Population justification: Surveys carried out in 1998-1999 found high densities in both primary forest and adjacent secondary habitats. Low densities were also recorded in secondary habitats that were isolated from primary forest. As such, the population estimate was revised to take into account both higer abundance in key habitats, and presence in larger areas of secondary habitat, resulting in an increased estimate of 18,900-43,800 individuals, roughly equivalent to 13,000-29,000 mature individuals.

Trend justification: Despite this species's tolerance of secondary habitats, moderate population declines are suspected to be continuing, as both primary and secondary forest habitats are being affected by encroachment and fragmentation throughout its range.
