The Spotted Owl is a medium-sized, dark-eyed owl found in select forested regions of Arizona, where two subspecies occur: the Mexican Spotted Owl (S. o. lucida) in central and southeastern mountain ranges, and the California Spotted Owl (S. o. occidentalis), which is only a rare vagrant in the state. The Mexican Spotted Owl, listed as Threatened under the U.S. Endangered Species Act, inhabits mature mixed-conifer and pine–oak forests, as well as steep rocky canyons, often in isolated “sky island” mountain ranges. It is recognized by its dark brown plumage heavily marked with irregular white spots, rounded head without ear tufts, and dark eyes. This nocturnal hunter feeds primarily on small mammals such as woodrats and mice but will also take birds, reptiles, and large insects. Breeding occurs from late winter to early summer, with pairs nesting in tree cavities, cliff ledges, or abandoned raptor nests. In Arizona, populations have declined due to habitat loss from logging, wildfires, and drought. Conservation efforts focus on protecting old-growth forest habitat, reducing severe wildfire risk, and monitoring population trends to ensure the persistence of this secretive species in the state’s high-elevation forests and canyonlands.
