Blackbird of America

The blackbird of America or American robin is a migratory Bird-singer of the family of the Muscicapidé S.

The blackbird of America measures between 25 and 28 cm length. It has gray upper parts, and orange lower parts, usually more sunk in the male; its coloration is similar to that European Rouge-gorge, smaller but nonrelated, and often people confuse the two species. There are seven races of blackbirds of America, but only the T.m. confinus in south-west is particularly distinguishable, with its lower parts gray-pale.

During the reproductive season, easily locatable black feathers push on the heads of the adult males; after the reproductive season, they lose this seizing plumage.

This bird reproduces through the Canada and the the United States. Certain blackbirds spend sometimes the winter in the north of the United States and the south of Canada, while surviving on the Aubépine S and the Pommetier S, but the majority pass it at the southern ends of their zone of reproduction; some blackbirds go even to Texas and to the Guatemala. The majority leaves towards the south at the end of August and starts to return in March. (The exact dates vary with the latitude and the climate, of course.)

One saw it migrating towards Western Europe some rare times. With the autumn 2003, the migration was moved towards the east, which brought great migrations towards the east of the United States. Présumément, this led to step less than three lucky finds of blackbirds of America in Great Britain, two of them having tried to spend the winter in 2003-2004, and one being possibly eaten by a sparrowhawk.

As it is the case with the migratory birds, the males return to the estival reproductive zones before the females and are made competition for the places of nesting. The females can choose the males on the criterion of their song. The females build their nest and lay three or four eggs in line. They can make up to 180 outward journeys per day. Incubation, almost entirely by the female, lasts from 11 to 14 days before the blossoming; 15 or 16 days later, the small ones, which weighed 5,5 G with the birth, start to fly. Often, there are two brooded in one season.

The habitat of the blackbird of America includes/understands the timbered areas, agricultural spaces and the urban areas. It nourishes typical receipt with turdinés: a mixture of Insect S, worms and bays. The blackbirds are often seen running through the lawns, raising the worms of ground at sight of eye. They have a large esophagus, and can gather in surfaces of 250.000 individuals. Their larger predator is the domestic cat.

The call of the blackbird of America can result in “stripped, Ti-lulût”.

It is the “bird of state” of the Connecticut, the Michigan and the Wisconsin.
