Lilac-breasted Roller (Coracias caudata) in Kruger National Park. These are found throughout eastern and southern Africa. Rollers get their name from their impressive courtship flights, fast, shallow dives from considerable elevation with a rolling or fast rocking motion, accompanied by loud raucous calls. The Lilac-breasted Roller feeds on grasshoppers, beetles, lizards, crabs, and small amphibians.
