An endemic species in western North America, the Spotted Owl is a nocturnal bird that occurs in a variety of hardwood and coniferous, old-growth forest habitats, preferably near water sources. It feeds on small mammals and birds and typically leverages cavities found in trees, deadwood and snags for its nests instead of constructing its own.
The Spotted Owl migrates in the winter, most often to recently burnt areas where there is typically greater food availability. Additionally, it is a monogamous and long-lived species with an average annual survival rate of over 80% for adults.
