Eversmann's Redstart

Eversmann's redstart, also called the rufous-backed redstart, is one of the larger redstarts, 15–16 centimetres long with a wingspan of 25.5–27 centimetres and a weight of 15–22 grams. The bill and legs are black. The breeding male has a black mask and grey crown and nape; the back and rump are rufous, as is the tail apart from the darker central feathers. The wings are dark with white patches, and the underparts mainly rufous with white on the belly and undertail-coverts. Non-breeding and first-winter males are much duller and browner; females are mostly grey-brown. (Wikipedia, general species account)

It breeds in the mountains of Central Asia and southern Siberia, from the Tien Shan range to the Tarbagatay and Altay Mountains and near Lake Baikal. Some birds move downhill for the winter while others, especially in the northeast of the range, migrate longer distances. The wintering range extends from southern Iraq through Iran and Pakistan to the western Himalayas of Kashmir, and a few birds reach eastern Arabia. It has occurred as a vagrant in Israel and Turkey.
