American Barn Owl
American Barn Owl
Tyto furcata
At a Glance
With its ghostly appearance, rasping shrieks, and habit of roosting in such places as church belfries, the American Barn Owl has attracted much superstition. However, it is really a good omen for farmers who find it in their barns, for it preys chiefly on mice and rats. Discovered in its daytime retreat, the American Barn Owl bobs its head and weaves back and forth, peering at the intruder. At night, it is often heard calling as it flies high over farmland or marshes. One of the most widespread of all landbirds, found on six continents and many islands.

Behavior
Eggs
Usually 3-8, sometimes 2-12 or even more. Whitish, sometimes becoming nest-stained. Incubation is by female only, 29-34 days; male brings food to female during incubation.
Young
Female remains with young at first and broods them while they are small; male brings food, female feeds it to young. After about 2 weeks, female hunts also. Age of young at first flight roughly 55-65 days. Young return to sleep at nest or nearby for several more weeks. 1-2 broods per year, sometimes 3.
Feeding Behavior
Hunts at night, seldom by day. The American Barn Owl seeks prey mostly by flying low over open ground, watching and listening; sometimes hunts by flying down from a perch. Has excellent vision in low light levels, and its hearing is so precise that it can strike prey in total darkness.
Diet
Mostly rodents. The American Barn Owl feeds heavily on voles; it also takes various kinds of mice, small rats, shrews, young rabbits, and other mammals. Eats minimal numbers of birds, lizards, insects, rarely frogs, or even fish.
Nesting
In courtship, the male American Barn Owl performs display flight, including loud wing-claps; the male feeds the female. Nest: Uses sites in caves and hollow trees, as well as many artificial sites such as barn lofts, church steeples, abandoned houses, dry wells, crevices under bridges, and nest boxes. Where no existing cavities are available, we will dig holes in dirt banks. No real nest built, but will arrange debris into a crude depression.
Conservation
Conservation Status
In recent decades, the American Barn Owl has declined slightly in some regions, drastically in others, including the Midwest and Northeast. Numbers are apparently stable or increasing in a few sites. It may be helped in some areas by the provision of nest boxes.
