Why is the erect-crested penguin endangered?

Its population fell from roughly 230,000 breeding pairs in the late 1970s to about 150,000 mature individuals by 2017, a substantial decline that led the IUCN to list it as Endangered.

Where does the erect-crested penguin live?

It breeds exclusively on New Zealand's Bounty and Antipodes Islands, with vagrants occasionally recorded as far away as the Falkland Islands and Argentina.

Eudyptes sclateriEN— Endangered

The erect-crested penguin is a rare crested penguin that breeds only on New Zealand's remote Bounty and Antipodes Islands. Access restrictions and harsh island logistics mean much of its biology remains poorly studied even as its population has declined sharply since the 1970s.
