Range extends from southern China through Laos, Thailand, peninsular Malaysia, Borneo, Sumatra, Java, and Nias, with varying elevations depending on the location.
Diet
This insectivorous species uses the 'sally-stall' technique, pursuing prey from a perch and stalling before seizing it. Foraging occurs most commonly at a height of about 9.5 m, with a range of 4.3–13.7 m. Diet comprises various arthropods, including Phasmatodea, Orthoptera, and Lepidoptera larvae.
