Güldenstädt's Redstart

Güldenstädt's or the white-winged redstart is one of the largest redstarts, 18 cm long and 21–29 g. It lives in the high mountains of the south-western and central Palearctic, including the Caucasus, Karakoram, Pamir, Himalaya, Tian Shan and Altai, in countries including China, India, Nepal, Bhutan, Mongolia and Central Asia.

It breeds at high altitude, 3,600–5,200 m, in alpine meadows and rock-fields, moving slightly lower in winter to subalpine Hippophae scrub. Some populations, notably the northernmost near Lake Baikal, migrate further. The adult male is black above except for a white crown, a white wing patch and an orange-red tail, with a black throat and upper breast and rich orange-red underparts. Females and immature males are brown above and orange-buff below with an orange-red tail. It feeds on fruit and a wide range of invertebrates. (Wikipedia, general species account)
