South Island takahe were thought to be extinct, with the last known specimens collected in 1898. However, careful surveys rediscovered this bird species in 1948 in the Murchison Mountains of South Island. South Island takahe are listed as endangered on the IUCN redlist. They have been the focus of major conservation and reintroduction efforts. South Island takahe populations have been established on 4 offshore islands where there are no invasive predators. Previously, hunting, loss of habitat, and introduced predators were the major factors contributing to population decline. Loss of habitat and introduced predators are still major factors, but additionally South Island takahe are threatened by lack of genetic diversity and the low fertility of these birds.
