Population justification: The global population size has not been quantified. National population estimates include c. 2,900 mature individuals in Colombia (Renjifo et al. 2014), c. 10,000 mature individuals in Ecuador (Freile et al. 2018) and c. 3,300 mature individuals in Peru (SERFOR 2018). Tentatively, the population size is here placed in the band 10,000-19,999 mature individuals, but research is needed to produce a precise estimate. In Peru, the species may be more widespread and numerous than previously assumed (R. Piana and F. Angulo in litt. 2020).

Trend justification: There is no evidence that the population is in decline, although ongoing habitat destruction may pose a threat in the future.
