Feeding Behavior
Forages mostly by sitting on the ground or on a low perch and making short flights upward to catch passing insects. Occasionally forages in longer, sustained flights. Does most foraging at dawn and dusk or on moonlit nights. Sometimes picks up insects (and possibly spiders) from ground.
Eggs
2. White, sometimes with a few spots. Incubation is by both parents, 20-21 days. Young: Both parents feed young, by regurgitating insects. If nest site is disturbed, parents can move either the eggs or young to a new location. Downy young can move on their own by hopping or somersaulting across the ground. Age of young at first flight 20-23 days. May raise 2 broods per year.

Diet
Insects. Feeds mainly on night-flying insects, especially moths and beetles, also some grasshoppers, flies, and others. Insects up to one and a half inches long can be swallowed whole.
Nesting
Male calls at night in spring to defend territory and to attract a mate. Nest site is on ground, on bare open soil, rock, or gravel, sometimes on dead leaves or pine needles. Often shaded by a shrub or overhanging rock, and sometimes in secluded rock shelter. No nest built, although bird may make a slight scrape in soil. Same site may be used more than one year.
