Justification of Red List category
This species's range and abundance have been recently studied, and it has been found to be more widely distributed and commoner than previously thought (Collar et al. 1992). It is no longer considered to have a small range and is found within  large areas of intact primary forest. Its presence has been confirmed at more than 10 locations, and it is suspected to be undergoing only slow rates of population decline. For these reasons, it has been downlisted to Least Concern, as it can no longer be considered to approach the thresholds for Vulnerable under any of the IUCN criteria.

Population size:

Population trend: Decreasing

Extent of occurrence (breeding/resident): 186,000 km2
