Ecosystem and habitat

These wedge-tailed green pigeon species have moderate forest dependence. They normally occur in altitudes from 1000 to 3000 meters.

The natural ecosystems and habitats of these species include tropical and subtropical dry forests, broad-leafed forests, tropical and subtropical moist lowland forests, second-growth forests, foothill forests and montane forests.

Diet and feeding behavior

The diet of these wedge-tailed green pigeon species consists mainly of fruits. Wild fruits, berries, figs and mulberries are their primary food. They normally forage in the understory and middle story of the forest.

Reproduction and breeding habits

The breeding season of these wedge-tailed green pigeon species is from April to August in India. Sometimes a second brood is raised. These species are monogamous and there is elaborate courtship.

The nesting sites are located on fork of tree branches. The nest is a flimsy platform of sticks, twigs and leaves. The clutch contains two white eggs. Both the parents incubate the eggs and take care of the young.

Migration and movement patterns

These wedge-tailed green pigeon species are non-migratory resident birds. They disperse locally after breeding. The populations in higher altitudes descend to the lower levels during winter.

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