43 cm in length.
Slightly smaller than the Common Coucal, from which it may at once be distinguished by its leg, like-green beak; its wings, too, are much darker chestnut, and the sheen on the head and neck is purple, not blue. Sexes alike.

A very shy and elusive bird, it is far better known by its calls than by sight but, wherever the wet-zone forests have been spared the axe, it is still fairly common; its range, however, is rapidly dwindling and as it shows no sign of being able to adjust itself to new conditions, there can be no doubt that its days will soon be numbered - unless wise foresight reserves extensive forest sanctuaries in the wet zone. 

Undisturbed forests. Associated with bamboo and cane rushes. Breeding ground is in Low Country wet zones & wet foothills. More often heard than seen.
