Spotted Owl
Strix occidentalis · also called spotted owls, northern spotted owl
Deep within one of the remaining stretches of Pacific Northwest old-growth forest, a spotted owl perches quietly, dark eyes watching an approaching observer without much apparent concern, a species whose need for exactly this kind of ancient forest structure once reshaped an entire region’s approach to logging.
Overview
The spotted owl, Strix occidentalis, is a forest owl native to old-growth and mature forest across a range of the western United States, including the Pacific Northwest and parts of the Southwest. Its strict dependence on complex old-growth forest structure, central role in major forest conservation policy debates, and mounting competition from the range-expanding barred owl make it one of the most conservation-significant birds of prey in North America.
A species that reshaped forest policy
Few birds have influenced land management policy as directly as the spotted owl, whose specific need for old-growth forest structure turned its conservation into one of the defining environmental debates of recent decades.
Status
Near Threatened, having declined significantly due to historical old-growth forest loss and increasing competition and hybridisation from the range-expanding barred owl.
Spotted Owl: common questions
Why did the spotted owl become such a significant conservation issue?
This species depends on the complex structure of old-growth forest, conditions that take many decades or longer to develop, and as historical logging removed large areas of old-growth forest across the Pacific Northwest, the resulting conflict between protecting spotted owl habitat and continuing timber harvest became one of the defining forest policy debates of the late 20th century.
How has the barred owl affected the spotted owl?
The barred owl has expanded westward into spotted owl habitat in recent decades, competing directly for the same resources and sometimes hybridising with the spotted owl, a combination of pressures that has contributed to further population declines even in areas where old-growth habitat protections are already in place.
How can you identify a spotted owl?
Look for dark brown eyes and a rounded head without ear tufts, combined with the species' generally less wary behaviour around people, features that together help distinguish it from several other owl species that may share similar old-growth forest habitat.
Where does the spotted owl live?
This species is native to old-growth and mature forest across a range of the western United States, including the Pacific Northwest and parts of the Southwest, depending closely on the specific complex forest structure that develops only in long-undisturbed woodland.
