American Robin- Turdus migratorius

The American Robin winters all across North America, usually in areas that they can easily find things to eat. As the snow increases in areas they move south, and when the snow is low they are farther north. Their diet is Worms, berries, and insects. During mating season they are monogamists, the females make the nests out of twigs, mud, and leaves. Their eggs are bright blue and are about the same size as a quarter.
