Population justification: The global population size has not been formally quantified, but this species is described as 'rare' (Stotz et al. 1996), thus the population is preliminarily placed in the band for 10,000-19,999 mature individuals, assumed to equate to c.15,000-30,000 individuals in total. Given the species's patchy distribution, it is assumed that there are multiple sub-populations numbering no more than 1,000 mature individuals each.
Trend justification: Data on population trends are lacking, but the species is thought to be in decline owing to continued habitat loss and degradation within its range.
