Population justification: The extent of suitable habitat is less than 400 km2, and even in its preferred habitat it appears to be patchily distributed, not common and hard to find. A preliminary population estimate is therefore that there may be fewer than 1,000 mature individuals (Collar and Salaman 2013), placed here in the band 250-999 mature individuals.

Trend justification: Although no trend data are available, the species is known only from within a well-protected national park, and there appears to be no reason to suspect a population decline.
