Common Nighthawks usually fly at dusk and at night catching moths and other insects in the dark, but they sometimes can be seen flying high above the ground during the day. In particular, males display during the day where they "peent" and dive sharply to catch wind in their tail feathers and make a buzzing noise.
Poorwills also fly at night, but their wings are all brown, and the call is "poor-will."
Taxonomy: Caprimulgiformes, Caprimulgidae, Chordeilinae.
