Population justification: The population has been estimated at around 2,200 individuals, based on a population density estimate of 1.1 individuals/km2 and an estimated extent of remaining habitat of 2,000km(Renjifo et al. 2016). This roughly equates to 1,467 mature individuals, placed here in the band 1,000-2,499 mature individuals.

Trend justification: This species has declined dramatically owing to habitat loss and hunting pressure. Given that protection is inadequate throughout the majority of its restricted range (even within protected areas), very rapid declines are suspected to be ongoing. An estimated 7.84% of forest within the species's range was lost between 2000 and 2010 (Renjifo et al. 2016), which is equivalent to a 25% reduction across three generations, but the rate of population decline was likely to have been higher than this due to hunting. It is projected that the species could undergo an extremely rapid population reduction in the future given increased access and hunting. The past reduction is therefore placed in the band 50-79% and the future reduction is placed in the band 80-100%.
