Medium-sized nightjar found in a wide range of open habitats from sea level up to the edge of cloud forest in the Andes (4,400 m). Cryptically patterned in brown and gray like other nightjars. Both sexes have a buffy collar around the neck and whitish or buffy bands across each wing. Also look for the relatively long, squared-off tail. Nocturnal, and therefore most easily detected and identified by voice. Song a high, thin “tseeeeeu.”
