American Robins feed on a mixture of both wild and cultivated fruits, berries, earthworms, and insects such as beetle grubs, caterpillars, and grasshoppers. Breeds in the spring shortly after returning from the migration to their more northerly habitat. Breeding season is from April through July. The Robin is one of the first birds to begin laying eggs and normally has two or three broods. The cup-shaped nest is built by the female, who builds the outer foundation with long coarse grass, twigs, paper and feathers woven together.
