About These Birds

Erect-crested Penguin

Erect-crested Penguin, 67–70 cm, breeds only on Bounty and Antipodes Islands southeast of New Zealand. Distinctive erect, brush-like yellow crest standing upright from eye to crown. Forages at sea for fish and squid; breeding biology poorly known due to remote location. Endangered; declining.

King Penguin

The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
