Sturnia sinensis
Range
Breeds in southern China and northern Vietnam; winters in South-east Asia; also listed in India, Japan, South Korea and Taiwan
The white-shouldered starling, Sturnia sinensis, has blue eyes, a grey bill and a white shoulder patch. Males have a light brown head and breast with a white belly, and females are darker brown on the back and belly. It is usually found in large flocks. Gmelin described it in 1788 as Oriolus sinensis and no subspecies are recognised (Wikipedia, general species account).
It breeds in southern China and northern Vietnam and winters in South-east Asia, and is also listed in India, Japan, South Korea and Taiwan. The source does not name Nepal and gives no size, habitat, diet or breeding detail, so its Nepal status should be checked (Wikipedia, general species account).
