African Penguin Facts & Biology
Discover how a pair of endangered seabirds established a mainland colony in Simon's Town in 1982.
African Penguin Biological Profile
Why Are There Penguins at Boulders Beach?
Historically, African Penguins nested on offshore islands to avoid terrestrial predators like leopards and wild dogs. In 1982, two breeding pairs established a nest on the mainland at Boulders Beach. The site offered protection from heavy sea swells due to ancient granite boulders and abundant anchovies in False Bay following commercial fishing restrictions.
Because human settlements surrounding Simon's Town provided a barrier against large land predators, the colony expanded rapidly from two pairs to over 2,000 birds today.
Why Are They Called 'Jackass Penguins'?
The African Penguin is famous for making a loud, donkey-like braying noise to communicate with mates and establish territory boundaries. This loud vocal call earned them the colloquial name 'Jackass Penguin'.
Each penguin has a unique pattern of black spots on its white chest, similar to a human fingerprint. Marine biologists use these spot patterns to identify individual birds without needing leg bands.
