About the Sunda Cuckoo
The Sunda cuckoo or Sunda lesser cuckoo is a South-east Asian bird belonging to the genus Cuculus in the cuckoo family, Cuculidae. It was formerly classified with the Himalayan cuckoo and Oriental cuckoo in a single species, C. saturatus, but is now often regarded as a separate species based on differences in voice, size and plumage.

ID tip
It is 29–30 cm long. The upperparts, throat and upper breast are dark grey. The rest of the underparts are buff with black bars. The tail is blackish with white spots. The female also occurs in a rufous form which has reddish-brown upperparts, paler underparts and black barring both above and below. The Himalayan cuckoo and Oriental cuckoo are similar to the Sunda cuckoo but paler with less buff-coloured underparts and narrower black bars. The song of the Sunda cuckoo usually consists of a short first note followed by two or three longer and lower "hoop" notes.
