Eversmann's Redstart

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

The song is loud and lively, with a soft croaking call and a whistling call. The clutch is three to six pale green eggs with brownish-grey speckles (Wikipedia, general species account).
