Tarsiger cyanurus (Pallas, 1773)
Family: Passeriformes > Muscicapidae
Once regarded as an extreme vagrant, records of this relative of the Robin have increased dramatically, likely following a marked population increase in the forests of eastern Finland, where it was first recorded breeding in the 1940s.
This migratory species breeds from Finland east to Kamchatka and winters across parts of China.
