The two inner front toes are connected, but not the outer one. The weakness of the feet and legs is reflected in their behaviour, rollers do not hop or move along perches and seldom use their feet other than for occasional lurching leaps along the ground pursuing escaping prey.Rollers get their name from their impressive courtship flight, a fast, shallow dive from considerable elevation with a rolling or fast rocking motion, accompanied by loud raucous calls. All rollers appear to be monogamous and highly territorial. They make unlined nests in natural tree holes or in termite hills. Sometimes they take over woodpecker's or kingfisher's nest holes.
