Eudyptes chrysocome
Southern Rockhopper Penguin
The Southern Rockhopper Penguin is a small, distinctive penguin with a black back, white belly, and bright yellow crest feathers above red eyes. Its robust red-orange beak and pink feet contrast with its sleek black and white plumage.
Males are slightly larger than females, with more pronounced crests. Juveniles lack the yellow crest, instead having a grayish-white face. The species does not exhibit seasonal plumage changes.

Southern Rockhopper Penguins inhabit rocky, coastal areas of subantarctic and temperate southern oceans. They breed on islands in the southern Atlantic, Indian, and Pacific Oceans, including the Falkland Islands and islands near southern Chile.
During non-breeding seasons, they disperse into surrounding waters, sometimes travelling hundreds of kilometres from their breeding sites.

Southern Rockhopper Penguins primarily feed on small marine creatures. Their diet consists mainly of krill, small fish, and squid.
They are pursuit divers, catching prey by swimming at high speeds and manoeuvring skilfully underwater, often diving to depths of 100 meters or more.
Southern Rockhopper Penguins are known for their remarkable hopping ability, using both feet to bound over rocky terrain. They are highly social, forming large breeding colonies.
These penguins are excellent swimmers, using their flippers to 'fly' underwater at speeds up to 25 km/h when foraging.
Southern Rockhopper Penguins are vocal birds, especially in their breeding colonies. Their calls include a loud, harsh 'caa-caa-caa' used for territorial defence and mate recognition.
During courtship, pairs engage in a duet of braying calls, often described as a donkey-like 'haw-haw-haw'.
Southern Rockhopper Penguins form monogamous pairs and return to the same breeding sites annually. The breeding season typically begins in October. Males arrive first to establish territories and prepare nests.
Nests are simple depressions in the ground, often lined with small stones and vegetation. Females usually lay two eggs, with the second egg being larger and more likely to hatch successfully.
Both parents take turns incubating the eggs for about 33 days. The chicks are brooded for about 25 days and fledge at 65-75 days old. After they fledge, the parents continue to feed them for several weeks.
The Southern Rockhopper Penguin typically lives for 10 years, with a maximum recorded lifespan of 29.4 years.
Like all birds, lifespan can be affected by factors including predation, habitat quality, disease, and access to food sources.
Southern Rockhopper Penguins are classified as Vulnerable due to population declines. Major threats include climate change, which affects food availability, and marine pollution.
Conservation efforts focus on protecting breeding sites and marine foraging areas, as well as monitoring population trends.

Main predators include fur seals, sea lions, and killer whales in the water, while skuas and gulls may prey on eggs and chicks on land.
