Medium-sized nightjar found in a wide range of habitats, from dry coastal scrub to the edge of cloud forest in the Andes up to 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. Andean birds give a high, thin “tseeeeeu,” while coastal birds in Peru give a different series of “cweeo” notes.
