The Wyoming ground squirrel is a medium-sized ground squirrel without spots, stripes, or splotches. The dorsal pelage is grayish with a slight buffy wash. In the field, it appears distinctly more yellowish than other ground squirrels that it might be confused with. The tail is usually longer, as well. This ground squirrel is found in southeastern Oregon and emerges from hibernacula in the spring and by late July has again entered torpor. During the active season, individuals usually become active within an hour after sunrise. Photo by Andrew Hoffman, Flickr

The golden-mantled ground squirrel doubtlessly is the most distinctively marked ground squirrel in Oregon; a white stripe bordered on both sides by a black stripe extends from the shoulder to the hip. From nose to nape above the eye, the head is russet. The back between the stripes is grizzled dark grayish-brown becoming less grizzled on the rump; lateral to the stripes the color grades to a light buffy-gold on the venter. The face, shoulders, front legs, and feet are a bright orangish-gold. This ground squirrel occupies the east slope of the Cascade Range and most of central Oregon, and…

Merriam's ground squirrel is one of the two small gray ground squirrels in Oregon without stripes or spots. Most of the geographic range of this squirrel is in Oregon, where it occurs south and east of a line connecting Huntington, North Powder, Maupin, Warm Springs, Bend, and Fort Rock, Summer Lake, and Plush. This species does not occur south of the North Fork Owyhee River in Malheur County. These ground squirrels emerge in early March, breed, rear their young, become exceedingly fat and go into their hibernacula by early August. Photo by ©John Rakestraw

The Piute ground squirrel is the other of the two small gray ground squirrels without stripes or spots. In Oregon, it occurs south of Sheepshead and Cedar mountains in Malheur County. It is a species of the High Desert and commonly occurs in habitats in which the dominant shrub is big sagebrush, saltbush, or greasewood. It is commonly associated with rocky outcrops, levees, railroad embankments, ditchbanks, and sand dunes. Some occur in fencerows and edges of alfalfa and small-grain fields. These ground squirrels are usually active for three to five months each year. They emerge from their hibernacula in February…

The Washington ground squirrel is the smaller of the two short-tailed, spotted ground squirrels in Oregon. The dorsum has squarish grayish-white spots on a background of pale smoky-gray with a pinkish wash to brownish gray. This squirrel is endemic to the Deschutes-Columbia Plateau Province east and south of the Columbia River and east of the John Day River. A colonial species, it emerges from dormancy in January to early March, males before females. At the approach of a potential threat, the Washington ground squirrel produces a soft, lisping whistle. Other members of the colony respond by standing upright, repeating the…

The Eastern gray squirrel is the smallest member of the genus in Oregon. This squirrel was introduced into Oregon and can now be found in Salem, Portland, Milwaukie, and Vale. All populations in Oregon have been found in urban areas. This squirrel is active throughout the year, activity restricted to daylight hours. Photo from Washington Fish and Wildlife

The Western gray squirrel is the largest tree squirrel in the state. It occurs from central Wasco, Jefferson, Deschutes, and Klamath counties west, except for unforested portions of the Willamette Valley, to central Washington, Benton, Lane, Douglas, Coos, and Curry counties. It is commonly associated with mixed forest communities. These squirrels are wary and secretive, but curious; they examine new objects placed in their environment but, once captured, they often avoid live traps. Western gray squirrels are an Oregon Conservation Strategy Species in the Willamette Valley ecoregion. Photo from ODFW

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…

The Douglas' squirrel is one of the smaller tree squirrels in Oregon. The color and markings of this squirrel differ individually, geographically and seasonally, appearing a dusky olive to brownish gray with an indistinct band of reddish brown with a blackish band along the flanks. In Oregon, it occurs in coniferous forests from the Pacific coast to as far east as western Baker County. Douglas' squirrels are active during the daylight hours year-round, although they may remain in their nests or tree dens for a day or two during inclement weather. Photo by Kathy Munsel, ODFW

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.

The Northern flying squirrel is the smallest arboreal squirrel in Oregon. It is typically squirrel-like except that the fore- and hind legs are connected by a furred patagium that extends from the ankle to the wrist. It is lead colored with buffy brown to brown tips. It occurs in forested areas west of the Cascade Range and eastward to near Lakeview, Lake County and Paulina Lake, Deschutes County. The species also occurs in the Blue, Ochoco, and Wallowa mountains. Northern flying squirrels are mostly nocturnal although individuals may be observed abroad during light hours on rare occasions. They are usually…

Oregon has five species of pocket gophers that are specially equipped for digging and tunneling. They have large-clawed front paws with small eyes and ears. Sensitive whiskers help them navigate underground.
