- Habitat
- Highly adaptable open-country nightjar: forests, grasslands, prairies, sagebrush, savannah, coastal sand dunes/beaches, burned or logged forest clearings, rock outcrops, and urban areas (including flat gravel rooftops), from sea level up to roughly 2,500-3,000 m elevation
- Fakta menarik
- Despite its name, the Common Nighthawk isn't a hawk at all but a member of the nightjar family, and males perform a dramatic "booming" courtship dive in which air rushing through their wingtip feathers produces a sudden low, bull-like sound.
