Horsfield Zümrüt Guguğu Chrysococcyx basalis

A small greenish bird with a barred chest and tail, and a dark stripe through the eye that droops down across the cheek. Young birds can be almost unbarred and may appear similar to the grayer Black-eared Cuckoo. Often perches prominently on top of a shrub or tree, and calls repeatedly with a loud piercing descending whistle. Occurs in Indonesia and across much of Australia (including arid inland areas).
