Wandering Albatross - Description

Description

The Wandering Albatross has the largest wingspan of any living bird, typically ranging from 2.51 to 3.5 m (8 ft 3 in to 11 ft 6 in), with a mean span of 3.1 m (10 ft 2 in) in the Bird Island, South Georgia colony and an average of exactly 3 m (9 ft 10 in) in 123 birds measured off the coast of Malabar, New South Wales. The longest-winged examples verified have been about 3.7 m (12 ft 2 in). Even larger examples have been claimed, with two giants reportedly measuring 4.22 m (13 ft 10 in) and 5.3 m (17 ft 5 in) but these reports remain unverified. As a result of its wingspan, it is capable of remaining in the air without beating its wings for several hours at a time (travelling 22 m for every metre of drop). The length of the body is about 107 to 135 cm (3 ft 6 in to 4 ft 5 in) with females being slightly smaller than males. Adults can weigh from 5.9 to 12.7 kg (13 to 28 lb), although most will weigh 6.35 to 11.91 kg (14.0 to 26.3 lb). Immature birds have been recorded weighing as much as 16.1 kg (35 lb) during their first flights (at which time they may still have fat reserves that will be shed as they continue to fly). The plumage varies with age, with the juveniles starting chocolate brown. As they age they lose their color and get whiter. The adults have white bodies with black and white wings. Males have whiter wings than females with just the tips and trailing edges of the wings black. They also show a faint peach spot on the side of the head. The Wandering Albatross is the whitest of the Wandering Albatross species complex, the other species having a great deal more brown and black on the wings and body as breeding adults, very closely resembling immature Wandering Albatrosses. The large bill is pink, as are the feet. They also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of ocean water that they imbibe. It excretes a high saline solution from their nose.

Famous quotes containing the word description:

    I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.
    Thomas Jefferson (1743–1826)

    God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.
    Lyndon Baines Johnson (1908–1973)

    A sound mind in a sound body, is a short, but full description of a happy state in this World: he that has these two, has little more to wish for; and he that wants either of them, will be little the better for anything else.
    John Locke (1632–1704)
