When the mother bird's suspicion gets the better of her, she often devours the food she has in her beak, so fearful is she of betraying her precious secret. But the next time she comes she may only maneuver briefly before approaching the nest, and then again hesitate and parley with her fears and make false moves and keep her eye on me, as if I had only just appeared upon the scene.
One of the best things a bird-lover can have in front of his house or cabin is a small dead tree with numerous leafless branches. Many kinds of birds love to perch briefly where they can look around them. I would not exchange the old dead plum-tree that stands across the road in front of my lodge for the finest living plum-tree in the world. It bears a perpetual crop of birds. Of course the strictly sylvan birds, such as the warblers, the vireos, the oven-bird, the veery and hermit thrushes, do not come, but many kinds of other birds pause there during the day and seem to enjoy the unobstructed view.
All the field and orchard and grove birds come. In early summer the bobolink perches there, then tiptoes, or tip-wings, away to the meadows below, pouring out his ecstatic song. The rose-breasted grosbeak comes and shows his brilliant front. The purple finch, the goldfinch, the indigo bunting, the bluebird, the kingbird, the phœbe-bird, the great crested flycatcher, the robin, the oriole, the chickadee, the high-hole, the downy woodpecker, the vesper sparrow, the social sparrow, or chippy, pause there in the course of the day, and some of them several times during the day. Occasionally the scarlet tanager lights it up with his vivid color.
But more than all it is the favorite perch of a song sparrow whose mate has a nest not far off. Here he perches and goes through his repertoire of three or four different songs from dawn till nightfall, pausing only long enough now and then to visit his mate or to refresh himself with a little food. He repeats his strain six times a minute, often preening his plumage in the intervals. He sings several hundred times a day and has been doing so for many weeks. The house wren during the breeding-season repeats his song thousands of times a day, while the red-eyed vireo sings continuously from morning till night for several months. How a conscious effort like that would weary our human singers and their hearers! But the birds are quite unconscious, in our sense, of what they are doing.
