Subspecies
No subspecies.
Sometimes placed in a separate genus, Nesocorax. Relationships uncertain. Perhaps an ancient derivative of the "Slender-billed Crow (Corvus enca) complex", but differs fundamentally in bill structure and plumage texture. Possibly nearest to Piping Crow (Corvus typicus) and Banggai Crow (Corvus unicolor).
Similar Species
Large-billed Crow (Corvus macrorhynchos) which is much larger with more massive bill.
