A nightjar of the lowlands of northeastern Mexico, inhabiting dry scrub and open areas with scattered bushes.
Males and females have different wing markings. The upperparts are blackish brown with dark streaks and spots, and a narrow tawny-buff collar crosses the nape. Males have tawny wing bars; females have paler buff bars.
It uses dry lowland scrub and open areas with scattered bushes. At dusk and dawn it sings from mid-level perches in trees or bushes, and at night it catches insects in flight.
Breeding occurs from April to August. The clutch is two white eggs with sparse brown and gray markings.
Its song is a rapid repetition of short phrases rendered as yip willow or chip wow.
Neither sex has a white wing bar. The three outer pairs of tail feathers have white tips, narrower in females than in males.
