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.
The snowy albatross, also known as the white-winged albatross, wandering albatross, or goonie, is a large seabird from the family Diomedeidae; they have a circumpolar range in the Southern Ocean. It is the most recently described species of albatross and was long considered to be the same species as the Tristan albatross and the Antipodean albatross. Together with the Amsterdam albatross, it forms the wandering albatross species complex. When the complex was split into four species, the English name of the nominate form was changed from wandering albatross to snowy albatross.
The black-browed albatross, also known as the black-browed mollymawk, is a large seabird of the albatross family Diomedeidae; it is the most widespread and common member of its family.
The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes, which also includes the albatrosses and the storm petrels.
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.
Salvin's albatross or Salvin's mollymawk, is a large seabird that breeds mainly on the Bounty Islands of New Zealand, with scant amounts on islands across the Southern Ocean. A medium-sized mollymawk, it was long considered to be a subspecies of the shy albatross.
The grey-headed albatross also known as the gray-headed mollymawk, is a large seabird from the albatross family. It has a circumpolar distribution, nesting on isolated islands in the Southern Ocean and feeding at high latitudes, further south than any of the other mollymawks. Its name derives from its ashy-gray head, throat and upper neck.
The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a legally binding international agreement signed in 2001 and entered into force on 1 February 2004 when South Africa ratified as the fifth Party to the Agreement.
The shy albatross, also known as shy mollymawk, is a medium-sized albatross that breeds on three remote islands off the coast of Tasmania, Australia, in the southern Indian Ocean. Its lifespan is about 60 years, and it has been seen as far afield as South Africa and the Pacific coast of the United States. As of June 2020, the species is listed as "Endangered" in Australia; there are thought to be 15,000 pairs of shy albatross left. It is Australia's only endemic albatross.
The white-capped albatross is a mollymawk that breeds on the islands off of New Zealand. Not all experts agree that this form should be recognized as a separate species from the shy albatross, Thalassarche cauta. It is a medium-sized black, slate gray, and white albatross and is the largest of the mollymawks.
Buller's albatross or Buller's mollymawk, is a small mollymawk in the albatross family.
The Campbell albatross or Campbell mollymawk, is a medium-sized mollymawk in the albatross family. It breeds only on Campbell Island and the associated islet of Jeanette Marie, in a small New Zealand island group in the South Pacific. It is sometimes considered a subspecies of the black-browed albatross. It is a medium-sized black and white albatross with a pale yellow iris.
The Indian yellow-nosed albatross is a member of the albatross family, and is the smallest of the mollymawks. In 2004, BirdLife International split this species from the Atlantic yellow-nosed albatross; however Clements has not split it yet, and the SACC has not either, but recognises the need for a proposal.
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.
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.
The Tristan albatross is a large seabird from the albatross family. One of the great albatrosses of the genus Diomedea, it was only widely recognised as a full species in 1998.
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 of short-tailed albatross show they once lived there up to the Pleistocene, and occasional vagrants are found. Great albatrosses are among the largest of flying birds, with wingspans reaching up to 2.5–3.5 metres (8.2–11.5 ft) and bodies over 1 metre (3.3 ft) in length. The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species.
The white-chinned petrel also known as the Cape hen and shoemaker, is a large shearwater in the family Procellariidae. It ranges around the Southern Ocean as far north as southern Australia, Peru and Namibia, and breeds colonially on scattered islands. The white-chinned petrel was formerly considered to be conspecific with the spectacled petrel.
Gibson's Albatross, also known as the Auckland Islands wandering albatross or Gibson's wandering albatross, is a large seabird in the great albatross group of the albatross family. It is found principally in the Auckland Islands archipelago of New Zealand, foraging in the Tasman Sea, with most individuals nesting on Adams Island. The common name and trinomial commemorate John Douglas Gibson, an Australian amateur ornithologist who studied albatrosses off the coast of New South Wales for thirty years.
