About
The grey nightjar (Caprimulgus jotaka; also "gray" in some non-local literature) is a species of nightjar found in East Asia, breeding from southeastern Russia south through China, the Korean Peninsula and Japan to northern Indochina and westward along the Himalayas. It is largely migratory, wintering in Indochina south to Java in Indonesia, but is resident in warmer areas in the south of its breeding range. It is sometimes treated as a subspecies of the jungle nightjar (C. indicus), its South Asian relative.
