Cool Facts

Things you didn't know about the Barn Owl

01

Barn Owls have asymmetrical ear openings (one higher than the other) which let them pinpoint prey by sound in total darkness.

02

They produce a chilling raspy scream rather than the typical hoot. Most 'haunted barn' folklore traces to Barn Owl calls.

03

A single Barn Owl pair can take 1,000+ rodents per year. They're widely used in farm rodent control.

How to bring the Barn Owl to your yard

Barn Owls take readily to large open-fronted nest boxes mounted high in barns or on poles. They're a farm and ranch favorite.

Box placement

Mount a large Barn Owl box 12–25 ft up inside a barn, on a tall post, or under a high eave. They like large dark cavities.

Food

Rodents, they catch their own. Maintaining a no-pesticide farm increases the rodent population they need.

Cover & landscaping

Open hunting ground (pasture, hayfield, marsh) within ¼ mile of the nest.

Competitors

European Starlings will harass; they can be excluded by entrance size and design.

Avoid

Don't use rodenticides, Barn Owls are extremely vulnerable to secondary poisoning.
