Ecosystem and habitat

These green imperial-pigeon species have moderate forest dependence. They normally occur in altitudes from 0 to 1000 meters. The artificial ecosystems and habitats of these species include heavily degraded tropical and subtropical forests.

The natural ecosystems and habitats of these green imperial-pigeon species include tropical and subtropical mangrove forests, moist lowland forests, tropical and subtropical dry and moist shrublands.

Diet and feeding behavior

The diet of these green imperial-pigeon species consists mainly of fruits. Wild fruits, berries, figs, flowers, leaves and other plant matter are their primary food. They are arboreal and forage in the tree canopy.

Reproduction and breeding habits

The breeding season of these green imperial-pigeon species is from December to May in south India, Sri Lanka and Andaman and Nicobar Islands. The laying season is from March to June in northern India. They are monogamous and territorial.

These imperial-pigeon species nest on the fork of tree branches. The nest is a flimsy structure built with sticks and twigs. The clutch contains one or two white eggs. Both the parents share incubation and also care of nestlings.

The hatchlings are fed with nutritiously rich crop milk, which is a thick cheesy substance, produced in the crop of both males and females, by sloughing off squamous cells.

Migration and movement patterns

These green imperial-pigeon species are non-migratory resident birds.

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