''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. ==Systematics== (Sub)Genus ''Hemignathus sensu stricto'' - pointed or long and downcurved bills, insectivores or nectarivores.
