The Pitcairn Islands are a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The islands nearest to the Pitcairn Islands are Mangareva to the west and Easter Island to the east.
Between 1937 and 1951, Irving Johnson, skipper of the 29-metre brigantine Yankee Five, introduced five Galápagos giant tortoises to Pitcairn. Turpen, also known as Mr Turpen, or Mr. T, is the sole survivor. Turpen usually lives at Tedside by Western Harbour. A protection order makes it an offence should anyone kill, injure, capture, maim, or cause harm or distress to the tortoise.
The birds of Pitcairn fall into several groups. These include seabirds, wading birds and a small number of resident land-bird species. Of 20 breeding species, Henderson Island has 16, including the unique flightless Henderson crake; Oeno hosts 12; Ducie 13 and Pitcairn six species. Birds breeding on Pitcairn include the fairy tern, common noddy and red-tailed tropicbird. The Pitcairn reed warbler, known by Pitcairners as a 'sparrow', is endemic to Pitcairn Island; formerly common, it was added to the endangered species list in 2008.
A small population of humpback whales migrate to the islands annually, to over-winter and breed.
