Auckland Island

Pig

The Auckland Island Pig is a feral breed of domestic pig (Sus scrofa) found on subantarctic Auckland Island, New Zealand. Various introductions of pigs were made to the uninhabited island as a source of food for stranded sailors or visiting whalers, the first in 1807 with further liberations in 1840, 1842 and the 1890s. By the end of the 19th century the island held a thriving population of pigs of mixed origin which was largely undisturbed until the late 20th century, producing a distinctive breed.
