Common Starling - Description

Description

It is among the most familiar of birds in temperate regions. It is 19–23 cm (7.5–9.1 in) long, with a wingspan of 31–44 cm (12–17 in) and a weight of 58–101 g (2.0–3.6 oz). Among standard measurements, the wing chord is 11.8 to 13.8 cm (4.6 to 5.4 in), the tail is 5.8 to 6.8 cm (2.3 to 2.7 in), the culmen is 2.5 to 3.2 cm (0.98 to 1.3 in) and the tarsus is 2.7 to 3.2 cm (1.1 to 1.3 in). The plumage is shiny black, glossed purple or green, and spangled with white, particularly strongly so in winter. Adult male European Starlings are less spotted below than adult females. The throat feathers are long and loose, and used as a signal in display. Juveniles are grey-brown, and by their first winter resemble adults though often retain some brown juvenile feathering especially on the head in the early part of the winter. The legs are stout, pinkish-red. The bill is narrow conical with a sharp tip; in summer, it is yellow in females, and yellow with a blue-grey base in males, while in winter and in juveniles, it is black in both sexes. Moulting occurs once a year, in late summer after the breeding season is finished; the fresh feathers are prominently tipped white (breast feathers) or buff (wing and back feathers). The reduction in the spotting in the breeding season is achieved by the white feather tips largely wearing off. Starlings walk rather than hop. Their flight is quite strong and direct; they look triangular-winged and short-tailed in flight.

Confusion with other species is only likely in Iberia, the western Mediterranean and northwest Africa in winter, when it has to be distinguished from the closely related Spotless Starling, which, as its name implies, has less spotting on its plumage. The Spotless Starling can also be diagnostically distinguished at close range by its longer throat feathers. At a more basic level, adult male European Blackbirds can easily be distinguished by more slender body shape, longer tail, and behaviour; they hop instead of walking and do not probe for food with open bills. In flight, only the much paler waxwings share a similar flight profile.

Famous quotes containing the word description:

    The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.
    Horace Walpole (1717–1797)

    Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.
    Henry David Thoreau (1817–1862)

    It [Egypt] has more wonders in it than any other country in the world and provides more works that defy description than any other place.
    Herodotus (c. 484–424 B.C.)
