Caprimulgus jotaka



From southeast Siberia, Korea, Japan, east and south China to Burma, Bangladesh, Nepal to Pakistan.
Northeastern birds winter in Indochina, the Philippines, Malaysia, Singapore and Indonesia. Fairly common in most of its range but scarce in Singapore. Accidental vagrant to Aleutian Islands, Alaska.


Formerly considered conspecific with Jungle Nightjar and Palau Nightjar.


Two subspecies recognized:


Forests (different types), open woodland, scrubland, farmland, plantations. In the Himalayas in sparsely vegetated ravines. In winter also recorded in big cities.


Nocturnal. Roosts in trees (quite high) and on boulders. Sings from perch or ground.


Breeding time different throughout range. May to August in Japan. Lays 1 - 2 eggs on bare ground, usually rocks, covered by vegetation. No nest.


Movements of this species are poorly understood. The northern jokata is highly migratory. Southern races maybe sedentary with some altitudinal movements.
