The CFPO is a small owl (6.5 inches) that reaches the northern end of it's range in Southern Arizona. It is locally common in parts of Sonora (esp. in the south), but is often very localized. Habitat for the CFPO in the northern 2/3 of the state is patchy. Historically in Arizona the CFPO inhabited areas from the Phoenix area south and west, and from Tucson in the east to beyond Ajo in the west. As of 2011 they are mostly extirpated from the state outside of Organ Pipe, the Tohono O'odham Nation, and the Altar Valley Southwest of Tucson.
