Origin, geographical range and distribution

These Nilgiri imperial-pigeon species are endemic to India. They are distributed in the Western Ghats of south west India. They occur in the states of Tamil Nadu, Kerala, Karnataka, Goa and southern most Maharashtra.

Ecosystem and habitat

These Nilgiri imperial-pigeon species have high forest dependence. They normally occur in altitudes from 0 to 2000 meters.

The natural ecosystems and habitats of these species include tropical and subtropical moist lowland forests, evergreen forests, tropical and subtropical moist montane forests and dense deciduous forests.

Diet and feeding behavior

The diet of these Nilgiri imperial-pigeon species consists mainly of fruits. Wild fruits, berries, figs and wild nutmegs are their primary food.

These imperial-pigeons are highly arboreal. The fruits are plucked and swallowed whole. Occasionally they go to the ground to drink. They are known to visit salt-licks.

Reproduction and breeding habits

The breeding season of these Nilgiri imperial-pigeon species is from January to May (Rasmussen and Anderton 2005).

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 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.
