American robin Smithsonian's National Zoo and Conservation

One of most common bird species in North America, American robins can be heard singing their cheerful melody in diverse habitats, from deep forest interiors, to rural pastures, to city parks and backyard gardens. They are thought of as the "bringers of spring," due to the species' reputation for flying south for the winter and traveling northward during the springtime.
