The great horned owl is a large "tufted" ear owl, approximately 50 cm tall. It is a mottled grey-brown with distinct grey-brown barred appearance on the breast.

Behaviour

This owl generally resides in natural areas and is common throughout Alberta.

• Occasionally out in daylight, but tends to be a silent nocturnal hunter.
• Preys on a variety of birds, mice, skunks, hares and rabbits.
• Nests in late winter.
• May defend the nest area by swooping toward the intruder. Generally, they are easily scared away, but an umbrella may be used as a deterrent.

Management

The great horned owl is our provincial bird and is protected by the Wildlife Act.

• Keep a watchful eye on small pets if owls are in the area.
• Covered kennels or exercise pens are recommended.
• Domestic bird pens may be covered with synthetic netting, available at hardware and farm stores, greenhouse and nursery supply locations.
