The greater coucal species are distributed in Indian subcontinent, southeast Asia and China. In India, excluding the desert region, these species are distributed in all the states.The greater coucal nominate subspecies C. s. sinensis is distributed in Pakistan, northern India, Nepal, Bhutan, northern northeast India and south and southeast China. The subspecies C. s. parroti is distributed in southern India and Sri Lanka.
The greater coucal subspecies C. s. intermedius is distributed in Bangladesh, southern northeast India, Myanmar, south central China, Thailand, Cambodia, Laos, Vietnam and Peninsular Malaysia. The subspecies C. s. kangeangensis occurs in Kangean Islands (Indonesia).
The greater coucal subspecies C. s. anonymus is distributed in Basilan and Sulu Islands (Philippines). The subspecies C. s. bubutus is distributed in western Philippines, Borneo (Malaysia and Indonesia), Sumatra and Java.
Ecosystem and habitat
These greater coucal species have low forest dependence. They normally occur in altitudes from 0 to 1200 meters. The artificial ecosystems of these species include agricultural fields, rural gardens, palm oil plantations and orchards.The natural ecosystems and habitats of these greater coucal species include, tropical and subtropical mangrove forests, secondary forests, dry shrublands, bamboo thickets, moist shrublands, dry grasslands and wetlands, marshes and riverine habitats.
Diet and feeding behavior
The diet of these greater coucal consists mainly of insects. Caterpillars, insects, small mammals, lizards, snakes, frogs, bird eggs, nestlings, berries, wild fruits, orchard fruits are their primary food.Reproduction and breeding habits
The breeding season of the greater coucal species is during rains, from June to September in northern India. In southern India and Sri Lanka, the breeding season is throughout the year with a peak in March and April. These birds are monogamous.The nesting sites are located in dense vegetation, shrubs, bamboo thickets and trees with dense foliage. The nest may be located as high as six meters above the ground. As part of the courtship display the male coucal offers food to female.
The nest is built mostly by the male greater coucal. The nest is a deep cup-like structure built with sticks, twigs and other plant material. The typical clutch contains 3-5 chalky, yellowish white eggs. The chicks hatch out after 20 days and take further 20 days to fledge.
Migration and movement patterns
These greater coucal species are non-migratory birds. The birds in higher altitudes may move to lower levels during winter.Post breeding, the juvenile coucals may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
