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 Himalaya.[2] 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.[2] It is sometimes treated as a subspecies of the jungle nightjar (C. indicus), its South Asian relative.[3][4] The grey nightjar breeds and forages in early successional habitats surrounded by forests; its populations have declined since the 1970s in Japan.[5] Like all nightjars, it is crepuscular to nocturnal, feeding on flying insects, including moths, beetles, flying ants, grasshoppers, and others.[3]
