List Of Birds Of Heard And McDonald Islands
This is a list of the birds of Heard Island and the adjacent McDonald Islands in the southern Indian Ocean. For other animals there, see List of non-avian fauna of Heard Island and McDonald Islands. The avifauna of Antarctica include a total of 47 species, of which 1 is endemic. This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of ''The Clements Checklist of Birds of the World'', 2022 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. The birds of Heard Island and McDonald Islands, a subantarctic Australian territory between Australia, Africa and Antarctica, are, whether breeders or visitors, almost all seabirds which find their food at sea in the waters of the surrounding Southern Ocean. An exception is the black-faced sheathbill, an opportunistic scavenger around seal and pengui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subantarctic Skua
The brown skua (''Stercorarius antarcticus''), also known as the Antarctic skua, subantarctic skua, southern great skua, southern skua, or hākoakoa (Māori), is a large seabird that breeds in the subantarctic and Antarctic zones and moves further north when not breeding. Its taxonomy is highly complex and a matter of dispute, with some splitting it into two or three species: Falkland skua (''S. antarcticus''), Tristan skua (''S. hamiltoni''), and subantarctic skua (''S. lönnbergi''). To further confuse, it hybridizes with both the south polar and Chilean skuas, and the entire group has been considered to be a subspecies of the great skua, a species otherwise restricted to the Northern Hemisphere. Diet It feeds on fish (often via kleptoparasitism), penguin chicks and other seabirds, small mammals, eggs and carrion. Description This is the heaviest species of skua and rivals the largest gulls, the great black-backed gull and glaucous gull, as the heaviest species in th ...

Long-line Fishing
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long ''main line'' with baited hooks attached at intervals via short branch lines called ''snoods'' or ''gangions''.Method and Apparatus for Long Line and Recreational Bait Fishing Patent application 20080202013. 28 August 2008. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the . This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can l ...

Wandering Albatross
The wandering albatross, snowy albatross, white-winged albatross or goonie (''Diomedea exulans'') is a large seabird from the family Diomedeidae, which has a circumpolar range in the Southern Ocean. It was the last species of albatross to be described, and was long considered the same species as the Tristan albatross and the Antipodean albatross. A few authors still consider them all subspecies of the same species. The SACC has a proposal on the table to split this species, and BirdLife International has already split it. Together with the Amsterdam albatross, it forms the wandering albatross species complex. The wandering 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 is one of the largest, best known, and most studied species of bird in the world. It has the greatest known wingspan of any living bird, and is also one of the most far-ranging birds. Some individual wandering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Albatross
Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains show they once occurred there and occasional vagrants are found. Albatrosses are among the largest of flying birds, and species of the genus ''Diomedea'' (great albatrosses) have the longest wingspans of any extant birds, reaching up to . The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species. Albatrosses are highly efficient in the air, using dynamic soaring and slope soaring to cover great distances with little exertion. They feed on squid, fish, and krill by either scavenging, surface seizing, or diving. Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several spe ...

Heard Shag
The Heard Island shag (''Leucocarbo nivalis''), or Heard Island cormorant, is a marine cormorant native to the Australian territory comprising the Heard and McDonald Islands in the Southern Ocean, about 4100 km south-west of Perth, Western Australia. Taxonomy The Heard Island shag is one of the blue-eyed shags, sometimes placed in the genus ''Leucocarbo'', and a subspecies of the imperial shag. Others place it in the genus Phalacrocorax. It is now usually considered to be a full species. Distribution and habitat The Heard Island shag is restricted to the subantarctic Heard and McDonald Islands, and is only known to breed on Heard Island. Apart from breeding and roosting, its habitat is marine. Description The Heard Island shag has largely black upperparts and white underparts. The cheeks and ear-coverts are white; there are white bars on the wings, a black, recurved crest over the forehead, and pink feet.Marchant & Higgins (1991), p.854. A breeding adult has a pair of ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King Penguin
The king penguin (''Aptenodytes patagonicus'') is the second largest species of penguin, smaller, but somewhat similar in appearance to the emperor penguin. There are two subspecies: ''A. p. patagonicus'' and ''A. p. halli''; ''patagonicus'' is found in the South Atlantic and ''halli'' in the South Indian Ocean (at the Kerguelen Islands, Crozet Island, Prince Edward Islands and Heard Island and McDonald Islands) and at Macquarie Island. King penguins mainly eat lanternfish, squid and krill. On foraging trips, king penguins repeatedly dive to over , and have been recorded at depths greater than . Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal and the orca. King penguins breed on the Subantarctic islands at the northern reaches of Antarctica, South Georgia, and other temperate islands of the region. King penguins also live on Macquarie Island in the Southern Ocean. At one time, these birds were exploited commercially for t ...

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 ...

Eastern Rockhopper Penguin
The eastern rockhopper penguin (''Eudyptes chrysocome filholi'') is a crested penguin with yellow crest feathers. It is a subspecies of the southern rockhopper penguin (''Eudyptes chrysocome'') found in subantarctic regions and the Indian Ocean. It is one of the smallest crested penguins and has distinctive pink margins around its bill. Description The eastern rockhopper penguin is a small, crested penguin with a black back and throat, a white belly and pink feet. This seabird measures approximately 45–55 cm in length, and weighs 2.2–4.3 kg. It has a thin yellow stripe that stretches from its lower forehead, over its red eye and splits into crest feathers at the back of its head. The crest feathers are composed of long, thin, spiky yellow feathers on either side of the penguin's head and they are joined by shorter black feathers. Rockhopper penguins have an orange-brown bill and the eastern rockhopper penguin has distinctive pink margins around the bill. Males an ...
