Coucou violet Chrysococcyx xanthorhynchus

Small, sluggish cuckoo, more often heard than seen; listen for the male’s explosive descending trills and a loud but unremarkable “chom-wit!”, often given in flight. Adult male glossy purple with white-barred belly. Female greenish-brown above with curvier, paler barring extending up to the face; juvenile similar but with stronger rufous tones to the wings and orangish crown. Female and juvenile similar to female Asian Emerald Cuckoo or Little Bronze Cuckoo; look for combination of orange bill and patchy iridescent green instead of the Emerald’s unbroken sheen or Little Bronze’s dark bill and duller sheen.
