Population justification: Subspecies argyrotis has a population of less than 50,000 individuals (Hilty and Brown 1986, Strahl et al. 1994, Strahl and Silva 1997). Subspecies albicauda and colombiana each number less than 10,000 individuals (Strahl et al. 1994). The global population consequently numbers up to 70,000 individuals (Strahl et al. 1994). This roughly equates to 45,000 mature individuals.

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction in parts of its range and the impact of hunting.
Tree cover within the range is lost at a rate of up to 5% over three generations (20.5 years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Given that the species is moreover subject to hunting, population declines may be steeper than the rate of tree cover loss suggests; tentatively, population declines are here placed in the band 1-19% over three generations.
