  • The African penguin, also known as the jackass penguin and black-footed penguin is a species of penguin, confined to southern African waters. It is also widely known as the "jackass" penguin for its donkey-like bray especially noted during breeding, although several related species of South American penguins produce a comparable sound. Like almost all species of penguins it is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Adults weigh on average 2.2–3.5 kg and are 60–70 cm tall. It has distinctive pink patches of skin above the eyes and a black facial mask; the body upperparts are black and sharply delineated from the white underparts, which are spotted and marked with a black band. This pink gland above their eyes helps them to cope with changing temperatures. When the temperature gets hotter, the body of the African penguin sends more blood to these glands to be cooled by the air surrounding it. This then causes the gland to turn a darker shade of pink. The African penguin is a pursuit diver and feeds primarily on fish and squid.
