Procellaridae
The family (biology), family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prion (bird), prions, and the shearwaters. This family is part of the bird order (biology), order Procellariiformes (or tubenoses), which also includes the albatrosses and the storm petrels. The procellariids are the most numerous family of tubenoses, and the most diverse. They range in size from the giant petrels with a wingspan of around , that are almost as large as the albatrosses, to the diving petrels with a wingspan of around that are similar in size to the little auks or dovekies in the family Alcidae. Male and female birds are identical in appearance. The plumage color is generally dull, with blacks, whites, browns and grays. The birds feed on fish, squid and crustacea, with many also taking Discards, fisheries discards and carrion. Whilst agile swimmers and excellent in water, petrels have weak legs and can only shuffle o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gadfly Petrel
The gadfly petrels or ''Pterodroma'' are a genus of about 35 species of petrels, part of the seabird order Procellariiformes. The gadfly petrels are named for their speedy weaving flight, as if evading gadflies (horseflies). The flight action is also reflected in the name ''Pterodroma'', from Ancient Greek ''pteron'', "wing" and ''dromos'', "runner". The short, sturdy bills of these medium to large petrels are adapted for soft prey that they pick from the ocean surface. They have twisted intestines for digesting marine animals that have unusual biochemistries. Their complex wing and face marking are probably for interspecific recognition. These birds nest in colonies on islands and are pelagic when not breeding. One white egg is laid usually in a burrow or on open ground. They are nocturnal at the breeding colonies. While generally wide-ranging, most ''Pterodroma'' species are confined to a single ocean basin (e.g. Atlantic), and vagrancy is not as common amongst the genus as ...

Little Auk
The little auk or dovekie (''Alle alle'') is a small auk, the only member of the genus ''Alle''. ''Alle'' is the Sami name of the long-tailed duck; it is onomatopoeic and imitates the call of the drake duck. Linnaeus was not particularly familiar with the winter plumages of either the auk or the duck, and appears to have confused the two species. Other common names include rotch, rotche, and sea dove, although this last sometimes refers to a different auk, the Black Guillemot, instead. It breeds on islands in the high Arctic. There are two subspecies: ''A. a. alle'' breeds in Greenland, Novaya Zemlya and Svalbard, and ''A. a. polaris'' on Franz Josef Land. A small number of individuals breed on Little Diomede Island in the Bering Strait with additional breeding individuals thought to occur on King Island, St. Lawrence Island, St. Matthew Island and the Pribilof Islands in the Bering Sea. Morphology and behaviour This is the only Atlantic auk of its size, half the size of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Petrel
Giant petrels form a genus, ''Macronectes'', from the family Procellariidae, which consists of two species. They are the largest birds of this family. Both species are restricted to the Southern Hemisphere, and though their distributions overlap significantly, with both species breeding on the Prince Edward Islands, Crozet Islands, Kerguelen Islands, Macquarie Island, and South Georgia, many southern giant petrels nest farther south, with colonies as far south as Antarctica. Giant petrels are extremely aggressive predators and scavengers, inspiring another common name, the stinker. South Sea whalers used to call them gluttons. They are the only member of their family that is capable of walking on land. Taxonomy The genus ''Macronectes'' was introduced in 1905 by the American ornithologist Charles Wallace Richmond to accommodate what is now the southern giant petrel. It replaced the previous genus ''Ossifraga'' which was found to have been earlier applied to a different grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storm Petrel
Storm-petrel may refer to one of two bird families, both in the order Procellariiformes, once treated as the same family. The two families are: *Northern storm petrels (''Hydrobatidae'') are found in the Northern Hemisphere, although some species around the Equator dip into the south. * Southern storm-petrels (Oceanitidae) are found in all oceans, although only white-faced storm petrel The white-faced storm petrel (''Pelagodroma marina''), also known as white-faced petrel is a small seabird of the austral storm petrel family Oceanitidae. It is the only member of the monotypic genus ''Pelagodroma''. Description The white-faced ...

Albatross
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). 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'' (great albatrosses) have the longest wingspans of any extant birds, reaching up to . The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several spe ...

Procellariiformes
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,Warham, J. (1996). ''The Behaviour, Population, Biology and Physiology of the Petrels''. London: Academic Press, or more commonly all the families except the albatrosses.Brooke, 2004. They are almost exclusively pelagic (feeding in the open ocean), and have a cosmopolitan distribution across the world's oceans, with the highest diversity being around New Zealand. Procellariiforms are colonial, mostly nesting on remote, predator-free islands. The larger species nest on the surface, while most smaller species nest in natural cavities and burrows. They exhibit strong philopatry, returning to their natal colony to breed and returning to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Shearwater
Shearwaters are medium-sized long-winged seabirds in the petrel family Procellariidae 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 (or tubenoses), which also .... They have a global marine distribution, but are most common in temperate and cold waters, and are pelagic outside the breeding season. Description These Procellariiformes, tubenose birds fly with stiff wings and use a "shearing" flight technique (flying very close to the water and seemingly cutting or "shearing" the tips of waves) to move across wave fronts with the minimum of active flight. This technique gives the group its English name. Some small species, like the Manx shearwater are cruciform in flight, with their long wings held directly out from their bodies. Behaviour Movements Many shearwaters are long-distance migrants, perhaps most s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prion (bird)
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 ', meaning "saw", a reference of the serrated edges of the birds' saw-like bill. They are found in the Southern Ocean and breed on a number of subantarctic islands. Prions grow long, and have blue-grey upper parts and white underparts. Three species of prion have flattened bills with a fringe of lamellae that act as strainers for zooplankton.Maynard, B. J. (2003) All prions are marine and feed on small crustacea such as copepods, ostracods, decapods, and krill, as well as some fish such as myctophids and nototheniids. List of species * ''Pachyptila'' ** ''Pachyptila turtur'', fairy prion ** ''Pachyptila belcheri'', slender-billed prion ** ''Pachyptila crassirostris'', fulmar prion ** ''Pachyptila vittata'', broad-billed prion ** ...

Diving Petrel
The diving petrels form a genus, ''Pelecanoides'', of seabirds in the family Procellariidae. There are four very similar species of diving petrels, distinguished only by small differences in the coloration of their plumage, habitat, and bill construction. They are only found in the southern hemisphere. The diving petrels were formerly placed in their own family, the Pelecanoididae. Diving petrels are auk-like small petrels of the southern oceans. The resemblances with the auks are due to convergent evolution, since both families feed by pursuit diving, although some researchers have in the past suggested that the similarities are due to relatedness. Among the Procellariiformes the diving petrels are the family most adapted to life in the sea rather than flying over it, and are generally found closer inshore than other families in the order. Taxonomy The genus ''Pelecanoides'' was introduced in 1799 by the French naturalist Bernard Germain de Lacépède for the common diving pe ...
