Erect-crested Penguin
The erect-crested penguin (''Eudyptes sclateri'') is a penguin endemic to the New Zealand region and only breeds on the Bounty Islands, Bounty and Antipodes Islands. It has black upper parts, white underparts and a yellow eye stripe and crest. It spends the winter at sea and little is known about its biology and breeding habits. Populations are believed to have declined during the last few decades of the twentieth century, and the International Union for Conservation of Nature has listed it as being "Endangered species, endangered". Description This is a small-to-medium-sized, yellow-crested, black-and-white penguin, at and weighing . The male is slightly larger than the female and as in most crested penguins has a larger bill. It has bluish-black to jet black upper parts and white underparts, and a broad, bright yellow eyebrow-stripe which extends over the eye to form a short, erect crest. With a mean body mass in males of (sample size 22) and females of (sample size 22), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proclamation Island
Proclamation Island is a small rocky island west of Cape Batterbee and close east of the Aagaard Islands of Antarctica. Historic site The island was discovered by the British Australian New Zealand Antarctic Research Expedition (BANZARE), led by Douglas Mawson, 1929–1931, and so named, following the reading of a proclamation on its summit on 13 January 1930 claiming the area for The Crown, the British Crown. A cairn and commemorative plaque, plaque erected by Mawson at the time to commemorate the event has been designated a Historic Sites and Monuments in Antarctica, Historic Site or Monument (HSM 3) following a proposal by Australia to the Antarctic Treaty System, Antarctic Treaty Consultative Meeting.

Campbell Island, New Zealand
Campbell Island / Motu Ihupuku is an uninhabited subantarctic island of New Zealand, and the main island of the Campbell Island group. It covers of the group's , and is surrounded by numerous stacks, rocks and islets like Dent Island, Folly Island (or Folly Islands), Isle de Jeanette-Marie, and Jacquemart Island, the latter being the southernmost extremity of New Zealand. The island is mountainous, rising to over in the south. A long fiord, Perseverance Harbour, nearly bisects it, opening out to sea on the east coast. The island is listed with the New Zealand Outlying Islands. The island is an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all other outlying islands, other than the Solander Islands. It is the closest piece of land to the antipodal point of the United Kingdom, and Ireland, meaning that the furthest away city is Limerick, Ireland. Campbell Island is a UNESCO World Heritage Site. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eudyptes
The term crested penguin is the common name given collectively to species of penguins of the genus ''Eudyptes''. The exact number of species in the genus varies between four and seven depending on the authority, and a Chatham Islands species became extinct in recent centuries. All are black and white penguins with yellow crests, red bills and eyes, and are found on Subantarctic islands in the world's southern oceans. All lay two eggs, but raise only one young per breeding season; the first egg laid is substantially smaller than the second. Taxonomy The genus ''Eudyptes'' was introduced by the French ornithologist Louis Jean Pierre Vieillot in 1816; the name is derived from the Ancient Greek words ''eu'' meaning "fine", and ''dyptes'' meaning "diver". The type species was designated as the southern rockhopper penguin by George Robert Gray in 1840. Six extant species have been classically recognised, with the recent splitting of the rockhopper penguin increasing it to seven. Conver ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salvin's Albatross
Salvin's albatross (''Thalassarche salvini'') or Salvin's mollymawk, is a large seabird that breeds mainly on the Bounty Islands of New Zealand, with scant amounts on islands across the Southern Ocean. A medium-sized mollymawk, it was long considered to be a subspecies of the shy albatross. Taxonomy Mollymawks are a type of albatross that belong to the family Diomedeidae in 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 on the albatross are on the sides of the bill, unlike other tubenosed seabirds. 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 an energy rich food source for chicks ...

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, ...

Sympatry
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do not ...

Falkland Islands
The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833, but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands. British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
