Population justification: Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction. Montane forests in Chiapas have been reduced to less than 25% of their original area with an annual deforestation rate of at least 2.7% over the last 30 years (Cayuela et al. 2006).
