In 2019, an international team of researchers extracted mitochondrial DNA from subfossil bones discovered in sand dunes on the Chatham Islands. This research confirmed that until a few centuries ago a unique crested penguin species, Eudyptes warhami, existed on the Chatham Islands.

Undisturbed for millennia, the Chatham Islands were once teeming with wildlife. Although some species have been lost since human habitation, thankfully many endangered species have been revitalised in recent years due to conservation efforts.
