We have seen a boisterous oriole lead his lady to a banana leaf and do his best to coax her into immediate acceptance of the location. It is not until the following day that we notice the first swinging threads. And it is the same with many other birds which nest near the house. Perhaps the linnet, or house-finch, is the most persistent in choosing a nest site. He is sometimes seen at the business late in the fall and early winter, turning about in corners and nest-boxes, chattering to his mate, and "making himself so silly." His mate, of more sense, looks on and lets him talk, seeming to smile at his foolishness. Doesn't he know, at his age, that she will be on hand at the proper time?
As a rule, it is the mother bird who does all the nest-work. We have seen her closely followed by the male, in the case of the linnet and many of the other finches; the song-sparrow and chippie and towhee and mocker and oriole each keeps at the side of his dear companion and follows her on the wing, singing, while her mouth is full of grass or other stuff. When she alights at the threshold of her nursery he alights too, on a near twig, to follow her back to the material in a moment or two. By hiding in the shrubbery one can see so much of interest at nesting-time. But first of all, would bird-lovers induce parent birds to choose the home grounds, preparation must be made some time in advance.
Trees must be planted and allowed to grow naturally, not in clipped or distorted forms. Birds love natural growth. They recognize wild things and nooks when these are planned and made to grow in private grounds. Now and then a tree root upturned; a pile of boughs; a heap of cuttings and prunings the gardener would have condemned to the fire; a bit of space overlooked by the lawn-mower, moist and grass-tangled; woodpiles and logs left where they are until moss and toadstools have covered them, and bugs have housed in them—a thousand things people, in their love of order and neatness, dispose of at sight—would prove untold attraction to the birds. Too many homes in city and country are not frequented by these visitors, who really prefer our grounds to the woods when once they learn their welcome. When induced for a single season to build in cultivated places, a pair of birds will return, often bringing several other pairs with them.
It seems as if certain birds are popular among their people, and "set the pace," as it were, in the matter of nesting habits. The places they frequent are sought after by the rest; and not only by their own kind or species, but by birds of different character.
It is with birds as with humankind—many different sorts make up a popular neighborhood. Bird families do not choose to wander away to some remote part of the country and make a settlement. Indeed, as we have studied them, birds delight in fraternal good-fellowship.
Within an area of two hundred feet square in our grounds we have counted thirty-three varieties in this single season. Of these, fifteen have nested—the linnet, two varieties of goldfinch, chipping-sparrow, song-sparrow, humming-bird, towhee, mocker, pewee, phœbe, oriole, thrush, black-headed grosbeak, yellow warbler, and bush-tit. Some of these have nested twice or three times in our long season. These birds are not seen to quarrel nor to disagree as to the locations chosen. Each respects the other's rights, even to keeping guard over one another's children. Be a single family or even one little bird in trouble, each and all of these birds mentioned come to the rescue. At such times the varying notes are a sound both interesting and amusing. Food and water are always before these birds in shady places or in the sunshine. Materials for nest-building are spread before them the whole six months of the nesting-season, from horsehair and strings to mud, paper, rags, bark, feathers, cotton, dry grasses, lint, and a general assortment of lichens. The linnets, goldfinches, hummers, orioles, yellow warblers, and bush-tits lose their wits over the fluffy white cotton. Our song-sparrows and phœbes are not seen to use other than material of dark color, like brown rootlets and mud for phœbes, and old grass blades and dark horsehair for the sparrows. Mention has been made as to most of the others.
The linnets are the easier suited. A black last year's sparrow's nest put in the box under the eaves in place of a new white cotton one is accepted, with no questions asked. We have substituted nest for nest many times, and find there is no choice. Also, we have substituted young birds of the same species, and each and all are adopted. Sometimes we find an orphan birdling, which is sure to be cared for provided it be placed in the nest of any kind, motherly bird. Of course, in thus trading or causing to be adopted young birds, we are careful not to give a seed-eater to a meat-eater, and vice versa.
An insect fare would hardly agree with nurslings accustomed to regurgitated food, like the finches and hummers. Once we rescued a tiny young hummer from a "wicked boy," who had come to the treasure by theft. The little thing was nearly dead with cold and hunger. But we knew exactly where to find a dear, motherly old soul in the person of a humming-bird, who had just completed her nest. We placed the orphan in the frail cradle, so weak it could scarcely open its beak. The old bird came at once, cuddled and coddled the baby as only a humming-bird can do, with her small, soft breast. In ten minutes the wee one was having its supper, and it was raised by the foster-parent.
There seems to be something in the breast of mother birds at the nesting-season akin to human instinct. All these interesting studies go on with us at our door. No cats are allowed within certain bounds. And any home may be the same if the dwellers will take the trouble. An ideal corner in a school-yard would be one in which birds were taught confidence and dependence. Birds are subject to cultivation and encouragement.
If one is just making a start toward this, quick movement in the shrubbery should not be indulged in. Loud, sudden noises and throwing balls or other things, at the commencing of the nest season, frighten the birds. One must learn to stand stock-still and listen and look. Birds notice movement more than sound. Sidewise motions disturb, where straight, go-ahead methods are not noticed.
