About These Birds
African Penguin
The African penguin is the only penguin species native to the African continent, also called the jackass penguin for its donkey-like braying call. Their population has plummeted over 95% since pre-industrial times due to egg collection, oil spills, and competition with commercial fisheries for sardine and anchovy stocks.
Northern Rockhopper Penguin
Northern Rockhopper Penguin, 45–58 cm, breeds on Tristan da Cunha and Gough Island in the South Atlantic and Amsterdam Island in the Indian Ocean. Distinctive yellow and black crest, red bill, red eyes. Krill and fish feeder. Endangered; population has declined dramatically due to ocean warming and food shortages.
