Behaviour and ecology

They frequent 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. They are generally shy and wary. Gatherings of 150 or more occur in winter, often in company of Hill Pigeon and in some areas with Rock Pigeon too.

In the summer, they descent to lower heights and are found in pairs or small flocks. 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.

They feed on berries, grain, buds and shoots.
