High Quality Content by WIKIPEDIA articles! The Common Nighthawk (Chordeiles minor) is a medium-sized crepuscular or nocturnal bird, whose presence and identity are best revealed by its vocalization. Typically dark (grey, black and brown), displaying cryptic colouration and intricate patterns, this bird becomes invisible by day. Once aerial, with its buoyant but erratic flight, this bird is most conspicuous. The most remarkable feature of this aerial insectivore is its small beak belies the massiveness of its mouth. Some claim appearance similarities to owls. With its horizontal stance and short legs, the Common Nighthawk does not travel frequently on the ground, instead preferring to perch horizontally, parallel to branches, on posts, on the ground or on a roof. The males of this species may roost together but the bird is primarily solitary. The Common Nighthawk shows variability in territory size.
