The island is a focal point for seabirds of various species. Eight species or subspecies of seabirds nest on it. The most numerous is the red-footed booby, which nests in colonies, using trees on many parts of the shore terrace. The widespread brown booby nests on the ground near the edge of the seacliff and inland cliffs. Abbott's booby (listed as endangered) nests on tall emergent trees of the western, northern and southern plateau rainforest, the only remaining nesting habitat for this bird in the world.
