Origin, geographical range and distributionThe snow pigeon species are distributed in Afghanistan, Pakistan, North India, Nepal, Bhutan, China, Myanmar, Kazakhstan, Tajikistan, Kyrgyzstan and Turkmenistan. The subspecies C. l. leuconota is distributed in Afghanistan, Pakistan, India, Nepal, Bhutan, Tajikistan, Kyrgyzstan and Turkmenistan. The pigeon subspecies C. l. gradaria is distributed in Bhutan, North Myanmar and China (Tibet, Qinghai and Yunnan provinces).
The Important Bird and Biodiversity Areas (IBA) of snow pigeon in Nepal are, Tamur valley and watershed, Shey-Phoksundo National Park, Sagarmatha National Park, Rara National Park, Makalu Barun National Park, Langtang National Park, Kanchenjungha Conservation Area, horpatan Hunting Reserve and Annapurna Conservation Area. The IBA of the pigeon in Tajikistan is Drumkul Lake. The IBA in Kyrgyzstan is Eastern Alai and in Afghanistan is Small Pamir.
Ecosystem and habitatThe snow pigeon species live in alpine zone (alpine tundra, rocky hill sides and sequestered valleys) in montane ecosystem dominated by grasses and low-growing shrubs. They are observed up to the snow line. They forage in the undulating plains and hill sides and roost in the cliffs and rocky ledges. They do not normally occur in forests.
Diet and feeding habitsThe diet of snow pigeon consists mainly of seeds, grains, grass, shoots, buds, flowers, berries and legumes.
Reproduction and breeding habitsThe breeding season of these pigeon species is from May to July in most of their range. They often breed in large colonies, nesting in crevices, cracks or caves in the face of cliffs or rock ledges. The nest is an untidy platform of sticks, grass and feathers. The clutch usually contains two eggs.
Migration and movement patternsThese pigeon species are altitudinal migrant birds. Post breeding dispersal of juveniles takes place. They may make local movements for feeding and breeding. These pigeon species have been found to descent to lower altitudes from the upland snow covered plains in winter.
Conservation status and concernsThe global population size of the snow pigeon (Columba leuconota) has not been quantified. The overall population size is considered to be stable. Their generation length is 5.6 years. These species have large range and population.
The snow pigeon does not approach the thresholds for being Vulnerable neither under the population trend criterion nor under the population size criterion. The IUCN (International Union for Conservation of Nature) has categorized and evaluated the snow pigeon (Columba leuconota) and has listed it as of "Least Concern".
