Ear tufts are close together, long, black and rufous, and are not visible in flight. Female is darker. Superficially resembles Great Horned Owl, but is much smaller.

Long-eared Owl: Commonly occurs throughout the northern hemisphere. In North America breeds from southern Canada to New England and much of the southwest. Winters from the Midwest south to Mexico. Preferred habitats include dense vegetation close to grasslands or shrublands, as well as open forests.

Breeding and Nesting

Long-eared Owl: Two to ten white eggs are laid in an abandoned stick or cavity nest; occasionally builds its own nest. Female incubates eggs for 26 to 28 days.

Foraging and Feeding

Long-eared Owl: Eats mice, moles, ground squirrels, small birds, small snakes, and insects. An active hunter suspected of capturing most of its prey by sound due to its ability to locate mice in complete darkness; most prey is captured on the ground or in low vegetation.
