Nighthawks are attractive, big-eyed nocturnal birds that catch flying insects in huge, gaping mouths. They have very long wings and a buoyant, moth-like flight. By day they roost in trees, on posts, roofs, wires, or on the ground, using their intricate camouflaged plumage to avoid predators, and they start to become active in the late afternoon. These birds -- mostly males, shown by their white throats -- were living in a small grove of cottonwood trees at the White Mountain Research Station in Bishop, California; others were in eastern Kansas or at the Pawnee Grasslands in northeastern Colorado. Two female common nighthawks from Panama are shown here. |
