Population justification: The species appears to be rare and local, and is only observed singly, in pairs or small groups of up to three individuals (Renjifo et al. 2014). In Colombia, the species was found to occur at a density of 3 individuals/km² (Renjifo et al. 2014 and references therein). Assuming that this density is representative for the entire range, and furthermore precautionarily assuming that only 10% of the range is occupied to account for the species' apparent rarity (i.e. c.1,800 km²), the global population may number 5,400 individuals. This is equivalent to 3,600 mature individuals. To account for uncertainty, the population is here placed in the band 2,500-9,999 mature individuals.

Trend justification: The species is suspected to be in decline as a consequence of habitat loss and degradation. In Colombia, the species lost 5.2% of suitable habitat during the ten years prior to 2014 (Renjifo et al. 2014). Assuming that the rate of habitat loss is similar across the range, and that it is continuing at this rate to the present day and into the future, this equates to a loss of 6% over three generations (11.6 years; Bird et al. 2020). Further assuming that population declines are roughly equivalent to the rate of habitat loss, the population may be declining at <10% over three generations.
