Bird GuideOwlsFlammulated Owl

At a Glance

The soft, low-pitched hoots of this little owl can be heard (if one listens carefully) in mountain pine forests over much of the west. Seeing the bird is another matter; its variegated pattern of brown and rust makes perfect camouflage when it perches close to a pine trunk. Because it is so inconspicuous, the Flammulated Owl was long overlooked in many areas, and was considered rare until recently.

Migration & Range Maps

Strongly migratory, with North American birds going to Mexico and Central America for winter. May tend to migrate north through the lowlands in spring (when insects may be scarce at upper elevations), and south through the mountains in fall.

Habitat

Open pine forests in mountains. Nests in relatively open forest, typically of ponderosa pine, in cool and fairly dry zones such as mountains of the interior. In some areas, favors groves of aspen. Upper level of forest usually quite open, but may be brushy understory of oaks and other plants. In migration, sometimes found in dense thickets at lower elevations.

Behavior

Eggs

2-3, sometimes 4. White or creamy-white. Incubation is by female only, 21-24 days. Male brings food to incubating female at nest. Young: Female remains with nestlings for about 12 days after they hatch; male brings food for female and young. After about 12 days, female also hunts. Young leave nest by about 25 days after hatching, perch in trees nearby. At least sometimes, brood splits up after fledging, each parent tending 1-2 of the young for about another 4 weeks.

Feeding Behavior

Hunts most actively just after dark and near dawn, less in middle of night. Forages by perching and looking for insects, then flying out to catch them. May catch prey in the air or on the ground, but apparently most often takes insects from foliage, hovering momentarily and grabbing them with feet.

Diet

Large insects. Feeds almost entirely on insects, especially moths, beetles, and crickets. Also eats a few spiders, centipedes, scorpions, and other arthropods. Almost never eats vertebrates, but once proven to have eaten a shrew.

Nesting

Male hoots at night early in season to defend territory and attract a mate. In courtship, female begs, male feeds her. Nest site is in cavity in tree, usually old woodpecker hole, usually 15-40' above ground. Will also use artificial nest boxes.

Climate Vulnerability

Conservation Status

Still widespread, and common in many areas, but probably has declined in some regions. Cutting of dead trees in forest removes potential nesting sites.
