Diederik Cuckoo

The Diederik Cuckoo is a smallish cuckoo at 18 to 20 cm. Adult males are green above with copper-sheened areas on the back and whitish underparts. They have a broken white eyestripe, a green moustauchial stripe, and green outer tail feathers with small white spots.
Females show more copper above, and have coppery barring on the flanks. The underparts are often washed brownish. Juveniles are more copper-coloured above and browner below than the females, and the flank markings are brown blotches. (wikipedia)
