Normal flight is leisurely, but impressive bursts of speed are used when hunting. Found in thick savanna, woodland, plantations, forest, and along cliffs and forest edge. Mainly eats bats, which are hunted at dawn and dusk. Sometimes seen in flight during the day. Call is a series of high-pitched mournful whistles.
