Population justification: The population density was estimated at 10-18 pairs per km², but could be as high as 100-200 pairs per km² (Renjifo et al. 2014). Thus, the number of mature individuals at each site occupied by the species is likely very high. However, considering the species's strict habitat requirements and apparent preference for extremely steep terrain, occupied sites are very localised within the species's Extent of Occurrence. Thus, the global population is best placed in the band 2,500-9,999 mature individuals (Renjifo et al. 2014), equating roughly to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: The species's population is suspected to be declining based on current rates of forest loss within its restricted range (Salaman et al. 2003). The likely rate of population decline has not been estimated.
