Eagle Islands is a group of two islands in the Chagos Archipelago. They are located on the central-western rim of the Great Chagos Bank, which is the world's largest coral atoll structure. There was once a coconut plantation in the islands as well as a small settlement of plantation workers. But at the time of Commander Robert Moresby's survey of the Chagos, in 1838, this island was populated only occasionally. In 1975 the Joint Services Expedition to Danger Island (JSDI), made a topographical survey of the coral reefs, an ecological survey of the corals on it and a study on the metabolism of the reef. Since 1998 the islands are part of the Chagos Archipelago Strict Nature Reserve and it is forbidden to land on the islands or anchor a boat nearby. The islands have large populations of nesting seabirds.
