Justification of Red List category
Conservation action has helped this species recover from an all-time population low in 1980. It still qualifies as Vulnerable because numbers remain very small and its range is small and restricted to a single island. However, if there are any future declines in available habitat, it may qualify for uplisting to Endangered.
850-1000 mature individuals
