Distribution and habitat

Its breeding habitat is dense woods across Canada, the eastern United States and south to Central America; in recent years it has spread to the western United States. The Barred Owl's nest is often in a tree cavity; it may also take over an old nesting site used by a crow or squirrel. It is a permanent resident, but may wander after the nesting season.

In recent studies, suburban neighborhood has been proving ideal for the barred owls. Using transmitters, the scientist found that their population actually increased faster in the suburban setting then those in the old growth forest. So far, the only main danger to the owls are moving cars that it runs into. But the new offsprings offset that death due to the impacts from cars and disease.[1] “Suburbia” redirects here. ... Old growth forest, also called primary forest, ancient forest, virgin forest, primeval forest, frontier forest or ancient woodland (in the UK), is an area of forest that has attained great age and so exhibits unique biological features. ...


Description

The adult is 44 cm long with a 112 cm wingspan. It has a pale face with dark rings around the eyes, a yellow bill and brown eyes. It is the only typical owl of the eastern United States which has brown eyes; all others have yellow eyes. The head is round and lacks ear tufts, a distinction from the Short-eared Owl. The upper parts are mottled gray-brown. The underparts are light with markings; the chest is barred horizontally while the belly is streaked lengthwise. The legs and feet are covered in feathers up to the talons.[2] Binomial name Asio flammeus (Pontoppidan, 1763) The Short-eared Owl (Asio flammeus) is a species of typical owl (family Strigidae). ...


Behavior and ecology

Barred Owls may be partly responsible for the recent decline of the Northern Spotted Owl, native to Washington, Oregon, and California. Since the 1960s, Barred Owls have been expanding their range westward from the eastern US, perhaps because manmade changes have created new suitable habitat in the west.[1] When Spotted Owls and Barred Owls share the same environment, the latter are generally more aggressive and outcompete the former, leading to decreased populations of the native owls.[2] Image File history File links Size of this preview: 522 × 599 pixelsFull resolution (1205 × 1383 pixel, file size: 502 KB, MIME type: image/jpeg) Barred Owl on the Hontoon Dead River, near Blue Spring State Park. ...

Feeding habits

The diet of the Barred Owl consists mostly of mice of many species, but it also feeds on rabbits, chipmunks, foxes, possums and also birds such as grouse and doves.

The Barred Owl hunts by waiting on a high perch at night, or flying through the woods and swooping down on prey. It generally hunts near dawn or dusk, though it may also hunt on cloudy days. It may fly even in full daylight when disturbed. Of the North American owls, it is the species most likely to be active during the day, especially when raising chicks.[2] Predator and Prey redirect here. ...

Vocalization

When agitated, this species will make a buzzy, rasping hiss. The usual call is a series of eight accented hoots ending in oo-aw, with a downward pitch at the end. It is noisy in most seasons. It calls sometimes during the day, but generally at night. This owl may be displaced from more open woods by the Great Horned Owl. Hiss may be a phonetic element of a sibilant consonant, or of a lisp a verb close in meaning to whisper a noise characteristic of some snakes, or a different noise made for example by a cat an onomatopeic word for some noises, such as the release of air brakes...
