The Montezuma Quail (Cyrtonyx montezumae) occurs widely from central Arizona, southern New Mexico, and western Texas to southern Mexico, inhabiting pine–oak forests, arid montane scrub, and temperate grasslands (AOU 1998). In Mexico, the species occurs as an uncommon to fairly common year-round resident in the interior from Sonora and Coahuila south across the highlands to Oaxaca (Howell and Webb 1995). It is uncommon to fairly common (in suitable habitat) at several localities in and near the Sierra Madre Occidental of western Chihuahua, including minor ranges to the east (Howell and Webb 1995, Navarro and Peterson 2007, BirdLife International and NatureServe 2014; Figure 1), but it may now be rare or extirpated locally in much of its historic range.
