![]() Rockhoppers are the most widespread crested penguins. Rockhopper penguin with chicks, New Island, Falkland Islands They can dive up to 330 feet (100 m) for many minutes at a time while searching for prey. Rockhopper penguins can be at sea for several days while hunting. Rockhopper penguins consume more krill than they do fish their diet changes during migration and as the seasons change. The rockhopper penguin's diet consists of krill and small crustaceans, which may include shrimp, crabs, lobsters or crayfish. ![]() They make nests and burrows in tall grasses called tussocks. Rockhopper penguins usually make their habitat in rocky shorelines. Eastern rockhopper penguins are mostly found breeding on Campbell Island in New Zealand, but their numbers have declined immensely. The southern rockhopper breeds on the Falkland Islands, Argentina and Chile, with breeding colonies around Cape Horn in South America, and Gough, Prince Edward, Marion, Crozet, Kerguelen, Heard, Macquarie, Campbell, Auckland and Antipodes Islands in the southern Indian Ocean. Northern rockhopper penguins breed in cool temperate climates including on the islands of Gough and Tristan da Cunha in the Atlantic Ocean and St. Rockhopper penguin skeleton in Manchester Museum Northern rockhopper penguin, Eudyptes (chrysocome) moseleyi.Eastern rockhopper penguin, Eudyptes (chrysocome) filholi.Southern rockhopper penguin, Eudyptes (chrysocome) chrysocome.The Falkland Islands are known to have one of the largest populations of southern rockhopper penguins. chrysocome, which may be referred to the true southern subspecies, reproduces at offshore islands in southern Chile, Argentina and at the Falkland Islands. filholi (eastern) is known to reproduce in the sub-Antarctic around the Prince Edward Islands, Crozet Islands, Kerguelen Islands, Heard Island, Macquarie Island and Campbell, Auckland and Antipodes Islands. Southern rockhopper penguins are split into two subspecies and they are defined by their location of reproduction. moseleyi (northern) seems to have occurred quickly, thus these behavioral changes are enough to isolate these taxa. The difference in mating signalsįound between the subspecies E. What separates rockhopper penguins into subspecies is their location of reproduction and reproductive behaviors. The yellow and black ‘hair’ they have on the top of their head is similar to that of the Macaroni penguin (Eudyptes chrysolophus). Due to the harsh rocky environment, they cannot slide on their bellies like most penguins, so they hop to get from one place to another, hence their name. Their orange beak is initially black, but as the penguins get older, their beaks turn orange. Although their yellow and black spiky feathers differentiate them from other penguins, rockhopper penguin chicks do not have them these feathers develop with age. Some characteristics that differentiate them from the other penguins are their red eyes, orange beak, pink webbed feet, and the yellow and black spiky feathers they have on their head. Like many penguins, rockhopper penguins have a white belly and the rest of their body is black. Males and females cannot be distinguished visually, so a DNA test is conducted by taking a feather from the bird to determine its gender. After reaching full growth, they are about 20 inches or 50 centimetres in height. Rockhopper penguins (Eudyptes chrysocome) are among the smaller species of penguin. Some consider all three as distinct species, some split the western and eastern forms into the southern rockhopper penguin and keep the northern rockhopper as distinct, while other experts consider all three potential varieties to be one species. Not all experts agree on the classification of these penguins. 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.
