Black-backed Forktail

The black-backed forktail, occasionally called the black-throated forktail, is a forktail of the Old World flycatcher family. It has a broad white stripe across the forehead, a black crown, face and mantle, and white underparts sharply divided from the black above. The wings are largely black with a broad white stripe across the greater coverts (Wikipedia, general species account).

It is found in the Indian subcontinent and some adjoining regions of South-east Asia, ranging across Bangladesh, Bhutan, India, Myanmar, Nepal and Thailand. It is solitary but occasionally found in pairs or family groups. It breeds between March and June, both sexes building the nest and incubating the usually three pink, sparsely red-brown-specked eggs. The call is a short whistled 'tseep-dew'. The source does not mention China (Wikipedia, general species account).
