American robins feed on a mixture of fruits, berries, Oligochaeta, and insects such as Coleoptera grubs, Lepidoptera, and Orthoptera. Their diet usually consists of about 40% insects and 60% fruits and berries. However, American robins are flexible and will eat whichever food is most available. American robins get a lot of moisture from the foods they eat, especially juicy berries and insects, but they also may need to drink free standing water from pools.
