Justification:
Listed as Least Concern since, although its currently known Extent of Occurrence is not much greater than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under very serious 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.

History:

2006	–	Least Concern (IUCN 2006)
2006	–	Least Concern
