Scissor-billed koa finch Scissor-billed koa finch The scissor-billed koa finch, ("Rhodacanthis forfex") or scissor finch is an extinct species of Hawaiian honeycreeper. Of the four species in the genus "Rhodacanthis", the scissor-billed koa finch and the primitive koa finch became extinct before the arrival of the first Europeans to Hawaii in 1778. It was endemic to the islands of Maui and Kauai in the Hawaiian Islands. The scissor-billed koa finch was a granivore, that, like the other members of its genus, had a bill adapted to eat the hard seeds and pods of legumes.

Due to its early extinction, very little is known about this species. It is only known from fossil remains. Other Hawaiian honeycreepers are known to have become extinct or very rare due to habitat loss, introduced predators and avian diseases. It is possible the extinction of the scissor-billed koa finch also involved these factors.
