Yucatan Nightjar

The Yucatan nightjar is 24 to 25.5 cm (9.4 to 10 in) long. One male weighed 65.5 g (2.3 oz) and three females 51.2 to 64.3 g (1.8 to 2.3 oz). The male's upperparts are grayish brown. The crown has blackish brown spots and grayish white speckles, and the back and rump have buff and cinnamon speckles and broad blackish brown streaks. It has a broad tawny or buff collar on the nape and the sides of the neck. The tail is brown with faint tawny bars; the three outermost pairs of feathers have wide white tips and the innermost pair grayish brown mottling on the tips. The wings are brown to grayish brown with tawny spots and bars. The face is tawny with blackish brown speckles. The chin and throat are dark brown with cinnamon bars and a narrow white band below the latter. The breast is brown with buff and cinnamon speckles, and the belly and flanks are blackish brown with cinnamon speckles, brown bars, and many white spots. The female is similar to the male but the pale tips of the outer tail feathers are much smaller and buff, not white.

The Yucatan nightjar is a year-round resident of Mexico's Yucatán Peninsula and Cozumel off its coast. It is a nonbreeding visitor to Belize and northwestern Honduras, and there are a few reports from northern Guatemala in that season as well. It inhabits "scrub and brushy woodland [and] forest edge".

The Yucatan nightjar is nocturnal. It hunts for flying insects by sallying from a perch and possibly also from the ground.
