Justification of Red List category
This species occupies an extremely small breeding range restricted to only a few islands. The population has undergone a population increase due to previous conservation efforts. Albeit, based on threats such as invasive species, fisheries and climatic events, habitat quality is thought to be undergoing a continued decline. It consequently qualifies as Near Threatened. If ongoing and potential threats continue to degrade the species's habitat however, it may warrant uplisting in the future.
