Hierococcyx fugax is found in far southern Burma, southern Thailand, Malaya, Singapore, Borneo, Sumatra and western Java.
The Malaysian hawk-cuckoo occurs in a variety of forest types from plains level up to 1700 metres on Sumatra. It can also be found in cocoa and rubber plantations.
Insects, mainly caterpillars, but also cicadas, beetles, small butterflies and locusts, in addition fruits and berries. Active in bushes and understorey, gleaning prey from foliage.
