Range

Habitat
They visit rocky hill sides and sequestered valleys, seen up to the snow line. They frequently feed in the fields during the day, but roost in the cliffs.
Reproduction
They breed in colonies. The nests are placed in crevices or caves in the face of cliffs or ledges of rock. Nest is an untidy interlaced structure made of sticks, grass, straw, feathers etc. The nests are generally reused every year with minor repairing. Generally two eggs are laid which are incubate for about 24-26 days. The young fledge after another 40-45 days,
Feeding habits
They feed on berries, grain, buds and shoots.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
In winter both races move to the warmer climes of lower altitudes, occurring down to 1500 m, occasionally to as low as 750 m. Makes movements twice daily between roosts in mountains and arable fields and inhabited valley below.
