Cuco-brilhante Chalcites lucidus

A small glossy-greenish bird with a heavily barred throat, chest and tail. Parasitises gerygone species across its range. Distinguished from Horsfield’s Bronze-Cuckoo in Australia by lacking the dark stripe through the eye, and typically occurs in wetter and denser forest than Horsfield’s. Listen for territorial calls with a fast repeated rising “coo-ee” whistle (2 whistles per second), which can have phrases with a rougher and slower falling “tsee-ew” whistle (1 whistle per second) mixed in.
