At a Glance
In mountain forests of the southwest, this shy nightbird is fairly common in summer. Until recently, it was considered to belong to the same species as the Eastern Whip-poor-will; its voice has a similar pattern, but a rougher and lower tone quality.

Behavior
Eggs
2. Whitish, either unmarked or very lightly marked with brown. Incubation is by both parents (usually more by female), 19-21 days.
Young
Cared for by both parents. Adults feed young by regurgitating insects. Age of young at first flight about 20 days.
Feeding Behavior
Forages at night, especially at dusk and dawn and on moonlit nights. Forages by flying out from a perch in a tree, or in low, continuous flight along the edges of woods and clearings; sometimes by fluttering up from the ground. Captures insects in its wide, gaping mouth and swallows them whole.
Diet
Insects. Feeds on night-flying insects, especially moths, also beetles, mosquitoes, and many others.
Nesting
Male sings at night to defend territory and to attract a mate. Courtship behavior not well known; male approaches female on ground with much head-bobbing, bowing, and sidling about. Nest site is on ground, in woods but often near the edge of a clearing, on open soil covered with dead leaves or pine needles. No nest built, eggs laid on flat ground.
Conservation
Conservation Status
Still fairly common in its limited U.S. range.
