Gray Nightjar

Caprimulgus jotaka

The grey nightjar 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, its South Asian relative. The grey nightjar breeds and forages in early successional habitats surrounded by forests; its populations have declined since the 1970s in Japan. Like all nightjars, it is crepuscular to nocturnal, feeding on flying insects, including moths, beetles, flying ants, grasshoppers, and others. Source
