Justification of Red List Category
This species was known from the island of Kosrae, Micronesia, but it is now Extinct due to overpredation by introduced rats. The last specimens were taken in 1828, and it was absent when the island was next visited in 1880.
Aplonis corvina was endemic to Kosrae, Caroline Islands, Federated States of Micronesia (Greenway 1967). It is only known from two specimens, both collected by Kittlitz in 1828 (Knox and Walters 1994), and both now in St Petersburg (Pratt et al. 1987). It was extinct by the time that Finsch visited the island in 1880 (Greenway 1967).
It inhabited mountain forests.
Its extinction was presumably a result of depredation by introduced rats, which were accidentally introduced by whalers and are abundant on the island.
