breeds very locally around the Mediterranean and the north of the western Indian Ocean on islands and coastal lagoons. Most of the population is somewhat migratory, wintering further south to north Africa and India, and a few birds have wandered to western Europe. A vagrant individual was reportedly seen on Antigua, April 24, 1976.
