Description
The adult magpie is a fairly solid, sturdy bird ranging from 37 to 43 cm (14.5–17 in) in length with a 65–85 cm (26–33 in) wingspan, and weighing 220–350 g (8–12 oz). Its robust wedge-shaped bill is bluish-white bordered with black, with a small hook at the tip. The black legs are long and strong. The plumage is pure glossy black and white; both sexes of all subspecies have black heads, wings and underparts with white shoulders. The tail has a black terminal band. The nape is white in the male and light greyish-white in the female. Mature magpies have dull red eyes, in contrast to the yellow eyes of currawongs and white eyes of Australian ravens and crows. The main difference between the subspecies lies in the "saddle" markings on the back below the nape. Black-backed subspecies have a black saddle and white nape. White-backed subspecies have a wholly white nape and saddle. The male Western Australian subspecies dorsalis is also white-backed, but the equivalent area in the female is scalloped black.
Juveniles have lighter greys and browns amidst the starker blacks and whites of their plumage; two or three year old birds of both sexes closely resemble and are difficult to distinguish from adult females. Immature birds have dark brownish eyes until around two years of age. Australian Magpies generally live to around 25 years of age, though ages of up to 30 years have been recorded. The reported age of first breeding has varied according to area, but the average is between the ages of three and five years.
Well-known and easily recognisable, the Australian Magpie is unlikely to be confused with any other species. The Pied Butcherbird has a similar build and plumage, but has white underparts unlike the former species' black underparts. The Magpie-lark is a much smaller and more delicate bird with complex and very different banded black and white plumage. Currawong species have predominantly dark plumage and heavier bills.

Famous quotes containing the word description:
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“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.)
