The Yellow-eyed Penguin (Megadyptes antipodes) is a penguin distributed only in southern New Zealand, as well as on the Auckland Islands and Campbell Island. In Māori it is called Hoiho and in English Yellow-eyed Penguin. The yellow-eyed penguin is the only recent representative of its genus. No subtypes are distinguished.
The yellow-eyed penguin, along with the Galapagos penguin and the thick-billed penguin, is one of the rarest penguin species. He is classified by the IUCN as endangered. The reason for the classification is not only the low number of 4,800 sexually mature individuals, but also the relatively small breeding area with relatively few breeding colonies. Exceptional events in this region can have a significant impact on the overall stock.  On the New Zealand South Island, for example, half of the breeding pairs died in 1986 and 1990, and in 2004 fifty percent of the young birds died of diphtheria-like respiratory disease.
