“On warm summer evenings, Common Nighthawks roam the skies over treetops, grasslands, and cities. Their sharp, electric peent call is often the first clue they’re overhead. In the dim half-light, these long-winged birds fly in graceful loops, flashing white patches out past the bend of each wing as they chase insects. Their range includes all of the continental United States. They have one of the longest migration routes over land through Mexico and Central America to the wintering grounds in southern South America..” – From All About Birds, Cornell Lab of Ornithology
