Subspecies
Caprimulgus vociferus (Sibley and Monroe 1990, 1993) has been split into Eastern Whip-poor-will (Antrostomus vociferus) and Mexican Whip-poor-will (Antrostomus arizonae) following AOU (2010).
May form superspecies with Puerto Rican Nightjar (Antrostomus noctitherus), with which formerly considered conspecific. Differences in vocalizations suggest that Central American subspecies may be better split from nominate, as Mexican Whip-poor-will (Antrostomus arizonae).
