Population justification: Surveys carried out in broadleaf forest in Guatemala found a density of 33-93 individuals per km²; based on this density the population in Guatemala was estimated to number 8,250-23,250 individuals (Eisermann et al. 2011a). However, the densities used in this calculation were estimated from surveys at 1,400-1,900 m, where the species is more abundant than at 900-1,300 m, and the density estimates may have been affected by the patchy nature of forest in the survey areas (see Eisermann et al. 2011a). The relative abundance in Mexico was found to be lower; surveys at El Triunfo Biosphere Reserve recorded only 0.84 individuals per km² (Secretaría de Medio Ambiente, Vivienda e Historia Natural 2011, Enríquez et al. 2013, P. Enríquez in litt. 2019). Assuming that the population in Guatemala is much larger than the population in Mexico, the global population is tentatively placed in the band of c.10,000-25,000 individuals. This roughly equates to 6,000-17,000 mature individuals. The map of sightings of this species on eBird (eBird 2019) suggests that the species occurs in either one or two subpopulations. If it were to be considered as two subpopulations, then the largest subpopulation would probably contain significantly greater than 1,000 mature individuals. Unless new information becomes available, the species is precautionarily assumed to occur in only one subpopulation.

Trend justification: The species is thought to be in moderate decline owing to habitat loss, primarily for coffee cultivation. The population trend for this species has not been directly estimated. The rate of habitat loss within the range is placed in the band 10-15% over ten years (K. Eisermann in litt. 2019). The species is precautionarily inferred to undergo a slow population decline.
