Sunda Coucal Centropus nigrorufus

Uncommon and localized Javan endemic, restricted to coastal marshes, mangroves, estuaries, and adjacent scrubby and grassy growth. Black overall, with bright red eyes and patchy rufous-and-black wings. Also note huge, heavy bill with a hooked tip. Not as vocal as other coucals; infrequently gives a monotonous series of hoots which averages faster than that of Greater Coucal. Forages on the ground and in dense vegetation, only occasionally emerging into the open.
