Yucatan Nightjar is resident on the Yucatan Peninsula, including Cozumel Island, of southeastern Mexico, and in northern Belize (Friedmann et al. 1950, Howell and Webb 1995). It also occurs farther south in Belize and, rarely, to northwestern Honduras, where it may be only a nonbreeding visitor (Russell 1964, Howell and Webb 1995, Jones 2004). Griscom (1932) reported two specimens of Yucatan Nightjar from Guatamela, but van Rossem (1934) identified these as Mexican Whip-poor-will (Antrostomus arizonae). There is a recent report of a singing Yucatan Nightjar from Guatemala, however (Eisermann and Avendaño 2007).
Yucatan Nightjar is restriced to the lowlands.
