Maui Nui Akialoa
(but see text)
The Greater Akialoa was a large bird growing up to 19 cm long. Its bill took up to a third of the body length. The species had three forms, confined to Lanai, Oahu and Kauai respectively. It did not include the much smaller Hawaii Akialoa, which was considered a full species. The Lanai and Oahu forms are extinct, while there is a remote possibility that the Kaui form survives.
