Origin, geographical range and distribution

These banded bay cuckoo species are distributed in Indian subcontinent, China and Southeast Asian countries. The nominate subspecies C. s. sonneratii is distributed in India, Pakistan, Nepal, Bhutan, Bangladesh, Myanmar, China, Thailand, Laos, Cambodia, Vietnam, Malaysia and Singapore.

The banded bay cuckoo subspecies C. s. musicus is distributed in Indonesia (Java and Bali). The subspecies C. s. fasciolatus is distributed in Sumatra and Borneo of Indonesia and Palawan Island of Philippines. The subspecies C. s. waiti is distributed in Sri Lanka.

Ecosystem and habitat

These banded bay cuckoo species are moderately forest dependent. These species occur in altitudes from 0 to 900 meters. They inhabit both artificial and natural ecosystems. Their artificial terrestrial ecosystems includes agricultural lands, pasture lands and heavily degraded forests.

The natural ecosystem of these banded bay cuckoo species includes subtropical and tropical moist lowland forests, foothill forests, deciduous forests, subtropical and tropical dry shrublands, open woodlands, dense broadleaf forests, evergreen forests, fringe lands of forests and subtropical and tropical moist shrublands.

Diet and feeding behavior

The diet of these banded bay cuckoo species is mostly insects. Caterpillars, dragonflies, mantises, grasshoppers and beetles are their primary food. They glean the prey from foliage or the ground. They are also known to hawk the prey in the air.

Reproduction and breeding habits

These banded bay cuckoo species are brood-parasites, laying eggs in the nest of other birds and relying on the host to raise their young. The breeding season of these species coincides with the breeding season of the local host species.

The breeding season of these banded bay cuckoo species is from February to August in western India. The breeding season is from April to August in north-eastern India. In Sri Lanka, the breeding season is from June to October. The cuckoo chicks are known to evict the eggs or young of the host species.

Migration and movement patterns

The banded bay cuckoo is a partially migratory bird.

The populations in Southeast Asia are found to be resident. The populations in India are migratory, found mainly during the monsoons.

Post breeding, the juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.

Conservation and survival

The global population size of the banded bay cuckoo (Cacomantis sonneratii) has not been quantified. The overall population trend of these species is considered to be stable. Throughout its range it is reported to be common to fairly common. The generation length is 4.2 years. Their distribution size is about 14,800,000 sq.km.

The banded bay cuckoo (Cacomantis sonneratii) does not approach the thresholds for being Vulnerable, either under the range size criterion, or under the population trend criterion, or under the population size criterion. Loss of habitat is the main threat that may endanger the survival of these species.

IUCN and CITES status

The IUCN (International Union for Conservation of Nature) has categorized and evaluated the cuckoo species and has listed it as of "Least Concern". CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for the banded bay cuckoo (Cacomantis sonneratii).
