Spotted
The Lesser Koa-finch was an extinct Hawaiian honeycreeper, formerly found on Hawaii Island. It was a large, robust finch with a heavy bill, characterized by its yellowish-green plumage and slightly smaller size than its relative.
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. Historically, it was identified by its large finch-like bill, yellowish-green plumage, and association with koa trees, where it would crack open pods for seeds.
When to spot
Last observed in 1896 and is considered extinct. It is no longer observable.
Both Koa-finch species were specialized seed-eaters, with bills perfectly adapted to crack open the tough pods of the native koa tree, a crucial food source.
