Red-flanked bluetail

The red-flanked bluetail, Tarsiger cyanurus, also called the orange-flanked bush-robin, is a small songbird of the Old World flycatcher family, 13 to 14 centimetres long and weighing 10 to 18 grams. Both sexes have a blue tail and rump and orange-red flanks, and the adult male also has dark blue upperparts while females and young males are plain brown above. It breeds in mixed coniferous forests with undergrowth from northern Sweden across Siberia to Kamchatka and Japan, and winters mainly in southeast Asia, the Indian subcontinent, the Himalayas, Taiwan and northern Indochina. It flicks its tail like a redstart and catches insects in the air or on the ground. The breeding range is slowly spreading west through Finland, and it is a rare but increasing visitor to Western Europe.
