Taiga flycatcher 
or red-throated flycatcher (Ficedula albicilla, Đớp ruồi Taiga)

The taiga flycatcher or red-throated flycatcher (Ficedula albicilla) is a migratory bird in the family Muscicapidae.
The bird breeds in northern Eurasia from eastern Russia to Siberia and Mongolia. It is a winter visitor to South and South-east Asia in Bangladesh, Bhutan, India, Cambodia, Laos, Myanmar, Nepal, Malaysia, Thailand, China, Vietnam, and Japan.

The genus name Picedula is from Latin and refers to a small fig-eating bird (ficus, "fig") supposed to change into the blackcap in winter.
The specific name albicilla is from Latin albus, white, and Neo-Latin cilla tail; this meaning of cilla arose from a misunderstanding of motacilla, the name for the wagtail.
