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.
