Red-flanked Bluetail

The red-flanked bluetail, also called the orange-flanked bush-robin, is a small flycatcher, 13 to 14cm long and 10 to 18g. Both sexes have a blue tail and rump, orange-red flanks, a white throat and greyish-white underparts; the adult male additionally has dark blue upperparts, while females and immature males are plain brown above apart from the blue rump and tail (Wikipedia, general species account).

It breeds in mixed coniferous forests with undergrowth in northern Asia, parts of central Asia and north-eastern Europe, and is migratory, wintering mainly in south-east Asia, the Indian subcontinent, the Himalayas, Taiwan and northern Indochina. The nest is built on or near the ground, with three to five eggs incubated by the female. Its call is a typical chat 'tacc'.
