Great Horned Owl

Bubo virginianus
This owl is named for the feather tufts on the head that resemble horns. A large bird may exceed 60 cm in length. The coastal great horned owl is brownish to grey in colour with a barred underside, and prominent yellow eyes. Great horned owls prey upon a wide variety of small to medium-sized birds and mammals. Great horned owls use tree branch nests of other birds. Occasionally nests are found in tree cavities, on ledges, and in buildings. Conservation includes limiting the use of pesticides and conserving large trees and other nesting habitat. Known nest sites should be protected from disturbance.
