The American Robin (Turdus migratorius) is the state bird of Connecticut, Michigan, and Wisconsin. It's a migratory songbird of the thrush family.
Description:
The American Robin is 25-28 cm (10-11 in) long. It has gray upperparts and head, and orange underparts, usually brighter in the male; the similarity between this coloring and that of the smaller and unrelated European Robin (Erithacus rubecula) led to its common name. There are seven races, but only T. m. confinus in the southwest is particularly distinctive, with pale gray-brown underparts.
During the breeding season, the adult males grow distinctive black feathers on their heads; after the breeding season they lose this eye-catching plumage.
Distribution:
This bird breeds throughout Canada and the United States. While Robins occasionally overwinter in the northern part of the United States and southern Canada, most winter in the southern parts of the breeding range and beyond, from the southern U.S.A. to Guatemala. Most depart south by the end of August and begin to return north in February and March. (Exact dates vary with latitude and climate, of course.)
This species is a very rare vagrant to western Europe. In autumn 2003, migration was displaced eastwards leading to massive movements through the eastern USA. Presumably this is what led to no fewer than three American Robins being found in Great Britain, with two attempting to overwinter in 2003-4, one eventually being taken by a Sparrowhawk.
As with many migratory birds, the males return to the summer breeding grounds before the females and compete with each other for nesting sites. The females then select mates based on the males' songs, plumage, and territory quality. The females build the nest and lay three or four blue eggs in the lined cup. Incubation, almost entirely by the female is 11-14 days to hatching, with another 15-16 days to fledging. Two broods in a season are common.
Habitat:
The American Robin's habitat is all sorts of woodland and more open farmland and urban areas. Food is the typical thrush mixture of insects, earthworms, and berries. Robins are frequently seen running across lawns, picking up earthworms by sight or sound.
Song: The American Robin, like many thrushes, has a beautiful and complex song, and in contrast to other thrushes, its song is almost continuous. Its song is commonly described as a cheerily carol song. The song is made of discrete units, often repeated, and spliced together into a string with brief pauses in between. The song varies regionally, and its style varies by time of day. American Robins will often be among the last songbirds singing as the evening sets in.
In addition to its song, the American Robin has a number of calls used for communicating specific information. When a ground predator approaches but does not directly threaten, Robins will make a "PEEK!! tut tut tut tut..." warning call. When a nest or Robin is being directly threatened, another call is used, which sounds like a horse's whinny. Even during nesting season, when Robins exhibit mostly competitive and territorial behavior, they may still band together to drive away a predator. Robins also make a very high-pitched sound when a hawk or other bird of prey is seen; other robins will repeat the sound, seek cover, and stop moving. During the colder parts of the year, the American Robin gathers in flocks around food sources, and there is yet another call that is heard in such flocks.
