Population justification: The global population size has not been quantified, but this species is described as extremely local and uncommon within its small range (del Hoyo et al. 2005), thus it 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.
Trend justification: This species's population is inferred to be in decline owing to habitat destruction (del Hoyo et al. 2005), and is suspected to undergo a moderately rapid reduction over the next three generations.
