Description
The Barred Owl (Strix varia) is a large typical owl native to North America. Best known as the Hoot Owl for its distinctive call, it goes by many other names, including Eight Hooter, Rain Owl, Wood Owl, and Striped Owl. It has a pale face with dark rings around the eyes, a yellow beak and brown eyes. It is the only typical owl of the eastern United States which has brown eyes; all others have yellow eyes. The upper parts are mottled gray-brown. The underparts are light with markings; the chest is barred horizontally while the belly is streaked vertically. The legs and feet are covered in feathers up to the talons. The head is round and lacks ear tufts, a distinction from the slightly smaller Short-eared Owl, which favors more open, marginal habitats.



Habitat

A nocturnal bird. Hides in dense foliage during the day, usually high up. May also roost on a branch close to a broad tree-trunk, or in a natural tree hole. May be very aggressive when defending a nest. Breeding habitats are dense woods across Canada, the eastern United States, and south to Mexico; in recent years it has spread to the northwestern United States, having gradually spread farther south in the west.
Voice

A loud barking hoo, hoo, hoo-hoo; hoo, hoo; hoo, hooo-aw! and a variety of other barking calls and screams.

Diet
Mostly small mammals. Eats many mice and other small rodents, also squirrels (including flying squirrels), rabbits, opossums, shrews, other small mammals. Also eats various birds, frogs, salamanders, snakes, lizards, some insects. May take aquatic creatures such as crayfish, crabs, fish.
Behavior: Hunts by night or day, perhaps most at dawn and dusk. Seeks prey by watching from perch, also by flying low through forest; may hover before dropping to clutch prey in talons. Like many other owls, coughs up pellets of its prey.

Reproduction

The Barred Owl's nest is often in a tree cavity, often ones created by pileated woodpeckers; it may also take over an old nesting site made previously by a red-shouldered hawk, cooper's hawk, crow, or squirrel. It is a permanent resident, but may wander after the nesting season. If a nest site has proved suitable in the past they will often reuse it as the birds are non-migratory. In the United States, eggs are laid from early-January in southern Florida to mid-April in northern Maine, and consist of 2 to 4 eggs per clutch. Eggs are brooded by the female with hatching taking place approximately 4 weeks later. Young owls fledge four to five weeks after hatching. These owls have few predators, but young, unwary owls may be taken by cats. The most significant predator of Barred Owls is the Great Horned Owl.[ The Barred Owl has been known to live up to 10 years in the wild and 23 years in captivity.
Did you know?
The belly feathers of some Barred Owls are pink. This coloring may be the result of eating a lot of crayfish. A barred owl's right ear is higher than its left ear. Hearing from two different angles helps it pinpoint the location of prey.
