The Oriental stork (Ciconia boyciana) is a large, white bird with black wing feathers in the stork family Ciconiidae. It is closely related to and resembles the European white stork (Ciconia ciconia), of which it was formerly often treated as a subspecies. Unlike its more widespread cousin, the Oriental stork has red skin around its eye, with a whitish iris and black bill. The Oriental storks are found in Japan, Manchuria, Korea and Siberia.
