This individual is an immature, and may easily be confused with the hepatic female of the larger Oriental Cuckoo. I saw it for three straight days along the banks of Bued River, after which it was gone. Solitary and secretive, it has a total length of 9 inches. This was the first time I got some video footage of this species.
Many thanks to Rob Hutchinson (www.birdtourasia.com) for confirmation of the bird ID.
