Great Horned Owl


IUCN Conservation Status: Least Concern

With its long, earlike tufts, intimidating yellow-eyed stare, and deep hooting voice, the Great Horned Owl is the quintessential owl of storybooks. This powerful predator can take down birds and mammals even larger than itself, but it also dines on daintier fare such as tiny scorpions, mice, and frogs. It’s one of the most common owls in North America, equally at home in deserts, wetlands, forests, grasslands, backyards, cities, and almost any other semi-open habitat between the Arctic and the tropics.

Keys to identification Help

Typical Voice
  • Size & Shape

    These are large, thick-bodied owls with two prominent feathered tufts on the head. The wings are broad and rounded. In flight, the rounded head and short bill combine to create a blunt-headed silhouette.

  • Color Pattern

    Great Horned Owls are mottled gray-brown, with reddish brown faces and a neat white patch on the throat. Their overall color tone varies regionally from sooty to pale.

  • Behavior

    Great Horned Owls are nocturnal. You may see them at dusk sitting on fence posts or tree limbs at the edges of open areas, or flying across roads or fields with stiff, deep beats of their rounded wings. Their call is a deep, stuttering series of four to five hoots.

  • Habitat

    Look for this widespread owl in woods, particularly young woods interspersed with fields or other open areas. The broad range of habitats they use includes deciduous and evergreen forests, swamps, desert, tundra edges, and tropical rainforest, as well as cities, orchards, suburbs, and parks.

Similar Species

Great Horned Owls are the largest common owl in North America. Great Gray Owls of northern North America are diurnal, with a larger, grayer head and without ear tufts. Barred Owls are slightly smaller than Great Horned Owls, with dark eyes and without ear tufts. Barn Owls are smaller and much paler than Great Horned Owls, often appearing all white when flying at dusk. They have a unique, heart-shaped face and lack ear tufts. The Great Horned Owl’s deep, off-rhythm hooting is also unlike other North American owls and fairly easy to recognize.

Regional Differences

Great Horned Owls vary in color tone across their range: birds from the Pacific Northwest tend to be dark sooty; individuals across the Southwest are paler and grayer; and birds from subarctic Canada can be almost white.

Backyard Tips

Consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on our Attract Birds pages. You'll find plans for building a nest box of the appropriate size on our All About Birdhouses site.
