オオバンケン Centropus sinensis

A large bird that resembles a cross between a crow and a pheasant. Largely black with distinctive rusty wings, glossy underparts, a long and heavy black tail, and deep red eyes. Juveniles are much duller with white bars on the tail and underparts and variable amounts of black streaks on the wings and upperparts. Common across a range of habitats except very dense forests. Similar to Lesser Coucal, but Greater Coucal is larger with a longer bill and red eyes. Adult Greater Coucals also lack the white streaks on the wings seen on Lesser Coucal. The call is a series of deep, resonant “oop-oop-oop” notes.
