Major Threats

Conservation Actions

The range of this species includes several Biosphere Reserves. The preservation of forests is the only way to protect this species.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it is common and somewhat adaptable with a presumed large population, and it is unlikely to be declining to qualify for listing in a more threatened category.
