Great Horned Owl

Great Horned Owl key facts

Care level

Advanced

Lifespan

Up to about 29 years in the wild; the captive record is 50 years

Size

43-64cm (average 55cm; wingspan 91-153cm)

Diet

In the wild rabbits, rodents, birds and reptiles; in captivity frozen mice, day-old chicks and quail

Cage

With a wingspan reaching 1.5 m, it needs an aviary large enough to spare its feathers. Provide several perches of differing diameters to spread the load on its feet.

Temperament

It is large and powerfully footed and strikes with its talons when defending itself, becoming especially fierce in the nesting season. It suits keepers already skilled in restraining and handling raptors.

Vocalization

At night it gives a low but carrying ho-ho-hoo hoo hoo of four or five syllables. The voice travels far, so the bird is unsuited to flats and terraced housing.

Notes

Listed on CITES Appendix II, so import requires an export permit. A reliable supply of frozen food and proper raptor equipment for restraint are prerequisites.

About Great Horned Owl

One of the largest owls in the Americas, known for its ear tufts and yellow eyes. Its wide wingspan and powerful grip mean it needs a spacious aviary and an experienced raptor keeper.

7 things to know before welcoming a Great Horned Owl

1. 1A Large, Tall Aviary Is Essential

   With a wingspan of 91-153cm, this owl needs an aviary with enough width and height to spread its wings and move freely. Perches should be spaced generously to accommodate its size.

2. 2Respecting Its Powerful Grip

   Its legs and talons are extremely powerful, so caretakers need to learn proper birds-of-prey handling techniques before routine care or restraint. Approaching without experience is not advisable.

3. 3Solitary and Quiet by Nature

   This owl is naturally solitary rather than social. Some individuals grow comfortable with their keeper, but a relationship built on respectful distance suits it better than frequent handling.

4. 4Highly Adaptable Across Habitats

   Native across a wide range of the Americas, this species is known for adapting well to varied environments. Even so, keepers should maintain consistent temperature and humidity in captivity.

5. 5Plan for a Long Lifespan

   This is a long-lived bird, with wild individuals reaching around 29 years and a captive record of 50 years. Prospective keepers should plan for many years of ongoing care.

6. 6Accounting for Sharp Senses

   With large yellow eyes and acute hearing, this owl is sensitive to surrounding sounds and movement. Choose a calm aviary location away from excessive noise or foot traffic.

7. 7Prior Raptor Experience Is Assumed

   Its size, strength, and behavior are all typical of a bird of prey, making it unsuitable as a first owl or raptor. Building knowledge and experience beforehand is strongly recommended.
