WINGED MYSTERIES
“Four birds there are that live under one roof, so to speak, for they belong to one order divided into three different families. They are perfectly familiar to most of us who have lived in the real country, and yet they awaken our curiosity anew every season when they return. These birds are the Whip-poor-will, Chimney Swift, Nighthawk, and Humming-bird. The two first return to New England late in April; the two last during the first part of May, but it is better for us to take them all together now in April so as to be ready to recognize the first one that comes.
“The Whip-poor-will comes first. It is a bird of the woods; in size a little less than the Robin, but of a build peculiar to its own family, long and low, a contrast heightened by its short legs and its habit of sitting length-wise on a limb and close to it. In short, it does not perch, it ‘squats.’ Its general colour is black, white, and buff, much streaked and mottled. Its tail is round, half of the three outer feathers white, giving the effect of a white spot.
“All of you children of this wooded hill country know this bird that flies about the house and across the fields to the woods before dawn or soon after dark, making no more noise than the bats, until, stopping to rest, he mechanically jerks out his name, ‘Whip-poor-will-Whip-poor-will-Chuck!’ So lonely and mournful does the cry sound in the distance that many weird stories have been told about the bird. But when the call comes close at hand, it is more cheerful, though always startling.
“This bird builds no nest, but lays its pair of dull white eggs, so marked that they blend with the earth like lichens and mosses, on the bare ground, or at best among a few leaves. But rash as this seems, the protective colour that nature has given to the parents, eggs, and young serves to keep them as safe as many another bird in a well-woven tree nest.
“Then, too, aside from its picturesque qualities, the Whip-poor-will, as Mr. Forbush says of it, ‘is an animated insect trap. Its enormous mouth is surrounded by long bristles which form a wide fringe about a yawning cavity, and the bird flies rather low among the trees and over the undergrowth, snapping up nocturnal insects in flight. It is, perhaps, the greatest enemy of night-moths, but is quite as destructive to May beetles and other leaf-eating beetles.’
