Population justification: The known population numbers only 24 territories; however, an extrapolation of habitat preferences across the reserve and adjacent suitable areas, based on contour maps of the eastern and south-eastern slopes of the Páramo del Sol massif, gives an estimated known range size of potentially only 5.8 km2 and thus a cautious estimate of 57-156 territories. Each territory refers to a singing adult male, so this figure does not necessarily translate to an estimate of the number of pairs, and hence there are estimated to be fewer than 250 mature individuals, with the population placed in the band 50-249 mature individuals. This equates to 75-374 individuals in total, rounded here to 70-400 individuals.
Trend justification: The species's population is considered to be undergoing a decline owing to ongoing forest clearance, primarily for agricultural expansion.
