Grey-backed Thrush

The grey-backed thrush breeds in north-eastern China and the Russian Far East and winters in southern China and northern Vietnam. It is a medium-sized thrush, 20–23 cm long with a mean weight of 66.7 g. It nests and forages mainly in deciduous or evergreen forest with rolling terrain, rarely above 1,100 m, and eats both fruit and insects. (Wikipedia, general species account)

Males have a slate-grey back and chest, a white chin and belly and rufous flanks, while females have grey or brown backs with dark spots on the chest. A captive pair laid five eggs that hatched 14 days after the first was laid, and the young left the nest 12 days later. (Wikipedia, general species account)
