[edit] Identification

25cm.

  • Slate-grey upperparts
  • Contrastingly blackish tail and uppertail-coverts, tail with white tip and whtie spots at sides
  • Unbarred white bend of wing below
  • Light grey throat and breast
  • White belly with black bars
  • Undertail-coverts often barred black
  • Yellow eye-ring

[edit] Similar Species

Oriental Cuckoo and Himalayan Cuckoo are larger and have different calls.
Very similar to the Madagascar Cuckoo; probably not always safely distinguished in the field. Thin bars, weakly marked undertails and a pale head are good features for Madagascar Cuckoo.

Breeds from northern Afghanistan and northern Pakistan east trough the Himalayan foothills of India and Nepal to Bangladesh to northern Burma. Also across China to Ussuriland (Russia), Korea and Japan.
Winters in peninsular India, Sri Lanka and eastern Africa.
Common to fairly common in its range.
