American Robin, Turdus migratorius. Abundant and common throughout North America, breeding up as far north as northern Alaska and wintering down in Mexico and Central America. Despite being a “known” migratory species, many flocks will stay throughout the U.S. year-round. Feed mainly on insects, worms, and berries. Robin’s travel in large flocks, ranging from around 25 individuals to several hundred. A frequently seen bird, with gray/brown back and orange front. There is a slight sexual dimorphism in this species with the males having a darker head. Juveniles are spotty and the orange gradually appears as they age. Robins that stick to the eastern half of North America have white tips on the ends of their outer tail feathers. It is not fully known why this is.
