The Eastern fox squirrel is among the larger of the tree squirrels in Oregon. Its body is the typical squirrel shape. The ears are short, rounded, and without tufts. The tail is flattened and somewhat fluffy.
In Oregon, it has been found in Multnomah, Washington, Marion, Lane, Union, Clackamas, Yamhill and Baker counties, all occurring in urban areas or in association with nut orchards.
The Eastern fox squirrel is active throughout the year during daylight with its greatest activity in the early morning and late afternoon. During autumn, they are exceptionally active on the ground, scatter-hoarding nuts and acorns as they mature and ripen.
