There are quite a lot of these redstarts around at the moment - they are small and quite tame, and recognised by their quivering red tails. The female is less colourful. Apart from the rufous red tail, the rest of the body is quite drab, but there is also a characteristic white mark on the wing.

The male is more colourful but not so common - it has a bright combination of black head, white hind neck and reddish tail and underparts:

The Daurian redstarts come here from the north in winter, arriving around December and disappearing again in the spring.
