Black-faced Bunting

The black-faced bunting is a migratory bunting about 16 cm long that breeds in dense undergrowth along streams and rivers in the taiga zone of southern Siberia and across to Japan, and winters in north-east India, southern China and northern south-east Asia. (Wikipedia, general species account)

Its terrestrial feeding habits and general appearance give the impression of a dunnock with a bunting's bill. The breeding male has a dark grey head with a mix of yellow-green and black between the bill and eye and heavily streaked brown upperparts; females and young have a weaker head pattern with olive-grey cheeks. It eats seeds, and insects when feeding young, nests on the ground or in trees and lays four or five eggs. The call is a metallic tzii or tzee. (Wikipedia, general species account)
