Population justification: Based on population densities of congeners (S. stilesi and rodriguezi) the population size has been estimated at 4,965-23,170 individuals (Renjifo et al. 2014 and references therein). This equates to 3,300-15,500 mature individuals.The population structure has not been assessed, but based on observational records (eBird 2021) it is conceivable that the species forms several small subpopulations.

Trend justification: The species's population is suspected to be in decline owing to the loss, fragmentation and degradation of suitable habitats primarily through continued deforestation and intermittent fires. Habitat loss has been low in the past; it is estimated that between 2000 and 2010 the species lost a total of 1.9% of its habitat (Renjifo et al. 2014). Tree cover loss over the past ten years has been similarly low, amounting to 1% over this period (Global Forest Watch 2021). In addition to forest loss, the species is also affected by the degradation of páramo grasslands (Renjifo et al. 2014). Assuming that the rate of population decline is roughly equivalent to the rate of habitat loss and degradation, the population decline is tentatively placed in the band 1-9% over ten years.
