Population justification: Previously, the population was estimated to number 4,200 individuals in total, based on density estimates of 3.6 individuals/km2 (Renjifo et al. 2014), which roughly equals 2,800 mature individuals. However, this may have been a underestimate, with the species known to have differentiating occupancy rates based on elevation (Escudero-Páez et al. 2018). Recent density estimates are as such higher at 20.6 individuals/km2, with a maximum density of 56 individuals/km2 recorded in the department of Tolima. Assuming that the species only occupies parts of its mapped range, the population may therefore number as high as 16,000-44,000 individuals, converted to 11,000-29,000 mature individuals. However, precautionarily assuming that population size is closer to the lower estimate, it may be tentatively placed in the band of 10,000-19,000 mature individuals. Based on the high degree of fragmentation of its habitat, it is also likely that the species forms several small, disjunct subpopulations.
Trend justification: The population is though to be undergoing a slow decline, mainly due to the loss and degradation of its habitat, but the rate of decline has not been quantified directly. Global Forest Watch (2020) measured the forest loss within this species’s range to be <5% over 3 generations (14.1 years; Bird et al. 2020), with the assumption that habitat loss is continuing at the same rate. Despite ready tolerance to degraded habitats and occurrence in agricultural areas, in parts of its range the species is additionally hunted for food (Renjifo et al. 2014). As a consequence, it is inferred that the species is declining at <10% over three generations.
