Péninsule Jeanne D'Arc
Péninsule Jeanne d'Arc, also known as Presqu'île Jeanne d'Arc, (Joan of Arc Peninsula in English) is a peninsula of Grande Terre, the main island of the subantarctic Kerguelen archipelago in the southern Indian Ocean. Description The peninsula occupies the south-eastern corner of Grande Terre, to which it is connected by the narrow, wide Haulage des Swains isthmus at its north-west end, and by the similarly narrow Haulage des Naufragés isthmus to Presqu'île Ronarc'h towards the eastern end of its north coast. It is about long from west to east and wide. Port Jeanne d'Arc is the site of an abandoned Norwegian whaling station at the western end of the peninsula's north coast that is subject to a cultural heritage conservation program. Important Bird Area The southern coast of the peninsula has been identified as a Important Bird Area (IBA) by BirdLife International because of its breeding seabirds. It consists largely of cliffs that rise steeply from the shore to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerguelen Topographic Map-fr
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 in ...

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 a ...

Important Bird Areas Of Kerguelen
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Landforms Of The Kerguelen Islands
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerguelen Shag
The Kerguelen shag (''Leucocarbo verrucosus'') is a species of cormorant endemic to the Kerguelen Islands in the southern Indian Ocean, one of the most isolated places on Earth. Many authorities consider it a subspecies of the imperial shag. Range and habitat This species nests on the coast of Grande Terre (the main island of the archipelago), on offshore islands, and on islands in the Golfe du Morbihan. It forages at sea throughout the archipelago, usually within of shore and especially in bays and inlets, though immatures have been seen rarely as far as . Reports from Heard Island and western Australia may be of ship-assisted birds. In the austral summer it feeds among kelp, sometimes at the bottom. Description The Kerguelen shag is long with a wingspan of , making it the smallest blue-eyed shag. The adult's upperparts, tail, and thighs are metallic greenish black; the underbody to the throat is white; and the wing linings are brown. Some individuals have white patches o ...

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 th ...

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 triglycerides ...

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: *''S. v. mercuri'' (Voisin, 1971) – Crozet and Pr ... [...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 distribution overlaps broadly, but is slightly north of, the similar southern giant petrel (''Macronectes giganteus''). Taxonomy The northern giant petrel was 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 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 "petrel" refers to the Biblical account of Saint Peter walking on water, ...

Sooty Albatross
The sooty albatross, dark-mantled sooty albatross or dark-mantled albatross,BirdLife International (2008b) (''Phoebetria fusca''), is a species of bird in the albatross family. They breed on sub-Antarctic islands and range at sea across the Southern Ocean from South America to Australia.Brooke, M. (2004) Taxonomy Sooty albatrosses are a type of albatross that belongs to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages which 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 7 and 9 horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides which is stored in the proventriculus.

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, and the 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 relatively larger bill. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle.It has a small eye and is good at seeing. 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 asho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 in Spanish and sounds vaguely like gentoo. The Johnny rook, a predator, is likely ...
