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 petre ...

Peruvian Diving Petrel
The Peruvian diving petrel (''Pelecanoides garnotii'') (local name in Peru: potoyunco) is a small seabird that feeds in offshore waters in the Humboldt Current off Peru and Chile. Taxonomy The Peruvian diving petrel was formally described in 1828 by the French naturalists René Lesson and Prosper Garnot under the binomial name ''Puffinuria garnotti''. In his book ''Manuel d'ornithologie'' Lesson quotes the text of a description written by Garnot. The Peruvian diving petrel is now placed in the genus '' Pelecanoides'' was originally introduced in 1799 by the French naturalist Bernard Germain de Lacépède for the common diving petrel. Page numbering starts at one for each of the three sections. The species is monotypic: no subspecies are recognised. Description Peruvian diving petrel is in overall length. Like the rest of the diving petrels it is a nondescript bird, with a dark back and pale belly, and blue feet, and can be separated from the rest of its family only by differenc ...

Petrel
Petrels are tube-nosed seabirds in the bird order Procellariiformes. Description The common name does not indicate relationship beyond that point, as "petrels" occur in three of the four families within that group (all except the albatross family, Diomedeidae). Having a fossil record that was assumed to extend back at least 60 million years, the Procellariiformes was long considered to be among the older bird groupings, other than the ratites, with presumably distant ties to penguins and loons. However, recent research and fossil finds such as ''Vegavis'' show that the Galliformes (pheasants, grouse and relatives), and Anseriformes (ducks, geese) are still not fully resolved. Known species All the members of the order are exclusively pelagic in distribution—returning to land only to breed. The family Procellariidae is the main radiation of medium-sized true petrels, characterised by united nostrils with medium septum, and a long outer functional primary feather. It is dom ...

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 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 fisheries discards and carrion. Whilst agile swimmers and excellent in water, petrels have weak legs and can only shuffle on land, with the giant petrels of the genus Macronectes ...

Magellanic Diving Petrel
The Magellanic diving-petrel (''Pelecanoides magellani'') is a species of diving petrel, one of five very similar, small, auk-like petrels found exclusively in the southern oceans. It is one of the smaller species of diving-petrels, though size differences are seemingly indistinguishable between species unless seen up close. It is probably the least known of all five species. Taxonomy The Magellanic diving-petrel was formally described in 1912 by the Australian born ornithologist Gregory Mathews as a subspecies of the Peruvian diving-petrel with the trinomial name ''Pelecanoides garnotii magellani''. It is now considered as a separate species with the binomial name ''Pelecanoides magellani''. The genus name combines the Ancient Greek ''pelekan '' meaning "pelican" and "-oidēs" meaning "resembling". The specific epithet ''magellani'' refers to the Straits of Magellan. The species is monotypic: no subspecies are recognised. According to HBW, this species is more closely relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelecanoides Georgicus (South Georgian Diving-petrel) (8365384976)
The South Georgia diving petrel or Georgian diving-petrel (''Pelecanoides georgicus'') is one of five very similar small auk-like diving petrels of the southern oceans. It is native to the South Atlantic and islands of the southern Indian Ocean and south-eastern Australia. Taxonomy and nomenclature The American ornithologist Robert Cushman Murphy and the zoologist Francis Harper described the South Georgia diving petrel in 1916. Its specific name, ''georgicus,'' is derived from the South Georgia islands where they identified the species. Other common names include ''puffinure de Géorgie du Sud'' (French), ''Breitschnabel Lummensturmvogel'' (German), and ''potoyunco de Georgia'' (Spanish). A unique New Zealand population is now considered a separate species, the Whenua Hou diving petrel. Description The South Georgia diving petrel is a small, plump petrel, in length and weighing around . Its plumage is black above and dull white below, and it has a stubby black bill with pale b ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Prince Edward Islands
The Prince Edward Islands are two small uninhabited islands in the sub-Antarctic Indian Ocean that are part of South Africa. The islands are named Marion Island (named after Marc-Joseph Marion du Fresne, 1724–1772) and Prince Edward Island (named after Prince Edward, Duke of Kent and Strathearn, 1767–1820). The islands in the group have been declared Special Nature Reserves under the South African Environmental Management: Protected Areas Act, No. 57 of 2003, and activities on the islands are therefore restricted to research and conservation management. Further protection was granted when the area was declared a marine protected area in 2013. The only human inhabitants of the islands are the staff of a meteorological and biological research station run by the South African National Antarctic Programme on Marion Island. History The islands were discovered on 4 March 1663 by Barent Barentszoon Lam of the Dutch East India Company ship ''Maerseveen'' and were named ''Dina' ...

Kerguelen Islands
The Kerguelen Islands ( or ; in French commonly ' but officially ', ), also known as the Desolation Islands (' in French), are a group of islands in the sub-Antarctic constituting one of the two exposed parts of the Kerguelen Plateau, a large igneous province mostly submerged in the southern Indian Ocean. They are among the most isolated places on Earth, located more than from Madagascar. The islands, along with Adélie Land, the Crozet Islands, Amsterdam and Saint Paul islands, and France's Scattered Islands in the Indian Ocean, are part of the French Southern and Antarctic Lands and are administered as a separate district. The main island, Grande Terre, is in area, about three quarters of the size of Corsica, and is surrounded by a further 300 smaller islands and islets, forming an archipelago of . The climate is harsh and chilly with frequent high winds throughout the year. The surrounding seas are generally rough and they remain ice-free year-round. There are no indig ...

Crozet Islands
The Crozet Islands (french: Îles Crozet; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command Jules (Julien-Marie) Crozet landed on Île de la Possession, claiming the archipelago for France. The expedition continued east and landed in New Zealand, where Captain Marion and much of his crew were killed and cannibalized by Maori. Crozet survived the disaster, and successfully led the survivors back to their base in Mauritius. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heard Island And McDonald Islands
The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall size is in area and it has of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947. They contain Australia's only two active volcanoes. The summit of one, Mawson Peak, is higher than any mountain in all other Australian states or territories, except Dome Argus, Mount McClintock and Mount Menzies in the Australian Antarctic Territory. The islands are among the most remote places on Earth: They are located about southwest of Perth, southwest of Cape Leeuwin, Australia, southeast of South Africa, southeast of Madagascar, north of Antarctica, and southeast of the Kerguelen Islands (part of French Southern and Antarctic Lands).
