Population justification: Partners in Flight estimate the total population to number 50,000-499,999 individuals (A. Panjabi in litt. 2008).

Trend justification: This species is thought to be local in its occurrence in some areas owing to deforestation (del Hoyo et al. 2004), thus its population is suspected to be in decline.
