What it is
The Hawaiʻi mamo (Drepanis pacifica) was a black honeycreeper with bright yellow feathers on the rump and thighs and a long, curved bill for drinking nectar. The International Union for Conservation of Nature lists it as Extinct.
Range
Forests of the island of Hawaiʻi.
What happened
Hawaiian bird catchers took its yellow feathers for royal cloaks, often releasing the birds. Later, shotgun hunting by collectors, forest clearing, mosquitoes carrying bird diseases and introduced mongooses finished it.
When / status
Last confirmed sighting in 1898.
Human role
Loss of forest, introduced mosquitoes and predators, and heavy hunting for feathers drove it to extinction.
