    Red List Rationale

    Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
