Strix varia
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. |
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.
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.

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.
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.
More than 50 years after the first sighting, the best explanation for the infamous cryptid might be a nocturnal bird of prey. Audubon investigates.
It's probably a Mourning Dove. Here's the difference between their calls.
Cleaning up poisons killing Northern Spotted Owls is just one challenge the state faces. A conservation fund built from cannabis taxes could help.
The Bureau of Land Management has released a leasing plan to sell out the heart of the Arctic Refuge to oil companies.
