Habitat

These cuckoo species inhabit dry, deciduous forests, thorny, dry scrub jungle, open woodland, thorny jungle, plains and dry lowlands. They avoid dense forests and extremely dry ecosystems.

Diet and feeding habits

The diet primarily consists of insects, grasshoppers, hairy caterpillars, termites, land snails, fruits and berries.

Breeding

The Jacobin cuckoo species usually breed during June to August in north India. The south Indian subspecies breed during January to March. They do not build nest and lay their eggs in the nest of host birds like babblers. The hatchlings are raised by the host birds.

Distribution

The subspecies C. j. pica is distributed in sub-Saharan Africa, India, Nepal, Tibet and Myanmar. The subspecies C. j. jacobinus is distributed in South India and Sri Lanka. The subspecies C. j. serratus occurs in South Africa.

Movement and migration patterns

The South Indian cuckoo subspecies make local migrations. The South African subspecies is believed to make breeding migration to north India. Some ornithologists are of the view that only C. J. pica migrates between India and Africa.

Conservation status and concerns

The global population of these species has not been quantified. The overall population trend is stable. These species have extremely large range and hence considered not "Vulnerable".

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these Jacobin cuckoo species and has listed them as of "Least Concern".
