The black-faced warbler is a bush warbler found in Bhutan, China, India, Myanmar, Nepal and Vietnam. Its natural habitats are subtropical or tropical moist lowland forest and moist montane forest and scrub, occurring at altitudes of 1,500 to 2,700m and occasionally down to 600m (Wikipedia, general species account).
It is non-migratory. That short account is the only source read for the Bhutan guide, and it gives no plumage, size, diet or breeding information, so none is stated.
