Western Screech-Owl
Western Screech-Owl
Megascops kennicottii
At a Glance
Inconspicuous but locally very common is this little owl. In the varied terrain of the west, its haunts range from coastal forests in southeastern Alaska to cactus groves in the Arizona desert, and it is often found in suburban areas. Until the 1980s, Western and Eastern screech-owls were considered to belong to the same species because they look so similar; however, their voices differ, and they apparently recognize their own kind by sound.

Behavior
Eggs
2-5, sometimes 6. White. Incubation is mostly or entirely by female, averages about 26 days. Male brings food to female during incubation.
Young
Both parents bring food for young. If intruders (including humans) come too close to nest, adults may attack or may put on distraction display. Young leave nest about 4 weeks after hatching, are cared for by parents for some time thereafter.
Feeding Behavior
Forages at dusk and at night. Hunts mostly by watching from a perch and then swooping down to take prey from the ground or from foliage. Also catches flying insects in the air. Can locate prey by sound as well as by sight.
Diet
Mostly small mammals and large insects. Diet varies with habitat and region. Includes many beetles, moths, other insects, as well as spiders, scorpions, centipedes; also many small mammals, such as mice, voles, pocket gophers. Also eats small birds, lizards, snakes, frogs, fish.
Nesting
Courtship displays of male while perched include bowing, clicking bill. Male brings food to female. Mated pairs preen each other's feathers, call in duet. Nest site is in cavity in tree, pole, or giant cactus, typically in old woodpecker hole but also in natural hollows in trees. May also use old magpie nests. Sites usually 5-35' above ground.
Climate Vulnerability
Conservation Status
Widespread and common, but has declined in some areas because of habitat loss.
