    The Mexican Spotted Owl relies on cool and shady habitats in the southwest. The birds forage primarily on small rodents. Any climatic disturbance that would alter the distribution and phenology of plants within the forests, could alter the landscape in a negative way for both spotted . The Northern Spotted Owl, Strix occidentalis caurina, is the only subspecies of Spotted Owl found in Canada. This subspecies is distributed from the southwest mainland of British Columbia through western Washington, western Oregon and the coast ranges of California to San Francisco Bay (Figure 1). Although the current range is similar to the historic range, the distribution and abundance of.

    The spotted owl (Strix occidentalis) is a medium-sized owl that inhabits thickly wooded canyons, woodlands, and forests of Western North America. It has a round head, dark eyes, and dark brown coloring with whitish spotting on the head and back, and white mottling on the abdomen and breast, hence, the name spotted owl. Typical of birds of prey, the female is slightly larger than the male. Distribution and Population. The Spotted Owl is found in North America, from southwestern British Columbia to Mexico. The range of the caurina subspecies of the Spotted Owl extends from the southwestern mainland of British Columbia through western Washington, western Oregon, and the coastal ranges of northern California.
