Hemignathus is a Hawaiian honeycreeper genus in the finch family, Fringillidae. These birds are endemic to the Hawaiian Islands.

Many of its species became extinct during the 19th and 20th centuries due to a combination of habitat destruction, introduced predators, and most importantly mosquito-borne diseases. Some others became extinct in prehistoric times, when Polynesian settlers deforested the lowlands for agriculture.

They have a wide variety of bill shapes and sizes; if the genus is broadly defined, this diversity is probably the largest of all bird genera living or extinct.


The genus Hemignathus is sometimes split into four distinct genera. While it is probably desirable to move at least some species to their own genera, many authorities are reluctant to do so at present due to the lack of comprehensive studies. Because half of the taxa are extinct, such studies are difficult.

(Sub)Genus Akialoa - long and downcurved bills, primarily nectarivores
