Site description Fonualei IBA comprises the whole island of Fonualei which supports a recently established population of the Tongan megapode Megapodius pritchardii, and another globally threatened species, the friendly ground-dove Gallicolumba stairi. The island is an isolated active volcano, approximately 200 ha in area and the megapodes lay their eggs in soil heated by volcanic ducts. The sooty tern Sterna fusca nests in very large numbers on the island and two restricted range species, the wattled honeyeater Foulehaio carunculata and the Polynesian starling Aplonis tabuensis occur on the island.
