Introduction: Intentional Species Notes for this Location:
A recent study has highlighted the pervasiveness of these mammals on the island of Juan de Nova and the strong impact they have on populations of seabirds including terns (Faulquier, 2005). For example, dozens of fresh corpses of adults were found over an area of less than one hectare in one afternoon. Amongst the tern species, the swift tern (Sterna bergii), whose population is estimated at 250 pairs on the island of Juan de Nova, is perhaps the most vulnerable. Even minimal predation by cats could lead to their rapid decline and even extinction. Management Notes for this Location:
