The chestnut thrush (Turdus rubrocanus) is a species of bird in the family Turdidae.
It breeds in the western Himalayas and central/southwestern China; it winters in Eastern Himalaya and northern Southeast Asia.
It is socially monogamous, but extra-pair partners are common.
[3] It exhibits sexual dichromatism, a form of sexual dimorphism in which males and females have different plumage colors.
However, this difference is typically not noticeable to human observers.
