Origin, geographical range and distribution

These mountain imperial-pigeon species are distributed in India, Nepal, Bhutan, Myanmar, Thailand, Cambodia, Laos, Vietnam, Malaysia, Brunei, Indonesia and China.

In India, these imperial-pigeon species are distributed in the states of Sikkim, northern West Bengal, Assam, Meghalaya, Arunachal Pradesh, Nagaland, Tripura, Manipur and Mizoram.

The nominate mountain imperial-pigeon subspecies D. b. badia is distributed in Malay Peninsula, Sumatra (Indonesia), Borneo (Indonesia and Malaysia) and west Java (Indonesia).

The imperial-pigeon subspecies D. b. griseicapilla is distributed in northeast India (Nagaland, Manipur, Arunachal Pradesh, Tripura, Mizoram), Myanmar, Thailand, Cambodia, Laos, Vietnam and south central China.

The imperial-pigeon subspecies D. b. insignis is distributed in central Nepal, Bhutan and India (Sikkim, northern West Bengal, Assam, Meghalaya).

Ecosystem and habitat

These mountain imperial-pigeon species have high forest dependence. They normally occur in altitudes from 0 to 2300 meters.

The natural ecosystems and habitats of these imperial-pigeon species include tropical and subtropical moist montane forests, evergreen and deciduous forests, tropical and subtropical moist lowland forests, old-growth forests and mangrove forests.

Diet and feeding behavior

The diet of these mountain imperial-pigeon species consists mainly of fruits. Wild fruits, berries, figs and nutmeg are their primary food. The fruits are plucked and swallowed whole. Occasionally they go to the ground to drink.

Reproduction and breeding habits

The breeding season of these mountain imperial-pigeon species is extended depending upon food availability and weather. The subspecies D. b. insignis (Nepal, Bhutan and India) breeds from March to August.

These imperial-pigeon species are monogamous. The nesting sites include fork and branches of trees. The nest is a flimsy platform built with sticks and twigs.

The clutch contains one or two eggs. Both the parents incubate the eggs. The nestlings are fed with crop milk, a thick cheesy substance, derived from sloughed off squamous cells from the crop of both male and female birds.

Migration and movement patterns

These mountain imperial-pigeon species are non-migratory resident birds. The populations in higher altitudes descent to lower levels in winter.

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