This species of owl nests on the ground, building a scrape on top of a mountain or rock. Gravel bars and abandoned eagle nests may be used. The female scrapes a small space prior to spawning.

Both the male and the female defend the nest and their young from predators, sometimes disturbing screens. This powerful bird relies primarily on lemmings and other small rodents for food during the breeding season, but in times of low prey density or during the ptarmigan nesting period, they may change in favor of young grouse. They are opportunistic predators and prey can vary greatly, especially in the winter. They eat a variety of small mammals such as mice and rats, prairie deer, but get larger prey, often found on traplines for food. Some of the larger mammal prey includes rabbits, muskrats, marmots, squirrels, rabbits, raccoons, prairie dogs, mice, moles, and entrapped furbearers. Prey Birds include ptarmigan, ducks, geese, shorebirds, pheasants, partridges, coots, grebes, gulls, birds and birds of prey, including other species of owls.

If you eat large prey into small pieces, pellets will not occur. During the breeding season, the owls regularly defend their nests against arctic foxes, ravens and rapid flight Jaegers and dogs, gray wolves and birds of prey animals. Males defend the nest guard near, while the female incubates the eggs and young larvae.
