White-backed thrush
Species of bird
From Wikipedia, the free encyclopedia
The white-backed thrush or Kessler's thrush (Turdus kessleri) is a species of bird in the family Turdidae. It is primarily resident or a short-distance altitudinal migrant, found in central China in Gansu, Qinghai, Sichuan, eastern Tibet, and northwestern Yunnan,[2][3] and also a scarce winter visitor in Bhutan, northeasternmost India (Arunachal Pradesh and Sikkim), and eastern Nepal.[2][4] It breeds in alpine scrub on rocky sites at altitudes of 3600–4500 metres, and descends down to 2100 metres, rarely to 1500 metres, in winter.[2][3]

It is a large thrush, 28 cm long (same size as a mistle thrush). The male has a black head, wings, and tail, and a pink body, dark pink below and pale pink to nearly white on the mantle (thus superficially resembling a rosy starling in plumage pattern, though larger and longer-tailed than that). The female is similar but drabber, with a dark brown head and the pink tinged greyer. Juveniles are similar to adult females, but with pale streaks on the head.[2] It is gregarious, forming flocks particularly in winter, but also on the breeding grounds, and often joins flocks of dusky thrush and red-throated thrush. It is omnivorous, feeding on insects, earthworms, and berries, with juniper cones ("berries") particularly important in winter.[2][3]
