However, genetic testing reveals very early divergence (likely at or near their ancestor's entry to North America) between spotted and barred owls. The spotted owl has been hypothesized to be within a superspecies with the barred owl. The barred owl is roughly intermediate in size between the larger Ural and the smaller tawny owl, but the structural features of its relatively short and decurved claws more so resemble the tawny species as does their dietary and habitat ecology. The species was named due to the varied directions the dusky markings take on their underside. The barred owl was first described by Philadelphia naturalist Benjamin Smith Barton in 1799. Basics Īlthough previously considered a subspecies of barred owl, the fulvous owl is now considered a distinct species. In response, biologists have recommended culling operations to mitigate the negative effect of the barred on the spotted owl species. Evidence shows the assorted threats posed by the invading barred species are only increasing. As a result of the barred owl's westward expansion, the species has begun to encroach on the range of the related and threatened spotted owl ( Strix occidentalis). Barred owls have typical nesting habits for a true owl, tending to raise a relatively small brood often in a tree hollow or snag (but sometimes also in other nesting sites) in forested areas. īarred owls are brown to gray overall, with dark striping on the underside. Their diet consists mainly of small mammals, but this species is an opportunistic predator and is known to prey upon other small vertebrates such as birds, reptiles, and amphibians, as well as a variety of invertebrates. Mature forests are their preferred habitat, but they can also acclimate to various gradients of open woodlands.

Barred owls are largely native to eastern North America, but have expanded their range to the west coast of North America where they are considered invasive. A member of the true owl family, Strigidae, they belong to the genus Strix, which is also the origin of the family's name under Linnaean taxonomy. The barred owl ( Strix varia), also known as the northern barred owl, striped owl or, more informally, hoot owl or eight-hooter owl, is a North American large species of owl.
