The northern hawk-cuckoo,rufous hawk-cuckoo, or Horsfield's hawk-cuckoo (Hierococcyx hyperythrus) is a bird in the family Cuculidae formerly thought to be conspecific with Hodgson's hawk-cuckoo (Hierococcyx fugax) and placed in the genus Cuculus .
It is found in eastern China, North and South Korea, far eastern Russia, [2] and Japan. Northern populations winter in Borneo.
Juvenile northern hawk-cuckoos have a yellow skin patch on the underside of each wing, which parents use to detect whether offspring are begging for food. [3]
