Spotted
The Greater Koa-finch was an extinct Hawaiian honeycreeper, once endemic to Hawaii Island. It was a very large, powerful-billed finch with olive-green plumage, specialized in feeding on the seeds of the koa tree.
Where to spot
Historically endemic to the dry and mesic koa forests on the slopes of Mauna Kea and Hualālai on Hawaii Island.
How to spot
Observation is no longer possible. Historical records describe it as a quiet, deliberate feeder within koa trees, identified by its exceptionally large, powerful bill and olive-green plumage. Its feeding sounds would have been distinctive.
When to spot
Last observed in 1896 and is considered extinct. It is no longer observable.

It possessed one of the largest and most robust bills among all Hawaiian honeycreepers, a testament to its adaptation for cracking open the extremely tough seeds of koa pods.
