The African Penguin, also known as the Jackass Penguin (after its donkey-like braying call), is found on the south-western coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. The largest colony is on Dyer Island, near Kleinbaai. The only penguin colonies still in existence on the African mainland are near Cape Town at Boulders Beach in Simon’s town and Stony Point in Betty’s Bay. African Penguins grow to 50 centimeters tall and weigh between 2 and 4 kilograms. They have a black stripe and black spots on the chest, the spots being unique for every penguin, like human fingerprints.
