Diet

The American robin eats a wide variety of foods including fruits and berries, worms, grubs, and caterpillars. In winter, its diet is made up largely of berries. It is often seen on lawns in the morning looking for earthworms.
Life Cycle

Robins mate in the spring from April through July. A female may have two or three broods a season. The female builds a cup-shaped nest with twigs, grass, and feathers. She spreads mud on the inside of the nest with her breast. After she lines the nest with mud, she adds grass and other soft materials. Sometimes the male helps collect materials for the nest.

The nest is built five to fifteen feet above the ground in a tree or bush. Sometimes a robin builds its nest on a window ledge. The female lays three to five light blue eggs. The female incubates the eggs for about two weeks.
Behavior

The male robin uses its voice to protect its territory and to attract a mate. It is often one of the first birds heard in the spring!
