![]() ![]() The flippers are blue-black on the upper surface with a white trailing edge, and mainly white underneath with a black tip and leading edge. The most striking feature is the yellow crest that arises from a patch on the centre of the forehead, and extends horizontally backwards to the nape. The black plumage has a bluish sheen when new and brownish when old. The head, chin, throat, and upper parts are black and sharply demarcated against the white under parts. The wing, from the shoulder to the tip, is around 20.4 cm (8.0 in) and the tail is 9–10 cm (3.5–3.9 in) long. Among standard measurements, the thick bill (from the gape) measures 7 to 8 cm (2.8 to 3.1 in), the culmen being around a centimetre less. Males average from 3.3 kg (7 lb) after incubating, or 3.7 kg (8 lb) after moult to 6.4 kg (14 lb) before moult, while females average 3.2 kg (7 lb) after to 5.7 kg (13 lb) before moult. An adult bird has an average length of around 70 cm (28 in) the weight varies markedly depending on time of year and sex. The macaroni penguin is a large, crested penguin, similar in appearance to other members of the genus Eudyptes. Description A skeleton on display in Manchester Museum Showing the conspicuous orange and yellow crests chrysocome filholi) has been reported at Heard and Marion Islands, with three hybrid subspecies recorded there by a 1987–88 Australian National Antarctic Research Expedition. Interbreeding with the Indo-Pacific subspecies of the southern rockhopper penguin ( E. The two species are very similar in appearance the royal penguin has a white face instead of the usually black face of the macaroni penguin. The two have generally been considered different species, but the close similarities of their DNA sequences has led some, such as Australian ornithologists Les Christidis and Walter Boles, to treat the royal penguin as a subspecies of the macaroni penguin. Molecular clock evidence using DNA suggests the macaroni penguin diverged from its closest relative, the royal penguin ( Eudyptes schlegeli), around 1.5 million years ago. It is similar to the then fashionable Macaroni. English sailors apparently named the species for its conspicuous yellow crest. ![]() The common name was recorded from the early 19th century in the Falkland Islands. The specific name chrysolophus is derived from the Greek words chryse "golden", and lophos "crest". The genus name is derived from the Ancient Greek words eu "good", and dyptes "diver". It is one of six or so species in the genus Eudyptes, collectively known as crested penguins. The macaroni penguin was described from the Falkland Islands in 1837 by German naturalist Johann Friedrich von Brandt. Widespread declines in populations have been recorded since the mid-1970s and their conservation status is classified as vulnerable. With about 18 million individuals, the macaroni penguin is the most numerous penguin species. After spending the summer breeding, penguins disperse into the oceans for six months a 2009 study found that macaroni penguins from Kerguelen travelled over 10,000 km (6,200 mi) in the central Indian Ocean. Numbering up to 100,000 individuals, the breeding colonies of the macaroni penguin are among the largest and densest of all penguin species. These birds moult once a year, spending about three to four weeks ashore, before returning to the sea. 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. Like all penguins, it is flightless, with a streamlined body and wings stiffened and flattened into flippers for a marine lifestyle. The male and female are similar in appearance the male is slightly larger and stronger with a relatively larger bill. Adults weigh on average 5.5 kg (12 lb) and are 70 cm (28 in) in length. Its face and upperparts are black and sharply delineated from the white underparts. It bears a distinctive yellow crest that resembles a hairdo consisting of macaroni, from which its name is derived. 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. The macaroni penguin ( Eudyptes chrysolophus) is a species of penguin found from the Subantarctic to the Antarctic Peninsula. ![]()
