Differs from Brush Cuckoo in smaller size and wing length and in having brighter yellow feet.


Endemic to Seram, Sula Islands, Bacan, Seram and Halmahera in the Moluccan Islands in Indonesia.
Population little known but certainly declining due to habitat loss.


Two subspecies recognized:

  • C. a. heinrichi on Halmahera and Bacan, Northern Moluccas (Indonesia)
  • C. a. aeruginosus on Buru, Ambon, Seram and Sula Islands, Southern Moluccas (Indonesia)

The subspecies aeruginosus was formerly included in Brush Cuckoo.


Moist lowland forests and moist montanes.
Occurs at 1000 - 1500m but reported much lower on Bacan.


No information. Feeds probably on insects.
