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.

Yellow-eyed Penguin

Yellow-eyed Penguin, 56–78 cm, is one of the world's rarest penguins, endemic to southeastern New Zealand and sub-Antarctic islands. Distinctive yellow iris and yellow band behind the eye. Piscivore; dives to 120 m for blue cod and opalfish. Endangered; threatened by habitat loss, introduced predators, and fisheries bycatch.
