A medium-sized, dark nightjar of tepui highlands, difficult to identify by plumage alone. Cryptically patterned with dark brown and gray accented with buffy and whitish bars and spots. Male has a white band in the wing, which the female lacks. Uncommon, found in humid forest and edges, as well as humid scrub close to forested areas. Distinctive voice is a hoarse whistle “whoEEuuu”, given repeatedly. Larger than the similar Band-winged Nightjar, and smaller than Blackish Nightjar, but best identified by voice and habitat.
