American Robins are fairly large songbirds with a large, round body, long legs, and fairly long tail. Robins are the largest North American thrushes, and their profile offers a good chance to learn the basic shape of most thrushes. Robins make a good reference point for comparing the size and shape of other birds, too. They measure 20 to 28 centimeters in lenth, with a wingspan of 31 to 40 centimeters. American Robins are gray-brown birds with warm orange underparts and dark heads. In flight, a white patch on the lower belly and under the tail can be conspicuous. Compared with males, females have paler heads that contrast less with the gray back. These are industrious and authoritarian birds that bound across lawns or stand erect, beak tilted upward, to survey their environs. When alighting they habitually flick their tails downward several times. In fall and winter they form large flocks and gather in trees to roost or eat berries. American Robins are common across the continent in gardens, parks, yards, golf courses, fields, pastures, tundra, as well as deciduous woodlands, pine forests, shrublands, and forests regenerating after fires or logging. This species is of low conservation concern.
- Although robins are considered harbingers of spring, many American Robins spend the whole winter in their breeding range. But because they spend more time roosting in trees and less time in your yard, you're much less likely to see them.
- Robins eat different types of food depending on the time of day: more earthworms in the morning and more fruit later in the day. Because the robin forages largely on lawns, it is vulnerable to pesticide poisoning and can be an important indicator of chemical pollution.
- The oldest recorded American Robin was 13 years and 11 months old.
