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), ... [...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.

Auckland Islands
The Auckland Islands ( Māori: ''Motu Maha'' "Many islands" or ''Maungahuka'' "Snowy mountains") are an archipelago of New Zealand, lying south of the South Island. The main Auckland Island, occupying , is surrounded by smaller Adams Island, Enderby Island, Disappointment Island, Ewing Island, Rose Island, Dundas Island, and Green Island, with a combined area of . The islands have no permanent human inhabitants. The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all the other outlying islands except the Solander Islands. Ecologically, the Auckland Islands form part of the Antipodes Subantarctic Islands tundra ecoregion. Along with other New Zealand Subantarctic Islands, they were designated a UNESCO World Heritage Site in 1998. Geography The Auckland Islands lie south of Stewart Island, and from the South ...

Birds Described In 1888
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbir ...

Eudyptes
''Eudyptes'' is a genus of penguins whose members are collectively called crested penguins. The exact number of species in the genus varies between four and eight 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 Pierre Vieillot in 1816; the name is derived from the Ancient Greek words meaning "fine", and meaning "diver". The type species was designated as the western rockhopper penguin by George Robert Gray in 1840. The genus contains eight exant species: * Macaroni penguin, ''Eudyptes chrysolophus'' * Royal penguin, ''Eudyptes schlegeli'' * Northern rockhopper penguin, ''Eudyptes moseleyi' ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting and conserving 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 Presidency of Richard Nixon#Environmental policy, 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 wher ...

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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

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, invasive species, and climate change. 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 ... [...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 a ...

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 ...
