Family

Description

7-7 1/2" (18-19 cm). A sparrow-sized owl. Small round head and long, finely barred tail that is often cocked at an angle. Varying shades of brown with fine buff spotting above; buff-white with bolder brown streaks below. 2 white-edged black spots at back of neck suggest eyes.

A series of mellow whistles on 1 pitch. Also a thin rattle around the nest.

Habitat

Open coniferous forests or mixed aspen and oak woods; dense canyon growth.

Range

Resident from southeastern Alaska southward throughout most of West.

Discussion

This small owl sometimes hunts by day, attacking birds even larger than itself. In spring the male is conspicuous, uttering a staccato whistle every few seconds while flicking his long tail upward and sideways. In response, the small forest birds sound an excited alarm, scolding and mobbing this tiny owl, just as they would any larger owl.

Nesting

3-6 white eggs in an abandoned woodpecker hole.
