The Siberian stonechat or Asian stonechat (Saxicola maurus) is a recently validated species of the Old World flycatcher family (Muscicapidae). Like the other thrush-like flycatchers, it was often placed in the Turdidae in the past. It breeds in the East Palearctic including in easternmost Europe and winters in the Old World tropics.
It resembles its closest living relative the European stonechat (S. rubicola), but is typically darker above and paler below, with a white rump and whiter underparts with less orange on the breast. The male in breeding plumage has black upperparts and head (lacking the brownish tones of the European stonechat), a conspicuous white collar, scapular patch and rump, and a restricted area of orange on the throat.
The female has pale brown upperparts and head, white neck patches (not a full collar), and a pale, unstreaked pinkish-yellow rump. Males in winter plumage are intermediate between summer males and females, with a supercilium resembling the whinchat (S. rubetra); from this species and the female it can be distinguished by the full white collar.
