The Fan-tailed Cuckoo primarily feeds on insects, especially grasshoppers and beetles. It is found across a wide range from southern Asia to northern Australia. citation The Fan-tailed Cuckoo is a medium-sized cuckoo with slate‑grey upperparts, rufous underparts and a boldly barred tail that occurs across much of Australasia, breeding in eastern, southern and south‑western Australia (including Tasmania) and also found in New Guinea, New Caledonia, the Solomon Islands, Fiji and Vanuatu. It feeds mainly on hairy caterpillars and a wide variety of insects and their larvae, locating prey from exposed perches and sometimes catching it in flight, and will also take some fruits and small vertebrates on occasion.
