Squirrels in Oregon: where to look and what signs to watch for

1. Where are squirrels most likely found in Oregon?

Squirrels are widespread, but each species favors specific habitat. The Western gray squirrel sticks to oak woodlands in the Willamette Valley and southwestern Oregon. The Douglas squirrel prefers conifer forests in the Cascades and Coast Range. California ground squirrels live in open, grassy areas east of the Cascades. For reliable sightings, visit parks with large oaks like Silver Falls State Park or urban areas such as Portland's Forest Park.

2. What time of day are squirrels most active?

Squirrels are most active in the early morning and late afternoon, especially during spring and fall. In hot summer weather, they often shift activity to dawn and dusk. Winter activity is reduced, but on mild days they may forage midday. The best odds for watching natural behavior are between 7-10 am and 4-6 pm, when squirrels are busy gathering food.

3. How can I identify squirrel tracks and signs?

Look for four-toed front tracks and five-toed hind tracks in mud or snow. Hind tracks are longer (about 2-3 inches). Squirrel signs also include scratched bark on trees (from climbing), gnawed pine cones with the scales stripped off, and leafy dreys about 12-20 inches across high in tree forks. Listen for chattering calls, which often signal a squirrel's presence before you see it.

4. What squirrel species live in Oregon?

Oregon hosts four main squirrel species. The Western gray squirrel is the largest, with a long bushy tail and gray body. The Douglas squirrel is smaller, reddish-brown, and very vocal. The California ground squirrel lives in colonies and hibernates in winter. The northern flying squirrel is nocturnal and rarely seen, but lives in mature conifer forests across the state.
