Population justification: In Panama, the species is described as fairly common in suitable habitat (Ridgely and Gwynne 1989), but appears to be less common in Colombia (Renjifo et al. 2016). Based on the lower band of population density estimates of congeners, the population in Colombia is inferred to number 353 individuals (Renjifo et al. 2016). Assuming that the species occurs at a similar density in Panama, the national population there may be around 1,765 individuals; however, this may be an underestimate given that the species is described as fairly common. The overall population is here preliminarily inferred to number at least 2,118 individuals, equating to roughly 1,400 mature individuals, though this requires confirmation.
The population structure is not known.

Trend justification: Hunting, habitat loss and fragmentation are not yet major issues in this species's altitudinal range; over the past three generations (13.5 years) forest loss has been negligible (<0.5%; Global Forest Watch 2021). The population is therefore considered to be stable.
