The prions or whalebirds are small petrels in the genera Pachyptila and Halobaena. They form one of the four groups within the Procellariidae along with the gadfly petrels, shearwaters and fulmarine petrels. The name comes from the Greek priōn, meaning "saw", a reference of the serrated edges of the birds' saw-like bill.
Pachyptila is a genus of seabirds in the family Procellariidae and the order Procellariiformes. The members of this genus and the blue petrel form a sub-group called prions. They range throughout the southern hemisphere, often in the much cooler higher latitudes. Three species, the broad-billed prion, the Antarctic prion and the fairy prion, range into the subtropics.
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 Chatham albatross, also known as the Chatham mollymawk or Chatham Island mollymawk, is a medium-sized black-and-white albatross which breeds only on The Pyramid, a large rock stack in the Chatham Islands, New Zealand (Aotearoa). It is sometimes treated as a subspecies of the shy albatross Thalassarche cauta. It is the smallest of the shy albatross group.
The Antarctic petrel is a boldly marked dark brown and white petrel, found in Antarctica, most commonly in the Ross and Weddell Seas. They eat Antarctic krill, fish, and small squid. They feed while swimming but can dive from both the surface and the air.
The southern giant petrel, also known as the Antarctic giant petrel, giant fulmar, stinker, and stinkpot, is a large seabird of the southern oceans. Its distribution overlaps broadly with the similar northern giant petrel, though it overall is centered slightly further south. Adults of the two species can be distinguished by the colour of their bill-tip: greenish in the southern and reddish in the northern.
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.
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.
The snow petrel is the only member of the genus Pagodroma. It is one of only three birds that have been seen at the Geographic South Pole, along with the Antarctic petrel and the south polar skua, which has the most southerly breeding sites of any bird, inland in Antarctica.
The fairy prion is a small seabird with the standard prion plumage of blue-grey upperparts with a prominent dark "M" marking and white underneath. The sexes are alike. It is a small prion which frequents the low subantarctic and subtropic seas.
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.
The broad-billed prion is a small pelagic seabird in the shearwater and petrel family, Procellariidae. It is the largest prion, with grey upperparts plumage, and white underparts. The sexes are alike. It ranges from the southeast Atlantic to New Zealand mainly near the Antarctic Convergence. In the south Atlantic it breeds on Tristan da Cunha and Gough Island; in the south Pacific it breeds on islands off the south coast of South Island, New Zealand and on the Chatham Islands. It has many other names that have been used such as blue-billed dove-petrel, broad-billed dove-petrel, long-billed prion, common prion, icebird, and whalebird.
The Antarctic prion also known as the dove prion, or totorore in Māori, is the largest of the prions, a genus of small petrels of the Southern Ocean.
The slender-billed prion or thin-billed prion, is a species of petrel, a seabird in the family Procellariidae. It is found in the southern oceans.
The fulmar prion is a species of seabird in the family Procellariidae, found in the southern oceans.
Salvin's prion, also known as the medium-billed prion, is a species of seabird in the petrel family Procellariidae.
The grey petrel, also called the brown petrel, pediunker or grey shearwater is a species of seabird in the Procellariidae, or petrel family. It is pelagic and occurs in the open seas of the Southern Hemisphere, mainly between 32°S and 58°S.
