Banggai Crow Corvus unicolor

An entirely black, short-tailed, pale-eyed crow confined to the island of Peleng in the Banggai Islands. Occurs in groups within canopy of montane forest. Tail just barely extends beyond wingtips when perched. Shorter-tailed and shorter-billed than Slender-billed Crow, and shows a pale eye, unlike that species. Voice also differs. Song is a “whee-kew-kew-kew,” with a rasping note starting the series and higher-pitched, ascending whistles following.
