On Tetiaroa, 15 bird species have been identified, including 11 breeding seabirds, 4 migratory terrestrial birds and 1 native breeding terrestrial bird. The particularity of atolls, compared to high islands, is the presence of more breeding seabirds that have direct access to food. Despite the small number of species, the bird colonies are very important in Tetiaroa. This atoll represents a real sanctuary for these animals.
