About the Tree Swallow

Also known as: American Tree Swallow, White-bellied Swallow, White-breasted Swallow

Tree Swallows are small birds that breed across much of North America and migrate to Mexico and Central America for the winter. They have dark iridescent upperparts and white underparts. Females have similar plumage to males, although they are typically duller.

Tree Swallows are cavity nesters. They will excavate natural cavities, or use artificial boxes, especially those provided for bluebirds. 4 to 7 eggs are usually laid, and the baby birds hatch after about 14 days of incubation. Fledging occurs in 16 to 24 days.

Tree Swallows feed primiarly on insects. They fly through the air to catch prey items on the wing. They also occasionally feed on fruits.
