The common rock thrush (Monticola saxatilis), formerly rufous-tailed rock thrush or rock thrush, is a chat belonging to the family Muscicapidae. It was formerly placed in the family Turdidae.It breeds in southern Europe across Central Asia to northern China. This species is strongly migratory, all populations wintering in Africa south of the Sahara. It is an uncommon visitor to northern Europe. Its range has contracted somewhat at the periphery in recent decades due to habitat destruction but it is not considered globally endangered. This species breeds in open dry hilly areas, usually above 1500 m. It nests in rock cavities, laying 4–5 eggs. It is omnivorous, eating a wide range of insects, berries and small reptiles. The male common rock thrush has a clear and tuneful song.
