These birds are endemic to the Hawaiian Islands.Extinctions
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.
One species known as the Giant Amakihi known only from fossils, became extinct in prehistoric times, when Polynesian settlers deforested the lowlands for agriculture.Taxonomy
