Spotted Owl

The Spotted Owl is a large, dark, richly patterned owl of mature and old-growth forests in western North America. It has a round head without ear tufts, deep brown plumage marked with round white spots (rather than the streaking typical of many owls), and distinctive dark brown eyes rather than the yellow eyes of most owls.

Three recognized subspecies - Northern, California, and Mexican Spotted Owl - vary subtly in tone and range but share the same gentle, soulful expression created by the dark eyes and rounded facial disc.

The species became a national symbol of the old-growth logging controversy in the Pacific Northwest during the late twentieth century, and it remains a key indicator species for the health of mature forest ecosystems.

Key Field Marks

• Dark brown eyes (unusual among North American owls, most of which have yellow eyes)
• Chocolate-brown plumage with round white spots on the head, back, and underparts
• No ear tufts; round head
• Relatively tame, often allowing close approach

Similar Species

• Barred Owl, a close relative that has expanded into Spotted Owl range and hybridizes with it, is paler grayish-brown with vertical streaking on the belly (rather than spotting) and horizontal barring on the chest; competition and hybridization with Barred Owls is a major conservation concern.
• Great Horned Owl is larger with prominent ear tufts and yellow eyes.

Spotted Owls depend on structurally complex, mature and old-growth forest with dense multi-layered canopy, large trees, and abundant snags or cavities for nesting. The Northern subspecies occurs from British Columbia south through Washington, Oregon, and northern California; the California subspecies inhabits the Sierra Nevada and coastal ranges of California; and the Mexican subspecies ranges through the southwestern US and Mexican highlands.

Most individuals are non-migratory, maintaining large home ranges within suitable old-growth habitat year-round, though some higher-elevation populations shift to lower ground in winter.

Behavior

Strictly nocturnal, Spotted Owls roost quietly in dense canopy by day and are famously tame, sometimes allowing observers to approach closely. Pairs maintain large, stable territories and mate for life.

Voice

The common call is a series of four deep, resonant hoots, often rendered as "who... who-who... whoo," along with a rising contact bark. Pairs frequently duet.

Feeding

Flying squirrels and woodrats are primary prey across much of the range, supplemented by other small mammals, birds, and insects, captured by dropping from a perch in dense forest onto prey below.

Nesting & Breeding

Spotted Owls nest in tree cavities, broken-top snags, or old stick nests within old-growth stands, typically laying 2-3 eggs. Low reproductive rates and dependence on old-growth structure make the species highly sensitive to habitat loss.
