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.

24-5-2023 SUKAU RIVER LODGE, BORNEO - GREATER COUCAL (Centropus sinensis)

The greater coucal or crow pheasant (Centropus sinensis), 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.

Greater coucals are monogamous, and the courtship display involves chases on the ground and the male brings food gifts for the female. The female lowers her tail and droops her wings to signal acceptance. The nest is built mostly by the male over about three to eight days. The nest is a deep cup with a dome in dense vegetation inside tangles of creepers, bamboo clump or Pandanus crowns. They can be built as high as 6m above the ground and the typical clutch is 3–5 eggs. The eggs (of size 36–28 mm weighing 14.8 g ) are chalky white with a yellow glaze when laid that wears off. Both the male and the female take part in nest building. They lay 2 to 4 eggs that hatch after 15–16 days of incubation. The chicks take 18–22 days to fledge. A study in southern India found that 77% of the eggs hatched and 67% fledged. Nests with eggs were sometimes abandoned or marauded by the Indian jungle crow Corvus macrorhynchos culminatus.

Haemosporidia closely related to those that cause malaria have been found in their red blood cells. One species, Haemoproteus centropi, is described from cuckoos such as Clamator jacobinus and Centropus sinensis and is spread by mosquitoes. Immature Haemaphysalis ticks have been found feeding on greater coucals.
