plants is an example of this group, and nearly every cultivated crop is subject to the attack of one or more species. The normal life-history of these little creatures may be briefly outlined in this way: In the spring there hatches from an egg deposited the autumn previous a little plant-louse that sucks the sap of its food-plant for a number of days—sometimes for a fort- night—before it becomes fully grown. During this period of growth it moults, or sheds its skin, a number of times, to provide for its rapidly increasing size. This plant-louse, which developed from the egg, is often called the ‘‘stem- mother :” she is always wingless. Soon after reaching ma- turity she commences to give birth to living young, con- tinuing the process for several days. These young resemble the stem-mother in general appearance, being, of course, much smaller. Each soon begins sucking sap on her own account, and in the course of ten days .or a fortnight be- comes mature and commences to bring other living aphides into the world; the latter soon mature and give birth to a 46 BIRDS IN THEIR RELATIONS TO MAN. third generation. All of these early broods are what are called parthenogenetic females, giving birth to. living young without the presence of any males. Many of these plant-lice are provided with wings, but the majority are wingless. This process of reproduction is continued throughout the warm season, but on the ap- proach of cold weather a true sexual genera- tion is produced, the males of which may be either winged or wing- less, while the females are always wingless. By union of these two forms the true winter eges are produced: the eggs are generally deposited upon the branches of trees or other plants; they pass through the winter and in spring hatch into stem-mothers which renew the cycle of existence. Many of the smaller birds, such as the warblers, nut- hatches, kinglets, and chickadees, appear to feed largely upon aphides and their eggs. These insects are only rarely found in the stomachs of larger birds, like the robin, cat-bird, and the various thrushes. A large part of the winter food of the chickadee consists of the eggs of aphides. The moths and butterflies form the order Lepidoptera, or scaly-winged insects. Under the microscope their wings are shown to be covered with minute scales which overlap one another. The adults are very different from the larve, and in consequence these insects are said to undergo complete transformations. The three later stages of the common cat- erpillar which infests cabbages—the cabbage-worm—are rep- resented in the picture herewith. The female butterflies deposit their pale greenish-yellow eggs, singly or in clusters, on the leaves; the larvee soon hatch and feed upon the sur- AN APHID, MAGNIFIED, AND ITS EGGS ABOUT BUDs.

When fully grown each spins a slight silken loop on the cabbage-leaf or some near-by shelter, generally on the lower surface, and changes to a pupa or chrysalis. In a short time it emerges as a butterfly. A large proportion of the caterpillars of the Lepidoptera are eagerly devoured by birds, forming an important element of the food of many species. Mention can be made here of only a few of the more important families. There is a large family of small moths called Yortricida, the MINE OF APPLE LEAF-MINER. larve of which are com- monly known as ‘ leaf- rollers.” The normal habit of these little cater- pillars is to feed upon the surfaces of leaves which they roll into a protective covering ; sometimes they live singly and sometimes a number live together in a common nest. Insects - of this family attack the leaves of nearly all our fruit and ornamental trees, although, fortunately, they generally do little damage. Some species are not con- tent with the foliage, but feed upon the fruit; the - too well-known codling- moth, or apple-worm, is an example of this group. The larvee, pup, and moths of the leaf-roller family are all eagerly devoured by birds, but these insects are greatly pro- tected by their habits and colors, so that probably birds do THE ANIMAL FOOD OF BIRDS. 49 nol affect them so seriously as they do the insects of many other groups. a The leaf-miners differ from the leaf-rollers in that the larvee live within the tissues of the leaf, as in the case of the apple leaf-miner illustrated on the opposite page. The families of looping or measuring caterpillars—Geome- tride and its allies—are of special interest from an ornitho- logical point of view because they contain many species which in their larval state so closely resemble small twigs that they easily escape the notice of birds. A few species, like the canker-worm, are of much economic importance on account of their injuries to the foliage of fruit and shade trees. Such species, as a rule, are less perfectly protected in their resem- blance to twigs than others, and when abundant are freely eaten by birds. The moths of these families have slender bodies and comparatively large wings, although sometimes the females are wingless. The great family of night-flying or owlet moths—called by entomologists Noctuide— includes a large number of the most injurious -insects. The boll-worm of cotton, the army-worm, and the various cut-woris, all be- long here. The cut-worms are rather thick, naked worms which hatch from : : : THE ARMY-WORM. eggs laid by medium-sized (From New York Experiment Station.) moths. Most of them feed upon grass or clover when young, becoming half grown before winter. They hibernate beneath some shelter and in spring come forth in search of food, attacking a variety of young plants by biting off the stems and feeding on the leaves. They become full grown during spring or early summer, pupate beneath the soil surface, and a fortnight or more later emerge as moths. 4 50 BIRDS IN THEIR RELATIONS TO MAN. Fortunately, cut-worms and their allies form a large pro- portion of the food of many birds. They are especially used by the old birds for feeding the nestlings. The families of silk-spinning moths and their allies-—for- merly included under the Bombycide, but now subdivided into many groups—include a number of the most injurious insects affecting fruit and shade trees. The larve of this group are hairy caterpillars which feed upon leaves, and when full grown spin silken cocoons for protection in the pupa state. The tent caterpillar of the apple and wild cherry, the fall web- worn, the tussock-caterpillar, and many similar insects be- long here. One of the most notably destructive members of the group is the gypsy moth, recently so prominent before the public 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 larvee feed upon the foliage of nearly every kind of tree and shrub. Comparatively 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 skins thus swallowed; probably our species have a similar habit. The larger bombycid caterpillars—like those of the cecropia and polyphemus moths—are eaten by some of the hawks. TENT CATERPILLAR'S NEST RAIDED BY BIRDS. THE ANIMAL FOOD OF BIRDS. 51 The highest group of the Lepidoplera includes the familiar butterflies. In their earlier stages they are caterpillars, many of which form a portion of the diet of birds. Many of the larger butterfly larvae seem to be protected from the attacks of birds by a disagreeable taste or smell. The caterpillars of the beautiful papilios have a peculiar pair of yellow or orange-colored Y-shaped organs concealed just back of the head. When the larva is irritated these are thrust out; they emit a very disagreeable odor and are supposed A CRANE-FLY, to be useful as a means of protection from birds and other animals. The order of two-winged flies—Diptera—contains com- paratively 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 destructor), often so serious an enemy to wheat. The adult is a small gnat-like creature whose eggs are de- posiled on the blades of growing wheat, the resulting larvee absorbing the 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 the family Tipulide are often found in birds’ stomachs. The adults of these insects appear in spring, often in great numbers, 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. When full grown they are about an inch long and of a grayish-black color. They now change to pup, to emerge as adult flies a fortnight later. The larvie 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 which 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 commonly 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 (Cicindelide), the members of which devour many other insects, being pre- daceous in both the larval and adult states. These beetles are often brightly colored and marked 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 Carabide form an im- THE ANIMAL FOOD OF BIRDS. 53 portant element in the food of many birds, especially the thrushes and their allies. These beetles vary much in their habits: some of them—especially those belonging to the genus Harpalus and others related to it—feed largely upon vegetation of various kinds, while others—particularly those of the genus Calosoma and its allies—are strictly carnivorous, being excellent examples of predaceous beetles. The vege- tivorous group enter most largely into the food of birds. Many of the carnivo- rous ones are so protected by offensive taste or odor that they are not eaten at all. Some of the larger ground-beetles are called ‘caterpillar hunters,” be- cause they prey upon cutworms, canker- worms, and various other caterpillars. The lady-beetles, or ‘lady-birds,” of the family Coccinellide, are extremely useful as destroyers of plant-lice and other insects. Fortunately, they appear to be distasteful to birds, as they are very seldom eaten by them. The hard, cylindrical, yellow worins frequently found in the soil of meadows and grain fields and commonly called eee eet og ‘ Magnified. (From Insect Life.) ‘“wire-worms” are the larvee of the click or snapping beetles of the family Elateride. These larve feed upon the roots of plants and sometimes do serious dam- age to young corn and wheat. They are extremely difficult to combat by artificial means; hence we are glad to know that both the larve and adults are fed upon to a considerable extent by various birds. In the great family of leaf-beetles—the Chrysomelide— which is said to include more than ten thousand described species, we find many insects which are destructive to culti- vated crops. The most notorious American member of the 54 BIRDS IN THEIR RELATIONS TO MAN. family is the Colorado potato-beetle, but there are many others, such as the corn-root worm, the various flea-beetles, the striped cucumber-beetle, and the asparagus-beetle, which are almost equally injurious. The larve of this group vary much 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 larvee are protected in some way from the attacks of birds, which apparently devour many more of the adult bee- tles than of the larve. The common May-beetle, or ‘‘June- bug,” belongs to a family—Scarabwidee —which contains many other well- known depredators. This insect is developed from the white grub, or “‘erub-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, brown 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 larvee feed upon roots. When fully grown they change to pup 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 Cureulionide and certain related families grouped together in a suborder called Rhyncophora. 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 larve of these insects are usually footless grubs and feed upon a variety of materials. The adult beetles have a habit when disturbed of dropping to the ground, drawing the legs against the body, CLICK-BEETLE AND LARVA. (After Bruner.) bf THE ANIMAL 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. This means of escaping observation doubtless saves some of them from the attacks of birds, but nevertheless a considerable number are eaten by our feath- ered allies. The salient features in the life-history of the family may be gathered from that of the plum-curculio. The adult beetles deposit eggs in the young plums and the result- ing grubs feed upon the pulp of the fruit. They become full 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 jaws of these insects are fitted for biting and the remaining mouth parts for sucking. The transformations are complete, and the 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 species. Few families of insects enter more largely into the food of birds than that of the ants (Formicide). 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 beneficial 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 group of parasitic insects is that comprising the ichneumon-flies of the families Braconide and Ichnewmonide of modern entomologists. These little creatures vary greatly in life-habits, but a large proportion of them are primary parasites of injurious insects. The 56 BIRDS IN THEIR RELATIONS TO MAN. adults are four-winged flies with slender bodies and long antenne, and the larve 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 the body of the larva selected SPHINX LARVA WITH cocoons or parasite; as the victim: they soon sonatas aterm. hatch into grubs that de- velop at the expense of the tissues of the host. Some of the ichneumon-fly larvee are internal parasites, living beneath the caterpillar’s skin, while others attach themselves externally. In either case the host insect is doomed: it may be killed long before it gets its full larval growth, or it may be allowed to complete that growth and spin a cocoon, but sooner or later the parasites—like the fox in the fable—will gnaw away its vitals. When the ichneu- mon larvee become fully grown, they generally spin slight silken cocoons, within which they change to pupae, to emerge later as adult flies. There is a group of ichneumon-flies, commonly called Microgasters, which spin their cocoons on the back and sides of the larvee of butterflies and moths, giving the host a most singular appearance. A specimen of a common sphinx larva bearing these cocoons is represented above. Ichneumon-flies are eaten lo a considerable extent by many birds, especially the flycatchers. The fact that a bird may eat a certain number 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 Chapter VI. Besides the insects proper there are many animals that are eaten by birds. The spiders are the most 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 which feed largely upon’ insects. They are found in all sorts of places and during 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 different parts of / A HARVEST-SPIDER, the United States, form a distinctive family,—Phalangiide,— distinguished by having the three divisions of the body—head, thorax, and abdomen—closely united, and four pairs of very long legs. A common 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 thrushes. Some Myriapods, of which the common [ulus 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 by hawks, owls, and other raptorial birds, as well 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. Photographed from life by Dr. R. W. Shufeldt. AMERICAN LONG-EARED OWL, CHAPTER V. THE AMOUNT OF FOOD CONSUMED BY BIRDS. Birps 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, oflen two or more broods in a summer ; and, in short, perform for their size a prodigious amount of work. Beeause- 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 whole mass of ornithological literature—which latterly has increased to very respectable proportions—there is a striking paucity in this line. Itis 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 vis 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 IN THEIR RELATIONS TO MAN. Sixteen canaries mentioned by Dr. Stanley! ale 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- low 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 American Naturalist 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-vite 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 (Bla- rina), one common mouse (Jus), 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 March 26, twenty-eight days, evidence of one crawfish, five birds, two shrews, one jumping mouse (Zapus), and one hundred and five field-mice. Pellets believed to have come from the same owls, found under trees within a radius of an eighth of a mile, contained remains of five birds (Regulus, Junco, Certhia), 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 conseeutive days, December 25 to January 15, Dr. Montgomery counted four owls in the arbor-vite tree 1 History of Birds, p. 225. 2 Id., p. 1438. 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 that 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 fur a food experiment. He was put inlo 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 was fairly tame and ate freely while being watched. We secured a quantity of small fish (Fundulus), which were abundant in the brackish creeks, and offered him some on the fifth day. He ate thirty grammes of thei that day in addition to grain and the usual supply of earthworms. On the 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 right 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 (avoirdupois),—making his daily consumption 4.83 ounces, more than a quarter of his own weight. It would take over four hundred grasshoppers at maturity to weigh as much as did his daily ration of fish. 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 between 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 cat 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 larvee, 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 (4éschna heros), just from their pupa-skins, were brought in. Beetles, moths, larvee, 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, per 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. 21d., p. 27. *Id., p. 69. ‘Id., p. 78. THE AMOUNT OF FOOD CONSUMED BY BIRDS. 63 per day, the total amount of excreta passed by each bird is 7.5 drams. Adding the daily gain to the daily excretion gives 8.6 drams, the daily food during the eleven days. After the eleventh day more nutrition goes inlo 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 97" i tlace oo Tetaceee 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 inorning 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 cesophagus into the proventriculus, for the bird stretched his neck as if in distress after they had been swallowed awhile. 64 BIRDS IN THEIR RELATIONS TO- MAN. Mr. Daniel E. Owen has recorded! some interesting obser- vations on the food of a young hermit thrush recently from the nest. It ate regularly half its weight 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 white 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 trustworthy, 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. Three robins about ten days old observed by us were fed in two hours one bird-cherry (P. pennsylvanica), one large cricket (Gryllus), one smooth caterpillar an inch and a half long, one moth (Noctwid), one harvest-man (Phalangiide), one tumble-bug (Copris), two earthworms (Lumbricus), two carabid beetles, twenty-nine grasshoppers (cridiide), and eight small creatures thought to be spiders but which could not be made out with certainty. These forty-seven items were brought at thirty visits between 4.04 and 6.03 a.m. During the middle of the day the old birds came less often. Be- tween 10 and 10.30 there were four visits, from 1.25 to 1.51 1The Auk, vol. xiv. pp. 1-8. 2Td., 1890, vol. vii. p. 290. THE AMOUNT OF FOOD CONSUMED BY BIRDS. 65 there were six, and from 2 to 3 there were six. Ten visits . per hour was the average the day through. Over three-fourths of the food brought consisted of adult grasshoppers, the great Carolina locust being often among them. Half of the time two were 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-five 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 every 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 children 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. ‘These grubs averaged thirty to the ounce, so the young robin ate one hundred and sixty-five cutworms in one 1 Birds of Ontario, p. 22. 5 66 BIRDS IN 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 pumilus, 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 ealers. Eight days is a short time for the accomplishment of so great a change. 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 fledglings between 5.13 and 5.83 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 Aeri- diide and others to the family Locustide. 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 (Noctuide), nine spiders, nine grasshoppers, fifteen May-flies, and thirty-four caterpillars. On the following day similar observations were 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 (Cingilia). 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 chipping-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 other caterpillars being often observed.’ These observations are certainly sufficient to establish the fact that birds as a class consume an enormous amount of food. 1 Yearbook, U.

Ir 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 such 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. Asa 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 summary. * Bulletin of the Illinois State Laboratory of Nattiral History, vol. i., No. 6. 68 THE CAT-BIRD. BIRDS AS REGULATORS OF OUTBREAKS. 69 Nine robins had eaten only animal food, of which canker- worms formed twenty, cutworms twenty-eight, and vine- chafers fourteen per cent., making a total of sixty-two per APPLE-LEAVES ATTACKED BY CANKER-WORMS. cent. for these three groups of insects. Eleven per cent. of the remainder consisted of click-beetles (Elateride). 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 “none of them had eaten 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 BIRDS IN THEIR RELATIONS TO MAN. ealen only canker-worms and beetles, the former making 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 ofseveral house-wrens consisted of canker- worms. Passing now to the warblers (Mniotiltide), we come to many spe- cies feeding largely on canker-worms. Four- fifths of the food of a single Tennessee war- bler consisted of these insects. Two-thirds of that of five sum- mer yellow-birds was canker-worms, and the 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 BLUEBIRD. 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, which 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 flying insects. Two specimens of Traill’s flycatcher had eaten twenty-five per cent. of canker-worms, and a single yellow-bellied fly- catcher had eaten an equal percentage of vine-chafers 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-worms, 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 was 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, were 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 cannot be mistaken. Whatever power the birds of this vicinity possessed as checks BIRDS AS REGULATORS OF OUTBREAKS. 73 upon destructive irruptions of insect life was being 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, perhaps incipient, but evident enough to express themselves clearly in the changed food ratios of the birds. (2) The comparisons made show plainly that the reflex effect of this concentration on two or three unusually nu- merous insects was so widely distributed over the ordinary elements of their food that no especial chance was given for the 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 compensated 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 other 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 that 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 thatinsect. Fortunately, the results of these studies have been preserved by the United States Entomological Commission.1 Between 1865 and 1877 Pro- 1 First Report, Appendix II. 74 BIRDS IN THEIR RELATIONS TO MAN. fessor Aughey made a careful investigation of this subject, both by out-door observations of living birds and by in-door examinations of stomach contents. His tabulated results show conclusively that birds of all kinds were doing their best to reduce the numbers of the locusts. g a {a|/&{j2z;e]a/4 jaa Hymenoptera . . 16 1 O | 17 |) 126 8] 0 | 184 Lepidoptera ........ 0 6 0 6 0|) 16] O|} 16 Diptera : : x8 , 1 0 0 1 1 0 0 1 Coleoptera . .| 28 | 16 8 | 47 85 | 47 | 32) 174 Hemiptera ...... 1 1 1 3 1 1] 1 3 Orthoptera ...... 0} 17 O| 17 0| 150; 0 | 150 Neuroptera 0 0 1 1 0 0; 18) 18 Total. . es 41 | 41 | 10 | 92 || 218 | 282) 51 | 496 - A number of observers have reported that the crow kills and eats field-mice and pocket gophers. Others claim 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 summarized 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 distribution of seeds of poison-ivy, poison-sumach, and perhaps other noxious plants. (6) They do much harm by the destruction of bene- ficial insects. On the other hand, (1) They do much good by the destruction of injurious insects. (2) They are largely THE ORIOLES, BLACKBIRDS, CROWS, AND JAYS. 171 beneficial through their destruction of mice and other rodents. (8) They are valuable occasionally as scavengers.” The Magpie, ranging from Arizona to Alaska and from the Rocky Mountains to the coast, except a part of California in which it is replaced by the yellow-billed variety known as Nuttall’s magpie, although of handsome appearance, has some traits that are utterly disreputable and scarcely one that may be called valuable. He is a thief, stealing the hunter’s game, the traveller's supplies, even 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 Brvue-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 farmstead. These birds are seen to best advantage among the nut trees in autumn. Then is the time of their harvest. From tree to tree they go in troops, calling in glee, swishing the branches, rattling down nuts, forcing an opening by well-directed blows of their powerful bills through hard shells, or busily engaged in hoarding sup- plies in crevices for use in the coming season of want. Hearty, energetic, versatile, the jay at this season is worth watching. As to food, he is essentially a vegetarian by preference. Nothing suits his taste quite so well as nuts,—acorns, chest- nuts, beechnuts, and similar kinds, having rather thin shells. Sometimes a flock will develop a taste for corn, and do more 172 BIRDS IN THEIR RELATIONS TO MAN. or less damage as it stands in the field, but this 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 quite 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. (After Biological Survey.) 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 Agriculture at Washington, showed that practically three- fourths of the 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 séventy-one stomachs and amounted to about eighteen per cent. for the year. The stomachs taken in autumn showed conclusively that 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 Carabide and Scarabeide. Grasshoppers and caterpillars are both eaten quite extensively. Walnut caterpillars (Datana) are sometimes destroyed in great numbers. In this analysis only two stomachs contained traces of ege-shells of small birds, and only one, remains of young. In a few stomachs were 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 GRACKLE. CHAPTER XV. THE FLYCATCHERS, HUMMING-BIRDS, SWIFTS, AND NIGHT- HAWKS. THE FLYCATCHERS. To the naturalist who wanders much afield the Puese, 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 the sight of it evokes in the mind of every one brought up in the country tender memo- ries of early associations. Nearly all of its food consists of insects, most of which are captured in the air. Perched upon an ex- posed twig or a dead mullein-stalk, the bird scans with 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 pheebe waits patiently for another morsel. Thus it spends its days. A careful examination of the contents of many phoebe stomachs by experts at Washington “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 PHGBE. THE FLYCATCHERS. 175 insects are chiefly of species injurious to man’s interests, so that these feathered friends are of great utility in reducing the hordes of noxious pests. The nest of the phoebe is built by preference upon the timbers of a bridge, with 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 with insects and their allies, including chiefly moths, grasshoppers, ants, spiders, and similar creatures. The phebe 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 Kinepirp is noted for its pugnacious antipathy to hawks and crows, and is esteemed by agriculturists for this quality which makes it a veritable knight of the farm. It 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 have made the claim against the kingbird that it is destructive to bees, but evidence furnished by dissections tends to prove that this damage is really of slight conse- 176 BIRDS 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 two 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- pers and is regarded as a pest by pepper- planters. This spicy diet gives its flesh a pungent 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 Great Crestep, the Least, and the Woop Pewre—appear to have feeding habits very similar to the phoebe and the kingbird, although, of course, woodland species find insects of quite different sorts from those in cultivated spaces. THE KINGBIRD. (After Biological Survey.) THE HUMMING-BIRD AND THE CHIMNEY-SWIFT. 177 THE HUMMING-BIRD. Only one species—the-Rusyruroat—of the beautiful family of humming-birds (Zrochilide) 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 proportion of the two elements prob- ably varies 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 Hampshire, ‘the humming-birds, at ‘ orchards’ where 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 wagging 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 CHIMNEY-SWIFT. The swifts (Cypselide) are represented in eastern North America by but one species, the abundant Cuimney-Swirt, or CHIMNEY-SwaLLow, a bird of marvellous powers of flight, with small and slender body, long, pointed wings, and not a grain of superfluous flesh: an aerial thoroughbred, built for cleaving the air in chase of the insect quarry that forms its 1 Science, vol. xx. p. 318. 12 178 BIRDS IN THEIR RELATIONS TO MAN. food. Before the discovery of America, when the rude smoke-holes that served as chimneys for the wigwams and long-houses of Choctaw or of Iroquois extended no invitation for these birds to nest in them, hollow trees more or less open at the top took the place of the modern chimney. In thinly settled districts of the West such trees are still used for the purpose. The nest is built of little twigs broken off from the trees while the bird is in full flight, which are stuck together and to the sides of the chimney or tree by saliva. The same nest is sometimes used for two or three seasons. A large number of birds often choose the same tree or chimney for breeding and roosting purposes. The chimney-swifts are abroad at all hours of the day and night, but fly most freely from earliest dawn till soon after sunrise, and again before sunset till after dark. Doubtless at such times the insects on which they feed are most abundant in the air. Their food is varied, probably consisting of almost all the flying insects with which they come in contact. Three specimens studied by Professor 5. A. Forbes had eaten ants, moths, ground-beetles, rove-beetles, plant-beetles, flies, bugs, and spiders. The young are fed largely upon grasshoppers when these are abundant, and at other times on various kinds of insects. There has long been prevalent a popular idea that these birds winter in a lethargic state in chimneys and hollow trees, but all well-informed ornithologists declare this statement to be preposterous. According to Stejneger the chimney-swifts are found in Mexico in winter. It would be very strange if a bird of such powers of flight as this should choose to sleep away the cold season, instead of basking in the sunshine of the South to be reached in so short a time. THE NIGHTHAWK AND THE WHIPPOORWILL. _ The strange family of goatsuckers, or night-jars (Caprimul- gide), is represented in the United States by eleven species THE NIGHTHAWK AND THE WHIPPOORWILL. 179 and subspecies, only two of which, however, are commonly found over the largest portion of our country, the others occurring in the Southern or Southwestern States. Every one is familiar with the plaintive cry of the Wuippoorwit, one of the commonest members of this group. It is a noc- turnal bird and secludes itself by day in the darkest recesses of the woods. In such places also the young are reared, the two creamy white, brown-blotched eggs being deposited on the ground or on a log or stump, with no attempt at a nest. By night it flies rapidly through the air, catching in its capa- cious mouth flying insects of many kinds. The few stomachs that have been examined show that it feeds largely on night- flying moths, sometimes taking those having a wing expanse of two inches. Click-beetles and other beetles are also often devoured. Four-fifths of the food of one specimen consisted of injurious grasshoppers. One Ontario specimen had _ its stomach filled with “the large female wingless ants, which could only have been obtained upon the ground, and in all probability in the daytime.””! The NicHTHawk, or Buii-Bat, is seen much oftener than the whippoorwill, on account of its greater abundance and its habit of flying about everywhere, especially on dark days and towards dusk. Small flocks of them may frequently be seen cleaving the air in all directions, coming close to men and houses in their rapid evolutions. Its two eggs are laid on the ground, generally in secluded situations, although of late it often uses the flat roofs of Boston houses as nesting-places. It is a great insect eater, its food consisting of May-flies, dragon-tlies, beetles of many kinds, ‘‘ water boatmen,” scor- pion-flies, bugs of various sorts, and many grasshoppers. From seven Nebraska specimens Professor Aughey took three hundred and forty-eight Rocky Mountain locusts, an average of forty-nine to each bird. An Arkansas specimen examined ' Nash, Birds of Ontario, p. 29. 180 BIRDS IN THEIR RELATIONS TO MAN. by F. L. Harvey contained more than six hundred insects,— gnats, beetles, flies, ants, and grasshoppers. Professor Her- rick has found that the young are fed largely on firefly beetles. The nighthawk frequently suffers from the thoughtless cruelty of amateur gunners who shoot at them as they fly in the air. This is unworthy ‘sport’ for boy or man. These birds are not only very useful as insect destroyers, but, as Mr. E. B. Williamson has written, they are also ‘“‘ handsome birds, adding much to the twilight beauty of a summer evening as the scattered flocks pass with easy and graceful flight over fields and woodland.” THE LUNA MOTH.

In a general way each family of birds is set apart to perform certain special functions in the economy of nature. To the woodpeckers has been assigned the task of keeping in check the borers concealed beneath the bark of trees, and, inciden- tally, of devouring any other insects which may be scattered about the trunk and branches. With the single exception of the yellow-bellied species, all our woodpeckers appear to be eminently beneficial. The peculiarities of their structure eminently fit them for their special work: the feet generally have two toes in front and two behind, all armed with sharp claws, enabling the birds to hop up trees with ease; the tail feathers are short, stiff, and rigid, serving as a support when the bird gives hammer-like strokes with its chisel-shaped beak ; and the tongue, in all except the yellow-bellied species, is extensile and generally barbed on the edges near the tip, so that it can be thrust into burrows to impale the occupants. There are about thirty forms of the Picide—the woodpecker family—recognized in North America. Most of them remain throughout the year in the localities in which they occur. The Ivory-BitLeD Wooppecker is the monarch of the family. It is a large, handsome, powerfully built bird, twenty inches long, with a wing expanse of thirty inches. Occurring only in the Southern States, it there is found in the deepest woods and swamps, far away from human habitations. The Pieatep WooppeckeER is a species nearly as large as the one just men- tioned and has similar habits, though it is more generally distributed over the United States. Both are rare birds, inhabiting solitary forests; on account of their shyness, they 181 182 BIRDS IN THEIR RELATIONS TO MAN. are not likely ever to have much economic importance in civilized communities. Analyses of the stomach contents of the pileated species have shown that it feeds largely on ants, beetles, and other insects which it finds in dead trees and logs, the beetle larvee that bore into the trunks of trees being especially taken. It also feeds upon the seeds and berries of many sorts of wild fruits, such as the sour-gum, flowering dogwood, black haw, hackberry, persimmon, wild grapes, Virginia creeper, greenbrier, sumac, and poison-ivy. In the stomachs analyzed by the Biological Survey the animal and vegetable matter was about equally divided. THE HAIRY WOODPECKER, (After Biological Survey.) Either the typical form or that of some variety of the Hairy WooprPEckER occurs commonly in most parts of North America. This is a particularly useful bird, visiting freely the kings of the forest, as well as the fruit-trees of the orchard and the shade and ornamental trees of the home grounds, the park, or the public thoroughfare. It nests in holes in THE WOODPECKERS, KINGFISHERS, AND CUCKOOS. 183 trees, usually in the forest, and rears from four to six young. No birds search more persistently for the wood-boring grubs living beneath the bark of trees, many of which—like the flat-headed borer—are the most vexatious enemies of the fruit-grower. During their meanderings over the trunk and larger limbs they often startle moths and other nocturnal insects, which they devour whenever opportunity offers, and they also penetrate the disguise of many geometric caterpillars and cut short their deceptive careers. A good idea of the gen- eral diet of the species may be obtained from Professor King’s statement that of twenty-one specimens examined, ‘eleven had eaten fifty-two wood-boring larve ; five, thirteen geometric caterpillars ; ten, one hundred and five ants; six, ten beetles ; two, two cockroaches; two, nine egg-cases of cockroaches; two, two moths; one, a small snail; one, green corn; one, a wild cherry; and one, red elder-berries.”” More than two- thirds of the food of eighty-two specimens studied by the Department of Agriculture was animal matter, chiefly insects. In the presence of an unusual abundance of grasshoppers the hairy woodpeckers feed freely on them; four Nebraska specimens had eaten one hundred and fifty-seven of these insects. They also do good service in penetrating the cocoons of the cecropia emperor moth, the larve of which devour the foliage of fruit- and shade-trees. A number of observers have reported that these birds push their beaks through the tough cocoons until the pup inside are reached, the juices of the latter being sucked away. They have also been credited with having in 1880 ‘cleaned e]m-trees in Cleveland, Ohio, of the cocoons of the tussock-moth.” Concerning the beneficent habits of the hairy woodpecker, Dr. P. R. Hoy, a well-known naturalist, wrote many years ago: ‘Cheerful and industrious, he is always on the lookout for those worms that burrow in the substance of the wood or under the bark of trees. He is an expert at auscultation and percussion, and he is not indebted to Laennec for the art 184 BIRDS IN THEIR RELATIONS TO MAN. either. As he explores suspicious localities with gentle taps, he quickly detects the evidences of unsoundness, and is not slow to learn the cause. Worms is his hobby: soon he chips an opening, and with his long, slender tongue, armed with a barbed lance-point,—a capital tool,—he soon extracts the cause of the evil. While engaged in ‘ worming’ he continues to utter his cheerful Plick, plick! in a major key, as if con- scious that he is engaged in a good cause and not ashamed X Tyas THE CECROPIA MOTH AND ITS COCOON (REDUCED). to own it. You can always tell where he is. A few ears of corn is about all the pay he takes for his valuable work. Protect him; he is our friend.” In habits, manner, and dress the Downy Wooprecker seems but a miniature copy of its hairy cousin. It more com- monly frequents orchards and is often called the ‘ sapsucker,”’ but this is a misnomer, as that name should be confined to the yellow-bellied species. Although it bores holes in the THE WOODPECKERS, KINGFISHERS, AND CUCKOOS. 185 bark of apple-trees, it does not revisit them to suck the sap, according to the habit of the Jast-named bird; and the holes seem usually not to injure the tree. Seventeen Wisconsin 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 the 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 larvee 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 injury that can be charged to the account of this bird is that of spreading the seeds of poison-ivy, the berries of whichit 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 Fucker, 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, especially that of its bill, is modified 186 BIRDS IN THEIR RELATIONS TO MAN. to suit its peculiar habits. The ordinary woodpecker’s bill is shaped like a chisel at the tip, but that of a flicker is like a pickaxe. 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 FLICKER, 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 (Hemiptera), grasshoppers and crickets (Orthoptera), caterpillars (Lepidoptera), May-flies (Ephemerida), and white ants (Jsoptera). In 1860 a writer in the Southern Planter stated that flickers were the only birds he had ever seen pulling out worms from the roots of peach- trees,—referring evidently to the destructive peach-tree borer. The Rep-HEapED WoopreckerR is another species that, like THE WOODPECKERS, KINGFISHERS, AND CUCKOOS. 187 the flicker, has got above hard work. 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 has been THE RED-HEADED WOODPECKER. (After Biological Survey.) 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 animal 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, which, being carnivorous, are more or less useful. There are other com- 188 BIRDS IN THEIR RELATIONS TO MAN. plaints against this woodpecker besides that of killing useful beetles. Itsometimes 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. Even though it were proved that its food habits were against it, a SPINES ON ROOF OF TONGUE. Magnified. (After Lucas.) TONGUE OF RED-HEADED WOODPECKER. Magnified. (After Lucas.) bird of its rare beauty is worth seeing now and then, though we may have to pay for the pleasure. One of the most notable illustrations of the value of wood- peckers has been brought 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, AND CUCKOOS. 189 done by the spruce-destroying bark-beetle (Dendroctonus piceaperda), but that its work was being largely checked by woodpeckers, probably chiefly the Arctic THrer-rorp Woop- .PECKER and the Banpep Turee-rozp Wooppecker, as_ these species come from the far North in winter and live in northern New England in numbers. Dr. Hopkins writes: ‘“ Woodpeckers are the most 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 this 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 il 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. The result is that they are eaten to a large extent and so are prevented from killing the bark-beetles. The YELLOW-BELLIED WooppeckeER, or true Sapsucker, either in the typical or a varietal form, occurs throughout the United States. Although seldom an abundant species, it is rather common within its range. The structure of its tongue differs 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 larve. Consequently these pests are seldom found in its food. Its usual diet appears to consist of insects and berries of various 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 yellow-bellied woodpecker 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. gee Two or more series, one above the other, are usu- sarsucker. ally made in the trunk of the chosen tree. The sap eee 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 summers we have repeatedly seen these birds thus visiting the hundreds of punctures they had made in a row of English white birches along the border of Dart- mouth College park. The woodpeckers were by no means the only visitors attracted by the flowing sap: humming-birds, hornets, wasps, flies, and ants were there in abundance. The two first named were not on good terms, for whenever a ruby- throat would appear, one or more of the great white-faced THE WOODPECKERS, KINGFISHERS, AND CUCKOOS. 191 hornets would attempt, often successfully, to chase it away. But they did not interfere with the proprietors of the saccha- rine establishment. These sapsuckers seem to have surprisingly little choice in the trees selected to supply their food; besides the English white birch, they puncture the common birch, sugar-maple, pignut-hickory, pine, apple, white beech, and probably many other trees. Mr. A. W. Butler, the well-known Indiana or- nithologist, writes concerning this species: ‘‘ They do great damage in spring to fruit- and shade-trees, especially the sugar- maple. They perforate the bark with holes arranged in bands on spirals about the trunk of the tree or larger limbs, from which the sap sometimes flows in streams. I have counted six of these birds on a dozen sugar-maples in front of one lot in my own town. In winter they are especially severe on coniferous trees. Norway pines in my yard have been girdled until they became puny, sickly trees and were cut down.” Mr. Butler further reports that a friend, spending a day in the woods, * was attracted by the actions of a yellow-beliied woodpecker which had tapped a young tree near its top. It would sip the sap and then wait for it to collect and feed again. This was continued for several hours. The observer watched until five in the afternoon and left the woodpecker just where he first saw it. It had not moved more than a yard from the hole in the entire seven hours.” The young of this species seem to be fed with both sap and insects. There is no doubt that this species is undeserving of en- couragement, and when it appears to be injuring valuable trees it should be shot. The fruit-grower, however, should be sure that the birds in his orchard are not of the other species, which are highly beneficial and deserving of protection. THE KINGFISHER. The northern United States have but one representative of the interesting family of kingfishers (Alcedinidw). This is 192 BIRDS IN THEIR RELATIONS TO MAN. the well-known and widely distributed Betrep KinerisHer. «Amidst the roar of the cataract or over the foam of a torrent, he sits perched upon an overhanging bough, glancing his piercing eye in every direction below for his scaly prey, which with a sudden circular plunge he sweeps from its native element and swallows in an instant. His voice, not unlike the twirling of a watchman’s rattle, is naturally loud, harsh, and sudden, but is softened by the sound of the brawl- ing streams among which he generally rambles. He courses along the windings of the. brook or river at a small height above the surface, sometimes suspending himself by the rapid action of his wings, like certain species of hawks, ready to pounce on the prey below; now and then settling on an old dead limb to reconnoitre. Mill-ponds are particularly visited by this feathered fisher; and the sound of his pipe is as well known to the miller as the rattling of his own hopper.” So wrote Alexander Wilson many years ago; the same picture might be drawn to-day. The kingfisher goes south late in autumn, winters in Florida and other Southern States, and returns north early in spring. Many reside at the South throughout the year. The nest is made in a horizontal burrow, five or six feet long, excavated by the birds in river or other banks. The food consists principally of fish, but occasionally mice, frogs, or grasshoppers are captured. The young are fed chiefly upon fish, but are also given various sorts of aquatic insects. The kingfisher is a handsome bird, whose presence adds much to the enjoyment of excursions—by boat or on shore—along the margins of streams and lakes, although in trout-streams it is sometimes troublesome from the point of view of the fisherman. THE CUCKOOS. With a large proportion of the general public the word “cuckoo” brings to mind a bird which has the habit of placing its eggs in the nests of other birds, the resulting young ousting THE WOODPECKERS, KINGFISHERS, AND CUCKOOS. 193 the rightful occupanls from the nest. This picture is due to the influence of the European cuckoo upon our literature, and it by no means portrays the domestic habits of the American species, of which we have two, the YELLow-BILLED and the Buack-siLuED, the latter having the more northerly range. Both of these cuckoos are shy and secluded in habits, oc- curring mostly in woods and underbrush along streams, but often visiting orchards and groves. They now appear to be more worthy, since their food habits have been investigated, than they were formerly held. It is a well-known fact that the common birds of the orchard, par- ticularly the robin, expostulate loudly, and frequently show fight, when a cuckoo comes on the scene. From this it might be inferred that the cuckooisanenemy. Some of the older writers on ornithol- ogy ascribe to it the habit of invading birds’ nests. If such a habit exists, it is an exception, and not arule. Both species feed upon practically the same matter. Fruit is seldom eaten. Of one hundred and fifty-five stomachs of cuckoos taken between May and October, inclu- sive, by the Biological Survey, only one contained berries. Nearly half of the food consisted of different kinds of cater- pillars, mainly hairy ones. During May and June, when tent caterpillars (Clisiocampa americana) are stripping orchards of everything green and leaving on the bare branches their unsightly nests, they form 13 YELLOW-BILLED CUCKOO. (After Biological Survey.) 194 BIRDS IN THEIR RELATIONS TO MAN. nearly half of the cuckoos’ fare. These birds are unique in having a taste for insects that other birds reject. Most birds are ready to devour a smooth caterpillar that comes in their way, but they leave the hairy varieties severely alone. The cuckoos, however, make a specialty of devouring such unpal- atable creatures: even stink-bugs and the poisonous spiny larve of the Io moth are freely taken. About six per cent. of the food for the year consists of beetles, among which are a few potato-beetles. No preference for any particular sort of beetle is apparent: probably any beetles found crawling over branches of trees would be eaten. Investigation has shown scarcely more bugs (Hemiptera) than beetles, probably for the same reason,—both live principally on the ground,—those that were found being largely cicadas, which dwell almost wholly in trees. Grasshoppers, katydids, and tree-crickets are eaten to a considerable extent, orthopterous insects amount- ing to about thirty per cent. of the year’s food. Flies, ants, and “other hymenopterous insects are taken in small quantities. The nestling birds are fed chiefly with smooth caterpillars and grasshoppers, their stomachs probably being unable to endure the hairy caterpillars. All in all, the cuckoos are of the highest economic value. They do no harm and accomplish great good. If the orchardist could colonize his orchards with them, he would escape much loss. That curious member of the cuckoo family known in the Southwest as the Cuaparrat Cock, or RoaDRUNNER, is especially noted for its speed on foot and its droll manner of darting about in pursuit of its food. Its economic interest lies wholly in what it eats. Insects, snails, lizards, small birds, and snakes are food for it. It is even credited as an enemy of the rattlesnake. It is occasionally tamed and allowed to go at will about the premises to wage war on mice and other “household pests, though it generally becomes so mischievous that it proves a nuisance rather than a benefit.

Their nocturnal habits, their grotesque appear- ance, their weird and unearthly voices, and their secluded haunts all combine to render them birds of note to the human mind. Our literature is full of allusions to the owl, such allusions, especially in the older writings, being chiefly due to the barn-owl, which in Europe commonly inhabits the belfries and towers of churches and castles. With few exceptions the owls are nocturnal birds, though many of them can see very well by daylight. Their eyes are large and of peculiar structure, the ears are remarkably de- veloped, and the plumage is so soft and fluffy that the birds seem much larger than they really are. Many of the species have a wide distribution, being found almost the world over under the guise of slightly varying geographical races. The nest is generally placed in a hole in a tree, the cupola of a building, or some other sheltered situation. The eggs are whitish and vary from two to eight or more, according to the species. The owls live wholly upon animal food, which, as a rule, is captured alive. Small animals, especially mice and gophers, birds, frogs, reptiles, and the larger insects form their staple diet, though fish are sometimes caught in the water and eaten. The indigestible portions of the food are regurgitated in the form of small pellets, in which the hair and bones of the victims are all present. On this account it is an easy matter to determine precisely the food of a given species of owl by examining the pellets in the nest or beneath the roosting-site. Large numbers of such pellets have been examined by com- 195 196 BIRDS IN THEIR RELATIONS TO MAN. petent naturalists, both in Europe and America, and the re- sults prove beyond question that the owls as a group are of great value as vermin destroyers. The most complete ac- count of the economic status of these birds as yet published is the report of Dr. A. K. Fisher, of the United States Depart- ment of Agriculture, to which we are indebted for much of the information in this chapter. There is but one North American representative of the family Strigide, the common Bary-Ow1 of the Southern and Western States. This handsome bird is occasionally found as far north as New England on the Atlantic coast, while in the Pacific region it extends northward to Oregon. In most parts of the United States it is not an abundant species, but in California it is said to be the commonest of the owls. It nests in towers or hollow trees, depositing from three to six yellowish-white eggs on the mass of regurgitated pellets which have accumulated in its abode. The barn-owl is a crepuscular or nocturnal bird, hiding during the day and sallying forth in search of prey during the evening. The record of its food is unusually complete, and shows that on the whole it is a very useful species. Of thirty- nine stomachs examined by Dr. Fisher, one contained a pigeon; three, other birds; seventeen, mice; seventeen, other mam- mals; four, insects; and seven were empty. These stomachs were collected from Delaware to California, and contained specimens of the following small mammals: meadow-mice, jumping mice, harvest and house mice, white-footed mice, shrews, cotton-rats, pocket-rats, kangaroo-rats, wood-rats, and pouched gophers. Two hundred pellets from beneath a nest of these birds in Washington, D. C., contained four hundred and fifty-four skulls, of which ‘*two hundred and twenty-five were meadow-mice; two, pine-mice; one hundred and seventy-nine, house-mice; twenty, rats; six, jumping mice; twenty, shrews; one, a star-nosed mole; and one, a vesper- sparrow.” THE OWLS. 197 Mr. J. H. Reed, who has made a special study of the barn- owls in Pennsylvania, says that their food consists chiefly of meadow-iice. A German ornithologist thirty years ago examined seven hundred and three pellets regurgitated by barn-owls. Of the two thousand five hundred and fifty-one skulls found, one thousand five hundred and seventy-nine belonged to shrews, nine hundred and thirty to mice, sixteen to bats, one to a mole, nineteen to English sparrows, and three to other birds. In the Southern States the barn-owl feeds very largely upon the destructive cotton-rat, and in California the main staple of its diet is the pouched gopher, an abundant and vexatious rodent, and the ground-squirrel, a related pest. All accounts agree in showing that it is a rare and exceptional trait for the barn-owl to feed on small birds. The Suort-karReD Ow is said to have the greatest geo- graphical range of any land bird. It is found in all the principal divisions of the globe except Australia, and is com- mon throughout most of North America, going northward to breed in summer and returning southward for the winter. It prefers open to wooded country, and in many regions is the most abundant of the owls. Its food consists principally of field-mice, but moles, shrews, gophers, small rabbits, crickets, grasshoppers, beetles, and rarely small birds are also eaten. Fully ninety per cent. of the stomachs of about fifty specimens examined in the Department of Agriculture con- tained nothing but meadow-mice. In England this species is noted as being one of the chief agencies in subduing the up- risings of field-mice that periodically occur. The Barrep Owt is a larger bird than either of the pre- ceding species. The typical form is found in eastern North America, while closely related representatives inhabit the West and Southwest. It is generally accused of being a serious enemy to poultry, and in southern regions where 198 BIRDS IN THEIR RELATIONS TO MAN. fowls roost in trees it probably does considerable damage ; but of the one hundred and nine stomachs examined by Dr. Fisher only three contained domestic fowls, while in one was a pigeon, in another a ruffed grouse, and thirteen contained smaller birds, including screech-owls, sparrows, and a red- bellied woodpecker. Mice were found in forty-six stomachs ; rats, red squirrels, and chipmunks in eighteen; insects and spiders in sixteen; crawfish in nine; frogs in four; fish in two; a lizard in one; while twenty of the stomachs were empty. Audubon records the fact that these owls are very fond of a brown wood-frog found in Louisiana. ‘ Dr. C. Hart Merriam took the remains of at least a dozen red-backed mice from a single specimen killed near Moose River in northern New York.” “In summing up the facts relating to the food habits of this owl,” writes Dr. Fisher, ‘it appears that, while the general statements of certain authors, especially the earlier ones, charge the bird with the destruction of poultry, game, and small birds, such destructive habits are comparatively un- common. That it does occasionally make inroads upon the poultry-yard and does more or less damage among game- birds is true; but the systematic collection and examination of a large number of stomachs show the exceptional char- acter of such acts and reveal the fact that a large part of its food consists of mammals. And it is to be noted that among the list are some of the most destructive rodents that the farmer has to contend with. If a fair balance be struck, therefore, it must be considered that on the whole this owl is beneficial, and hence should occupy a place on the list of birds to be protected.” The barred owl makes its nest in hollow trees or among the upper branches. It often uses the deserted nest of a crow or hawk for the purpose, remodelling ‘it slightly to suit the new occupant. The complement of whitish eggs is usually two or three, but four or five are sometimes found. These 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 Screecu-Ow1 is one of the best-known and most abundant of the group: it inhabits 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- BCREECH OWL: ter weather it stores Pe ranees er 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 sparrow 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 200 BIRDS IN THEIR RELATIONS TO MAN. found the bodies of two English sparrows and one field- mouse. ; The Lone-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; five, other small mam- AMERICAN LONG-EARED OWL. mals ; sixteen, small (After Biological Survey.) : F birds, one being a quail; while one contained insects and fifteen were empty. Dr. B. H. Warren 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; while in Oregon 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 ELr Ow, 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 Acapian or Saw-Wuet Ow1, 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, with 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 Hornep Owt is found over almost the whole of North America. In strength and ferocity it has no equal among our rapacious birds. Of all the owls which we have, itis the only one distinctly harmful. During the day it keeps very closely hidden, more to escape persecution from crows and other birds that delight to torment 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 woods 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 specimen examined by us had eaten a caterpillar (Hacles imperialis) in addition to a chicken. 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. The writers have known an owl to dispose of two guinea-hens in one night, leaving only a few bones and a lot of feathers on the snow to tell the tale. In his account of THE OWLS. 203 this owl, Dr. C. Hart Merriam’ states that he has known one to decapitate three turkeys and several hens in a single night, leaving the bodies fit for the table. It occasionally catches fish. Of one hundred and twenty- seven stomachs of the great horned owl that 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 emply. In the arctic regions ef North America the beautiful Snowy Owt is a rather common 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 various 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 left un- molested when it visits us. The Burrowine Ow 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, chipmunks, gophers, mice, and shrews. It also feeds on grasshoppers, crickets, beetles, scorpions, and centipedes. In localities where prairie-dogs 1 Birds of Connecticut, 1877, p. 97. 204 BIRDS IN THEIR RELATIONS TO MAN. are plentiful, the young ones form a large share of the food of this species. The old story of how these owls live in harmony with prairie-dogs and rattlesnakes, all in the same burrows, is a BURROWING OWL. (After Biological Survey.) myth. The owl and the snake are both parasites, the dog, an unwilling host, being forced to yield its home and often its life to its unwelcome guests. SPARROW-HAWKS. (After Biological Survey.) CHAPTER XVIIL THE HAWKS, EAGLES, KITES, AND VULTURES, THE HAWKS. Tue Sparrow-Hawk is one of the most abundant species of its family in many parts of North America. It is a small and handsome hawk, and breeds throughout the United States, as well as in Mexico on the south and in Canada on the north. It goes south in autumn, occasionally passing the winter as far north as southern New York. Its nest is built in holes in trees, those made by the larger woodpeckers often being appropriated for the purpose, and five eggs are usually deposited. It is a valuable bird and deserves protection and encouragement. Dr. A. K. Fisher, who made a special study of its economic relations, writes that it ‘tis almost exclusively insectivorous, except when insect food is difficult to obtain. In localities where grasshoppers and crickets are abundant, these hawks congregate, often in moderate-sized flocks, and gorge themselves continuously. Rarely do they touch any other form of food until, either by the advancing season or other natural causes, the grasshopper crop is so lessened that their hunger cannot be appeased without undue exertion; then other kinds of insects and other forms of life contribute to their fare, and beetles, spiders, mice, shrews, small snakes, lizards, or-even birds may be required to bring up the balance.” In the sparse pine woods of the sandy barrens of southern Florida.we have found the sparrow-hawk one of the com- monest of winter birds, and much more abundant than any other hawk. One of its favorite methods of obtaining food there is to perch in trees on the outskirts of the forest fires that frequently occur, and catch the grasshoppers, lizards, and other animals driven from cover by the flames. At such 205 206 BIRDS IN THEIR RELATIONS TO MAN. times lizards enter largely into the bird’s diet. Professor King reports that of seven sparrow-hawks which he examined in Wisconsin “two had eaten two mice; four, twenty-five grasshoppers; three, twenty-five crickets; one, six beetles; one, five moths; and one, two hairy caterpillars. One was seen to take a young robin from the nest and one to capture another bird not identified.” Ten Nebraska specimens ex- amined by Professor Aughey had eaten large numbers of insects, comparatively few being locusts; three of them had also eaten mice, three others gophers, one a rabbit, one a quail, one an unidentified bird, and one some frogs. All the evidence goes to show that the sparrow-hawk preys only to a limited extent upon our native insectivorous birds. The Broap-wincep Hawk is comparatively a common species throughout eastern North America, spending the winter south of the fortieth degree of latitude, but coming north for the summer. It breeds in trees, building a bulky nest similar to that of other common hawks; and feeds on mice, frogs, small snakes, toads, crayfish, chipmunks and red squirrels, earth- worms, and many insects,—making a specialty among the latter of the large caterpillars of the sphinx- and emperor- moths, such as the cecropia-caterpillar so often destructive to shade-trees. This is one of the few birds that venture to attack these formidable-looking creatures. This hawk very seldom attacks poultry or small birds. Several species of the birds of prey are of great benefit to man as insect destroyers. In the Western States none of them surpasses in this respect the common Swarnson’s Hawk, a large bird which during the late summer and early autumn months feeds to so great an extent on grasshoppers and their allies that it might well be called a grasshopper hawk. The evidence on this point is abundant and conclusive, as is also that in regard to the work this bird does in destroying ground- squirrels (Spermophiles) and related pests. Flocks of several hundreds of these hawks have repeatedly been seen foraging THE HAWKS, EAGLES, KITES, AND VULTURES. 207 for grasshoppers, and from examinations of many stomachs it is safe to say that each bird during the grasshopper season destroys at least two hundred of the pests each day. They very rarely attack poultry or birds of any kind, and unques- tionably deserve the protection of the husbandman. Of the various birds to which the name hen-hawk is occa- sionally applied it is least deserved by the Rovcu-teccep 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 insects 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 field-mice are reported as the staple diet, while cotton-tail rabbits, gophers, and other animals are also included in the bill of fare. The rough-legged hawk is a northern bird in summer, as a rule visiting the United States only in winter. It is said generally to keep south of the snow line in order to capture 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 Rep-snoutpereD Hawk is common in the Eastern States and closely related races are found in the South and West, though the bird is absent from the Great Plains region. It breeds throughout its range, the nest being built in early spring in the upper branches of some tall tree, and a brood of from three to five young being reared. This is a heavy, slow-flying hawk, an adept at catching mice 208 BIRDS IN THEIR RELATIONS TO MAN. and frogs, but paying little attention to poultry or small birds. 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 mammals, 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 had eaten 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; while fourteen stomachs contained nothing. Such a showing as this ought to convince any one of the general beneficence of a bird whose food consists of sixty-five per cent. of mice and not more than one per cent. of poultry. The typical form of the Rep-raitep Hawk is found in eastern North America, ranging west 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, EAGLES, KITES, AND VULTURES. 209 Our knowledge of the feeding habits of this species is unusually complete. Besides the isolated observations of a large number of competent observers, we have the results of the special studies of Dr. B. H. Warren, in which 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 Prov- inces, ranging from ————— ee Ontario to Florida and pe 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. Fisher’s results as to poultry were similar; fifty-four out of the five hundred and sixty-two specimens contained poultry or game-birds. Various other birds, as the robin, mourning- dove, crow, shore-lark, king-rail, meadow-lark, oriole, blue- bird, grackle, screech-owl, and several species of sparrows, were found in fifty-one stomachs. Mice—including the house, meadow, pine, white-footed, harvest, and Cooper’s mice—had 14 RED-TAILED HAWKS. (After Biological Survey.) 210 BIRDS IN THEIR RELATIONS TO MAN. been eaten by two hundred and seventy-eight 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 offal 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 communities. There are three species of hawks whose 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 obloquy which rests upon the family as a whole. They are all trimly 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 Swarp-suinnep 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 feed on birds. Dr. Fisher examined one hundred and seven stomachs which contained food; in six of them were the remains 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 chickens there were evidences THE HAWKS, EAGLES, KITES, AND VULTURES. 211 of the presence of the quail, robin, oriole, swift, bluebird, downy woodpecker, flicker, cow-bird, mocking-bird, cat-bird, oven-bird, hermit-thrush, mourning-dove, chickadee, snow- birds, and various wrens, warblers, buntings, and sparrows, including the English variety of the latter. No bird with such a record deserves protection. Cooper's Hawk may be considered a larger type of the sharp-shinned species. It measures from fourteen to twenty inches in length, is found throughout North Amer- [ ~ 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. Fisher 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 ruffed grouse, and on the list of other birds one finds the chewink, purple grackle, meadow-lark, flicker, nuthatch, hermit-thrush, dove, robin, snow-bird, mourning-dove, and various warblers and sparrows. COOPER’S HAWK. (After Biological Survey.) 212 BIRDS IN THEIR RELATIONS TO MAN. This species is, as Dr. Fisher remarks, “ pre-eminently a chicken-hawk. Its devastations in this direction are much greater than those 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 GosHawx 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, quail, 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 Ducx-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 the 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 the vicinity of a poultry yard,—a rare event,— the chickens are liable to suffer severely. Among its other feathered victims one finds the meadow- lark, robin, cat-bird, mourning-dove, gray-cheeked thrush, and various warblers and sparrows. In Florida it feeds largely upon 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 Fisu-Hawk, is of chief interest on account of its relations to the bald eagle, which so persistently robs the osprey of its prey in mid-air. The fish-hawk is chiefly a bird of the shore-line, where it finds its food abundant. The Marsu Hawk, sometimes also called the Marsu Har- rier, inhabits almost the whole of North America, breeding Photographed from life by Dr. R. W. Shaufeldt. HEAD OF OSPREY. THE HAWKS, EAGLES, KITES, AND VULTURES. 213 from Cuba to Alaska. It is most abundant in the prairie . States. The nest is placed upon the ground in marshy situ- ations, where grass and sedges help conceal it. From four to six young are reared in each brood. This is 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 offal 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, when 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. Bap Eacies 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 nunibers during 214 BIRDS IN THEIR RELATIONS TO MAN. the winter months, their food relations are somewhat modified, as is indicated by the following extract, written by Dr. William 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 water-fowl, especially coots (Fulica americana?), that frequent this vicinity during the winter, and which form the principal part of their food, though 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.” The Goupen Eacie 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 thrilling 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 crippled by a hunter. If this were an abundant species, it would plainly be a harmful one; but, owing to its 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 Swattow-tTaiLtep Kurs, 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 five 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 them. 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 the 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 Turxey-Buzzarp and the Buacx 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 that 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 themin the Florida Keys sucking the eggs and devouring the young of herons and cormorants. As another offset to the good these birds do, mention should be made of the fact that Mr. E. B. Williamson has suggested that they are ‘‘ doubtless an important factor in the spread of some diseases,—hog cholera, 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 JA wit 71,8 ish TURKEY-BUZZARDS, (After Brehm.) earth; this was covered with brushwood, allowing the air to pass freely beneath it so as to convey the effluvium far and wide.” Although left for nearly a month, with hundreds of vultures passing over it daily, none of them discovered its presence. Another time a perfectly dry stuffed deerskin was placed in a field, and immediately attracted the vultures, which were of course unable to get any food. To test still further whether the birds were attracted by sight alone, ‘a THE HAWKS, EAGLES, KITES, AND VULTURES. Q17 coarse painting on canvas was made, representing a sheep skinned and cut open. This 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 fifty times, with the same result.” In other cases pieces of meat were placed beneath tables and other pieces THE BLACK VULTURE, (After Brehm.) on top. The 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 action is seen and understood by others in the vicinity ; these fly immediately to the spot. As they start they are seen by others, which in turn signal to more dis- tant birds, so that in a very 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 the latitude of 40 degrees, and occurs in summer still farther north. For 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 the 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 Cathartide, 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.

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 worth 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, with horses and wagons, guns and ammunition, had 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 place 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 which ‘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 pourin. The fires were lighted, and a magnificent as well 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 t6 the ground destroyed hundreds of the birds beneath, forcing down the dense groups with which every stick was 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 PIGEONS, GROUSE, AND SHORE-BIRDS. 221 I 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 which they arrived the evening before, and by sunrise all that were able to fly had disappeared. The howlings of the wolves now reached our cars, and the foxes, lynxes, cougars, THE MOURNING-DOVE. (After Biological Survey.) bears, raccoons, opossuius, and polecats were seen sneaking off, whilst eagles and hawks of different species, accompanied by a crowd of vultures, came to supplant them and to enjoy their share of the spoil. “Tt was then that the authors of all this devastation began their entry amongst the dead, the dying, and the mangled. The pigeons were picked up and piled in heaps until each had as many as he could possibly dispose of, when:the hogs were let loose to feed upon the remainder.” 229 BIRDS IN THEIR RELATIONS TO MAN. 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 with 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 Movrnine or Carouina 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 weeds than on cultivated grains. Professor King took four thousand and sixteen seeds of pigeon-grass (Setaria) from the stomach of a single bird, while from that of another seven thousand five hundred seeds of oxalis have been taken. The young are fed with the regurgitated vegetable food of the adult. The Banp-taitep Pigeon (Columba fasciata), which ranges westward from the Rocky Mountains and southward through Mexico, is about the only pigeon that we now have worthy to be called game. It is sought by sportsmen both for its flesh and for its gamy qualities. Its food consists of grain, berries and other soft fruits, and buds of certain trees, notably of balsam-poplar. THE PARTRIDGE AND GROUSE. The Bos-Wuire, or Quai, is found from Minnesota to Texas and eastward. It is favorably regarded by epicures and gunners and deserves the good will of those interested in agriculture. It lives in fields and ‘pastures and during the summer feeds largely on insects. Colorado potato-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, which is always taken in greater or less quantities, becomes the staple form of diet. This includes grains, seeds, THE PIGEONS, GROUSE, AND SHORE-BIRDS. 223 nuts, berries, and green leaves. Twenty-one quail taken in Nebraska between May and October had all eaten seeds and from thirty-one to forty-seven insects each. 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-fivé oats, twelve barberries, seven small seeds, and THE BOB-WHITE OR QUAIL. nine leaves of white clover. The oats had evidently been taken from horse droppings in the road near by. According to the studies of the Department of Agriculture, ‘‘seeds of rib-grass, tickfoil, and berries of nightshade are sometimes eaten, and pigeon-grass and smartweed are frequently con- sumed in large quantities. The amount of grain food in the stomachs thus far examined is surprisingly small, while the proportion of weed seed is astonishingly large, in some cases 224 BIRDS IN THEIR RELATIONS TO MAN. crops and gizzards being literally gorged with hundreds of seeds of ragweed.” ! The Rurrep 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 RUFFED GROUSE. “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 larve 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. 281. THE RED-HUMPED OAK-CATERPILLAR. u, larva ; b, pupa; c, moth, wings expanded ; d, moth at rest. 15 226 BIRDS IN ‘THEIR RELATIONS TO MAN. 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 dantage to fruit- trees by eating the buds in winter. The extent of the injury which 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 albifrons). The other two were shot from the same flock at the sarne 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 Prainie-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. 224 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 autumn 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 Dusxy Grouse and its closely allied races, the Sooty GrovusE and Ricuarpson’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 three pounds, 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 are so handsome as the several species of plumed partridges found west of the Rocky Moun- tains. The Mountain Partrineg, found along the Pacific coast from San Francisco to Washington, and the Cairornia 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 qualities, 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 hills, 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 Rine-neck Prover 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 Kituperr, or the KriiprEr Piover, 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- worms, 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 Photographed from life by Dr. R. W. Shufeldt. MOUNTAIN PARTRIDGE. ADULT MALE. THE PIGEONS, GROUSE, AND SHORE-BIRDS. 229 band of birds which like 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 Gotpen Prover breeds in the Arctic regions, but in the migration season it is very abundant and is highly esteemed asagame-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 that are useful as insect destroyers. At the head of the list stands the American Woopcock, 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 1 Quoted by Wilson Flagg, Agr. of Mass., 1861, pt. IT. p. 55. 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 the tall 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-wood forests, or among the high shrubbery of neglected pastures. Here they turn over leaves, looking for hidden insects and larve 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 earth. “The growing scarcity of woodcock,” writes Dr. A. K. Fisher, ‘is a matter of serious alarm, and one demanding 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 with 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 shot 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 flushing 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.” “HOO0GOOM NVOINANVY FHL WPLMUS “A HT fq afy mosl paydrsbojoyg 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 summer 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 Witson’s Swipe is similar in its make-up to the woodcock, but it chooses different abodes. This snipe is found in open wet places, in meadows, 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 Snire, or Dowitcuen, 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 Marstep Gopwir 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 leeches. The Hupsonian Gopwir is somewhat smaller than the last, and, though more widely distributed, is far less common. The WitteT occurs as a summer resident throughout the country, though more commonly coastwise. It is a large, noisy species, not different in its food habits from shore-birds in general. It follows marshes, often annoying 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 YeELLow-Lecs 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 Uptanp Sanb-PiPeR, commonly called the UpLanp PLover, is something of an anomaly, being fitted out with a wader’s bill and legs, yet avoiding the water. 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 Lone-BiLLED CurRLEW, 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, GROUSE, AND SHORE-BIRDS. 233 frequent uplands in search of bramble-berries, upon which they get very fat. The Hupsonian and Esximo Curtews are migrants only, breeding in high latitudes and mostly passing 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 thern 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 which enable them to swim. They are usually seen floating lightly about upon the water, catching flies in the air or gathering larvee from the water; on shore they take worms and various aquatic forms found there. The best-known representative of the family is Witson’s Puatarope, which is abundant in the Mississippi Valley and westward, though rarely occurring east of Illinois. Two other species, the Rep and Norruern PHa.aropes, 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 table. They are very 234 BIRDS IN THEIR RELATIONS TO MAN. shy and hard to flush, depending 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, Kine, and Vireiia Rats, 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 different 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 Carouina Rai, the Brack Ram, and the Yettow Crake, have rather THE PIGEONS, GROUSE, AND SHORE-BIRDS. 235 thick bills, shorter than the head, and feed more on vegetable matter. The only one of the group common enough to be of any special importance is the Carolina rail. Thousands of the latter are killed annually in the Atlantic States for market. They feed largely on seeds in the fall, when they become fat 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 Purpte GALLINULE is a resident of the South Atlantic and Gulf States. The Fiorina GaLiinuze 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. The cranes are large waders resembling the herons in out- ward appearance, but differing from them in structure and habits. The Wuoopine Cranes is chiefly a migrant, moving up and down the Mississippi Valley with the changing seasons; it is an omnivorous feeder. Audubon found 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 peas and dig up potatoes, which they devour with remarkable greediness.” In April they had ieft the fields 236 BIRDS IN 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 Sanp-HitL 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 Wuire Isis 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 that 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 Woop Stork, better known as the Woon Inis, 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, GROUSE, AND SHORE-BIRDS. 237 The Birrern, or STAKE-DRIVER, is common throughout the country. Itis a solitary bird, inhabiting weedy marshes, but known by its peculiar 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 Biuz 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 larve, tadpoles, small fish, and frogs. The Great Wuire Ecret is found in the Southern States, but in much smaller numbers than 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 the 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 practice 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 the 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. Tue members of this group 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, but 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 Mattarp Duck is an abundant species, except in New England, where it is rather rare, being replaced by the 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 Brack 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 Trats, blue-winged and green- winged, are two small ducks well known through the country, except in New England, where they are not so common as elsewhere. Being little, they are of less importance 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 are 239 240 BIRDS IN THEIR RELATIONS TO MAN. inland birds, feeding upon insects, mollusks, nuts, grass, and grain. In the West they visit the vast grain-fields in harvest- time and soon get in excellent condition for the table. “The Woop-Ducx, or Summer Duck,” writes Dr. A. K. Fisher, ‘cis 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, where 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, scattered woodlands, and, except during migration, it is rarely met with about open bays or large 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 ( Vallisneria), 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 DUCK. than those from other localities. Except for its peculiar appe- tite in the one instance of wild celery, the canvas-back’s menu shows ho appreciable difference from that of the group just treated of. An associate and relative of the canvas-back is the Rep-HEap, another excellent table bird. In both size and color there is such a strong resemblance between the two that dishonest market-men have been known to impose on customers, not well informed in ornithological matters, by selling red-heads for canvas-back. The Rine-neck and the Greater and Lesszr 16 242 BIRDS IN THEIR RELATIONS TO MAN. Scaurs belong to the same genus as the canvas-backs and red-heads, but they feed more on mollusks and other forms of animal life and are less palatable. The WuisTLER, or GOLDEN-EYE, OLD Squaw, BuTTER-BALL, or Dipper, and Ruppy Dvcx 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. Svurr-pucks or ScotTers of various species are abundant along the coast from autumn till spring. HEAD OF SURF SCOTER DUCK. 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 E1per and Kine Ener 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, known 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” tells THE WATER-BIRDS. 243 how the down is obtained in Iceland and Norway, and inci- dentally carries an impressive lesson concerning 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 fine 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 stones, 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 Fisu-pucxs, or Mereansers, 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 far north as possible, usually in the larger rivers which have a current swift enough to defy frost. ‘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 WuiITE-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-Goosz, common in the interior, and the Canapa or WILD Goosr. 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, while the other species, the WuIsTLINe 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 finny 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. Wuite 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-Birp, 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, which 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 Waite Petican is common in the Southern States, rang- ing well up 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 within. 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 Peuican, 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 GULLS. The Frigate Birp, or Man-or-war Biro, is a maritime species, having its four toes webbed together ; it resembles in this par- ticular the gannets, darters, cormorants, and pelicans; indeed, it has a double relationship to the pelicans, 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 fish for themselves when necessity demands it, but they much prefer 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 waters. Fishermen watch their move- ments and are often led to good luck by them. The Manx government protects them because of their usefulness 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-BackEeD 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 prefers 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 Herrine GuLL, a much commoner species, that is found both coastwise and interiorly, has similar good habits. A stomach examined by Dr. Coues contained the remains of a marsh-hare. Two which were examined by Professor Aughey had grasshoppers, fish, and mollusks. One shot by us had eaten only refuse 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 Kirtrwaxe Gut, 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 Rine- 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 Guit 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 Nuttall were gorged with ants, ants’ cocoons, and moth pupe. FranK.in’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 ofits 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 woman, 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 Buiack Skimmer is a peculiar tern-like bird, which has its lower mandible about an inch longer than the 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 Jazcers 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 the 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 Perrets, 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 Avxs 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 Purrin, 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 Aux, 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 take pretty good care of itself in the water, when on land it was at the mercy of any foe larger and more THE WATER-BIRDS. 251 powerful than itself. The 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 this 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 the 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, where ina 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 reénact 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 weight 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 water. 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 Greses 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 Dascuicx, or Prep-BILLED Grese, 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 Rep-necxep Gress, the Hornep Gress, and the Earep Grese. The first two are found at large throughout the country. The eared 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 other 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 upon to satisfy the demands of fashion, the breast portions of their skins being prized by milliners. CHAPTER XXIL THE CONSERVATION OF BIRDS. I. NON-GAMEBIRDS—THEIR DESTRUCTION, PROTECTION, AND ENCOURAGEMENT. Accorpine 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 native fauna. Some birds have found the new dis- pensation better suited to their wants than the old; others have changed their habits 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 phcebes 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 when 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. 257 they could stand the weather, but hunger and cold combined they could not 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 the 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 with 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 who 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, who 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 is annually 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 Stream a few years ago mentions a dealer who, during a three months’ trip to the 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 would 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 which the greater part are cut up for millinery purposes. 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 comprised 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 is 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 that are sacrificed on the altar of fashion. The universal use of birds for millinery purposes bears suffi- cient testimony to the fact. Yet it is probable that most women who follow the fashion seldom appreciate the suffer- ing and the economic losses which it involves. 262 BIRDS IN THEIR RELATIONS TO MAN. A few years ago the 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 be 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 are displayed daily. Besides the reed-birds, robins, meadow- larks, and blackbirds that one would expect might be found, there occur 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, which does not occur in California. They are most commonly the horned lark (Otocoris), 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 au- thorities interested in bird protection.” In the South all sorts of small birds appear 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, cardinals, and almost all small birds, even swallows, can be found in the markets.” 1 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 bigger; but among true sportsmen they have 1 See W. T. Hornaday, 2d Ann. Rept. N. Y. Zool. Soc., p. 86, 1898. 264 BIRDS IN THEIR RELATIONS TO MAN. been put on the ‘retired list.” Nevada is the only State in which flickers are legally reckoned among game-birds. Larks are so classed in less than half a dozen States. Event- ually all birds of this sort, with the exception of bobolinks and blackbirds in certain localities where they are noxious, will be struck from the game list in practice as well as in theory. 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 continued on the islands off New Brunswick and northward. The 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 (Larus 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 Behring 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. 2 Yearbook, Dept. of Agr. for 1899, p. 271. THE CONSERVATION OF BIRDS. 265 ege-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 occidentalis) and murres, or California guillemots (Uria troile Californica). For nearly fifty 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 were shipped regularly once or twice a week. The main crop was gathered on South Faral- lone, the principal island, and mainly from the ‘great rookery’ at the west end. The birds lay only one egg, which 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 were not perfectly fresh. The ground was then gone over every day, and the eges were systematically picked up and shipped to market. The business was in the hands of Italians and Greeks, who were also engaged in fishing, and, although a dozen or fifteen ‘egeers’ were employed on the islands, the number of eggs gathered was simply enormous. It is said that in 1854 more than five hundred thousand eggs were sold in less than two months, and that between 1850 and 1856 three or four mill- ions were taken to San Francisco. . . . Since then the value of the eggs has declined, and the number has fallen off con- siderably. In 1884 there were gathered three hundred thou- sand, in 1896 about one hundred and eight thousand, while in 1896 the crop was reduced to a little less than ninety-two thousand.” As a cause of reduction in the number of sea-birds, egging undoubtedly is entitled to first place. Millinery shooting, though equally destructive in operation, was begun at 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 immi- 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 standing. In that year both Connecticut and New Jersey protected most of the com- mon small birds and their eggs by fixing a fine 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 States, numbering about ninety —have come in for statutory shelter in several States. There is a deeply-rooted prejudice against them, however, that can- not be overcome in one generation, even by figures; the acts THE CONSERVATION OF BIRDS. 267 of the evil few have so blackened the reputation 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. Utah alone grants protection to the whole tribe. [Illinois protects all but “chicken-hawks.” Rhode Island protects fish-hawks. Three other States have pre- scribed fines for killing bald eagles. The turkey buzzards (Cathartes aura), which prefer carrion to freshly-killed meat, are useful as scavengers and are protected in the District of Columbia and in eight States and Territories. 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 primarily intended for game has in a few instances afforded protection to all birds. Laws prohibiting 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 the vicinity of some of our larger cities trapping native song-birds to sell as pets 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 wild state usually prove good missionaries. People that keep a tame bird a year or two are usually friendly 9 the race thereafter. Although every State and Territory except 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, excepting that of an indirect character, like the Lacey Act, which will be noticed in the next chapter, would be unconsti- tutional, and is therefore impossible, though it would 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 pre- pared 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 CONSERVATION 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’ instruaments,— 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 not able 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 expected very soon, it remains to scatter information about birds every- where, so that laws may be respectéd, 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 youth in birds cannot be over-estimated. It results in a double benefit, for the birds will be held in higher esteem and the children 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 taken up the 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 will 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 policy of taking eggs will thus be overcome. There should be no honor in failure. None should receive credit who are not able to report the young safely on the wing. Of course the teacher should have a lively interest in the matter himself, and be able to advise in many ways, but this much granted, the plan will work.' 1JIn this school work The Bird Calendar, by Clarence Moores Weed, will be found useful. It enables the pupil to keep his record clearly and systematically. It is published by Rand, McNally & Co., Chicago. “ANCIaLAVd VINYOAITVO WPLUS MMT Ag af moss pi aydnsBojoyg al CHAPTER XXII. THE CONSERVATION OF BIRDS (Conctupep). II. THE GAME-BIRDS. Tue term game-birds is at present held to comprise the fol- lowing four orders of birds: Anseres, ducks, geese, and swans ; Paludicole, cranes, rails, coots, and gallinules; Limicole, shore birds; Galline, grouse and quail. The members of the order Columba, 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 such 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 birds be secured to satisfy bodily needs? was the sum of it. After a steadily-increasing drain for many years, we find ourselves confronted by a different phase, not destructive, but conserva- tive. The question now stands, How can extermination be prevented ? Aboriginal weapons were so crude and furred animals so much more desirable on account of their skins that birds were not seriously persecuted by the red men. The pioneers were better equipped. Like the Indians, they depended on game for their meat supply, and early appreciated the sapid qualities 271 (fening porbojng wif) “aowrarp yore ul ‘os AjI80u JO “TAIOJTUN eq AUT SUOSeES OUTES 423 podnodg OB oI" BOLIOJLLIOT, PUL s9}4Ig CTL, “Ea0D MOOTIVH AM AaSOdOUd SNOISIAIG ONIMOHS dVW s OS 4 wyeeerror= S, -" “NNGL ‘O'N “AM 272 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 wild meat were sweet to his palate. What wonder, 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. must ascribe the enormous quantities of game-birds that 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 the 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 title 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 making it so. When this country was first settled predaceous animals were troublesome. Bounties were offered for their scalps. For the most part they 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 find them 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 pleasure. To be a successful hunter of wild fowl one must have a taste for it, 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 with a weak mind. THE CONSERVATION OF BIRDS. QT The number 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 public sentiment by appeals 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 selfish 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 faras 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 was 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 with traps, nets, and swivel-guns. Asa specific 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 pilgrim 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 common practice. They brought but a trifle per dozen, yet many men were 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 the exterminated species alone that deserve attention ; indeed, they are “spilt milk” and may as well be forgotten, unless we can turn their fate to account in perpetu- ating those that are left. The worst sufferers in New Hamp- shire to-day 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 multiply. 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 when 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 was not wholly checked, and further measures were taken. It was made an offence to send dead grouse b-----, 1 OKL ' tT H MAP ILLUSTRATING THE NEED OF GREATER PROTECTION FOR WILD DUCKS.

Public opinion favorable to the protection of game has been steadily growing. A State game and fish commission, 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. Nineteen prohibit market hunting or the sale of game at all times; forty prohibit export; fifteen require that non-residents shall procure gun licenses, and several of them make the law apply to residents as well, though to them licenses are issued at a nominal rate. In twelve States there are laws limiting the number of birds that may be killed by one person ina day. Although the need of game protection was a long time in impressing the public mind, when once aroused, the sentiment in its favor rapidly gained strength. 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, the laws as they now stand is the lack of uniformity which they present. 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 ariver. There is injustice when slaughter must cease at an arbitrary line which has no natural significance. Those who kill illegally under THE CONSERVATION OF BIRDS. 283 such circumstances 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 com- plaints 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 lowa and her imme- diate neighbors north and south, Minnesota and Missouri. The close season for ducks in Iowa is April 15 to September 1; in Minnesota it is January 1 to September 1; and in Mis- souri April 1 to October 1. Iowa gunners are allowed to kill ducks six weeks longer than Missouri gunners, and thirteen weeks longer than Minnesota gunners. If ducks were perma- nent residents such discrepancy would 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 are no nearer alike. Neither are game laws of other contiguous States better in this respect. In the statement of close seasons in the different States and territories issued by the Department of Agriculture’ there are not three successive States with uniform laws relating to a single game-bird, with the exception of Utah, Idaho, and Washington, which agree in protecting grouse and prairie chickens. This condition of things is manifestly wrong, and so long as it continues the laws in question are certain to be violated. Popular sentiment will not uphold them. It is not practicable to police every bit of woods, 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 of a certain line what is openly and legally practised on the other can lead to but one outcome—defiance.

THE CONSERVATION OF BIRDS. 285 is no reason why States should not and cannot agree to concerted legislation. 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 itis 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 pro- 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 chapteris 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 is worth trying, if not in detail, at least as a working basis. Undoubtedly as soon as those interested in the preservation of game thoughout the Union are better organized, some such scheme for securing a reasonable uniformity will be carried into effect. 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 included in the duties and powers of the Department of Agricul- ture. 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 286 BIRDS IN THEIR RELATIONS TO MAN. propagation, uses, and preservation. The importation of for- eign wild animals and birds without a special permit from the 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, when 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 laws that would apply in case the birds were pro- duced in that State. This act is designed to supplement State laws and to give a double check to transportation of game by bringing to bear on each transaction the laws of the State. 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 be of appreciable assistance in repopulating the 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 CS ee 2 ae ee! STATES (DOTTED ) WHICH PROHIBIT EXPORT OF GAME. (After Biological Survey.) 287 288 BIRDS IN THEIR RELATIONS TO MAN. by Mr. E. Knight Sperry, of that city. Mr. Sperry first obtained permission to try the experiment from the seven or eight owners of the Jand, 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 well 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 their town for outside parties who for the sake of the birds would be glad to come and pay well for shooting privileges. 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 finding 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. ees r “ STATES ( DOTTED) WHICH PROHIBIT SALE OF CERTAIN GAME AT ALL TIMES. (After Biological Survey.) 289 19 290 BIRDS IN THEIR RELATIONS TO MAN. To review this matter: The stock of wild fowl has reached a low ebb through a long-continued and ever-increasing per- secution and an ever-narrowing breeding range. Two differ- ent motive forces have pushed the persecution,—the market and an inborn love of hunting, the one commercial—a mat- of dollars and cents—the other a natural instinct. The one gratifies the few that earn a meagre living by hunting and the few rich enough to buy; the other may be enjoyed by every man able to leave his place of business if he so elects. The one breeds dyspepsia, the other vigorous health. The one benefits classes, the other masses. Nothing in Euclid is more clearly demonstrated than that their combined drain is altogether too great to be borne. One of them must be put out of action. Which? We have seen that several States have decided already. Selling and killing for sale are pro- hibited. When our uniform laws are come to pass, that clause will be a part of them. Moreover, the number of birds that may be taken in a day will be fixed low. Then spring will be a close season everywhere, and the open season will not be longer than two, or possibly three, months, vary- ing in time according to the habits of the different species. But the main thing, after all, is popular education along this line. There is a contagion in reform. That infection has begun is evident. All having the preservation of birds at heart must help spread it by precept and example. By care the stock may be replenished and the birds indefinitely pre- served,—a continued source of benefit to us and a worthy legacy to posterity. Aside from schools there are certain organizations through which the idea of bird protection is promulgated. Of these the American Ornithologists’ Union, which is devoted to all phases of bird work, is the most comprehensive. Its member- ship embraces many able men who have contributed liberally to current literature upon this subject. The many branches of the Audubon Society, especially arrayed against the use of a ee on i MO. H wane ee 4 Rereese sy ‘ ‘ \ 1. 1 ’ STATES (DOTTED) WHICH LIMIT GAME BAGS. (After Biological Survey.) 291 292 BIRDS IN THEIR RELATIONS TO MAN. bird skins and feathers for millinery purposes, is closer in touch with the people than any other organization of its nature, and as an educational factor is of prime importance. The League of American Sportsmen, although, as its name implies, devoted particularly to the protection of game, also champions the protection of birds. These societies have dealt largely with the ethical and sesthetic side of the question. The economic side has been ably discussed in a number of bulletins and Yearbook articles from the Division of Biologi- cal Survey of the United States Department of Agriculture which have been freely circulated. Thus, while it appears that the decrease in birds is real and the causes numerous and difficult to combat, there is a defi- nite movement against it, which, although late, is now gaining strength and breadth and seems in a fair way to arrive at a successful issue. In some regions very encouraging results have already been reported. GREAT HORNED OWL. CHAPTER XXIII. PREVENTING THE DEPREDATIONS OF BIRDS. Asout the only real interest the average farmer takes in birds relates to methods of preventing the depredations of the few species that are inclined to share with him the fruits of his labors. He accepts their benefits, as he does those of rain and sunshine, as a matter of course. He is free to avail himself of any or all natural products that are favorable to his welfare, so far as lies in his power, and also to avoid such as work him harm, to the same extent. While he may not ex- hibit a proper spirit of gratitude for past favors, when he pre- vents robins and cedar-birds from taking his cherries he is at least practical. The knowledge that crows and blackbirds de- vour multitudes of insects is poor consolation for a ruined crop. When such birds are made to desist from spoliation, not only is the harvest insured, but the birds are thus made to destroy more insects, thereby turning threatened injury into real advantage. To protect crops from the ravages of birds is quite proper and legitimate. It is easy for one who realizes the great value of birds to let his gratitude get the better of his common sense, particu- larly if he owns nothing that birds interfere with. ‘ There is a time to every purpose.” The time to show gratitude to birds is when they need it. The man who values birds be- cause they are useful to him, or because he loves them, is ready to feed them when food is scarce, to offer them nesting facilities, and to prolect them against their enemies. But when his fields are burdened with grasshoppers there is no need for him to allow robins in his berry-patch or blackbirds in his corn. Birds may well be classed as natural resources. From this 293° 294 BIRDS IN THEIR RELATIONS TO MAN. view-point they are not unlike seaweed thrown upon a beach or a muck-pit on a farm. They all have a real value if utilized, though none of them are absolutely essential to a fair crop. It is not less a sign of thrift when a farmer tries to get the most out of the birds about him than it is when he tries to get the most out of his bog or beach. It is true, birds will work to his betterment though he ignore them, while such resources as muck and seaweed yield nothing without his attention. But itis not less true that intelligent effort is as sure of reward in bird-husbandry as it is when applied to resources that are wholly potential without such effort. No prudent farmer will leave the birds out of his plans. He will attract them by ministering to their needs. In his dealings with them he will be guided by the same motives that direct his actions towards his domestic animals. His cattle and his poultry are fed, housed, and slaughtered, all for his per- sonal benefit. So long as his animals are more profitable liv- ing than dead, he cares for them; when they are fit for market, or vicious, he kills them as unhesitatingly as he has nurtured them. There is no reason why this same sort of management should not be applied to birds. An unprofitable oriole should be killed as promptly as an unprofitable sheep. But sheep are not slaughtered for their sins or their infirmities so long as they are of more value living than dead. We do not kill our animals for faults we can correct. The flower-loving house- wife fences round her posy-bed, covers it with brush, or even applies socks to the feet ef the chronic scratchers among her fowls sooner than take off their heads for unearthing seeds. When birds are turned away from marauding by some harm- less device, not only are their lives spared for good work in the future, but they are often turned to better business at the moment. In the study of ways and means for preventing the depre- dations of birds, their ordinary utility should never be lost sight of. That should be the basis upon which all plans for PREVENTING THE DEPREDATIONS OF BIRDS. 295 their regulation are formulated. Moreover, the sins of the individual ought not to be saddled on the whole of its race, as is too often done. Because one red-shouldered hawk, for in- stance, comes to the yard and carries away chickens, the next ninety-nine, which are worthy pursuers of mice and similar vermin, should not be sacrificed for the sins of the guilty one. This is one of the gravest errors to which birds are subjected. When people learn to discriminate as carefully between good and bad wild birds as they do between good and bad domes- tic birds, they will have learned an important lesson, both for themselves and for their feathered benefactors. No person is qualified to deal repressively with birds who has not a thorough knowledge of their habits. Possessed of such knowl- edge, one is able to work intelligently to avail himself of their benefits in fullest measure and to give in return the least pos- sible compensation. The number of birds that are harmful, including those but partially so, is so small that it would seem an easy matter to control them. A few species destroy grain, a few injure trees, a few purloin fruit, and a few steal chickens. These cutprits, all told, are but a small fraction of our avifauna. But though the species that need regulating are few, several of them are so numerous individually that the damage done is sometimes serious. The worst offenders are those that invade grain- fields,—that is to say, crows, blackbirds, bobolinks, jays, and their kin. As grain thieves, crows are most notorious of all, from the fact that they are more uniformly distributed, and also because they pay particular attention to sprouting grain. Their supe- rior size enables them to pull up the planted seeds, and correspondingly large quantities are required to satisfy their hunger. Moreover, crows are in a class by themselves on account of their cunning. By experience they have learned to work on the sly and to avoid the machinations which men would employ to destroy them. 296 BIRDS IN THEIR RELATIONS TO MAN. If crows were less wary, so many would fall victims to the wrath’ of planters that their extermination in the cultivated portions of our country would soon come to pass. They come nearer to living by their wits than any other birds we know. However, their sagacity is not useful to them alone; it makes it possible for us to avoid their villanies by exciting their suspicions. Thus, on the whole, we have reason to be glad that crows are as wise as they are, for we know that their annual consumption of insects is enormous, and that it is unquestionably better to keep them away from the fields a week or two in seed-time than to destroy them, and thus to lose their assistance. We are inclined to believe that if farmers dealt with crows as intelligently as crows deal with farmers there would be vastly less heard about the injury they do. The boy who put his finger to the dim edge of a humming buzz-saw, with the remark ‘It looks as if it were there,” was accustomed there- after to rely more on vision. The man who expects wind- mills, scarecrows, old newspapers, bottles, and sheet tin to protect his field, when he has seen them fail year after year, needs some such lesson as the boy had to make him more acute. ‘Br’er Rabbit” is scarcely more at home ‘in a briar- patch” than crows among these harmless objects, with which they have been acquainted from youth up, and which were never known to harm anything. They soon learn what is dangerous and what is not. If one is shot or poisoned or caught, his comrades remember his misfortune and thereafter avoid the place of its occurrence. They are so apprehensive of danger that they seldom alight near one that is dead, though it may never have been a companion. Crows are accustomed to do most of their foraging very early.in the morning and on rainy days. The farmer who neglects to traverse his corn-land at these times is sure to rue it. They will take advantage of a dense fog, and attack fields they would hardly dare fly over in good weather. PREVENTING THE DEPREDATIONS OF BIRDS. 297 Ordinarily, a field covered with a network of twine strung on poles will not be molested. The twine is usually strung along a few feet from the ground, at intervals of two or three rods. A dead crow thrown down upon the ground or suspended in the air is also almost certain to deter them from venturing near. Poultry placed in boxes heavily slatted, so that the presence of something alive will be manifested without exposing the real nature of the contents, make very good scarecrows. Two or three boxes to the acre, one fowl in each, are sufficient. Another method, one that appeals to taste instead of sight, is to flavor the seed before planting with coal-tar or oil-of-tar, which crows dislike. The corn is first soaked in water, and then enough tar or tar-oil is stirred in to give each kernel a thin coating. Plaster is then added to render the corn more easily handled. Objections to this method are: It does not admit the use of a planter and it retards germination. Though usually effectual, this method is said not to be infallible. Fields that are isolated, so there is no possibility of their being visited by domestic animals, may be protected to a cer- tainty by scattering broadcast a little grain that has been soaked in water in which some strychnine has been dissolved. Poisoned grain should be carefully dried before being put out, in order to make it appear natural to the critical invaders. One or two killed, or even made sick, will settle the crow question for that year. Not a few farmers are accustomed to scatter small quanti- ties of grain—not poisoned—in their fields two or three times a week during the period when crows are troublesome. They say the crows thus obtain all the grain they want with- out pulling up any. They also claim that the crows pay well for the grain by destroying cutworms and other injurious larvee that infest the ground. With highly moral crows this plan is more philosophical than any we know. But some 298 BIRDS IN THEIR RELATIONS TO MAN, crows are depraved. We have even known a tame crow, reared in opulence, exposed to the influence of honest prin- ciples, away from all of its kind, a crow that disdained corn as a food, and yet which, constrained by a hereditary taint of evil, was accustomed to pull it right and left, only to throw it down again. He began to pull corn before he was a year old. After this experience we are not surprised to learn that crows sometimes pull corn when there is plenty above ground. There is certainly more difference in crows than appears as they fly over. Schemes that serve to keep them from molesting corn in one place are frequently useless in another. Moreover, it sometimes happens that a remedy employed with success year after year in a given locality suddenly becomes ineffectual. All naturalists who have had occasion to examine a large series of specimens of any sort of organism are well aware that there is always considerable variation among them in size, proportion, or color, as may be. Now it surely is not preposterous to suppose there are psychic variations as well as bodily variations. Variations in size or proportion of parts, when associated with environment,—climate, soil, food, etc.,— are sufficient to account for geographical races or even species. By analogy it is not difficult to set up a working hypothesis to account for the occasional failure of devices that previously had been successful. The crows that have inhabited a given locality for generations, we will suppose, have a particular fear of the twine put up on corn-land, suspecting it to be a kind of trap for their entanglement. Another race in another region, from a less painful experience with traps, or with enough intelligence to see there is no danger in it, or with too little to suspect any, regards twine with indifference. Again, an old fear may wear off with long familiarity or be removed by an improved temperament, while a fatal lesson or an increas- ing wariness of purely organic origin would account for a new fear. Whatever may be the philosophy of the ways of the crow PREVENTING THE DEPREDATIONS OF BIRDS. 299 there is no doubt that he will bear contemplative observation. Any person interested in agriculture who will make himself acquainted with the habits of this bird will be convinced that it is emphatically worth while to make every effort to avoid its depredations by harmless means. Where granivorous birds other than crows have injurious habits, eternal vigilance appears to be the only means of de- fence. Jays are occasionally thievish when corn is ripe. Blackbirds pick up newly-sown grain and also plunder the matured crop during their autumnal movements when they are in flocks. Bobolinks are mischievous only in the rice- fields, but there they are so bad as to be absolute pests. Fortunately, in most localities none of these birds do appre- ciable harm. Only fields adjacent to woodland are raided by jays. Blackbirds make their head-quarters in marshes during spring and summer, and therefore the range of their operations is restricted. In sections visited by the immense flocks that assemble to spend fall and winter together there is always more or less complaint against them. But it is not always safe, when blackbirds are in a grain-field, to infer they are doing harm. We know an instance in which a farmer killed numbers of them, fully believing them to be eating his grain, but when their stomachs were opened it was found they had taken nothing but insects. It is generally true that the drafts made by any of these smaller grain-eating birds are more than compensated for by the good they do. For this reason they should never be molested unless it is certain they are eating grain. None of these birds are susceptible to any but human scare- crows. Images, traps, cages, dead of their own kind, have no terrors for them. Half a flock may be shot down one day, and the next the surviving half is as likely to visit that field as any other. They do not appear to have an iota of the keen- ness that characterizes the crow. This inferiority in mental capacity is an unsurmountable obstacle to avoiding their dep- 300 BIRDS IN THEIR RELATIONS TO MAN. redations by harmless means, except at an attending expense too great to be borne by small farmers. Where large tracts are under cultivation it is feasible to employ boys to stay in the fields while there is danger from birds, to keep them off, provided boys are to be had. On some of the rice-plantations in the South men and boys are supplied with arms and ammunition and kept in the field during the migration season. They shoot to kill and to frighten, to give flocks on the ground a good send-off, and to keep those in the air from alighting. A constant fusillade is kept up for weeks. It is an expensive method, but nobody has been able to show a better one. In view of all that we know of the economic qualities of these birds, the wise course appears to be to molest them only when beyond a doubt they are in mischief. An entire flock will leave a field in as much haste, go as far, and remain away as long as half of it; so, unless there be malice to satisfy, a blank shot is as good asa full charge. The only advantage of putting a gun in a watchman’s hand is to enable him to cover more ground. ‘The birds are as afraid of him without a gun as with one, the only difference being that they are sooner aware of his presence. The chief purloiners of small fruits are cedar-birds and robins. As has already been shown in Chapter III., a large number of birds eat fruit, but the majority are satisfied with the wild varieties that grow in their accustomed haunts. None of our Northern birds feed so largely upon soft fruits as these two, at least not in spring and early summer. Cedar-birds are essentially frugivorous, though they catch many beetles and other flying insects, particularly in spring, when there is not much fruit to be had. They go in flocks, and when they come to good feeding, stay by as long it lasts. They are nearly indifferent to man, being neither wary nor familiar. High living is their main object in life. Berries in a suburban garden or on an uninhabited mountain are quite PREVENTING THE DEPREDATIONS OF BIRDS. 301 the same to them. But, though cedar-birds do not hesitate to visit populous quarters when the best fruit is there, as soon as wild lands come into competition they are ready to with- draw. The case with robins is somewhat different. They rely on man inameasure. Their line of distribution has extended very much according to his. They choose to build their nests in orchards and to seek their living on cultivated ground. On small farms, in country villages, and in city suburbs they are most abundant. Berries constitute more than half their nor- mal fare. When orchards are occupied by frugivorous birds, fruit is bound to suffer unless the ratio of fruit to birds is very large. It is a fact that most complaints against robins and cedar-birds come, not from the extensive producers, but rather from those who cultivate small gardens to supply their own tables. Early varieties of strawberries and cherries suffer most largely, for the reason that wild fruits are not yet matured. Many an anticipated treat on home-grown berries has been defeated by robins and cedar-birds. Shooting is frequently resorted to. Brooding birds are slain, foliage, fruit, and branches are punc- tured, yet the fruit is neither saved nor paid for. It is not uncommon to see cherry-trees decked with bright- colored cloths. The birds reconnoitre a little, but very shortly the gay trimmings only serve to garnish the feast. We have known a stuffed hawk placed in a tree to keep them away for a day, but no longer. The only sure way of preventing the depredations of these birds is to cover the fruit-bearing plants with netting. Of course this is practicable only in case of small quantities or rare varieties. Anysort of netting, coarse mesh or fine, will answer the purpose. Where there is plenty of land, there is no way so satisfac- tory, on the whole, as to set out other berry plants, such as the Russian mulberry, for instance, which are ornamental when in bloom, make good shade, and will be patronized by 302 BIRDS IN THEIR RELATIONS TO MAN. birds, to the relief of the garden. By this means it is possible to retain both birds and berries. Of all bird invasions none are quite so exasperating as those of the rapacious species, the owls and hawks, which not only rob us, but lacerate and kill helpless, harmless creatures which, by their dependence upon our care and bounty, have a share of our affection. The loss is vexatious ; the cruelty is maddening. Owls do relatively little harm, and there is really no excuse for permitting them to do that little, for it is only necessary to make fowls roost indoors to avoid it altogether. No such simple means can be employed to prevent the raids of hawks. When pushed by hunger, hawks have no fear of man or any of his inventions. They dash down and clutch a chicken in a village street with as much assurance as if it were in a secluded meadow. While it is apparently out of the question to keep hawks away by fear, at least of inanimate objects, it is possible to employ to our advantage the hatred or fear which other birds have for them. Kingbirds never allow a hawk to pass them in peace. There is no better insurance against hawks than a family of kingbirds located near the poultry-yard. An apple-tree in- clined to grow scraggy, if left untrimmed, is likely to prove the most profitable tree in the orchard, for it is almost sure to be selected by a kingbird for a nest-tree. A bird-house, when. tenanted by a family of purple martins, will answer the same purpose. Martins have a hatred of hawks nearly equal to that of kingbirds. A well-built martin-house, one that suits these rather exacting birds, will prove a good investment in any farm-yard. Some poultrymen keep a few guinea-fowls for the sole pur- pose of alarming hawks by their harsh clatter. Like turkeys, the days of their wild state are not so remote that they have lost their native ability to discern enemies afar off. They notice the approach of a hawk long before ordinary fowls, and PREVENTING THE DEPREDATIONS OF BIRDS. 303 raise such a din of voice that it is usually deterred from com- ing very near. Among people in general there is perhaps a greater need of education concerning hawks and owls than concerning any other group of injurious birds, or even all of them put together. We have only one owl and three or four hawks that are not more beneficial than otherwise. This being the case, we see the folly of setting a bounty on the heads of the whole family, as has been done at various times in several States. Such a bounty takes money from both pockets and throws it to the winds. If farmers knew the troublesome hawks by sight and sound, a little scouting in the spring would enable them to ascertain whether any were breeding in the neighborhood. The sharp-shinned hawk, Cooper’s hawk, and the goshawk, the three species that are most injurious, are all easily discov- ered where they have a nest or intend to build one. Except while migrating, these hawks are mainly confined to a limited area adjacent to their breeding-places, and when these places are known, a steel trap put in the nest may generally be de- pended upon to secure both birds. If one is careful to shoot the male first, a gun will accomplish the same result. When a hawk belonging to a species generally beneficial falls into bad habits, there is nothing to be done but to plan for the destruction of that particular bird by the best means available. The occasional lesser depredations of birds are generally too slight to deserve notice. Orioles take a few peas, gros- beaks and grouse nip off buds from certain trees in winter, two or three of the woodpeckers are fond of the tender inner bark of trees, and sometimes are guilty of tasting apples and oranges. None of these birds can be regulated. If by chance they become unbearable, the only thing to do is to kill them. However, as they are ordinarily useful, such a step should never be taken without full assurance that it is necessary. CHAPTER XXIV. ENCOURAGING THE PRESENCE OF BIRDS. To those who desire the presence of birds, either for the good they do or for love of them, methods for their encour- agement will be of interest. Birds-select their habitat with reference to food or nesting privileges. Enemies may drive them away. With this much in mind it is not difficult for one acquainted with bird ways to devise means for attracting them. But in the first place it will be well to introduce evidence to show that birds appreciate conveniences when they find them. W. Ward Fowler’ relates how a neighbor with only two or three acres of land induced fifty-three pairs of birds, exclusive of swallows and martins, to nest there in one month. In the heart of a city the writers know a shrubby garden, closed to cats and boys, which large numbers of birds visit on their migrations. Rare warblers, which many an observer has never seen in that region, visit that spot almost every year. That birds visit orchards, out-buildings, and door-yards in winter for such odd bits of food as they may obtain, is well known by all who live in the country. The profit that may be derived from feeding them is not so well known. Mr.E. H. Forbush? gives an account of how birds were attracted to an old neglected orchard in the town of Medford, Massachusetts. Its situation was favorable, there being a variety of wild fruit- bearing trees and shrubs, and a small piece of woodland consisting chiefly of pines near by. The orchard was in a dilapidated condition at the start, and for three years efforts in its behalf were limited to pruning the trees and protecting them from the ravages of the canker-worms and tent-cater- 1A Year with the Birds, p. 118. 2In Bulletin No. 2, Mass. Crop Reports, July, 1895. 304 Photographed from life by br. HR. W. Shafeldt. ORCHARD ORIOLE. YOUNG. ENCOURAGING THE PRESENCE OF BIRDS. 305 pillars which infested the district. These trees revived some- what under this treatment and began to bear sparingly. The fourth year nothing was done towards destroying the insect pests or in any way interfering with their increase. In the fall of this year immense numbers of the wingless females of the fall canker-worm were seen ascending the trees and de- positing their eggs. The eggs of the tent-caterpillar moth were also numerous on the twigs, giving promise of great damage to the foliage of the old orchard on the following summer. In the mean time, however, pieces of meat, bone, and suet were suspended from the trees, and chickadees, nuthatches, woodpeckers, and brown creepers made the or- chard their central station. The chickadees, which, of course, were most numerous, became so tame as frequently to alight upon the person having the experiment in charge, and occa- sionally took food from his hand. Although the food put up for the birds was eaten very freely, it was by no means their sole diet. All of the species were seen to devour quantities of canker-worm eggs, scale-lice, and various hibernating in- sects injurious to fruit-trees, and these observations were confirmed by the examinations of stomachs. They were also found to feed upon similar insect matter in the neighboring woods. As spring advanced, the female spring canker-worm moths came up from the ground to deposit their eggs on the apple- trees. Both the moths and their eggs were devoured in great numbers. As insect food increased, the birds paid less atten- tion to the meat. When the breeding season arrived the or- chard was mostly deserted by the winter visitors, to be occu- pied by the summer residents, though both chickadees and woodpeckers nested in the vicinity. Summer exhibited the results of the experiment. While other orchards in the neigh- borhood were infested by canker-worms and tent-caterpillars, this one was comparatively free from both. That the damage done here by canker-worms was far less than elsewhere must 20 306. BIRDS IN THEIR RELATIONS TO MAN. be attributed to the work of the birds that were fed through the winter. With a single exception this was the only orchard in the vicinity that produced fruit that year. Winter birds often fare very hard; and even if one has no orchard that needs them, it is an act of kindness to supply them with bits of meat or suet or nuts as may be convenient. At this season, when animal life is at its lowest ebb, it is a joy to see the sprightly little creatures about the house. They become very tame and not infrequently alight upon the hand or enter an open window for tidbits. Driven by hunger, they make forays into town, and thus it is possible for those living in villages or city suburbs to enjoy winter birds if they wish. Chickadees, nuthatches, and woodpeckers are sure to come if refuse meat or suet is tied to branches of trees, and when once baited they will come to the window-sill for supplies when none are to be had elsewhere, so there is the best possi- ble opportunity to study them. Blue-jays will come to an ear of Indian corn mounted on a stick in the orchard, and by de- grees may also be led to join the house-group. Seed-eating birds, such as juncos, tree-sparrows, and redpolls, will come to the door-yard if a bundle of ragweed, buckwheat, a few sun- flower heads, or even shallow trays of small seeds are put out. In order to furnish tempting food for summer birds there must be more elaborate preparations. At that season food is so plentiful that only the best will entice them. Even the best conditions possible will fail to bring them within such close range as is obtained with winter birds. Nevertheless, many birds will come if one will provide for them. About the only sort of food that can be offered with good effect is fruit; but of this there is such a variety both in kind and sea- son that where there is a suitable area there is no difficulty whatever in having an abundance of birds, particularly in spring and during the late summer and autumn. In the selection of ornamental shrubbery for village and suburban grounds the birds should be remembered. There ENCOURAGING THE PRESENCE OF BIRDS. 307 are many native shrubs and trees that are decorative and at the same time attractive to birds. More important than sum- mer food is a good site for a nest, and by providing nesting- places birds that care little or nothing for fruit will be attracted. It is well known that certain birds usually select a particu- lar kind of tree for their nests. For instance, goldfinches breed in maples oftener than in all other trees put together; so does the warbling vireo. Baltimore orioles prefer elms. A RETREAT FOR WINTER BIRDS. Brown thrashers select thorny shrubs. Many birds are not particular so long as they have a good cover. Between food and nest habits, he who would plant trees can select such varieties as to fill his grounds with beauty and song. Let him set a few maples. Vireos will peer and sing in them all summer long, and very often leave their pendent nests as a reminder of summer days, when the branches are bare and cold winds go moaning through them. Goldfinches are sure to come'in August. Robins and cedar-birds fre- quently reside there, and when the pine-finch comes down 808 BIRDS IN THEIR RELATIONS TO MAN. from the North on its winter visit, the buds and seeds of the maple are certain to receive a call. The elm, as has been already stated, is the favorite with the Baltimore orioles, but other birds are fond of them too. Purple finches feed upon the opening flower-buds and from their summit pour out their spring-tide of song. Crossbills and goldfinches visit them in June to feast upon their ripening seeds, and when the seeds are fallen, all sorts of seed-eaters will come to the feast. The mountain-ash is often used for an ornamental tree. Its cymes of red berries are quite as attractive to robins and cedar-birds as to us. The dense foliage and symmetrical form of red cedars render them excellent for solitary places. Spring and fall, robins, cedar-birds, purple finches, and even crows, will come for their berries. Bird-cherry and black-cherry and mul- berry trees set along the margin of a lot will bring bluebirds, thrushes, robins, and even kingbirds in great numbers, and at . the same time form a good background for smaller and more ornamental varieties. A thick clump of evergreen trees in a secluded spot will certainly be occupied at night and become a centre of radiation for matin songs, and in winter cross- bills and siskins will come for their seeds. A remote corner planted with stag-horn sumac, barberry, catbrier, and black- berry bushes, and left to itself, will become an asylum for cat- birds, brown thrashers, and many other birds which ordinarily nest in tangles. The bright yellow flowers and red berries of the barberry bush, hanging as they do in graceful sprays, are ornamental anywhere. The berries are very persistent, remaining till next year’s crop is well started, and are devoured by many birds when other food is scarce. The bay or wax- myrtle bush has an aromatic fragrance in summer, and is not unsightly in quiet corners with its winter load of pallid berries. A small plat devoted to it will flood the grounds with myrtle warblers every fall and thereby indirectly prove a scourge to insects, as these birds prefer an insect diet and turn to bay- berries only when insects fail.

Chapman has described ' an excellent bird’s-bath in use on his grounds, * Bird Lore, vol. iii. p. 74. 310 BIRDS IN THEIR RELATIONS TO MAN. and illustrated in the accompanying picture. ‘It is made of bricks and cement and in cross-section resembles the diagram on the previous page. ‘‘Boards may be used to form partitions, which should be filled with earth. The plants introduced were sagittaria, iris, yellow pond-lily, wild rice, duckweed, and water-hyacinth. The pond is filled from a hose and replenished as evaporation requires.” This bath was not only a pretty bit of adornment to the lawn, but also proved very attractive as a bathing-place for birds. In his admirable little leaflet on ‘The Birds and I,” Pro- fessor L. H. Bailey writes: ‘“‘ For some kinds of birds we can build houses. Some of the many forms which can be used are shown in the pictures. Any ingenious boy can suggest a dozen other patterns. Although birds may not appreciate architecture, it is well to make the houses neat and tasty by taking pains to have the proportions right. The floor-space in each compartment should be not less than five by six inches, and six by six or six by eight may be better. By cutting the boards in multiples of these numbers, one can easily make a house with several compartments; for there are some birds, as martins, tree-swallows, and pigeons, that like to live in families or colonies. The size of the doorway is important. It should be just large enough to admit the bird. A larger opening not only looks bad, but it exposes the inhabitants to dangers of cats and other enemies. Birds which build in houses, aside from doves and pigeons, are bluebirds, wrens, tree-swallows, martins, and sometimes the chickadee. For the wren and chickadee the opening should be an inch-and-a-half auger-hole, and for the others it should be two inches. Only one opening should be provided for each house or compartment. A perch or door-step should be provided just below each door. It is here that the birds often stop to arrange their toilets; and when the mistress is busy with domestic affairs in-doors, the male bird often sits outside PROFESSOR BAILEY’S SUGGESTIONS FOR BIRD-HOUSES. (After Cornell University Experiment Station. ) 311 312 BIRDS IN THEIR RELATIONS TO MAN. and entertains her with the latest neighborhood gossip. These houses should be placed on poles or on buildings in somewhat secluded places. Martins and tree-swallows like to build their nests twenty-five feet or more above the ground, but the other birds usually prefer an elevation less than twelve feet. Newly- made houses, and particularly newly-painted ones, do not often attract the birds.” Bird-houses should be protected from cats. If the houses are in trees, several rings of barbed wire may run around the tree spirally, near together, and held in place by staples. If the houses are on poles which the cats can climb, the same device may be used, or a horizontal shelf of tin may be fastened below the house. One of the commonest difficulties with the use of bird- houses is that they are taken possession of by English spar- rows to the exclusion of the native birds. For bluebirds at least this may sometimes be avoided by the use of the sparrow-proof houses described and figured in Bird Lore, by Mr. D. R. Geery, of Greenwich, Connecticut. ‘‘ When designed for bluebirds they should be suspended from a limb ten or twelve feet from the ground, in such a manner as to allow them to swing slightly. It may happen that the sparrows will go to these houses and even commence to build; but as soon as they find that they swing and are not firm, they will abandon them entirely. Wren-boxes should be stationary, with an opening not much larger than a twenty-five-cent piece, and placed so as to be well shaded most of the day.” Other observers have reported, however, that sparrows will occupy such swinging houses. Helpful suggestions upon this phase of the subject may also be gotten from an excellent little English book by John R. B. Masefield, entitled ‘‘ Wild Bird Protection,” and from Neltje Blanchan’s “ How to Attract the Birds.” An admirable idea has been carried out in the Manual Training Department of the Worcester, Massachusetts, schools | -PROFESSOR BAILEY’S SUGGESTIONS FOR BIRD-HOUSES. (After Cornell University Experiment Station. ) 313 314 BIRDS IN THEIR RELATIONS TO MAN. in making the construction of attractive bird-houses a regular part of the course in woodwork. Pictures of these houses are shown in the suggestive bulletin by Professor C. F. Hodge, entitled ‘Our Birds.” There is no.easier way of enticing birds in summer than by putting up boxes or similar artificial retreats for nests. Blue- birds, wrens, tree-swallows, and martins have come to be so largely dependent upon human thoughtfulness that there need be no apprehension of failure on this score. Almost anything that is hollow and has a hole for an entrance will do. A gourd or a small box made from weather-worn boards hung in a tree or put upon a pole, will satisfy the birds quite as well as more expensive domiciles. A narrow strip of board nailed along the eaves of the stable will offer a desirable nesting-site for cliff-swallows. A shelf beneath an overhanging part of a building is likely to be occupied by a pheebe’s nest. Barn- swallows will locate.on the rafters of out-buildings if given access. Birds may be further favored in the way of procuring material for their nests. In dry seasons such birds as robins, pheebes, and swallows often have to go a long way for mud which forms the framework of their nests. A peck of clay put in an old pan or box, or even spread out in the road, and kept moist by the application of a little water two or three times a day, is of great assistance to them. Orioles, kingbirds, and cedar-birds are always glad to come into the yard for yarn put out on the trees or fence for their use. Vireos will come for strips of birch-bark and sometimes for bits of newspaper; even feathers left on the ground where they may be readily seen are picked up by swallows and used for lining their nests. After one knows what birds’ nests are made of, he has only to supply suitable material,—the birds will come. Birds that employ woolly material may be in- duced to construct very gay homes by supplying them with colored worsteds. It would probably be well to cut all strings ENCOURAGING THE PRESENCE OF BIRDS. 315 into lengths of a foot or so, to avoid some of the bird tragedies which have lately been recorded. Finally, birds are encouraged in the same ratio as their enemies are discouraged. In the country, hawks, crows, jays, and squirrels are usually their worst foes. In or near town, boys and cats give most trouble. Eternal vigilance will go a long way, but it will not prevent the ravages of cats. If one wishes to keep cats from marauding on his grounds, he must surround them with a cat-proof fence; there is no other way. Such a fence may be constructed of woven wire such as is used for hen-yards. It should be not less than six feet high, and at the top there should be an excess of about two feet of the netting left to hang loosely outward nearly horizontally, to head off adventurous climbers. Entrance may be made by means of doors or gates covered with netting, made to swing outward and closed by spring hinges. Mr. William Brewster, of Cambridge, Massachusetts, has a fence of this kind around his grounds that has proved a com- plete success. Mr. Brewster informs us that failure to close a door properly admits perhaps one cat a year, but none ever scales the fence from the outside. The presence of birds near at hand gives admirable oppor- tunities for hunting with a camera, that merciful sport which is rapidly taking the place of the more cruel hunting with a gun. The improved lenses and cameras now available for this work render it a comparatively simple matter to get pic- tures of birds that shall be a joy to the possessor as well as to all beholders. APPENDIX I. THE BIRD LAW OF THE AMERICAN ORNITHOLOGISTS’ UNION. An Act for the Protection of Birds and their Nests and Eggs. Section 1.—No person shall, within the State of kill or catch or have in his or her possession, living or dead, any wild bird other than a game-bird, nor shall purchase, offer, or expose for sale any such wild bird after it has been killed or caught. No part of the plumage, skin, or body of any bird pro- tected by this section shall be sold or had in possession for sale. For the purposes of this act the following only shall be consid- ered game-birds: The Anatide, commonly known as swans, geese, brant, river- and sea-ducks; the Rallide, commonly known as rails, coots, mud-hens, and gallinules; the Limicole, com- monly known as shore-birds, plover, surf-birds, snipe, woodcock, sand-pipers, tattlers, and curlews; the Galline, commonly known as wild turkeys, grouse, prairie-chickens, pheasants, partridges, and quails. Sec. 2.—No person shall, within the State of take or needlessly destroy the nest or the eggs of any wild bird nor shall have such nest or the eggs in his or her possession. Src. 3.—Any person who violates any of the provisions of this act shall be guilty of a misdemeanor, and shall be liable to a fine of five dollars for each offence, and an additional fine of five dollars for each bird, living or dead, or part of bird, or nest and eggs possessed in violation of this act, or to imprison- ment for ten days, or both, at the discretion of the court. Src. 4.—Sections 1, 2, and 3 of this act shall not apply to any person holding a certificate giving the right to take birds and their nests and eggs for scientific purposes, as provided for in Section 5 of this act. Sec. 5.—Certificates may be granted by [here follow the names of the persons, if any, duly authorized by this act to grant such certificates], or by any incorporated society of natural history 317 318 APPENDIX I. in the State, through such persons or officers as said society may designate, to any properly accredited person of the age of fifteen years or upward, permitting the holder thereof to collect birds, their nests or eggs, for strictly scientific purposes only. In order to obtain such certificate the applicant for the same must present to the person or persons having the power to grant said certifi- cate written testimonials from two well-known. scientific men, certifying to the good character and fitness of said applicant to be intrusted with such privilege; must pay to said persons or officers one dollar to defray the necessary expenses attending the granting of such certificates; and must file with said persons or officers a properly executed bond in the sum of two hundred dollars, signed by two responsible citizens of the State as sure- ties. This bond shall be forfeited to the State and the certificate become void upon proof that the holder of such a certificate has killed any bird, or taken the nest or eggs of any bird, for other than the purposes named in Sections 4 and 5 of this act, and shall be further subject for each such offence to the penalties provided therefor in Section 3 of this act. Sec. 6.—The certificates authorized hy this act shall be in force for one year only from the date of their issue, and shall not be transferable. Sec. 7.—The English or European house-sparrow (Passer domesticus) is not included among the birds protected by this act. Sc. 8.—All acts or parts of acts heretofore passed, inconsist- ent with or contrary to the provisions of this act, are hereby repealed. Sec. 9.—This act shall take effect upon its passage REMARKS. The accompanying law is calculated to protect our birds as effectually as any legislation can, and it is desirable, if possible, to obtain its passage as it stands. It is, however, a well-known fact that in many of our States the ‘act would not receive favor- able consideration unless modified in several particulars. We offer the following suggestions regarding revision when it is unavoidable : APPENDIX I. 319 1. Game-Birds.—In many States doves are universally classed as game-birds, and where the game laws cover their protection during a closed season they may be so classed in Section 1 if necessary. Reed-birds and blackbirds may have to be treated in the same way in several States. Robins, flickers, and meadow-larks, how- ever, should not be permitted to be classed as game. 2. Cage Birds.—There is nothing in the law to prevent the keeping of foreign cage birds, as canaries, etc. To keep native birds alive for study, etc., a certificate must be secured as per Section 5. This is necessary to prevent traftic in live birds. 3. Other birds which may have to be excluded from pro- tection : Hawks and Owls.—The prejudice against these birds is very strong, while the argument in their favor is well known and conclusive. They should be protected if possible. If nothing better can be done, effect a compromise by excluding Cooper’s hawk, goshawk, sharp-shinned hawk, and great horned owl, and protect the rest. Crows may have to be denied protection; there is about as much evidence for as against them, however. Shrikes, herons, gulls, and terns should by all means be protected. +. Where it is absolutely necessary to exclude any birds from protection they may be added to Section 7, so as not to alter the main text. 5. On no account omit Sections 4, 5, and 6, as has been done in some of the present laws. With the restrictions placed upon holders of certificates there is no danger of improper persons obtaining them. A small num- ber of birds are required for scientific purposes, and provision should be made for obtaining them as much as for shooting game- birds. The fee should be abolished, if possible, and should on no account be more than one dollar. The age limit should, more- over, not be raised above fifteen years. APPENDIX II. THE LACEY BIRD LAW. An Act to enlarge the Powers of the Department of Agriculture, prohibit the Transportation by Interstate Commerce of Game killed in Violation of Local Laws, and for other Purposes. Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the duties and powers of the Department of Agriculture are hereby enlarged so as to include the preservation, distribution, intro- duction, and restoration of game-birds and other wild birds. The Secretary of Agriculture is hereby authorized to adopt such measures as may be necessary to carry out the purposes of this act and to purchase such game-birds and other wild birds as may be required therefor, subject, however, to the laws of the various States and Territories. The object and purpose of this act is to aid in the restoration of such birds in those parts of the United States adapted thereto where the same have become scarce or extinct, and also to regulate the introduction of Ameri- can or foreign birds or animals in localities where they have not heretofore existed. The Secretary of Agriculture shall from time to time collect and publish useful information as to the propagation, uses, and preservation of such birds.

SOME FUNDAMENTAL PRINCIPLES OF BIRD LAWS. BY T. S. PALMER. ADEQUATE laws necessarily form the foundation of effective bird protection. But it is not enough merely to enact laws: they must be enforced and doubtful points must be settled by the courts. The bird laws of the United States, usually called game laws, are of two kinds (a) State or local laws and (b) Federal laws. State laws prescribe the kinds of birds which may or may not be killed, the time and manner in which they may be taken, and the purpose for which they may be captured. Thus the Illinois game law defines game-birds and prohibits the killing of other birds at any time. In providing for game it fixes a definite season for shooting quail and ducks, but forbids the kill- ing of ducks at any season from a sail-boat, with a swivel gun, or after sunset; furthermore it declares that it shall be unlawful to capture quail in the State for sale or ship to other States ex- cept under license. In all these matters the State is supreme and violations of its laws are tried in the State courts. The Federal law, commonly known as the Lacey Act, or the Act of May 25, 1900, deals merely with the shipment of birds from one State to another and the importation of birds from foreign countries. It is general in its provisions and does not mention special birds, but, nevertheless, supplements the State laws very effectually. Thus if a State prohibits the killing of any particular bird, the shipment of the bird out of that State is an offence under the Federal law, and the shipper, carrier, and consignee, each or all, may be prosecuted in the United States courts. Some of the principles on which these laws are based may be stated very simply as follows: 323 324 APPENDIX III. (a) STATE LAWS. 1. All wild birds are the property of the State, hence: 2. Killing birds is a privilege, not a right. 3. State ownership of birds carries with it the right to impose restrictions, hence: 4, Birds may be captured, possessed, transported, bought, or sold only under such conditions as the State prescribes. 5. Land-owners have no more right to kill birds out of sea- son than other persons, unless the law specifically grants this privilege. -(b) FEDERAL LAW. 6. Birds are protected by the Federal law only when shipped from or into a State which protects them by a local law. %. Birds killed or shipped contrary to law in any State cannot lawfully be transported to other States. 8. Birds brought into a State become subject to its laws in the same manner and to the same extent as birds produced-in that State. 9. Packages of birds shipped from one State to another musi be marked so as to show the name of the shipper and the nature of the contents. 10. Foreign birds can be imported into the United States only under permit from the United States Department of Agriculture, and birds declared injurious by the Secretary of Agriculture can- not be imported into the United States or shipped from one State to another. Simple as all these propositions may seem, they have been the cause of much discussion. Most of them, however, have been passed upon by the higher courts and are no longer open to question. The right of the crown to all wild game was estab- lished in England years ago, and the State ownership of game now clearly stated in the laws of Colorado, Illinois, Michigan, Minnesota, Texas, and Wisconsin is an inheritance from the English common law. The Supreme Court of the United States has upheld this claim as well as the right of the State to prohibit killing game for sale (125 U. S., 465) or export (Geer vs. Connecticut, 161 U. S., 519). Possession of birds out of season was long regarded ‘merely APPENDIX III. 325 as evidence of illegal killing, but is now made an offence punish- able by fine in several States. The right of a State to make laws regarding birds imported from other States has been vigor- ously contested and has been variously decided by the courts, but the question has now been practically set at rest by the passage of the Lacey Act. Some States have hesitated to en- croach upon the rights of the individual, as shown by the excep- tion in favor of land-owners in the section of the Delaware law relating to insectivorous birds, and also by the provisions in the laws of Illinois, Kansas, Kentucky, Louisiana, Ohio, and South Carolina which permit a person to kill birds found destroying fruit on his own premises. On the other hand, Massachusetts declares that game artificially reared shall be the exclusive prop- erty of the person raising it, but forbids the owner to sell it for food during close seasons. Illinois exacts a ten-dollar hunting license from non-residents, even though they lease or own a game preserve within the State, and Wyoming, in the famous “Race Horse case,” carried up to the Supreme Court in 1896, has successfully maintained her right to compel Indians to obey her game laws (163 U. 8., 504). During the last fifty years the sentiment in favor of bird pro- tection has developed rapidly. Many laws have been enacted, amended, and sustained by the courts. That these laws are still imperfect is partly the result of carelessness and partly of strong opposition due to ignorance or selfishness. Our game laws, un- like those of Europe, are maintained for the good of the people as a whole, not for the benefit of any one class, and their enforce- ment depends very largely on a general appreciation of the prin- ciples upon which they are based.—Bird Lore, vol. iii., pages 79-81. APPENDIX IV. A PARTIAL BIBLIOGRAPHY OF THE ECONOMIC RELATIONS OF NORTH AMERICAN BIRDS. BY CLARENCE M. WEED. Tu importance of birds as checks upon the undue increase of noxious insects has long been recognized by observing men scat- tered here and there throughout the United States. Buta general appreciation of the value of these feathered allies is of com- paratively recent development, and in some regions they are still unappreciated. The literature which has led to a wider knowledge of the value of birds has been scattered through many publications, much of which is inaccessible to the general reader, and some of it diffi- cult to obtain even by the specialist. In the following pages I have attempted to bring together a bibliographic list of the more important articles treating of the economic relations of our birds. In compiling it I have had the help of Messrs. A. F. Conradi, W. F. Fiske, and R. A. Cushman, while assistants in the ento- mological department of this station. For a number of citations of articles in Forest and Stream I am indebted to the pages of The Auk, while a few others have been gleaned from various other sources. It has been impracticable to include citations of the great mass of literature treating specifically of game-birds, or their acclimation and domestication, as well as of the thousands of references to the English sparrow, and of the many general bird books of recent years. 1854.

Brief notes on distribution and habits of the two birds, fol- lowed by statements of their food as indicated by the examina- tions of a large number of stomachs. Almost three-fourths of the food of the meadow lark was found to consist of insects, and of these a very large percentage were grasshoppers and crickets. The accusation of pulling sprouting grain and feeding upon grain generally appears not without basis, but the damage done in this manner is more than counterbalanced by the num- bers of insects eaten. The food of the oriole was found to con- sist almost exclusively of insects, and these to a large extent of noxious species. No question can be raised as to the value of this bird as an insect destroyer. 23 354 1896. 1896. 1896. 1896. 1896. 1896. 1896. APPENDIX IV. Butter, A. W.

United States Department of Agriculture, Yearbook, 1896, pages 197-206. General remarks on habits and distribution of blue jay, fol- lowed by an account of examination of two hundred and ninety- two stomachs. The bulk ot the food was found to be of vegetable origin, namely mast, the amount of fruit and cereals being small. In certain seasons of the year many insects were eaten, few of them beneficial. But a very small percentage of the whole consisted of vertebrate remains, thus giving little support to the reports of damage done by eating small birds, nor were birds’ eggs eaten to any extent. The relative proportions of the various foods varied remarkably from season to season. Brat, F. E. L. Some Common Birds in their Relation to Agriculture. United States Department of Agricul- ture, Farmer’s Bulletin, No. 54. ‘ A short popular discussion of the food habits of a number of birds of more or less importance to the farmer.

General notes on North American cuckoos, followed by an account of the examination of one hundred and fifty-five stom- achs of both species. Food was found to consist almost exclu- sively of animal matter. Nearly fifty per cent. of the whole was composed of caterpillars, of which, contrary to the usual habits of birds, hairy species were in the majority. The percentage of Orthoptera ranged from three per cent. in May to forty-three in July, mostly arboreal forms, and there were from five to six and one-half per cent. of miscellaneous insects, beetles and bugs respectively. No particular support was found to the accusation that they are in the habit of sucking eggs of other birds. BiancHan, Nexrsz. Birds that Hunt and are Hunted. New York: Doubleday & McClure Company.

General notes on North American shrikes, followed by an account of the examination of one hundred and fifty-five stom- achs of both species. So far as could be determined from the stomachs of sixty-seven butcher-birds the food closely resembled that of the sparrow-hawk. About twenty-six per cent. of the food consisted of mice, thirty-four per cent. of small birds, in- cluding many English sparrows, consisting almost wholly of seed-eating species, and the remainder of insects, mostly grass- hoppers. The food of the loggerhead differs in the much smaller percentage of mice and birds, about twenty-four per cent. The insects eaten consist largely of Orthoptera, and in the spring of beetles, many of them predaceous species. Both the butcher-bird and loggerhead eat, to some extent, caterpillars.
