テ四es Nuageuses
The テ四es Nuageuses (Cloudy Islands in English, named so because of their climate) comprise a group of small islands that are part of the Kerguelen archipelago, a French territory in the southern Indian Ocean. They are an important breeding spot for seabirds, especially penguins and albatrosses, and for fur seals. The islands are free of introduced species and are thus covered in dense subantarctic vegetation up to about 200 m. Human visitors are rare.BirdLife International. (2012). Important Bird Areas factsheet: テ四es Nuageuses and テ四e Clugny. Downloaded from http://www.birdlife.org on 2012-01-20. Geography The group is located in the northwestern area of the archipelago. It lies about north-west, across the Jean-Baptiste Charcot Channel, from the tip of the Loranchet Peninsula, the northernmost extension of Grande Terre, the principal island of the Kerguelens. The islands are of volcanic origin. The main islands of the Nuageuses are テ四e de Croテソ, テ四e du Rolan ...

Pテゥninsule Loranchet
The Pテゥninsule Loranchet, also known as Presqu'テョle Loranchet, (Loranchet Peninsula in English) is a peninsula of Grande Terre, the main island of the subantarctic Kerguelen Islands, Kerguelen archipelago in the southern Indian Ocean. Description The peninsula occupies the north-western corner of Grande Terre and is named after Jean Loranchet, the first officer of Raymond Rallier du Baty窶冱 second Kerguelen survey expedition in 1913. It has a rugged, mountainous interior, with altitudes exceeding 500 m and a coastline of steep cliffs deeply incised by fjords. It is some 50 km long with a width of up to 20 km. As with most of Grande Terre, it is infested with introduced species, introduced feral cats, rats and rabbits. Human visitation is infrequent. Important Bird Area The northern end of the peninsula, and the northernmost part of Grande Terre, extending northwards from the head of the Baie de la Dauphine, has been identified as a 60 km2 Important Bird Area ...

James Cook
Captain (Royal Navy), Captain James Cook (7 November 1728 窶 14 February 1779) was a British Royal Navy officer, explorer, and cartographer famous for his three voyages of exploration to the Pacific and Southern Oceans, conducted between 1768 and 1779. He completed the first recorded circumnavigation of the main islands of New Zealand and was the first known European to visit the eastern coastline of Australia and the Hawaiian Islands. Cook joined the British merchant navy as a teenager before enlisting in the Royal Navy in 1755. He served during the Seven Years' War, and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the Battle of the Plains of Abraham, siege of Quebec. In the 1760s, he mapped the coastline of Newfoundland (island), Newfoundland and made important astronomical observations which brought him to the attention of the Admiralty (United Kingdom), Admiralty and the Royal Society. This acclaim came at a crucial moment in Brit ...

White-chinned Petrel
The white-chinned petrel (''Procellaria aequinoctialis'') 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 (''Procellaria conspicillata''). Taxonomy In 1747 the English naturalist George Edwards included an illustration and a description of the white-chinned petrel in the second volume of his ''A Natural History of Uncommon Birds''. He used the English name "The great Black Peteril" and based his hand-coloured etching on a preserved specimen that had been brought to London. He believed that it had been collected near the Cape of Good Hope. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the white-chinned petrel with the other petrels in the ...

Kerguelen Petrel
The Kerguelen petrel (''Aphrodroma brevirostris'') is a small (36 cm long) slate-grey seabird in the family Procellariidae. It is the only species placed in the genus ''Aphrodroma''. It is a pelagic, circumpolar seabird of the Southern Ocean. It breeds on islands in the southern Atlantic and Indian Oceans. Taxonomy The Kerguelen petrel was formally described in 1831 by the French naturalist Renテゥ Lesson. He placed it in the genus ''Procellaria'' that had been erected for the petrels by Carl Linnaeus in 1758 and coined the binomial name ''Procellaria brevirostris''. The Kerguelen petrel was formerly included with the gadfly petrels in the genus '' Pterodroma'' and later in the monotypic genre ''Lugensa'' but is now placed in the genus ''Aphrodroma'' that was introduced for the Kerguelen petrel by Storrs L. Olson in 2000. The name ''Aphrodroma'' combines the Ancient Greek ''aphros'' meaning "sea foam" with ''-dromos'' meaning "-racer".The specific epithet ''brevirostris'' is ...

Antarctic Prion
The Antarctic prion (''Pachyptila desolata'') also known as the dove prion, or totorore in Mト{ri, is the largest of the prions, a genus of small petrels of the Southern Ocean. Taxonomy The Antarctic prion was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria desolata''. Gmelin based his description on the "brown-banded petrel" that had been described in 1785 by the English ornithologist John Latham from a specimen supplied by the naturalist Joseph Banks that had been collected on the "Isle of Desolation", now the Kerguelen Islands. The Antarctic prion is now one of seven prions placed in the genus ''Pachyptila'' that was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The genus name combines the Ancient Greek ''pakhus '' meaning "dense" or "thic ...

Light-mantled Albatross
The light-mantled albatross (''Phoebetria palpebrata'') also known as the grey-mantled albatross or the light-mantled sooty albatross, is a small albatross in the genus ''Phoebetria'', which it shares with the sooty albatross. The light-mantled albatross was first described as ''Phoebetria palpebrata'' by Johann Reinhold Forster, in 1785, based on a specimen from south of the Cape of Good Hope. Physiology Light-mantled albatrosses share some identifying features with other Procellariiformes. They have nasal tubes on the upper bill called naricorns, though with albatrosses these are on the sides of the upper mandible rather than the top. They also have a salt gland above the nasal passage which excretes a concentrated saline solution to maintain osmotic balance, due to the amount of seawater imbibed. The bills of the Procellariiformes are unique in that they are covered with from seven to nine horny plates. These birds produce a stomach oil made up of wax esters and triglyceride ...

Wandering Albatross
The snowy albatross (''Diomedea exulans''), also known as the wandering albatross, white-winged albatross, or goonie, is a large seabird from the family Diomedeidae Albatrosses, of the biological family (biology), family Diomedeidae, are large seabirds related to the procellariidae, procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the So ...; they have a circumpolar range in the Southern Ocean. It is the largest 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 Cryptic species complex, species complex, which some began referring to more recently as "snowy". The snowy albatross is one of the two largest members of the genus ''Diomedea'' (the great albatrosses), being similar in size to the southern royal albatross. It has the greatest known wingspan of any living bi ...

Indian Yellow-nosed Albatross
The Indian yellow-nosed albatross (''Thalassarche carteri'') is a member of the albatross family (biology), 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 South American Classification Committee, SACC has not either, but recognises the need for a proposal. Taxonomy Mollymawks are a type of albatross that belong to the family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. They have nasal passages called naricorns attached to the upper bill. The bills of Procellariiformes are unique in that they are split into between seven and nine horny plates. They make a stomach oil made of wax esters and triglycerides that is stored in the proventriculus. This is used against predators and as an energy rich food source for chicks and for the adults dur ...

Grey-headed Albatross
The grey-headed albatross (''Thalassarche chrysostoma'') 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. Taxonomy Mollymawks are a type of albatross that belong to the family Diomedeidae from the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils of an albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against ...

Macaroni Penguin
The macaroni penguin (''Eudyptes chrysolophus'') is a species of penguin found from the Subantarctic to the Antarctic Peninsula. One of six species of crested penguin, it is very closely related to the royal penguin, and some authorities consider the two to be a single species. It bears a distinctive yellow crest on its forehead. Its face and upperparts are black and sharply delineated from the white underparts. Adults weigh on average and are in length. The male and female are similar in appearance; the male is slightly larger and stronger with a larger beak, bill. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle. Its diet consists of a variety of crustaceans, mainly krill, as well as small fish and cephalopods; the species consumes more marine life annually than any other species of seabird. These birds moult once a year, spending about three to four weeks ashore, before returning to the sea. ...

Northern Rockhopper Penguin
The northern rockhopper penguin, Moseley's rockhopper penguin, or Moseley's penguin (''Eudyptes moseleyi'') is a penguin species native to the southern Indian Ocean, Indian and Atlantic Oceans. It is described as distinct from the southern rockhopper penguin. A study published in 2009 showed that the population of the northern rockhopper had declined by 90% since the 1950s. For this reason, the northern rockhopper penguin is classified as Endangered species, endangered. Taxonomy The rockhopper penguins have been considered to consist of two species, northern and southern rockhopper penguin, since research published in 2006 demonstrated morphology (biology), morphological, vocal, and genetic differences between the two populations. molecular clock, Molecular datings suggest that the genetic divergence with the southern rockhopper penguin may have been caused by a vicariance, vicariant event caused by a shift in the position of the Subtropical Front during the Mid-Pleistocene Tran ...
