The Crab-plover is resident on the coasts and islands of the Indian Ocean, where it feeds on crabs and other small animals. They are gregarious and will feed in large groups, at night and during dawn and dusk as well as during the day; this crepuscular and nocturnal behaviour is more common during the breeding season. They breed around the Arabian Sea of Pakistan, Gulf of Oman and the Persian Gulf, Red Sea and Somalia in the months of April to July then disperse across the Indian Ocean in August as far as the Andaman Islands and Sri Lanka in the east and Tanzania and Madagascar
