North Keeling

North Keeling is a small, uninhabited coral atoll, approximately 1.2 square kilometres (0.46 sq mi) in area, about 25 kilometres (16 mi) north of Horsburgh Island. It is the northernmost atoll and island of the Australian territory of the Cocos (Keeling) Islands. It consists of just one C-shaped island, a nearly closed atoll ring with a small opening into the lagoon, about 50 metres (160 ft) wide, on the east side. The lagoon is about 0.5 square kilometres (0.19 sq mi) in area. The island is home to the only surviving population of the endemic, and endangered, Cocos buff-banded rail, as well as large breeding colonies of seabirds. Since 1995, North Keeling Island and the surrounding sea to 1.5 kilometres (0.93 mi) from shore have been within the Pulu Keeling National Park.
