A large, long-tailed bird of lowland primary forest on Mindoro with a brown back and belly, dark wings with brown-edged feathers, a dark tail with a bluish iridescence, and a black hood with some light streaking on the back of the neck. Note the strong curved bill. Similar to Philippine Coucal, but has a brown rather than black belly and is restricted to primary forest rather than more open habitats. Song is a descending series of very deep hoots.
