Taxonomy

Taxonomic note
Cyrtonyx montezumae and C. sallei (del Hoyo and Collar 2014) were previously lumped as C. montezumae following Sibley and Monroe (1990, 1993), but prior to that had been treated as two species in Collar and Andrew (1988).

Population justification: The total population (including C. sallei) may number over 500,000 birds (del Hoyo et al. 1994).

Trend justification: This species has had stable population trends over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007). Note, however, that these surveys cover less than 50% of the species's range in North America.
