Mexican Whip-poor-will

Antrostomus arizonae

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.
Conservation status Still fairly common in its limited U.S. range.
Family Nightjars
Habitat Pine-oak woods in mountains. Breeds in woodland in mountains and canyons, mostly in the pine-oak zone at middle elevations, sometimes higher.

Nesting
