Aplonas corvina (lapsus) Aplonis corvinus (lapsus) Kittlitzia corvina (Kittlitz, 1833) Lamprothornis corvina Kittlitz, 1833 The Kosrae starling, also known as Kosrae Island starling,[1] and formerly as Kusaie Mountain starling, (Aplonis corvina) is an extinct bird from the family of starlings (Sturnidae).

The Kosrae starling is only known by five specimens which were obtained between December 1827 and January 1828 by the Kittlitz Expedition.

In 1880 an expedition led by Otto Finsch was unable to find this bird.

Another survey by the Whitney South Seas Expedition of the American Museum of Natural History in 1931 proved that this species was extinct.

Its extinction was most likely caused by rats which escaped from whaling vessels during the 19th century and became widespread on Kosrae.
