The erect-crested penguin (Eudyptes sclateri) is a penguin known only from New Zealand, where it breeds on the Bounty and Antipodes Islands, although previously also known from Campbell Island. It has black upper parts, white underparts and a yellow eye stripe and crest. It spends the winter at sea and little is known about its biology and breeding habits. Populations have declined during the last few decades of the twentieth century, and the International Union for Conservation of Nature has listed it as being "endangered".
