Range. - North America east of the Plains; north to the southern parts of the British possessions; winters along the Gulf coast and southward.

This species is well known, by sound, in nearly all parts of its range, but comparatively few ever observed the bird, and probably the greater number mistake the Nighthawk for this species. The two species can readily be distinguished at a distance by the absence of any pronounced white marking in the wings, and by the white tips to the outer tail feathers in the present species, while the Night Hawk has a prominent white band across the tail, but the top is black, and the tail slightly forked. The Whip-poor-will, rarely leaves its place of concealment before dark, and is never seen flying about cities, as are the Night-hawks. In their pursuit of insects, they glide like a shadow over fields and woods, their soft plumage giving forth no sound as their wings cleave the air. Until late at night, their whistling cry "whip-poor-will," repeated at intervals, rings out in all wooded hilly districts. Their two eggs are deposited on the ground among dead leaves, generally in dense woods. They are grayish white or cream color marbled with pale brown and gray, with faint er markings of lilac.
