The Nightingale Islands are a group of three islands in the South Atlantic Ocean, part of the Tristan da Cunha territory. They consist of Nightingale Island, Middle Island and Stoltenhoff Island. The islands are administered by the United Kingdom as part of the overseas territory of Saint Helena, Ascension and Tristan da Cunha. The Nightingale Islands are uninhabited.
Nightingale Island is the smallest of the four main islands of the Tristan da Cunha Group, measuring only 4 square kilometres (1.5 sq mi), and lies 30 kilometres (18.6 mi) away from Tristan and 22 kilometres (13.7 mi) from Inaccessible. Stoltenhoff and Alex (also known as Middle Island), are really two large islets rather than conventional islands.
Nightingale, a tiny island, is home to more than 3 million pairs of seabirds and at a density of around 1.3 pairs per square meter, almost the entire vegetated island is occupied. Both the Nightingale and Wilkins' Bunting are found nowhere else in the World.
