CONSERVATION OF OUR WILD BIRDS CONSERVATION OF OUR WILD BIRDS CONSERVATION OF OUR WILD BIRDS METHODS OF ATTRACTING AND INCREASING THE NUMBERS OF USEFUL BIRDS AND THE ESTABLISHMENT OF SANCTUARIES BY BRADFORD A. SCUDDER SECRETARY OF THE MASSACHUSETTS nSH &. GAME PROTECTIVE ASSOCIATION ISSUED BY THE MASSACHUSETTS FISH AND GAME PROTECTIVE ASSOCIATION 748 TREMONT BUILDING BOSTON V^^^^^^ 1 .S3 INTRODUCTION VERYWHERE throughout this broad land of ours there exists a wholesome de- sire to protect the wild life about us. We of this twentieth century are living in an age when both societies and individuals are zealously striving, not only to inspire a love for this wild life, but also to instruct the people at large regarding how it may be wisely conserved. Love for the out-of-doors is strong in most of us and the call to the country is insistent. Each year the throng increases of those who respond to this summons, — many to reside there permanently, others as sojourners only during the delightful months of the year, and the charms of a country life are doubly enhanced by the presence of the wild creatures about us. The wild life, especially the birds, contribute largely to both our welfare and our happiness. While engaged in their important work of ridding the country of injurious insect pests and the seeds of noxious weeds, they at the same time gratify our aesthetic tastes by their cheery songs, bright colors, and vivacious movements. There is also the additional charm of being able to watch the evolution of their home-building, from the gathering of the first nesting material until the young spread their wings and fly away. Unfortunately many of those who delight in the charms of the country have been denied the opportunity of learn- ing much about the habits of birds, — what species will nest in bird-houses, where to properly place these houses, or how to care for the birds that visit us in the bleak [7] weather of winter and come about our homes searching for food. Hosts of birds may be attracted about our country homes at all seasons of the year by offering food, shelter, and suit- able lodgings, and the author in following the precepts of the Massachusetts Fish and Game Protective Association, has endeavored to set forth in a manner both clear and comprehensive, methods by which this may be accom- plished. In this important work of protecting and conserving our wild life we are confronted with a situation that de- mands instant and careful consideration. The author refers to the antagonistic points of view held by the bird pro- tectionist and the sportsman. The former adheres to the theory that the shooting of all birds and quadrupeds for mere sport should be absolutely abolished, while the latter argues that game birds and quadrupeds exist for the pur- pose of providing a source of legitimate recreation. We do not wish to criticise the exponents of these doctrines, — each has a right to his own beliefs. Therefore let us strive to create a spirit of goodwill and cooperation, such as will inspire both parties to devote their energies unceas- ingly to the cause of wild life protection and propagation. Our game birds afford recreation to many that delight in shooting, — a legitimate pastime when tempered with moderation, and one to be encouraged as an incentive to become better acquainted with nature, and to render the young mind keen by training the powers of observation. Savage man however, hunted not for the mere sport of the chase, but to supply himself with the necessities of [8] life. So, all statements to the contrary notwithstanding, do not try to excuse your own present sporting propensity, on the ground that it is a portion of the inheritance be- queathed you by an ancestor, who armed with a flint- tipped spear followed the pre-historic mammals. Our wild life of the present day is in numbers but a fragment of what our country contained a quarter-century ago. That vandal, commercialism, the destroyer of our natural resources, played havoc, not only with our game birds and quadrupeds, but also with our birds that con- tribute so largely to the welfare of the country in an eco- nomic way. Now that the market-hunter and the pur- veyor of plumages of wild birds are no longer allowed to ply their nefarious trade, our wild life may hope to estab- lish itself in its former abundance, but we must all "put our shoulders to the wheel," and help repair *'the years that the locusts have eaten." By the establishing of refuges the birdlover and the sportsman may meet on common ground and be of mu- tual benefit. In every city and town there should be established a permanent sanctuary, — the most successful method of perpetuating our useful and interesting forms of wild life. In conserving our game birds and quadrupeds by means of protected areas, we at the same time aid in increasing the numbers of insectivorous birds, so that those who establish refuges primarily for game, become indi- rectly public benefactors. Artificial propagation of certain species of our native game birds is yet in its infancy, is doubtful of success, and too costly Ih operation to be attempted by those possessing [9] only moderate means. However if denied the possibilities of a game-farm, we may at least establish sanctuaries and increase the natural supply of game, not only by protective measures, but also by creating a sincere public sentiment for this method of game conservation. Competent admin- istration, persistent and systematic feeding and housing of the birds and rigorous enforcement of the laws, are all necessary to bring success to this enterprise. The author wishes to thank not only the members of the Executive Committee, but also many other members of the Massachusetts Fish and Game Protective Associa- tion, who by their loyal and enthusiastic support have made the publication of this book a success. Thanks are due Mr. Edward Howe Forbush, for his kindly interest shown, both by reading the proof, and in making many valuable suggestions. Our former President of this Associ- ation, Mr. William Brewster, deserves many thanks for much excellent advice given relative to bird nesting- boxes, gleaned from his experience of many years in at- tracting birds. It was for the purpose of aiding those who are interested in conserving the wild life about us that this little book was prepared, and it is the sincere hope of the author that it will be a stimulus to whoever reads its pages to join the ever-increasing ranks of those who stand for the rational protection of our WILD BIRDS.

All of these thus enumerated are found generally throughout our three Southern New England States, and when offered pro- tection will nest on our farms, often in such proximity to our houses that their home-building and domestic cares may be ob- served from the luxury of an arm-chair on the veranda, or from a convenient window. Birds of different species vary greatly in their choice of a location for a nesting-site, and it is from our knowledge of the peculiar nesting-habit of each species that we are able to anticipate their desires and prepare a congenial environment. Some birds nest on the ground, or in tussocks of grass ; some in low bushes and thick shrubbery; others among the branches of our orchard and shade trees ; some few species excavate holes in the decayed trunks, or branches of trees; and some species not able to excavate holes for themselves, will occupy these vacated apartments, and also the nesting-boxes prepared by man. Although we may not solve the secret of the Bluebirds ' pref- erence for the nesting-box, let us welcome the little home-seekers by offering an apartment to their liking. In many sections now over-run by that exotic pest, the European House Sparrow, and where nesting-boxes intended for the use of our native birds would be immediately tenanted by this unwelcome guest, birds of other nesting-habits may be attracted by the planting of thick shrubbery and coniferous trees. Therefore the birds in this subjoined list have been grouped in accordance with their nesting-habits. [13] BIRDS THAT NATURALLY NEST IN CAVITIES IN TREES — FOR THESE WE SHOULD PROVIDE NESTING-BOXES NEARLY all of the various species of birds that have recip- rocated the kindness of their human friends by accepting the nesting-boxes prepared for them, originally nested either in the abandoned homes of the woodpecker architects, or in cavities in trees formed from the combined effects of decay and the action of the elements. In either instance, the bottom of these cavities is always padded with a soft layer of particles of wood, — chips of the woodpecker artisan, or a deposit of decayed wood. All members of the wood- pecker family lay their eggs upon this layer of chips, which slightly hollowed forms a nest, no other material being used. In all nesting-boxes this natural lining of the bottom should be sup- plied, using for the purpose coarse sawdust, or ground cork, to the depth of two inches. This detail is most essential, and should not be overlooked. Woodpeckers will not occupy a nesting-box that lacks this floor covering, — the eggs would roll about on the bare floor, and prevent the parent bird from prop- erly covering them during the period of incubation. It is also the opinion of the author, that birds other than woodpeckers, species that use various materials for the construction of a nest, are more readily induced to occupy a nesting-box having this layer of sawdust or cork, than one in which it is lacking. A nesting-box, with the correct inside dimensions, and proper size of entrance for each species is given in the appended list. The mechanical construction and the placing of these nesting- boxes in position will be fully described in the chapter entitled, * * Nesting-boxes. * ' Bluebird: Nesting-box should have the following inside dimensions, — floor, 5 by 5 inches; depth, 10 inches; entrance, 1^ inches in diam- eter, with its lower edge 7 inches above the floor. It may be mounted upon a pole; fastened to the side of a barn or other farm building; or to the trunk of a tree standing in the open, and at a height of from 8 to 15 feet above the ground, wherever placed. [14] Tree Swallow I Nesting-box should have the following inside dimen- sions, — floor, 5 by 5 inches; depth, 7 inches; entrance, li^ inches in diameter, with its lower edge 4 inches above the floor. It may be mounted upon a pole, and the pole may then be screwed or bolted to a post in the fence inclosing the garden, orchard, or mowing land. When fastened to the trunk of a tree, be sure that one is chosen whose branches are high enough above the nesting-box to allow the birds free- dom of access to their home, after the foliage has fully matured. The nesting-box should be placed at a height of from 8 to 15 feet above the ground. Chickadee: Nesting-box should have the following inside dimensions, — floor, 4 by 4 inches; depth, 10 inches; entrance, 1^ inches in diameter, with its lower edge 7 inches above the floor. It should be placed at a height of from 6 to 12 feet above the ground, and may be mounted on a pole placed in the orchard, or open woods, or fastened to the trunk of a tree. All nesting-boxes for the Chickadee should be situated in open spots, and not in the dense forest. Possibly a nesting-box painted a dull white, simulating the color of a gray birch stub, would be more readily occupied by the Chickadee, than one stained a shade of brown or olive green. This is a suggestion of the author, and might be worth trying, from the fact that the Chickadee when excavating its home in a dead tree prefers the gray birch, the decayed wood of which is easily removed by the tiny builder. White-breasted Nuthatch : Nesting-box should have the following inside dimensions, — floor, 4 by 4 inches; depth, 10 inches; entrance, ly^ inches in diameter, with its lower edge 7 inches above the floor. It should be placed at a height of from 10 to 20 feet from the ground, on the trunk of a tree in open woods or in the orchard. House Wren: Nesting-box should have the following inside dimen- sions, — floor, 4 by 4 inches; depth, 8 inches; entrance, 1 inch in di- ameter, with its lower edge 6 inches above the floor. It may be fastened to the side of an outbuilding; to a tree in the orchard; or, mounted on a pole. In any of these situations, the height above the ground should be from 6 to 10 feet. Flicker: Nesting-box should have the following Inside dimensions, — floor, 6 by 6 inches; depth, 18 inches; entrance, ZVz inches in diam- eter, with its lower edge 14 inches above the floor. It should be fastened to a tree standing in the open, or a pole and at a height of from 8 to 20 feet above the ground. Trees bordering country highways, or near the edges of open fields should be selected for this purpose. Red-headed Woodpecker: Nesting-box should have the following inside dimensions, — floor, 6 by 6 inches; depth, 16 inches; entrance, 2 inches in diameter, with its lower edge 12 inches above the floor. It may be fastened to the trunk of a tree standing in the open, at a height of from 15 to 20 feet above the ground. [IS] Screech Owl: Nesting-box should have the following inside dimen- sions, — floor, 8 by 8 inches; depth, 18 inches; entrance, 3 inches in diameter, with its lower edge 12 inches above the floor. It should be placed at a height of from 10 to 25 feet above the ground, on the trunk of a tree among both pine and hardwood groves of fairly open growth, or fastened to one of the large branches of an apple tree in an ancient orchard. Sparrow Hawk: Nesting-box should have the following inside dimen- sions, — floor, 8 by 8 inches; depth, 18 inches; entrance, 3 inches in diameter, with its lower edge 12 inches above the floor. It should be fastened to the trunk of a tree standing in the open country, or along the borders of a highway, at a height of from ten to twenty feet. Wood Duck: Nesting-box should have the following inside dimensions, — floor, 12 by 12 inches; depth, 24 inches; entrance, 6 inches in diam- eter, with its lower edge 16 inches above the floor. Suitable natural nesting-sites for the Wood Duck do not occur in abundance, so that by placing nesting-boxes on the trunksof large trees withina short distance of a pond or stream, and at a height of from 8 to 20 feet above the ground, we may induce one or more pairs of these beautiful waterfowl to stay in our neighborhood, and raise a brood of young. Crested Flycatcher: Nesting-box should have the following inside dimensions, — floor, 6 by 6 inches; depth, 12 inches; entrance, 2 inches in diameter, with its lower edge 8 inches above the floor. It should be fastened on the trunk of an apple tree, or a hardwood tree standing in the open woods, about 15 feet from the ground. Downy Woodpecker: Nesting-box should have the following inside dimensions, — floor, 4 by 4 inches; depth, 12 inches; entrance, 1^4 inches in diameter, with its lower edge 8 inches above the floor. This should be fastened to the trunk, or a large perpendicular branch of an apple tree, or to a hardwood tree standing in the open forest, at a height of 15 feet. The Downy Woodpecker rarely raises a brood of young in a nesting-box, but frequently uses it as a winter sleeping apart- ment. However, by persisting in offering this species a suitable nesting- box of the above dimensions, we may eventually be rewarded by its being accepted. Hairy Woodpecker: Nesting-box should have the following inside dimensions, — floor, 6 by 6 inches; depth, 15 inches; entrance, iVz inches in diameter, with its lower edge 12 inches above the floor. This species is more of a woodland bird, than others of its family, and seldom nests in close proximity to a dwelling. Nesting-box should be fastened to the trunk of a hardwood tree in fairly open woods, and placed at a height of from 10 to 20 feet above the ground. Like its cousin, the Downy, this Woodpecker does not favor ready-made apartments, — but let us persist in our efforts to secure this bird as a tenant. [16] BIRDS THAT NEST AMONG THE BRANCHES OF ORCHARD AND SHADE TREES Robin: Nests commonly in trees of various species both broad-leaved, and coniferous, and frequently on the cornices of buildings. Kingbird : Nests among the branches of apple trees, seeming to prefer this tree to that of many other species. A pair of Kingbirds near the house are a safe-guard from the depredations of both Hawks and Crows. Scarlet Tanager : This species is also a lover of the orchard, and fre- quently nests among the branches of the apple tree. Redstart : Nest is placed in the fork of branch of maple and oak trees, in rather swampy localities, and in small white birches. Black-throated Green Warbler: Nests among the branches of the white pine, groves of which it frequents during the breeding season, and in small upland cedars. Pine Warbler : Nests and spends the breeding season among the pitch- pines, but when these trees are wanting, shares the groves of white pine with its cousin, the Black-throated Green Warbler. Yellow-throated Vireo: Nest of this species is very often suspended from a fork of the trailing branches of the elm tree. Red-eyed Vireo: The purse-shaped nest of this species is suspended from the small branches of maples, birches, and other broad-leaved trees. Cedar Bird: Nest is usually placed in the fork of a small branch of an apple or other orchard tree, and sometimes in the fork of a sapling growing in open meadow land. This bird is not an early nester, and does not commence to build until about the first of July. American Goldfinch : This species delays its nest-building until July, when it constructs a nest in the fork of one of the small branches of both apple and maple trees. Purple Finch: Nest is built among the branches of cedars, firs, and other coniferous trees. Crow Blackbird: The bulky nest of this species is built among the branches of white pine and other coniferous trees. Sometimes among bushes near water holes. Baltimore Oriole: The elm trees of our New England towns are the favorite nesting sites of this bird, from the drooping branches of which its pendulous nest is hung. Blue Jay: Nests among the branches of both coniferous and broad- leaved trees. In spite of its handsome attire, this species should not be encouraged to nest in numbers, for it destroys many eggs and young of our useful birds. Least Flycatcher: Nest is placed in the fork of a branch of an apple tree, more frequently than in that of a tree of other species. [17] Wood Pewee: Nest is usually placed in a fork of the large branches of an oak tree, and sometimes saddled on a large limb. The Wood Pewee prefers open woods of hardwood growth, free from underbrush and where the oaks predominate. The nest is an exquisite piece of work- manship, and the outside is usually studded with lichens. Ruby-throated Hummingbird: Nest is usually saddled on the dead limb of a hardwood tree, sometimes in the forest,, often in the apple orchard. It is one of the most beautiful bits of bird architecture, and simulates a knot or excrescence on a branch so closely, that the observer would pass it by unnoticed, did not the bird by angry buzzing about, betray her secret. BIRDS THAT NEST IN BUSHES AND THICK SHRUBBERY Wood Thrush: While this species is more or less of a woodland bird, it frequently appears about country estates possessing an abundance of shrubbery, particularly that bordering a small stream or artificial pond. Among this shrubbery, or in the fork of a small sapling in moist woods, the nest is built. Catbird: The nest of this species is often built in a thick clump of shrubbery near the house, such as lilac bushes, azaleas, and syringas. Clumps of high bush blueberries, and other shrubs of dense growth are also favorite nesting sites of this bird, especially about the borders of wet meadows and sluggish brooks. Brown Thrasher: This species is not as fond of nesting near our homes as is its cousin the Catbird, preferring to build its nest among the thick clumps of scrubby growth of huckleberry bushes, scrub oaks and other dense cover, of wild pasture land, both upland and swamp. After the young are hatched the parent birds come about our gardens and lawns searching for insect food for the young birds, and to indulge in the pleasures of the bird bath. Chestnut-sided Warbler: The nest of this species is placed in the fork of a small hardwood sapling. Young sprout growth of birches, and maples being frequently chosen for this purpose, as well as hazelnut, huckle- berry, and other small bushes in swampy meadows. Yellow Warbler: The nest of this species is placed in the fork of a small low-growing tree or bush of various hardwood species near the borders of swampy meadows, and sometimes midst the shrubbery near our homes. Field Sparrow: Nests in low growth of bushy uplands and fields, and occasionally the nest is placed upon the ground. Chipping Sparrow: Nest of this species is built not only in clumps of shrubbery, but also in apple trees, cedars and firs. [18] BIRDS THAT NEST UPON THE GROUND OR IN TUSSOCKS OF GRASS Ovenbird: Both this bird and the following species construct an arched nest on the ground, often beneath the protecting cover of a small pile of brush or fallen branch, in moist woods of oaks and maples. Frequently the nest is placed close by the edge of a woodland path. Black and White Warbler: As mentioned above the Black and White Warbler nests upon the ground in much the same manner as the Ovenbird. The author has found several nests of this bird that were placed under the projecting edge of a leaf-strewn depression in the oak woods, where at some former time large boulders had been removed. Song Sparrow: The nest of this species is frequently placed in the grassy overhanging bank of a brook, sometimes in a tussock of coarse grass, and occasionally in a low-growing bush. Vesper Sparrow: This species builds its nest upon the ground in upland pastures. Red-winged Blackbird: Tussocks of coarse grass, sedge and clumps of cat's-tail are all favorite nesting sites of this bird in marshes and swampy meadows. Button-ball bushes about the borders of ponds and streams are also chosen as nesting places by this species. Meadow Lark: The nest of the Meadow Lark is placed upon the ground among the tall grasses of the hayfield that form an arch over it. During the operations of mowing, care should be taken to prevent the destruction of the nest by scythe or mower knives, by having your workmen locate the nests, before the operations of the hay harvest are under way. The Meadow Lark is of inestimable value to the farmer as a destroyer of insects injurious to both hay and grain crops, and strong efforts should be made to increase the numbers of this species. Bobolink: The cheery Bobolink nests upon the ground in the midst of the hayfield where the nest is concealed beneath a tussock or clump of grass. This bird is another valuable friend of the farmer and the same care should be used in avoiding destruction of its nest during the haying- time, as with that of the Meadow Lark, Bob- White: While the whistle of the Quail comes up from the field, the wife of the merry piper is quietly brooding her eggs, along the borders of the grain field or mowing land, where she has placed her nest, — so kind farmer have a care when the hay or grain crop is about to be harvested. Other places are also chosen as a nesting site by this bird, — a clump of low-growing huckleberry or bayberry bushes, the edge of a brush-pile, or the protecting lower rail of the old Virginia fence, still found on some farms. [19] Ring-necked Pheasant: This bird has become very abundant in certain sections in Massachusetts, and having been given a long season of pro- tection, comes about our estates and nests frequently in close proximity to our homes. The nest is placed upon the ground, where it is well concealed among the thick grasses or clumps of bayberry bushes and trailing blackberry vines. Ruffed Grouse: Nests on the ground in open hardwood growth, and the nest is sometimes placed beneath a fallen tree-top, or, the edge of a pile of brush. Spotted Sandpiper : Many nests of this little sandpiper are constructed in the strawberry beds on our farms, where the bird arranges a nest of the hay or straw used as a winter protection to the plants, and deposits her eggs. Woodcock: Nests on the ground in swampy or moist woodlands. Both parents and young visit the gardens at night in search of earthworms and grubs, and cornfields of the farmer are also favorite feeding grounds. BIRDS THAT NEST IN BUILDINGS OR ON THE BEAMS BENEATH BRIDGES Barn Swallow : Nests on the beams and rafters in barns, provided there is an entrance and exit continually open. The passing of our old-fash- ioned New England barn with its wide open doors and windows in roof, is the cause of the disappearance of this beautiful bird from certain localities where it was formerly abundant. Cuff or Eave Swallow: This species is of sociable disposition, and nests in colonies, the bottle-shaped nests of mud being attached beneath the eaves or cornices of country barns and outbuildings. Chimney Swift: Nests commonly throughout Southern New England wherever it can find an unused chimney. It is a good plan to watch these birds and discover which particular chimney they have chosen for nesting quarters, and thus avoid destroying both nest and young by a temporary blaze in the fireplace during the months of May, June and July. Phoebe Flycatcher: Nests on the beams and top of wall beneath barns, on the timbers beneath bridges, and often on the top rail or cornice of the veranda of the house. [20] NESTING BOXES SOMETIME in the long ago an American Indian made the astonishing discovery that birds of certain species could be induced to occupy homes fashioned for them by human hands, and promptly swung aloft from the tips of his lodge-poles, cala- bashes or gourds, the dried shells of which, with entrances prop- erly cut, made ideal nesting-boxes. In many sections of the South, the calabash is grown in large quantities by the planters, and is still used as a nesting-box for Bluebirds, Purple Martins, and Wrens of several species, with most successful results. After the calabash has ripened and the shell has become hardened, a cir- cular opening of a size to admit the particular species of bird for which it is intended, is cut in the side of the calabash, at a point where its diameter is the greatest. The seeds and dried meat are then extracted by means of a piece of wire bent into a hook. Holes are made in the neck, through which a piece of stout tarred marline or other cord is passed, also two small holes, two inches apart, are made in the back, opposite the entrance, through which another cord is passed. The top cord is used for suspending the gourd from a branch, and the lower one is to prevent the gourd from swaying too much in a stiff breeze. Two or three quarter-inch holes bored in the bottom will serve for drainage, — the shape of the calabash being such that more or less water runs inside during rain storms. Calabashes have been used with considerable success as nesting-boxes in one or more towns in New York State; but for New England and other sections of the country in the same latitude, a nesting-box constructed of boards will withstand the wear and tear of the elements far better, as the calabash is rather fragile, and often lasts but one season. In the South their saving grace is minimum cost and ease of production in quantities. Nesting-boxes have run the gamut, from tomato cans to elabo- rate affairs, with roofs of burnished copper, and the manufacturer of bird houses has entered the field with his wares. Many manu- factured commodities that are displayed in the shops come from over seas, and the first nesting-boxes constructed on scientific lines, of- fered for sale in this country, bore the mark "Made in Germany.'* [21] ( B
