Abstract:

Widely distributed through North America, the barred owl is a resident of deep forests, including swamp, riparian, and upland habitats. In the twentieth century, it has expanded its range north and west through the boreal forest, and south to northern California. Range expansion into the Pacific Northwest has brought the barred owl into contact with the closely related spotted owl (Strix occidentalis). The more aggressive barred owl has been known to displace and hybridize with the spotted owl, a further threat to that already endangered species. This species account explores what is know about the distribution, systematics, migration, habitat use, food habits, sounds, behavior, breeding ecology, demography and populations of the barred owl. Management and priorities for future research are also discussed.
