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.

This is a large species of cuckoo at 48 cm. The head 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. There are several geographic races and some of these populations are sometimes treated as full species. Earlier treatments included the brown coucal (C. (s.) andamanensis) under this name. Rasmussen & Anderton (2005) suggest that the race parroti may be a full species – the southern coucal which is found in peninsular India (northern boundary unclear). The race intermedius of the Assam and Bangladesh region is smaller than the nominate race found in the sub-Himalayan zone. Songs of the races are said to vary considerably. Race parroti of southern India has a black head and the underparts glossed blue and has the forehead, face and throat more brownish.{{cite book|author1=Rasmussen, P. C. |author2=J. C.

- Race parroti Stresemann, 1913 — found in Peninsular India (Maharashtra, Madhya Pradesh, Orissa and southwards). The upper back is black and the juvenile has unbarred wings.
- Race intermedius Hume, 1873 — smaller in size and found in Bangladesh, west Cachar and into Myanmar and the Chin Hills into China (Yunnan, Hainan), Thailand, Indochina and the northern part of the Malay Peninsula.
- Race bubutus Horsfield, 1821 — found in the southern part of the Malay Peninsula into the islands of Sumatra, Nias, Mentawai Islands, Java, Bali, Borneo, western Philippines (Balabac, Cagayan Sulu and Palawan). The wing is paler rufous in this race.
- Race anonymus Stresemann, 1913 — found in the southwestern Philippines (Basilan, Sulu Islands) and is shorter and darker winged than bubutus.
- Race kangeangensis Vorderman, 1893 — found in the Kangean Islands. This has pale and dark plumage phases.
The young when hatched have black skin and white hairy feathers (termed as trichoptiles) forming a fringe over the eye and beak.{{cite journal|author=Shelford, R.|title=On the pterylosis of the embryos and nestlings of Centropus sinensis|journal=Ibis| volume=42| issue=4| pages=654–667| year=1900|url=https://archive.org/stream/ibis67brit#page/653/mode/1up|doi=10.1111/j.1474-919X.1900.tb00763.x}}{{cite journal|doi=10.1071/MU942050c|author=Hindwood, KA|year= 1942|title=Nestling Coucal|volume= 42|issue=1|journal=The Emu|pages=52|url=http://www.publish.csiro.au/?act=view_file&file_id=MU942050.pdf}} The centre of the belly is pinkish and the upper mandible is black with a pink edge. The iris is brown, gape yellow and feet dark brown-gray.
The juvenile of race parroti is unmarked dull black on the underside (contra barred in the northern races) and much darker, dusky chestnut on the wings. Race bubutus found in Southeast Asia has a distinct call. Individuals from the Western Ghats are very similar in size to the lesser coucal Centropus bengalensis but the latter has a stubbier bill, shorter tail, wing tips extending beyond the tertials and a chestnut wing lining, dark eyes and a tail with green/bronze sheen. Females of the race parroti develop dusky or sooty wing coverts between November and January and the northern boundary of the race is along the Punjab plains where it forms intermediates with the northern forms.{{cite journal|last=Abdulali|first=Humayun|year=1956|title=Some notes on the plumages of Centropus sinensis (Stephens)|journal=J.

Behaviour and ecology
The greater coucal is a large bird which takes a wide range of insects, caterpillars, snails and small vertebrates such as the saw-scaled vipers.Venugopal, B (1981) Observations on the Southern Coucal Centropus sinensis feeding on the Saw-scaled Viper Echis carinatus. Newsletter for Birdwatchers . 21(12):19. They are also known to eat bird eggs, nestlings, fruits and seeds. In Tamil Nadu they were found to feed predominantly on snails Helix vittata. They are also known to feed on the toxic fruits of Cascabela thevetia (Yellow Oleander).{{cite journal| author=Natarajan, V|year=1993|title= Food and feeding habits of the Southern Crow-Pheasant Centropus sinensis parroti Stresemann (Aves : Cuculidae) at Pt.

They sunbathe in the mornings singly or in pairs on the top of vegetation with their wings spread out. The territory of a nesting pair has been found in southern India to be 0.9 to 7.2 ha (mean 3.8 ha).{{cite journal|author=Natarajan, V.|year=1997|title=Breeding biology of the Southern Crow-Pheasant Centropus sinensis parroti Stresemann (Aves: Cuculidae) at Point Calimere, Tamil Nadu.|journal=Journal of the Bombay Natural History Society|volume= 94|issue=1|pages=56–64}} They are most active in the warm hours of the morning and in the late afternoon.Natarajan, V (1993) Time budgeting by the Southern Crow-Pheasant Centropus sinensis parroti Stresemann (Aves : Cuculidae) at Pt. Calimere, Tamil Nadu. J. Bombay Nat. Hist. Soc. 90(1):92–95
The 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.
=Breeding=
The breeding season is after the monsoon in southern India but varies in other parts of its range but chiefly June to September.
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.{{cite journal|author1=Dhindsa, Manjit Singh |author2=Toor, HS |year=1981|title= Some observations on the nest of the Common Crow-Pheasant, Centropus sinensis (Stephens)|journal= J. Bombay Nat. Hist. Soc.|volume=78| issue=3| pages=600–602}} 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.{{cite book|author=Baker, ECS| year=1934| title= The nidification of birds of the Indian Empire. Volume 3| publisher= Taylor and Francis, London}} 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.{{cite journal|author=Peirce MA|title=Haematozoa of East African birds: II.

In culture
The bird is associated with many superstitions and beliefs.
