Rufous-tailed Rock-Thrush

The rufous-tailed rock-thrush, or common rock thrush, is a chat that breeds from southern Europe across Central Asia to northern China. It is strongly migratory, with all populations wintering in Africa south of the Sahara. It is a medium-sized but stocky thrush, 17 to 20 cm long. The summer male is unmistakable, with a blue-grey head, orange underparts and outer tail feathers, dark brown wings and a white back, while females and immatures have scaly brown plumage and reddish outer tail feathers (Wikipedia, general species account).

It is an uncommon visitor to northern Europe and has no subspecies.
