The greater coucal or crow pheasant, is a large non-parasitic member of the cuckoo order of birds, the Cuculiformes. A widespread resident in the Indian Subcontinent and Southeast Asia, it is divided into several subspecies, some being treated as full species. They are large, crow-like with a long tail and coppery brown wings and found in a wide range of habitats from jungle to cultivation and urban gardens. They are weak fliers, and are often seen clambering about in vegetation or walking on the ground as they forage for insects, eggs and nestlings of other birds. They have a familiar deep resonant call which is associated with omens in many parts of its range.

The Andaman coucal or brown coucal is a species of non-parasitic cuckoo found in the Andamans, Coco and Table Islands. It is sometimes treated as a subspecies of the greater coucal. It is found mainly in forested habitats and thickly covered gardens.
