24-4-24 KANHA, INDIA - GREATER COUCAL (Centropus sinensis)

The Greater coucal (Centropus sinensis) is a large member of the cuckoo order of birds, the Cuculiformes. 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 head of the Greater coucal is black, upper mantle and underside are black glossed with purple. The back and wings are chestnut brown. There are no pale shaft streaks on the coverts. The eyes are ruby red. Juveniles are duller black with spots on the crown and there are whitish bars on the underside and tail. The males and the females are similar in plumage but females are slightly larger.

Greater coucals occur in the Indian Subcontinent and Southeast Asia. They don't migrate and can be found in mangroves, shrublands, grasslands near rivers, marshes, or creeks. They also frequently visit cultivated areas and rural gardens.

Greater coucals are most active in the warm hours of the morning and in the late afternoon. They sunbathe in the mornings singly or in pairs on the top of vegetation with their wings spread out. They communicate with each other using various calls. The common calls are a booming low 'coop-coop-coops' repeated and with variations and some duets between individuals. When duetting the female has a lower pitched call. Other calls include a rapid rattling 'lotok, lotok ...' and a harsh scolding 'skeeaaaw' and a hissing threat call.
