Hill Pigeon

The hill pigeon, also called the eastern rock dove, is a stout pigeon similar in size and general appearance to the rock dove but told by a broad white band across the black tail. It also has a paler mantle and upper wings and a white patch on the back. In flight its tail pattern resembles that of the snow pigeon but lacks that species' contrast between head and neck (Wikipedia, general species account).

It frequents open, rugged country from 1,500 to 6,100m. It is gregarious all year, feeding in flocks in terraced, cultivated fields, and nests in dense colonies on cliffs, gorges and rocky outcrops. In Tibet nests are often placed in houses, inhabited or empty, or in holes in walls. The nest is a platform of twigs or plant stems in which generally two eggs are laid.
