The huia (Māori: [ˈhʉia]; Heteralocha acutirostris) was the largest species of New Zealand wattlebird, endemic to the North Island of New Zealand. Its extinction in the early 20th century had two primary causes. The first was rampant overhunting to procure huia skins for mounted specimens, which were in worldwide demand by museums and wealthy private collectors. Huia were also hunted to obtain their long, striking tail feathers for locally fashionable hat decorations. The second major cause of extinction was the widespread deforestation of the lowlands of the North Island by European settlers to create pasture for agriculture. Most of these forests were ancient, ecologically complex primary forests, and huia were unable to survive in regenerating secondary forests. The last confirmed sighting of a huia was on 28 December 1907 in the Tararua Ranges. Further credible sightings near Wellington were reported until 1922, and in Te Urewera National Park in the early 1960s.
