Eudyptes calauina is an extinct species of crested penguin that lived during the Late Pliocene. [1] It inhabited what is now central Chile.
The genus name Eudyptes derives from Ancient Greek, translating to "fine diver". The species name calauina derives from the Yaghan name for the rockhopper penguin (Eudyptes chrysocome). [1]
Eudyptes calauina specimens stem from the Horcon Formation in the Valparaiso Region of central Chile. [1] The extant crested penguin species do not inhabit central Chile. [1] [2]
Eudyptes calauina is larger than the extant crested penguins. [1] It is also larger than Megadyptes antipodes , Spheniscus chilensis and Spheniscus humboldti . [1] It is similar in size and proportions to Nucleornis insolitus, an extinct penguin species of the Early Pliocene in South Africa. [1]
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 found north of the Equator. 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.
The macaroni penguin 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 5.5 kg (12 lb) and are 70 cm (28 in) 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.
The erect-crested penguin is a penguin endemic to the New Zealand region and only breeds on the 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".
The Snares penguin, 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 50–70 cm (19.5–27.5 in) and a weight of 2.5–4 kg (5.5–8.8 lb). 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 Fiordland penguin, also known as the Fiordlandcrested penguin, 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.
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 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.
The rockhopper penguins are three closely related taxa of crested penguins that have been traditionally treated as a single species and are sometimes split into three species.
Flightless birds are birds that cannot fly. They have, through evolution, lost the ability to fly. There are over 60 extant species, including the well-known ratites and penguins. The smallest flightless bird is the Inaccessible Island rail. The largest flightless bird, which is also the largest living bird in general, is the common ostrich.
The banded penguins are penguins that belong to the genus Spheniscus. There are four living species, all with similar banded plumage-patterns. They are sometimes also known as "jack-ass penguins" due to their loud locator-calls sounding similar to a donkey braying. Common traits include a band of black that runs around their bodies bordering their black dorsal coloring, black beaks with a small vertical white band, distinct spots on their bellies, and a small patch of unfeathered or thinly feathered skin around their eyes and underdeveloped fluff sack that can be either white or pink. All members of this genus lay eggs and raise their young in nests situated in burrows or in natural depressions in the earth.
Inguza predemersus is an extinct species of penguin. It was formerly placed in the genus Spheniscus and presumed to be a close relative of the African penguin, but after its well-distinct tarsometatarsus was found, it was moved into its present monotypic genus. The known fossils specimens were found in Late Pliocene rocks in a quarry at Langebaanweg, South Africa, from about 5 million years ago.
The Chatham penguin, also known as the Chatham crested penguin, Chatham Islands penguin, or Warham's penguin, is an extinct species of crested penguin previously endemic to the Chatham Islands of New Zealand. It is known only from subfossil bones and probably became extinct within 150–200 years after Polynesians arrived in the Chatham Islands around 1500 CE.
The Hunter Island penguin is the former common name given to a number of subfossil penguin remains found in a Holocene Aboriginal midden at Stockyard Site on Hunter Island, in Bass Strait 5 km off the western end of the north coast of Tasmania, Australia. The remains were estimated by radiocarbon dating to be about 760 ± 70 years old and were used as basis to describe a new genus and species, Tasidyptes hunteri.
Tereingaornis moisleyi, also referred to as Moisley's penguin, is a genus and species of extinct penguin from the Middle Pliocene of New Zealand. It was slightly smaller than the extant Fiordland crested penguin. It was described by Ron Scarlett in 1983 from fossil material found by William Moisley near Te Reinga Falls on the Wairoa River, in the Hawke's Bay Region of the North Island. Another specimen was found later at Waihi Beach, Hāwera, on the South Taranaki Bight. The genus name Tereingaornis combines the name of the type locality with the Greek ornis ("bird"); the specific epithet honours the discoverer of the fossil.
Spheniscus muizoni is an extinct species of banded penguins that lived during the early Late Miocene in what is now Peru, South America. The species, the earliest member of the extant genus, was described in 2007 by Ursula B. Göhlich based on fossils found in the fossiliferous Pisco Formation of the Pisco Basin, southwestern Peru.
Spheniscus megaramphus is an extinct species of penguin that lived during the Late Miocene South America. It is notable for being the largest known species of banded penguin, along with having a proportionally large beak.
Spheniscus anglicus is an extinct species of banded penguin that lived during the Late Miocene in what is now Chile, South America. The species was described in 2015 by Richard D. Benson based on a fossil found in the Bahia Inglesa Formation in northern Chile.
Eudyptes atatu is an extinct species of crested penguin that lived during the Pliocene epoch around 3.2 million years ago. It is considered the first stem species of the crested penguin genus. Eudyptes atatu is thought to have inhabited what is now New Zealand. The bird's existence has been cited as evidence supporting the idea that penguins originated in Zealandia before spreading across the Southern Hempishere.
Spheniscus chilensis is an extinct species of penguin that lived during the Late Pliocene in Chile. The first fossil record of the penguin was discovered on the coast of Antofagasta in 1980, when coastal erosion exposed the first fossilized bone.
