île De Croÿ
Île de Croÿ is an island under French jurisdiction. It is part of an archipelago known as the Kerguelen Islands, situated approximately 10 miles (16 kilometres) north-west of the main island. It is located at 48°38'19.3"S 68°37'18.6"E and currently has no permanent population. History Île de Croÿ was discovered in 1776 by Captain James Cook as part of his renowned nautical expedition through the southern hemisphere. It is the largest of five islands in a small group Cook named the 'Cloudy Isles', now known as Iles Nuageuses. Geography and Geology Île de Croÿ, at its highest peak, rises 1,699 feet (518 meters) above sea level. The island stretches 3.49 miles (5.61 kilometers) long between its furthermost points, and covers an area of approximately 6.2 square miles (16 square kilometres).The majority of the archipelago is the result of volcanic activity, as indicated by its high concentration of flood basalt and trachytic ignimbrite.

Black-browed Albatross
The black-browed albatross (''Thalassarche melanophris''), also known as the black-browed mollymawk,Robertson, C. J. R. (2003) is a large seabird of the albatross family Diomedeidae; it is the most widespread and common member of its family. Taxonomy Mollymawks are albatrosses in the family Diomedeidae and order Procellariiformes, which also includes shearwaters, fulmars, storm petrels, and diving petrels. These birds share certain identifying features. They have nasal passages that attach to the upper bill called naricorns, although the nostrils on the 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. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as being an energy-rich food source for chicks and also for the adults during their long flights. The albatross also has a salt gland ...

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 ...

Southern Rockhopper Penguin
The western rockhopper penguin (''Eudyptes chrysocome''), traditionally known as the southern rockhopper penguin, is a species of rockhopper penguin that is sometimes considered distinct from the northern rockhopper penguin. It occurs in subantarctic waters of the western Pacific and Indian Oceans, as well as around the southern coasts of South America. It was formerly considered to be conspecific with the eastern rockhopper penguin (''Eudyptes filholi''). Taxonomy In 1743 the English naturalist George Edwards (naturalist), George Edwards included an illustration and a description of the western rockhopper penguin in the first volume of his ''A Natural History of Uncommon Birds''. Edwards based his hand-coloured etching on a preserved specimen owned by Peter Collinson (botanist), Peter Collinson. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the 10th edition of Systema Naturae, tenth edition, he placed the western rockhopper penguin with th ...

Snowy 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; 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 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 bird and is also one of the most far-ranging birds. Some individual snowy albatrosses are known to circumnavigate the Southern Ocean three times in one year, covering more than . Taxonomy The taxonomic history of this species is long and complicated. The species was first de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Giant Petrel
The northern giant petrel (''Macronectes halli''), also known as Hall's giant petrel, is a large, predatory seabird of the southern oceans. Its range overlaps broadly with the range of the related southern giant petrel (''Macronectes giganteus''), albeit slightly further to the north. Taxonomy The northern giant petrel was species description, formally described in 1912 by the Australian born ornithologist Gregory Mathews as a subspecies of the southern giant petrel with the trinomial name ''Macronectes giganteus halli''. The specific epithet ''halli'' was chosen to honour the Australian ornithologist Robert Hall (ornithologist), Robert Hall who had described the birds breeding on the Kerguelen Islands. The northern giant petrel is now considered to be a separate species and has the binomial name ''Macronectes halli''. It is monotypic: no subspecies are recognised. The genus name combines the Ancient Greek ''makros'' meaning "great" and ''nēktēs'' meaning "swimmer". The name "pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Kerguelen Tern
The Kerguelen tern (''Sterna virgata'') is a tern of the southern hemisphere. This seabird mainly breeds colonially in the Kerguelen Islands, as its common name implies. However, smaller colonies are also found in the Prince Edward Islands (i.e. Prince Edward and Marion) and Crozet Islands. The total number of individuals is from 3,500 to 6,500 birds, although there is no recent data from the main colony at Kerguelen. These birds do not inhabit Kerguelen proper, instead nesting on islets free of feral cats. During bad weather, they are known to abandon their colonies. Kerguelen terns are among the least-ranging of all typical terns. They generally do not reach far into the seas near their breeding grounds. These birds eat fish and marine invertebrates, especially those found in beds of the seaweed Macrocystis spp. They sometimes also hunt insects on land and catch fish from rivers on Kerguelen. There are two subspecies In Taxonomy (biology), biological classificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 René 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 ...

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 ...

Gentoo Penguin
The gentoo penguin ( ) (''Pygoscelis papua'') is a penguin species (or possibly a species complex) in the genus ''Pygoscelis'', most closely related to the Adélie penguin (''P. adeliae'') and the chinstrap penguin (''P. antarcticus''). The earliest scientific description was made in 1781 by Johann Reinhold Forster with a type locality in the Falkland Islands. The species calls in a variety of ways, but the most frequently heard is a loud trumpeting, which the bird emits with its head thrown back. Names The application of "gentoo" to the penguin is unclear. '' Gentoo'' was an Anglo-Indian term to distinguish Hindus from Muslims. The English term may have originated from the Portuguese ''gentio'' ("pagan, gentile"). Some speculate that the white patch on the bird's head was thought to resemble a turban. It may also be a variation of another name for this bird, "Johnny penguin", with Johnny being the Spanish counterpart of and sounding vaguely like gentoo. The Johnny rook, a pr ...

Eaton's Pintail
Eaton's pintail (''Anas eatoni'') is a dabbling duck of the genus ''Anas''. It is also known as the southern pintail. The species is restricted to the island groups of Kerguelen and Crozet in the southern Indian Ocean. It resembles a small female northern pintail. It was named after the English explorer and naturalist Alfred Edwin Eaton. It is threatened by introduced species, particularly feral cats, which prey on it, particularly during the post-breeding molt, when it is unable to fly. Taxonomy While previously considered a subspecies of northern pintail, the Eaton’s pintail is much smaller (one female Eaton’s pintail weighed 450 g, while the mean mass of female northern pintails is 871 g) and the male Eaton's pintail is female-like in patterning, unlike the sexually dimorphic northern pintail.del Hoyo, J., N. Collar, and G. M. Kirwan (2020). Eaton's Pintail (Anas eatoni), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. ...
