Not even the ovenbird contrives that a peep at her eggs shall be so difficult for us. It is next to impossible to find them. Unlike the wicked cowbird, who builds no nest because she has no maternal instinct, the whip-poor-will, who is a devoted mother, makes none because none is needed. Once I happened upon two fuzzy, dark, yellowish-gray, baby whip-poor-wills (mostly mouths) in a hollow of a decayed, lichen-covered log, which was their "comfy" cradle; but the frantic mother, who flopped and tumbled about on the ground around them, whining like a puppy, sent me running away from sheer pity. In the Southern States a somewhat larger whip-poor-will, but with the same habits, is known as chuck-will's-widow. NIGHTHAWK _Called also: Bull-bat; Night-jar; Mosquito-hawk_ Did you ever hear a rushing, whirring, booming sound as though wind were blowing across the bung-hole of an empty barrel? The nighthawk, who makes it, is such a high flyer, that in the dusk of the late afternoon or early evening, when he delights to sail abroad to get his dinner, you cannot always see him; but as {178} he coasts down from the sky--not on a sled, but on his half-closed wings--with tremendous speed, the rush of air through his stiff, long wing feathers makes an uncanny, aeolian music that silly, superstitious people have declared is a bad omen. You might think he would dash out his brains in such a headlong dive through the air, but before he hits the earth, a sudden turn saves him and off he goes unharmed, skimming above the ground and catching insects after the whip-poor-will's manner. He lacks the helpful bristles at the ends of his fly-trap. Don't imagine, because of his name, that he flies about only at night. He is not so nocturnal in his habits as the whip-poor-will. Toward the end of summer, especially, he may be seen coursing over the open country at almost any hour of the day. Once in a while, as he hunts, he calls _peent_--a sharp cry that reminds you of the meadowlark's nasal call-note. Presently, mounting upward higher and higher, at the leisurely rate of a boy dragging his sled up hill, he seems to reach the very clouds, when down he coasts again, faster than a boy's flexible flyer. Listen for the booming noise of this coaster! Evidently he enjoys the sport as much as any boy or girl, for he repeats his sky-coasting very often without having to wait for a snow-storm. Indeed, when winter comes, he is enjoying another summer in South {179} America. Life without insects would be impossible for him.
