Barred Owl
Barred Owl
Strix varia
At a Glance
The rich baritone hooting of the Barred Owl is a characteristic sound in southern swamps, where members of a pair often will call back and forth to each other. Although the bird is mostly active at night, it will also call and even hunt in the daytime. Only a little smaller than the Great Horned Owl, the Barred Owl is markedly less aggressive, and competition with its tough cousin may keep the Barred out of more open woods.

Behavior
Eggs
2-3, rarely 4. White. Incubation is mostly or entirely by female, about 28-33 days; male brings food to incubating female.
Young
Female may remain with young much of time at first, while male hunts and brings back food for her and for young. Age of young at first flight about 6 weeks.
Feeding 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.
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.
Nesting
Courtship involves both male and female bobbing and bowing heads, raising wings, and calling while perched close together. Male may feed female in courtship. Members of pair often call in duet. Nest site is in large natural hollow in tree, broken-off snag, or on old nest of hawk, crow, or squirrel. Rarely nests on ground. In east, often uses old Red-shouldered Hawk nest; hawk and owl may use same nest in alternate years.
Climate Vulnerability
Conservation Status
Still widespread and common, although may have declined in parts of south with loss of swamp habitat. In recent decades, has expanded range in northwest, and is now competing there with Spotted Owl.
