Barred Owl

Strix varia

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.

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.
Family	Owls
Habitat	Woodlands, wooded river bottoms, wooded swamps. Favors mostly dense and thick woods with only scattered clearings, especially in low-lying and swampy areas. Most common in deciduous or mixed woods in southeast, but in north and northwest may be found in mature coniferous trees.

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.

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.

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.

How Climate Change Will Reshape the Range of the Barred Owl

Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.

Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
