The sides of the head are slightly darker brown than the rest of the body ⁽⁴⁾ and the legs and feet are pale grey ⁽²⁾. A white crescent surrounds the eye, and the bill is black with a yellow-orange groove in the lower jaw ⁽⁴⁾.

Sooty albatross biology

At three to four years old, the sooty albatross performs an elegant courtship display at a nest site. The pair bond formed following these displays may last for life, although the pairs will not begin to breed until they are 9 to 16 years. Laying occurs between September and December, with a single egg laid in a nest made from a mound of mud and plant matter. The egg is incubated by both parents for 65 – 75 days. Parental care continues after hatching, and the chick is fed and guarded for the next five months, at which time it leaves the nest and becomes independent ⁽²⁾.

The sooty albatross eats cephalopods, fish, crustaceans and carrion, but unlike many other albatross species, it seldom follows fishing vessels to catch food ^{(4) (5)}.

Sooty albatross range

Spending most of the year at sea in the South Atlantic and Indian Oceans, the sooty albatross nests on many of the islands in these oceans, including Gough Island, Tristan da Cunha Islands, Prince Edward and Marion Islands, St. Paul Island, Amsterdam Island and the Crozet and Kerguelen archipelagos ^{(4) (5)}.

Sooty albatross habitat

Inhabits sub-Antarctic and subtropical marine waters. Nests amongst vegetation on inland and seaward cliffs of oceanic islands ^{(2) (5)}.

Sooty albatross status

The sooty albatross is classified as Endangered (EN) on the IUCN Red List 2004 ⁽¹⁾ and is listed on Appendix II of the Convention on Migratory Species ⁽³⁾, as well as Appendix II of the Bonn Convention ⁽²⁾. It is also listed as a Vulnerable Species on Schedule 2 of the New South Wales Threatened Species Conservation Act 1995 ⁽²⁾.

Sooty albatross threats

Introduced rats are known to consume albatross eggs and the sooty albatross is thought to be vulnerable to avian cholera and the erysipelas bacteria ^{(2) (6)}. Pollution from plastics, oils and chemicals is also a threat ⁽²⁾.

Sooty albatross conservation

The sooty albatross is protected in some of its range; it exists in one World Heritage Site, one Special Nature Reserve, and several other nature reserves. There are continuing population monitoring and foraging studies, and it has been proposed that key sites are re-assessed regularly ⁽⁴⁾.

Carrion

Dead flesh.

Cephalopoda

From the Greek for ‘head-foot’, a class of molluscs that occur only in marine habitats. All species have grasping tentacles, and either an internal or external shell. Includes nautiloids, cuttlefish, squids, octopuses, and extinct ammonites and belemnites.

Crustacea

Diverse group of arthropods (a phylum of animals with jointed limbs and a hard chitinous exoskeleton) characterised by the possession of two pairs of antennae, one pair of mandibles (parts of the mouthparts used for handling and processing food) and two pairs of maxillae (appendages used in eating, which are located behind the mandibles). Includes crabs, lobsters, shrimps, slaters, woodlice and barnacles.
