Diet
 The tree swallow eats flying insects like beetles, horseflies, moths, grasshoppers, and dragonflies. They search for insects over land and water and catch their prey in the air. In the winter, they may feed on berries.
Life Cycle  Males arrive at the breeding territory a week before the females. Once the females arrive, breeding pairs will form. Male and female pairs will defend their nesting territory. A pair will have more than one nesting site, usually in a tree cavity, in their territory, but they will use only one site for their eggs.
The female builds a cup-shaped nest using grass or pine needles. Both the male and the collect feathers to line the nest. The female tree swallow lays four to six eggs at a rate of one egg per day. The female incubates the eggs and the male guards the nesting site. The eggs hatch in about two weeks. Both the male and the female feed the chicks. The chicks fledge in about three weeks.
Behavior
 Tree swallows are short-distance migrators. They gather in large flocks in the fall. They are the first swallows to reappear in the spring.
