Birdfinding.info ⇒  The Maui Nui Akialoa is known mainly from three specimens collected above Ko’ele from November 15 to 22, 1892.  The last universally accepted record was of a male in approximately the same location on January 9, 1894. There were additional sightings at Lana’i’hale during November 1892 and another credible, but uncertain sighting of a male sometime between 1911 and 1930.

Maui Nui Akialoa †

Akialoa lanaiensis

Extinct.  Formerly endemic to Lanai.  Subfossil remains have been discovered on Molokai—and thus known to have been present on Maui Nui (i.e., “Greater Maui”).

Identification

A very large honeycreeper with an extraordinarily long, scimitar-shaped bill.

Male was golden-olive above and yellowish below.

Females and immatures were dull-olive above and whitish below.

Notes

Monotypic species.  Formerly considered conspecific with Kauai, Oahu, and Lesser Akialoas, known collectively as the Akialoa (Hemignathus ellisianus).
