Trochalopteron erythrocephalum
Range
Bhutan, China, India, Pakistan and Nepal
The chestnut-crowned laughingthrush is a member of the family Leiothrichidae found in Bhutan, China, India, Pakistan and Nepal. The silver-eared laughingthrush, formerly included as a subspecies, is now usually regarded as a separate species (Wikipedia, general species account).
That short account is the only source read for the Bhutan guide. It gives no plumage, size, habitat, diet or breeding information, so none is stated.
