Abstract:

The great gray owl, the largest Strix in North America, is the only member of its genus that breeds in both the Old and New Worlds. Primarily a bird of dense, northern boreal forests, it finds suitable coniferous habitat south into the northern Rocky and Sierra mountains and along some central Asiatic mountain chains. Although well studied in Scandinavia, less is known about this species in North America. This species account for the great gray owl, therefore, relies heavily on just a handful of North American studies, plus references to Scandinavian populations to provide the known information about the species' life history, including its distribution, migration, habitat, food habits, sounds, behavior, and breeding. The account also considers conservation and management.
