From Wikipedia: "The common nighthawk is a medium-sized crepuscular or nocturnal bird of the Americas within the nightjar family, whose presence and identity are best revealed by its vocalization. Typically dark, displaying cryptic colouration and intricate patterns, this bird is difficult to spot with the naked eye during the day. "

Usually don’t nest in streets, on roof tops or tops of building that have tar and pebbles. Probably had juvenile close the just left the nest?
