Breeds from portions of Alaska, east to Newfoundland, and south to southern California and eastern Virginia. Winters mainly from eastern Panama to Peru and northern Argentina, and casually in Central America.
Found in open and partly- open situations, frequently near flowing water.
Catches food in air over fields, wetlands, and water. If necessary, may forage up to several km from nesting area. Burrows in or uses soil for nest. Forms colonies of various sizes; largest colonies, which may reach several hundred pairs, often occur in artificial sites. When not breeding, may form flocks of hundreds or thousands. Inclement weather and resulting scarcity of food may be important factor in nestling mortality in some years; erosion of nest sites and predators also sometimes destroy nests.
