Takutea

Takutea, in the Cook Islands, is a small uninhabited island 21 kilometres (13 miles) northwest of Atiu in the southern Cook Islands. Because it is only 1.22 km (0.47 sq mi) in size and has a very dangerous landing at the northwest corner of the reef, it has been designated a wildlife sanctuary, mainly for the red-tailed tropicbirds and red-footed boobies.
