Population justification: The global population size has not been formerly quantified, but the species is described as generally uncommon, although locally common (del Hoyo et al. 2007). The number of mature individuals is preliminarily estimated at fewer than 20,000.

Trend justification: The rate of habitat loss over the past 3 generations of this species is likely to fall in the range of 1-19%, and so a similar rate of decline in the population size may be suspected.
