Chestnut thrush

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.
