Green-billed Coucal (Centropus chlororhynchos)


It looks rather like the much commoner Greater 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.


Endemic. Found locally in wet zone of south-western Sri Lanka, especially in Sinharaja Rain Forrest.


This is a monotypic species.
The scientific name is sometimes spelled chlororhynchus.


This coucal is found only in the forests of the wet zone, west, south-west and south of the main mountain massif, which it ascends to 2,500 feet, or perhaps higher.


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 - with those of several ither endemic forest birds - unless wise foresight reserves extensive forest sanctuaries in the wet zone.
