The Hawaiian Goose or Nēnē, Branta sanvicensis, is a species of goose endemic to the Hawaiian Islands. It shares a recent common ancestor with Branta canadensis, the Canada Goose. The official bird of the State of Hawaiʻi, the Nēnē is exclusively found in the wild of the islands of Maui, Kauaʻi and Hawaiʻi. A larger, extinct and possibly flightless species, the Nēnē-nui (Branta hylobadistes), was present in prehistoric times on Maui; related, but hitherto undescribed forms also occurred on Kauaʻi and Oʻahu; there was also a gigantic, flightless relative on the island of Hawaiʻi.
