[2] The tawny-collared nightjar was originally described as Caprimulgus salvini; Antrostomus was later split as a separate genus.

It has a broad tawny or buff collar on the nape and the sides of the neck that give the species its name.

[3] The tawn-collared nightjar is found in northeastern Mexico, from Nuevo León and Tamaulipas south to Veracruz.

It inhabits arid to semihumid landscapes including brushy woodland, thorn forest, and dense scrublands.

The clutch size is two eggs, probably laid directly on the ground with no nest as is common among nightjars.

The tawny-collared nightjar's song is "an abrupt, clipped chi-wihw' or tchi-wheeu, repeated rapidly".
