A slim and beautiful roller with very long outer tail feathers. In flight, the spectacular wings are half pale blue and half dark blue. Found in dry savanna and other open country. Usually seen singly or in pairs. Easily separated from Lilac-breasted Roller by the blue throat. Occasionally lacks elongated outer tail feathers, and then very similar to European Roller, but separated by the dark blue rather than black outer wing. The calls are rough rasps.
