The red squirrel is also a small tree squirrel, only slightly larger than the Douglas' squirrel. They occur in the montane forested portions of Wallowa, Union, Umatilla, Morrow, Malheur and Baker counties. It is a largely arboreal, forest-dwelling species and although often occupying areas vegetated by other conifers, it is associated most frequently with lodgepole pine.

Activity patterns of red squirrels are similar to those of Douglas' squirrels. Much activity is directed toward foraging, gathering and catching cones, feeding, and resting.
