Justification of Red List category
This species is known from the Hawaiian island of Moloka`i, USA, but it has not been recorded since 1907 and is now Extinct. Predation and habitat destruction by invasive species were the major factors causing its extinction.
Population justification
None remain.
Trend justification
The species was last collected in 1907 and intensive searches in the subsequent few decades could find no sign of it (Richardson 1949).
Drepanis funerea was only ever seen in forest understorey on Moloka`i, Hawai`i, USA, although fossils are known from the adjacent Maui (James and Olson 1991).
It inhabited the understory of wet forests where it fed on nectar.
Its extinction was probably largely caused by the destruction of its understorey habitat by introduced cattle and deer, mosquito-borne diseases and predation by rats and mongooses (Greenway 1967, Hume 2017).
