The snowy albatross, also known as the white-winged albatross or goonie, is a majestic seabird belonging to the Diomedeidae family. It is recognized for its impressive wingspan, which is the largest of any living bird, and its predominantly white plumage that becomes whiter with age. The snowy albatross is distinguished by its large pink bill and feet, and the males exhibit whiter wings than females.
Adult snowy albatrosses have white bodies contrasted with black and white wings. The wings of males are predominantly white, with only the tips and trailing edges presenting as black. This species is the whitest within its complex, with others showing more brown and black on the wings and body. A salt gland above their nasal passage helps them excrete excess salt due to their oceanic diet.
The snowy albatross boasts a wingspan that can exceed 3.5 meters (11 feet), with an average span of around 3.1 meters (10 feet 2 inches). Body length ranges from 107 to 135 cm (3 feet 6 inches to 4 feet 5 inches), with females being slightly smaller than males. Adults typically weigh between 5.9 to 12.7 kg (13 to 28 lb).
This bird has a circumpolar range in the Southern Ocean and breeds on islands such as South Georgia, Crozet, Kerguelen, Prince Edward, and Macquarie. It is also seen feeding year-round off the coast of New Zealand and is known for its extensive flights, sometimes circumnavigating the Southern Ocean three times in a year.
The snowy albatross is a far-ranging bird, spending most of its life in flight and landing only to breed and feed. It is capable of gliding for hours without flapping its wings, thanks to its large wingspan.
During courtship, snowy albatrosses engage in a variety of displays, including spreading their wings, head-waving, bill-rapping, and producing a range of vocalizations from screams and whistles to grunts and bill clapping.
Snowy albatrosses are monogamous, often mating for life, and breed biennially. They lay a single white egg with a few spots in a large grassy nest. Incubation takes about 11 weeks, with both parents sharing the responsibility. The chicks are nurtured by both parents, who take turns foraging for food.
The snowy albatross is part of the wandering albatross species complex, which includes the Tristan albatross and the Antipodean albatross. It can be distinguished from its relatives by its whiter plumage and larger size.
These birds feed on cephalopods, small fish, and crustaceans, often foraging further out in the open ocean than other albatross species. They are known to follow ships and can make shallow dives to capture their prey.
The IUCN lists the snowy albatross as vulnerable. Threats include longline fishing and pollution. Conservation measures have been implemented in some regions to reduce bycatch and protect their breeding grounds.
