Population justification: The species can be locally common (Heindl et al. 2020). In 1992 the population was suspected to number more than 2,000 mature individuals and to be declining. As there are no recent estimates, the population is tentatively placed in the band 1,000-2,499 mature individuals.
Trend justification: The population trend has not been directly quantified. Páramo grassland and high-altitude forests are burned and cleared for conversion into livestock pastures and agricultural fields, lowering the treeline and causing habitat loss and fragmentation (Tinoco et al. 2009). The species is not found in pastures and agricultural land (Tinoco et al. 2009), and as such the ongoing conversion of its habitat is inferred to cause a slow continuing decline.
