The Himalayan Cuckoo (Cuculus saturatus) is a species of cuckoo in the genus Cuculus. It breeds from the Himalayas eastward to southern China and Taiwan. It migrates to southeast Asia and the Greater Sunda Islands for the winter.
It is a rare migrant to Singapore.
It favours wooded areas.
It has a typical morph and a hepatic morph. The typical morph has dark grey upperparts, a light grey head and breast, and barred underparts. The hepatic morph is brown above with brown-barred face and underparts.
The typical morph can be confused with the adult Indian Cuckoo, which is brownish instead of greyish.
