Population justification: Inside protected areas, the population density ranges from 10.8 to 18.4 individuals/km2 in mature forest; the species can reach exceptionally high densities of 70-100 individuals/km2 (Kattan et al. 2014; Renjifo et al. 2014 and references therein). Outside of protected areas the population density was found to be much lower, with roughly one family group (consisting on average of 3-4 individuals) per km transect (Renjifo et al. 2014 and references therein).
Despite its ability to move through secondary habitats between forest patches (Kattan et al. 2014), it is assumed that the species forms several disjunct subpopulations, given the fragmentation of the range. Subpopulation estimates include 700 individuals (equating to c.460 mature individuals) in and around Otún-Quimbaya Flora and Fauna Sanctuary, 67 individuals in Yotoco (equating to c.45 mature individuals), 150 individuals in Bremen y Barbas Natural Regional Park (equating to c.100 mature individuals), and an unknown number in other parts of the range (Renjifo et al. 2014).
It is therefore estimated that the total population numbers less than 2,500 mature individuals (Renjifo et al. 2014), placed here in the band 1,000-2,499 mature individuals.
Trend justification: Forested habitat within the range has been lost at a rate of 12% over three generations (23.1 years; Global Forest Watch 2020). This is likely exacerbated by additional impacts of forest degradation and fragmentation. The species is furthermore threatened by hunting and has already been extirpated from localities in Cauca, Dagua and Patía (Renjifo et al. 2014). Population declines are therefore precautionarily placed in the band 20-29% over three generations; it is assumed that declines go on at a similar rate into the future.
