Siberian Blue Robin

The Siberian blue robin, like similar small European species, is often called a chat. It is a migratory insectivorous species breeding in the eastern Palearctic from Siberia and northern Mongolia through north-eastern China and Korea to Japan, and winters in southern and south-eastern Asia and Indonesia. It feeds on the ground but is very skulking. The genus name Larvivora comes from the Neo-Latin for caterpillar-eating, and cyane is Latin for dark blue (Wikipedia, general species account).
