Population justification: The population size has not been quantified directly. In Colombia, the population is estimated at just over 10,000 mature individuals, forming one subpopulation (Renjifo et al. 2014). The global population is therefore preliminarily placed in the band 10,000-19,999 mature individuals. The species is described as 'uncommon' (Stotz et al. 1996).

Trend justification: The species is threatened by the loss of forests for agricultural expansion, timber extraction and mining (M. Sanchez in litt. 2013). Over the past three generations (17.4 years), 4% of forest has been lost within the range (Global Forest Watch 2020). While the species’s tolerance of degraded habitats indicates that the population may not be severely impacted by habitat loss, its preference of forest interiors for hunting of prey suggests otherwise. Precautionarily, it is suspected that the rate of population decline is faster than the rate of forest loss, amounting to up to 10% over three generations.
