Sooty Shearwater
The sooty shearwater (''Ardenna grisea'') is a medium-large shearwater in the seabird family Procellariidae. In New Zealand, it is also known by its Māori name , and as muttonbird, like its relatives the wedge-tailed shearwater (''A. pacificus'') and the Australian short-tailed shearwater (''A. tenuirostris''). Taxonomy The sooty shearwater was formally described in 1789 by the German naturalist Johann Friedrich Gmelin under the binomial name ''Procellaria grisea''. The shearwater had been briefly described in 1777 by James Cook in the account of his second voyage to the Pacific, and in 1785 the English ornithologist John Latham had described a museum specimen. The sooty shearwater is now placed in the genus ''Ardenna'', that was introduced in 1853 by Ludwig Reichenbach. The genus name ''Ardenna'' was used to refer to a seabird by Italian naturalist Ulisse Aldrovandi in 1603, and the specific epithet ''grisea'' is medieval Latin for "grey". The species is considered to be mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Shag
The imperial shag or imperial cormorant (''Leucocarbo atriceps'') is a black and white cormorant native to southern South America, primarily in rocky coastal regions, but locally also at large inland lakes. Some taxonomic authorities, including the International Ornithologists' Union, place it in the genus ''Leucocarbo'', others in the genus ''Phalacrocorax''. It is also known as the blue-eyed shag, blue-eyed cormorant and by many other names, and is one of a larger group of cormorants called blue-eyed shags. The taxonomy is very complex, and several former subspecies are often considered separate species. Taxonomy The taxonomy is very complex and species-limits within this group remain unresolved. Some taxonomic authorities, including the International Ornithologists' Union, split the group into the species listed below. Others consider the all or part of the group conspecific. The following are considered part of this group: * Imperial shag, ''Leucocarbo (atriceps) atriceps'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magellanic Penguin
The Magellanic penguin (''Spheniscus magellanicus'') is a South American penguin, breeding in coastal Patagonia, including Argentina, Chile, and the Falkland Islands, with some migrating to Brazil and Uruguay, where they are occasionally seen as far north as Espirito Santo. Vagrants have been found in El Salvador, the Avian Island in Antarctica, Australia, and New Zealand. It is the most numerous of the ''Spheniscus'' penguins. Its nearest relatives are the African penguin, the Humboldt penguin, and the Galápagos penguins. The Magellanic penguin was named after Portuguese explorer Ferdinand Magellan, who spotted the birds in 1520. The species is listed as being of Least Concern by the IUCN. Description Magellanic penguins are medium-sized penguins which grow to be tall and weigh between . The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two black bands between the ...

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 pr ...

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 ...

Southern Rockhopper Penguin
The southern rockhopper penguin group (''Eudyptes chrysocome''), 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. Taxonomy In 1743 the English naturalist George Edwards included an illustration and a description of the southern 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. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the southern rockhopper penguin with the red-billed tropicbird in the genus ''Phaethon''. Linnaeus included a brief description, coined the binomial name ''Phaethon demersus'' and cited Edwards' work. The use of Linnaeus' binomial name was not adopted by later ornithologists, ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tussac Grass
''Poa flabellata'', commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. There are also two isolated records from the herbarium at the French Muséum national d'histoire naturelle for the Île Amsterdam in the Indian Ocean. It was introduced to Shetland, Scotland for basket making in 1844, and possibly as a source of fodder because of its ability to grow in hostile conditions.. It grows in dense clumps, usually about high (although they can be much taller), on wet coastal land and is a dominant feature of much of the landscape. Associated organisms The plant community dominated by ''P. flabellata'' is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
