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' ...

Eudyptes Pachyrhynchus
The Fiordland penguin (''Eudyptes pachyrhynchus''), also known as the Fiordland crested penguin (in Māori, ''tawaki'' or pokotiwha), is a crested penguin species endemic to New Zealand. It currently breeds along the south-western coasts of New Zealand's South Island as well as on Stewart Island/Rakiura and its outlying islands. Because it originally ranged beyond Fiordland, it is sometimes referred to as the New Zealand crested penguin. It is occasionally found in Australia. Taxonomy The Fiordland crested penguin was described in 1845 by English zoologist George Robert Gray, its specific epithet derived from the Ancient Greek ''pachy-''/παχυ- "thick" and ''rhynchos''/ρύγχος "beak". It is one of the four to seven species in the genus ''Eudyptes'', the generic name derived from the Ancient Greek ''eu''/ευ "good" and ''dyptes''/δύπτης "diver". Description This species is a medium-sized, yellow-crested, black-and-white penguin, growing to approximately long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eudyptes Chrysocome
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 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. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the western rockhopper penguin with the red-billed tropicbird in the genus ''Phaethon''.

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 on its forehead. Its 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 larger beak, bill. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle. 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 ashore, before returning to the sea. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penguin
Penguins are a group of aquatic flightless birds from the family Spheniscidae () of the order Sphenisciformes (). They live almost exclusively in the Southern Hemisphere. Only one species, the Galápagos penguin, is equatorial, with a small portion of its population extending slightly north of the equator (within a quarter degree of latitude). Highly adapted for life in the ocean water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend about half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy pen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eudyptes Robustus
The Snares penguin (''Eudyptes robustus''; ), also known as the Snares crested penguin and the Snares Islands penguin, is a penguin from New Zealand. The species breeds on the Snares Islands, a group of islands off the southern coast of the South Island. It is a yellow-crested penguin, with a size of and a weight of . It has dark blue-black upper parts and white underparts. It has a bright yellow eyebrow-stripe which extends over the eye to form a drooping, bushy crest. It has bare pink skin at the base of its large red-brown bill. The species nests in colonies ranging in size from around 10 nests to around 1200, under forest cover or the open. The main colonies are located on North East Island; other colonies are established on Broughton Island as well as the rocky Western Chain. The Snares penguin's main prey is krill, supplemented by squid and small fish. The species is rated as vulnerable by the International Union for Conservation of Nature (IUCN) as its breeding rang ...

Eastern Rockhopper Penguin
The eastern rockhopper penguin (''Eudyptes filholi''), also known as the tawaki piki toka, is a crested penguin with yellow crest feathers. It was formerly treated as conspecific with the western rockhopper penguin with the name "southern rockhopper penguin" for the combined species. It is one of the smallest crested penguins and has distinctive pink margins around its bill. It breeds on islands in the Southern Indian and Pacific Oceans. Taxonomy The eastern rockhopper penguin was formally described in 1879 by the English-born New Zealand scientist Frederick Wollaston Hutton based on a specimen that had been collected on Campbell Island which lies south of New Zealand's South Island. Hutton coined the current binomial name ''Eudyptes filholi'' where the specific epithet was chosen to honour the French medical doctor and palaeontologist, Henri Filhol. The species was formerly treated as conspecific with the western rockhopper penguin with the English name "southern rock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Rockhopper Penguin
The northern rockhopper penguin, Moseley's rockhopper penguin, or Moseley's penguin (''Eudyptes moseleyi'') is a penguin species native to the southern Indian Ocean, Indian and Atlantic Oceans. It is described as distinct from the southern rockhopper penguin. A study published in 2009 showed that the population of the northern rockhopper had declined by 90% since the 1950s. For this reason, the northern rockhopper penguin is classified as Endangered species, endangered. Taxonomy The rockhopper penguins have been considered to consist of two species, northern and southern rockhopper penguin, since research published in 2006 demonstrated morphology (biology), morphological, vocal, and genetic differences between the two populations. molecular clock, Molecular datings suggest that the genetic divergence with the southern rockhopper penguin may have been caused by a vicariance, vicariant event caused by a shift in the position of the Subtropical Front during the Mid-Pleistocene Tran ...
