Brown-and-buff nightbird found in arid scrub and deserts in western Ecuador and northwestern Peru. It is dark brown, heavily mottled with buff, and has a white throat. In flight, it has white crescents near the wingtips and white stripes along the outer tail feathers. Similar to Common Pauraque, but smaller, with a shorter tail and a different voice. Compared to Tschudi's Nightjar, with which it overlaps in northwestern Peru, Scrub is much darker and has a different song. Scrub Nightjar typically gives a clear, whistled, incessantly repeated “tWEE-oh,” more emphatic and not as burry as Common Pauraque.
