Rufous Nightjar is a large, brownish nightjar with a narrow, buffish colored hindneck collar, and a whitish throat band. There is no white in the wings, and females also lack any white in the tail. Rufous Nightjar is sometimes suggested to form a superspecies with the paler and browner-plumaged Chuck-will’s-widow (Antrostomus carolinensis), which breeds in North America and the northern Bahamas, but migrates to the northern Neotropics for the winter. Rufous Nightjar occurs in southern Central America, on St. Lucia in the Lesser Antilles, and across much of northern and eastern South America, east of the Andes, where it usually is fairly common. At least five subspecies are recognized across the broad range of Rufous Nightjar.
