Population justification: The population density has been assessed in various parts of the range: In the Alto Quindió-Acaime Reserve, 1.5-6 individuals were found along 10-km transects, in Ucumarí Regional Park it occurs at a density of 0.8 individuals/ha, while in Caldas a density of 0.9 individuals/km2 were estimated (Renjifo et al. 2014 and references therein). Based on these values, and assuming that one-third of the available habitat is occupied, the population was estimated at roughly 117,000 individuals (Renjifo et al. 2014). This is equivalent to around 78,000 mature individuals. However, this value may well be an overestimation (Renjifo et al. 2014) and therefore, the population is here tentatively placed in the band 20,000-49,999 mature individuals, though this requires confirmation.
Trend justification: The population is suspected to be declining slowly, in line with rates of habitat loss within its range. Within the range, tree cover is lost at a rate of up to 2% over three generations (12.2 years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The rate of habitat loss is given as 6.25% over ten years (Renjifo et al. 2014), which equates to 7.6% over three generations. Given the species' apparent tolerance of degradation and disturbance, the rate of population decline is unlikely to exceed the rate of habitat loss; it is here tentatively placed in the band 1-9% over three generations.
