American Robin



American Robin - Drozd wędrowny



Cresskill, New Jersey, 2013



Description
The American Robin is the largest, most abundant, and most widespread North American thrush. The presence of this rather tame songster in the backyard setting, together with its loud and musical voice, makes it one of the most easily recognizable birds in North America. The head varies from jet black to gray, with white eye arcs and white supercilia. The throat is white with black streaks, and the belly and undertail feather are white. The Robin has a brown back and a reddish-orange breast, varying from a rich red maroon to peachy orange. The bill is mainly yellow with a variably dark tip, the dusky area becoming more extensive in winter, and the legs and feet are brown. The American Robin is active mostly during the day, and on its winter grounds it assembles in large flocks at night to roost in trees in secluded swamps or dense vegetation.

Habitat

This bird breeds throughout most of North America, from Alaska and Canada southward to northern Florida and Mexico. While Robins occasionally overwinter in the northern part of the United States and southern Canada, most migrate to winter south of Canada from Florida and the Gulf Coast to central Mexico, as well as along the Pacific Coast. Most depart south by the end of August and begin to return north in February and March. The American Robin's breeding habitat is woodland and more open farmland and urban areas. It becomes less common as a breeder in the southernmost part of the Deep South of the United States, and there prefers large shade trees on lawns. Its winter habitat is similar but includes more open areas.

Voice
The male American Robin, as with many thrushes, has a complex and almost continuous song. Its song is commonly described as a cheerily carol, made up of discrete units, often repeated, and spliced together into a string with brief pauses in between. The American Robin is often among the first songbirds singing as dawn rises or hours before, and last as evening sets in.

Diet
The American Robin's diet generally consists of around 40% invertebrates, such as earthworms, beetle grubs, caterpillars and grasshoppers, and 60 percent wild and cultivated fruits and berries. Robins forage primarily on the ground for soft-bodied invertebrates, and find worms by sight, pouncing on them and then pulling them up. Nestlings are fed mainly on worms and other soft-bodied animal prey.
Reproduction

The American Robin begins to breed shortly after returning to its summer range. It is one of the first North American bird species to lay eggs, and normally has two to three broods per breeding season, which lasts from April to July. The nest is most commonly located above the ground in a dense bush or in a fork between two tree branches, and is built by the female alone. The American Robin does not shy away from nesting close to human habitation and will frequently construct nests under eaves or awnings on human homes when such locations provide adequate shelter. Robins are not cavity nesters, and so will generally not use a bird house, but will take advantage of artificial nesting platforms that have been provided. A clutch consists of three to five light blue eggs, and is incubated by the female alone. The eggs hatch after 14 days, and the chicks leave the nest a further two weeks later. The altricial chicks are naked and have their eyes closed for the first few days after hatching. While the chicks are still young, the mother broods them continuously. When they are older, the mother will brood them only at night or during bad weather.

Did you know?



The American Robin is a known reservoir (carrier) for West Nile virus. While crows and jays are often the first noticed deaths in an area with West Nile virus, the American Robin is suspected to be a key host, and holds a larger responsibility for the transmission of the virus to humans. This is because while crows and jays die quickly from the virus, the American Robin survives the virus longer, hence spreading it to more mosquitoes, which then transmit the virus to humans and other species.

The American Robin has a place in Native American mythology. The story of how the robin got its red breast by fanning the dying flames of a campfire to save a Native American man and a boy.
