Red-flanked Bluetail (Tarsiger cyanurus)
The red-flanked bluetail also known as the orange-flanked bush-robin is a migratory insectivorous species. breeding in mixed coniferous forest with undergrowth in northern Asia and northeastern Europe, from Finland east across Siberia to south to Japan. It winters mainly in southeastern Asia, in the Indian Subcontinent, the Himalayas, Taiwan, and northern Indochina. The breeding range is slowly expanding westwards through Finland (where up to 500 pairs now breed), and it is a rare but increasing vagrant to western Europe, mainly to Great Britain. It is similar in size and weight to the common redstart and slightly smaller (particularly with a slimmer build) than the European robin. Both sexes have a blue tail and rump, and orange-red flanks; they also have a white throat and greyish-white underparts, and a small, thin black bill and slender black legs.
