Rufous-gorgeted Flycatcher

The rufous-gorgeted flycatcher is native to the Himalayas and Patkai ranges, central and southern China, northern Indochina and eastern Vietnam. Its natural habitat is subtropical or tropical moist montane forest, and the Himalayas are a major breeding range. It is known for its reddish-brown colour and a distinctly coloured patch on the throat (Wikipedia, general species account).

It performs altitudinal migrations and spends winters in places such as Thailand, north Laos and Vietnam. It is also common in temperate forest near boreal mountains in northern Kachin State, Myanmar. The source read does not name Bhutan, and gives no size, diet or breeding information, so none is stated.
