Amur Stonechat

The Amur stonechat or Stejneger's stonechat (Saxicola stejnegeri) is a species of stonechat native to eastern Asia. It breeds in central and eastern Siberia, Japan, Korea, northeastern China, and eastern Mongolia, and migrates south to southern China and Indochina in winter. It is a small bird 11.5–13 cm long, very closely similar to the Siberian stonechat in both plumage and behaviour, differing in only small details, notably having a slightly broader-based bill 4.7–5.7 mm wide (4.0–4.9 mm wide in Siberian stonechat) and slightly less white on the rump.
