Ducie Island is an uninhabited atoll in the Pitcairn Islands. It lies east of Pitcairn Island, and east of Henderson Island, and has a total area of , which includes the lagoon. It is long, measured northeast to southwest, and about wide. The island is composed of four islets: Acadia, Pandora, Westward and Edwards. Despite its sparse vegetation, the atoll is known as the breeding ground of a number of bird species. More than 90% of the world population of Murphy's petrel nests on Ducie, while pairs of red-tailed tropicbirds and fairy terns make around 1% of the world population for each species. Ducie was first discovered in 1606 by Pedro Fernandes de Queiros, who named it Luna Puesta, and rediscovered by Edward Edwards, captain of , who was sent in 1790 to capture the mutineers of . He named the island Ducie in honour of Francis Reynolds-Moreton, 3rd Baron Ducie. In 1867, it was claimed by the United States under the Guano Islands Act, but the United Kingdom annexed it on 19 December 1902 as part of the Pitcairn Islands. Due to its inaccessibility and the distance from Pitcairn Island, Ducie is rarely visited, receiving one to two visits a year from cruise ships. History The island was discovered by a Spanish expedition led by Portuguese sailor Pedro Fernandes de Queirós on 26 January 1606, during an expedition that began in Callao, Peru. Supported by Pope Clement VIII and Philip III of Spain, Queirós was given the command of the San Pedro, San Pablo and Zabra. The fleet was nicknamed Los Tres Reyes Magos ("The Three Wise Men"). The objective of the expedition was to take soldiers, friars and provisions to establish a colony in the Santa Cruz Islands. Ducie Island was the first of eighteen discoveries on the trip. Queirós named the island Luna Puesta (roughly, "moon that has set"). On the same day, he also sighted two more islands, one that he named San Juan Bautista ("St John the Baptist"), and the other La Encarnación ("the Incarnation"). It is unclear which one was Henderson island and which one was Pitcairn. The confusion was later compounded when a chart produced by Admiral José de Espinosa marked Ducie as La Encarnación, rather than as Luna Puesta. The island was rediscovered and named Ducie Island on 16 March 1791 by Captain Edward Edwards, of , who had been despatched from
