It is one of the oldest islands in the group and has very few obviously volcanic features. The whole of its south coast is a low cliff which makes it an ideal nesting site for the endemic Waved Albatross. The updraft along the cliff, caused by the South-East Trade Winds, enables them to take off with relative ease. This the only location where you can see these birds that are so ungainly on land but so elegant once they take to the air. Boobies, tropic birds and Swallow-tailed Gulls also breed here.
