The Banc d'Arguin National Park of Bay of Arguin lies in Western Africa on the west coast of Mauritania between Nouakchott and Nouadhibou. The World Heritage Site is a major breeding site for migratory birds, including flamingos, broad-billed sandpipers, pelicans and terns. Much of the breeding is on sand banks including the islands of Tidra, Niroumi, Nair, Kijji and Arguim. The surrounding waters are some of the richest fishing waters in western Africa and serve as nesting grounds for the entire western region.
