Population justification: Partners in Flight (2019) estimated the population to number fewer than 50,000 mature individuals, thus it is placed in the band 20,000-49,999 mature individuals here. The species is estimated to occur at densities of ~98 indiv./km² in the Sierra Tolistoque, Oaxaca, Mexico where ~30% of the global population is thought to occur (Monroy-Ojeda et al. 2018).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines, despite the current threats to the species's habitat. However the State of North America's Birds 2016 assessed the population as declining (NABCI 2016). Further information is required to ascertain the trend direction and the impact of potential threats within its range.
