The kingbird will worry the hawk as a whiffet dog will worry a bear. It is by his persistence and audacity, not by any injury he is capable of dealing his great antagonist. The kingbird seldom more than dogs the hawk, keeping above and between his wings, and making a great ado; but my correspondent says he once “saw a kingbird riding on a hawk’s back. The hawk flew as fast as possible, and the kingbird sat upon his shoulders in triumph until they had passed out of sight,”—tweaking his feathers, no doubt, and threatening to scalp him the next moment. That near relative of the kingbird, the great crested flycatcher, has one well-known peculiarity: he appears never to consider his nest finished until it contains a cast-off snake-skin. My alert correspondent one day saw him eagerly catch up an onion skin and make off with it, either deceived by it or else thinking it a good substitute for the coveted material. One day in May, walking in the woods, I came upon the nest of a whip-poor-will, or rather its eggs, for it builds no nest,—two elliptical whitish spotted eggs lying upon the dry leaves. My foot was within a yard of the mother bird before she flew. I wondered what a sharp eye would detect curious or characteristic in the ways of the bird, so I came to the place many times and had a look. It was always a task to separate the bird from her surroundings, though I stood within a few feet of her, and knew exactly where to look. One had to bear on with his eye, as it were, and refuse to be baffled. The sticks and leaves, and bits of black or dark brown bark, were all exactly copied in the bird’s plumage. And then she did sit so close, and simulate so well a shapeless, decaying piece of wood or bark! Twice I brought a companion, and, guiding his eye to the spot, noted how difficult it was for him to make out there, in full view upon the dry leaves, any semblance to a bird. When the bird returned after being disturbed, she would alight within a few inches of her eggs, and then, after a moment’s pause, hobble awkwardly upon them.
