Found in North America, Europe, and Asia, the long-eared owl (Asio otus) often resides in the deserted nests of similarly sized birds, such as hawks, ravens, or magpies. The diet of these medium-sized true owls consists primarily of small mammals they find in open land areas.
After a courtship that involves aerial displays and calls by males, most long-eared owls form monogamous pairs.
