Rockhopper penguins employ different strategies and foraging behaviors depending on the climate and environment. Rockhopper penguin skeleton in Manchester Museum Dives typically last around 12h, but can be up to 15hrs, with penguins leaving the colony around dawn (04:00) and returning at dusk (19:00). Night dives are typically much shallower than day dives.

Females typically forage during the day in 11-12h trips consisting of many dives, but they will occasionally forage at night. One study showed they are known for going up to 157 km away from their colonies when foraging. When making foraging trips, rockhoppers typically leave and return to their colonies in groups. Rockhopper penguins employ different strategies according to their conditions. Influenced by factors such as sea ice abundance, prey availability, breeding stage, and seasonality, rockhopper penguins must be able to adapt their behavior to fit the current conditions. Rockhopper penguins are known to have complex foraging behaviors. Incubation lasts 35 days and their chicks are brooded for 26 days.

Two eggs are laid but only one is usually incubated. Their breeding season starts in September and ends in November. Their breeding colonies are located from sea level to cliff-tops and sometimes inland. BehaviourĪ chick on the Saunders Island in the Falkland Islands

This stands as the age record for rockhopper penguins, and possibly it was the oldest penguin known. These penguins feed on krill, squid, octopus, lantern fish, mollusks, plankton, cuttlefish, and mainly crustaceans.Ī rockhopper penguin, named Rocky, in Bergen Aquarium in Norway, lived to 29 years 4 months. Outside the breeding season, the birds can be found roaming the waters offshore their colonies. filholi breeds on the Prince Edward Islands, the Crozet Islands, the Kerguelen Islands, Heard Island, Macquarie Island, Campbell Island, the Auckland Islands and the Antipodes Islands. These include most significantly Isla de los Estados, the Ildefonso Islands, the Diego Ramírez Islands and Isla Noir. chrysocome which breeds on the Falkland Islands and on islands off Patagonia. About two-thirds of the global population belongs to E. The southern rockhopper penguin group has a global population of roughly 1 million pairs. schlegeli), which may just be a colour morph of the macaroni penguin.penguinĮudyptes chrysocome chrysocome colony on Saunders Island, Falkland Islands The rockhopper penguins are closely related to the macaroni penguin ( E. Therefore, northern birds are sometimes separated as E. The northern rockhopper penguin lives in a different water mass than the western and eastern rockhopper penguin, separated by the Subtropical Front, and they are genetically different.

Eudyptes chrysocome filholi, the eastern rockhopper penguin or Indopacific southern rockhopper penguin – breeds on subantarctic islands of the Indian and western Pacific oceans.

Eudyptes chrysocome chrysocome, the western rockhopper penguin or American southern rockhopper penguin – breeds around the southern tip of South America.

The subspecies recognized for the southern rockhopper penguin complex are: Still others consider all three distinct. Some split the northern subspecies ( moseleyi) from the southern forms ( chrysocome and filholi). Many taxonomists consider all three rockhopper penguin forms subspecies. The rockhopper penguin complex is confusing. It has slate-grey upper parts and has straight, bright yellow eyebrows ending in long yellowish plumes projecting sideways behind a red eye.

It reaches a length of 45–58 cm (18–23 in) and typically weighs 2–3.4 kg (4.4–7.5 lb), although there are records of exceptionally large rockhoppers weighing 4.5 kg (9.9 lb). This is the smallest yellow-crested, black-and-white penguin in the genus Eudyptes. Southern rockhopper penguin( Eudyptes chrysocome) displaying its distinctive crest
