Birdfinding.info ⇒ The Greater Amakihi is known only from the Wailuku River Valley west of Hilo. It was first collected on April 23, 1892 and last recorded in 1901 or 1902. During that decade of known existence it was apparently locally common, with up to twelve being seen in a day of field work, and at least 32 specimens collected overall.

Extinct. Formerly endemic to the Big Island of Hawaii.
It was known from wet lowland and foothill ohia forests between around 150 and 1,200 m elevation. Apparently, all documented records were from the Wailuku River Valley.
Identification
A medium-sized honeycreeper with a thin, slightly decurved, sharp-tipped bill, like that of an oriole. All plumages were predominantly dull-olive above and yellowish below, brightest on the face, throat, and chest.
