Squirrels in Oregon: identification guide and where to start looking

1. What squirrel species live in Oregon?
Oregon's squirrel lineup includes four tree squirrels: the Western gray squirrel, Eastern gray squirrel (introduced), Douglas squirrel, and American red squirrel. Two flying squirrels (Northern and Humboldt's) are nocturnal. Ground squirrels include the California ground squirrel, Belding's ground squirrel, and the Townsend's ground squirrel. Tree squirrels are most common west of the Cascades, while ground squirrels dominate eastern Oregon.

2. Where in Oregon are you most likely to see squirrels?
Start with western Oregon's mixed conifer and oak woodlands, especially in the Willamette Valley and Coast Range. City parks like Portland's Washington Park or Eugene's Hendricks Park reliably host Western grays and Douglas squirrels. For ground squirrels, try the sagebrush steppe of eastern Oregon around the John Day Fossil Beds. In the Cascades, look for American red squirrels at mid-elevations.
3. What are the best seasons and times for squirrel sightings?
Tree squirrels remain active year-round, but early morning and late afternoon offer the best odds. Late summer and fall are prime times when squirrels gather and cache acorns and pine cones. Ground squirrels hibernate from November through February, so target spring through fall for those.

4. How can you tell Western gray squirrels from Eastern gray squirrels in Oregon?
The Western gray squirrel is the only native gray squirrel west of the Cascades. Look for its distinct silver-gray tail with white-tipped hairs. Eastern grays are more brownish and often have a reddish tint. Western grays have prominent ear tufts in winter; Eastern grays do not. Belly color: Western grays are white, Eastern grays are white but less contrast. For reliable ID, focus on the tail and ear tufts.
5. How do you identify a Douglas squirrel from an American red squirrel?
Douglas squirrels (sometimes called chickarees) are slightly larger and greenish-brown on the back with a whitish belly and rusty orange eyelids. American red squirrels are smaller, brighter reddish-brown, and have a distinct white eye ring. Both are noisy, but Douglas squirrels give a sharp, rattling call. In Oregon, Douglas squirrels are common west of the Cascades; red squirrels are found in the Cascades and east.
6. What do Oregon's ground squirrels look like?
The California ground squirrel is the most widespread. It has a mottled brown back with light and dark spots, a long bushy tail, and a whitish belly with black stripes on the sides. Belding's ground squirrel is darker with a short tail and no stripes. Townsend's ground squirrel is smaller with a narrow tail. Unlike tree squirrels, ground squirrels dig burrows and are often seen sitting upright near their holes.
7. How can you spot a flying squirrel in Oregon?
Flying squirrels are strictly nocturnal. Your best bet is to hike into old-growth conifer forests at dusk and listen for soft chirps or the rustle of gliding between trees. Use a red flashlight to avoid startling them. The Northern flying squirrel has a gray-brown back and white belly, with a flattened tail and large eyes. Humboldt's flying squirrel is similar but found in coastal forests.
8. How can you plan a squirrel watching trip in Oregon?
To find the best trails and public lands, start with the Oregon Wildlife Explorer or check local park websites. A simple pair of binoculars and a field guide will improve your odds. For more on squirrel spotting strategies, see oursquirrel identification hub.
