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 ...

Eudyptes Chrysocome
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, ...

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 ...

Penguin
Penguins (order (biology), order List of Sphenisciformes by population, Sphenisciformes , family (biology), family Spheniscidae ) are a group of Water bird, aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have Countershading, 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 it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly 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 penguin, little blue penguin (''Eudyptula minor''), also known as the fairy penguin, whic ...

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, and the 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 relatively larger bill. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle.It has a small eye and is good at seeing. 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 asho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snares Penguin
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 range ... [...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 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. Taxonomy The rockhopper penguins have been considered to consist of two species, northern and southern rockhopper penguin, since research published in 2006 demonstrated morphological, vocal, and genetic differences between the two populations. Molecular datings suggest that the genetic divergence with the southern rockhopper penguin may have been caused by a vicariant event caused by a shift in the position of the Subtropical Front during the mid-Pleistocene climate transition.
