Habitat

Breeds in forests, wooded foothills, mountains, suburban areas.

Range

Breeds from Alaska east to South Dakota, south to southern California and Texas. Winters mainly south of U.S.-Mexico border, but a few winter in southern California.

Discussion

Like many other swallows, the Violet-green lives in colonies, basically because of its feeding needs. Where one finds food there is usually enough for all, and when feeding communally these birds can more readily detect and defend themselves from hawks.

Nesting

4 or 5 white eggs in a grass-and-feather nest in a woodpecker hole, a natural cavity, under the eaves of a building, or in a nest box.
