The Red-flanked Bluetail is a small songbird in the flycatcher family; it was formerly thought to belong in the same family as thrushes. These darlings are migratory, breeding in northern parts of Asia and Europe, and spending the winter in southern parts of Asia, including the Indian Subcontinent.
Males and female Red-flanked Bluetails both have blue tails and red-orange flanks, as the common name indicates. Males have dark blue upperparts, while females and juveniles have dull brown heads and backs.
The population trend for the Red-flanked Bluetail is stable and the conservation status is Least Concern as of November 2013.
