In India, these pigeons are distributed in the states of Uttarakhand, Sikkim, northern West Bengal, Arunachal Pradesh, Nagaland, Manipur and Mizoram.
Ecosystem and habitatThese ashy wood pigeon species are moderately forest dependent. They inhabit various forest and shrubland ecosystems.
These pigeon species inhabit tropical and subtropical forests, tropical and subtropical moist lowlands, temperate forests, temperate shrublands and tropical and subtropical high altitude shrublands. These species occur in altitudes from 1200 to 3200 meters.
Diet and feeding behaviorThe diet of these ashy wood pigeon species is mostly fruits, berries, seeds and plant material. These birds are mostly frugivorous and their primary food is wild fruits and berries. They have been observed to feed on other plant material and small snails.
Reproduction and breeding habitsThe breeding season of these ashy wood pigeon species is from May to August. Their tree-nest is made of twigs and sticks. One or two white eggs are laid in the feather lined nest. The egg is incubated for about 22 days. The hatchlings fledge in about 28 days.

The overall population size of these ashy pigeon species is considered to be decreasing. Throughout its range it is reported to be rare and secretive. The generation length is 5.6 years. Their distribution size is about 2,990,000 sq.km.
The ashy wood pigeon (Columba pulchricollis) does not approach the thresholds for being Vulnerable either under the range size criterion or under the population trend criterion or under the population size criterion. The ongoing destruction of their habitat is the main threat that may endanger the survival of these species.
