The camouflaged grey nightjar (Caprimulgus jotaka) is very dark, and coarsely marked in silvery grey and brown which helps it blend seamlessly into its surroundings. It breeds in open areas within dense forests, as well as mountain ridges. Found in East Asia, breeding from south-eastern 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.
