Population justification: The species is rare and local. A population size of 1,500-6,000 was estimated by Collar et al. (1992). This is roughly equivalent to 1,000-4,000 mature individuals.
Trend justification: This species's population is suspected to be decreasing slowly, in line with rates of habitat loss and degradation within its range.
