Thousands of red tailed tropicbirds and red footed boobies (below left and right) nest on the island, which is one of the most important sea bird breeding grounds in the Pacific region. Feathers from the tropicbird are gathered for traditional costumes. Terns, noddies and frigatebirds are also found in large numbers. The kota or great frigatebird (centre) that nests there has become an unofficial emblem for the Cook Islands.
