The great albatrosses are seabirds in the genus Diomedea in the albatross family. The genus Diomedea formerly included all albatrosses except the sooty albatrosses, but in 1996 the genus was split, with the mollymawks and the North Pacific albatrosses both being elevated to separate genera. [1]

Contents

The great albatrosses themselves form two species complexes, the wandering and Amsterdam albatrosses, and the royal albatrosses. The splitting of the great albatrosses into six or seven species has been accepted by most, though not all, authorities. [2]

Description

The snowy albatross and the southern royal albatross are the largest of the albatrosses and are among the largest of flying birds. They have the largest wingspans of any bird, being up to 3.5 m (11 ft) from tip to tip, although the average is a little over 3 m (9.8 ft). Large adult males of these two species may exceed 11 kg (24 lb) in weight, as heavy as a large swan.

The great albatrosses are predominantly white in plumage as adults, with birds becoming whiter as they age. The two royal albatrosses at all ages and the larger, older male snowy albatrosses are totally white-bodied, while adult females and younger animals of the other species have dark pencilling marks on the edges of their feathers. Generally the smaller species or subspecies and the juveniles have more dark brown colour. The recently discovered Amsterdam albatross retains the dark brown plumage of juvenile birds into adulthood.

Habitat and range

The great albatrosses range across the Southern Ocean, and nest (for the most part) on isolated oceanic islands. The snowy albatrosses nest on islands around the Southern Ocean, from the Atlantic Ocean (South Georgia and Tristan da Cunha), to the Indian Ocean and New Zealand's Subantarctic islands. The royal albatrosses nest only on New Zealand's Subantarctic islands, with one unusual colony on New Zealand's Otago Peninsula.

Taxonomy

The genus Diomedea was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae . [3] The genus name is from Greek mythology. When the hero Diomedes died his companions were turned into white seabirds. [4] The type species was designated as the snowy albatross (Diomedea exulans) by George Robert Gray in 1840. [5] [6]

Species

The genus contains six species: [7]

Fossils

The earliest known fossils of the genus are from the Middle Miocene, about 12–15 mya. By that time, the genera Phoebastria and Diomedea had already diverged.

Fossil species [8] [9]

At least four species were found in the Early Pliocene deposits of Lee Creek Mine, North Carolina in the US. [8] These may in part be identical with the forms mentioned above. Assignment of the undescribed taxa to Diomedea is tentative since most of them were discovered before the splitting of this genus. Especially the Southern Hemisphere species probably belong to other genera.

Procellariiformes is an order of seabirds that comprises four families: the albatrosses, the petrels and shearwaters, and two families of storm petrels. Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order, or more commonly all the families except the albatrosses. They are almost exclusively pelagic, and have a cosmopolitan distribution across the world's oceans, with the highest diversity being around New Zealand.

<span class="mw-page-title-main">Black-footed albatross</span> Species of bird

The black-footed albatross is a large seabird of the albatross family Diomedeidae from the North Pacific. All but 2.5% of the population is found among the Northwestern Hawaiian Islands. It is one of three species of albatross that range in the northern hemisphere, nesting on isolated tropical islands. Unlike many albatrosses, it is dark plumaged.

<span class="mw-page-title-main">Mollymawk</span> Genus of birds

The mollymawks are a group of medium-sized albatrosses that form the genus Thalassarche. The name has sometimes been used for the genus Phoebetria as well, but these are usually called sooty albatrosses. They are restricted to the Southern Hemisphere, where they are the most common of the albatrosses. They were long considered to be in the same genus as the great albatrosses, Diomedea, but a study of their mitochondrial DNA showed that they are a monophyletic taxon related to the sooty albatrosses, and they were placed in their own genus.

<i>Phoebetria</i> Genus of birds

The sooty albatrosses are small albatrosses from the genus Phoebetria. There are two species, the sooty albatross, Phoebetria fusca, and the light-mantled albatross, Phoebetria palpebrata.

<span class="mw-page-title-main">Sooty albatross</span> Seabird in the family Diomedeidae

The sooty albatross is a species of marine bird belonging to the albatross family Diomedeidae. It is a medium-sized albatross that sports a sooty-brown or sooty-black color. It can be found in the southern Atlantic Ocean, the southern Indian Ocean, and the Southern Ocean. This bird scavenges for squid, fish, and carrion. Like other albatrosses, these birds mate for life and return to the same breeding spots every season. A single pair will mate every other year on a variety of islands in the southern Atlantic Ocean and the southern Indian Ocean islands. This bird is an endangered species and conservation efforts are taking place.

<span class="mw-page-title-main">North Pacific albatross</span> Genus of birds

The North Pacific albatrosses are large seabirds from the genus Phoebastria in the albatross family. They are the most tropical of the albatrosses, with two species nesting in the Northwestern Hawaiian Islands, one on sub-tropical islands south of Japan, and one nesting on the equator.

<i>Procellaria</i> Genus of birds

Procellaria is a genus of Southern Ocean long-winged seabirds related to prions, and within the order Procellariiformes. The black petrel ranges in the Pacific Ocean, and as far north as Central America. The spectacled petrel is confined to the Atlantic Ocean, and the Westland petrel to the Pacific Ocean. The white-chinned and grey petrel range throughout the higher latitudes of the Southern Ocean.

<span class="mw-page-title-main">Antipodean albatross</span> Species of bird

The Antipodean albatross is a large seabird in the albatross family. Antipodean albatrosses are smaller than snowy albatrosses, and breed in predominantly brown plumage, but are otherwise difficult to distinguish from young snowy albatrosses.

<span class="mw-page-title-main">Northern royal albatross</span> Species of bird

The northern royal albatross or toroa, is a large seabird in the albatross family. It was split from the closely related southern royal albatross as recently as 1998, though not all scientists support that conclusion and some consider both of them to be subspecies of the royal albatross.

<span class="mw-page-title-main">Blue petrel</span> Species of bird

The blue petrel is a small seabird in the shearwater and petrel family, Procellariidae. This small petrel is the only member of the genus Halobaena, but is closely allied to the prions. It is distributed across the Southern Ocean but breeds at a few island sites, all close to the Antarctic Convergence zone.

<span class="mw-page-title-main">Cape petrel</span> Species of bird

The Cape petrel, also called the Cape pigeon, pintado petrel, or Cape fulmar, is a common seabird of the Southern Ocean from the family Procellariidae. It is the only member of the genus Daption, and is allied to the fulmarine petrels, and the giant petrels. They are extremely common seabirds with an estimated population of around 2 million.

<span class="mw-page-title-main">Southern royal albatross</span> Species of bird

The southern royal albatross or toroa, is a large seabird from the albatross family. At an average wingspan of above 3 m (9.8 ft), it is one of the two largest species of albatross, together with the wandering albatross. Recent studies indicate that the southern royal albatross may, on average, be somewhat larger than the wandering albatross in mass and have a similar wingspan, although other sources indicate roughly similar size for the two species and the wandering species may have a larger average wingspan in some colonies.

<span class="mw-page-title-main">Albatross</span> Family of large seabirds

Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes. They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus Diomedea have the longest wingspans of any extant birds, reaching up to 3.7 m (12 ft). The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species.
