Population justification: The population size has not been quantified, but the species is described as generally uncommon (Schulenberg et al. 2007). It appears to be patchily distributed within its range (see eBird 2023). It is precautionarily suspected that the population numbers between 2,500 and 9,999 mature individuals, consisting of several small and disconnected subpopulations. These values however are of poor quality and not based on quantitative evidence, and an accurate quantification is urgently required.

Trend justification: The population trend has not been investigated. Polylepis/Gynoxys woodlands are however increasingly lost, fragmented and degraded as a consequence of human activities and livestock grazing; matrix habitat is often unsuitable for forest-dependent species (Lloyd and Marsden 2008). Microspingus alticola is strongly associated with larger patches of Polylepis forest (Sevillano-Ríos and Rodewald 2017). Consequently, on the basis of ongoing fragmentation of forests and conversion into unsuitable habitats, a continuing decline in the population size is inferred.
