The red tree vole is a medium-sized vole. It is uniquely colored among North American voles: bright orangish-red to cinnamon on the dorsum, silvery gray (often with some light orangish hairs) on the venter, and a tail pale orangish on the venter grading to black on the dorsum. This vole is endemic to western Oregon. It occurs at moderate elevations on the west slope of the Cascade Range southward as far as the Douglas-Jackson county line and in the Coast Range to the Oregon-California border. It is largely arboreal and builds nests on suitable foundations (commonly nests of birds or
The gray-tailed vole is a medium-sized vole with yellowish-brown or yellowish-gray dorsal pelage and a short tail, blackish or brownish above and light gray below. It is endemic to the Willamette Valley and occurs from near Scapoose and Gresham south through the Willamette Valley to near Eugene. It is associated largely with agricultural lands, particularly small grains, grasses grown for seed, permanent pastures and hay fields, and waste places vegetated with grasses. These voles occasionally become so abundant that control measures are necessary.
The long-tailed vole usually is considered to be a medium-sized vole, although the size of an exceptionally large male may rival that of the largest Townsend's vole. The color of the dorsal pelage ranges from dull grayish through brownish gray to dark sepia brow. Those west of the Cascade Range have the darkest and richest-colored pelages. The sides are lighter and more grayish and the venter is grayish white to dull buff. The eyes and ears are large. In Oregon, the long-tailed vole occurs in 30 of the 36 counties. It is absent from the Willamette Valley and other interior
Features: Rocky Mountain bighorn sheep are the largest-bodied bighorn in North America and one of two subspecies of wild sheep in Oregon. Bighorn sheep were extirpated from the state in the 1800s so current populations are the result of a reintroduction effort by ODFW and sportsman groups. Habitat: Oregon’s estimated 800 Rocky Mountain bighorn sheep are found in the northeast corner of the state, in canyons of the Snake River and its tributaries and in alpine areas of the Wallowa Mountains. Techniques: Bighorn sheep are one of the rarest game species hunted in Oregon today, with about 100 tags available
The montane vole is a medium-sized vole. The pelage is ashy gray mixed with brown and black on the dorsum shading to light gray or whitish on the venter. The feet are lead colored and the tail is bi-colored black or dark gray above and light gray to whitish below. Splotches of different shades of yellow on the nose, venter, and dorsal surfaces of the feet and tail occur on some adult Montane voles. This vole is distributed throughout most montane and intermontane areas of the west occurring throughout that portion of Oregon east of the crest of the Cascade
The creeping vole is the smallest vole in Oregon. It has an exceedingly short tail and tiny eyes. The short, dense fur on the dorsum ranges from sooty gray to dark brown or black, with scattered yellowish hairs. Hair on the venter is dusky washed with buff or white; the tail is blackish, slightly darker above that below; and the fur on the ears is black. In Oregon, it ranges from Brooks Meadows and Crater Lake west to the Pacific Ocean. The species has been seen at some localities in the Willamette Valley. However, hiatuses in the distribution occur in
Other than the muskrat, the water vole is the largest arvicoline in Oregon. It occurs in the Cascade Range from Mt. Hoot to Mt. Mazama and in the Wallowa and Blue mountains east and north of a line connecting Langdon Lake, Umatilla County; the North Fork Malheur River, Grant County and Cornucopia, Baker County. It is considered an inhabitant of alpine and subalpine streamsides. The water vole is active throughout the diel cycle; however, activity is least from dawn to midday, rises during the afternoon, and peaks at night, probably after midnight. It is a good swimmer and can swim
The sagebrush vole is among the smaller voles in the state. The tail does not exceed the length of the hind feet. The long, soft, and dense dorsal pelage is grayish tan; the bases of the hairs are lead colored and the tips are black. The ventral pelage is pale buff, the feet light gray, and the tail slightly bicolored. In Oregon, it occurs mostly east of a line connecting The Dalles, Bend, and Klamath Falls, except it is absent from the Columbia Basin and most of the Blue and Wallowa mountains. Clustering of burrows tends to indicate that the
The common muskrat is the largest arvicoline rodent on Oregon. The body is heavy and rounded, and except for the tail and feet, heavily furred. The eyes are beady; the ears are rounded and almost covered with fur; the tail is flattened laterally, scaly, keeled, and naked except for a few hairs on the keel. The forefeet are relatively small, but the hind feet are large and partly webbed. The pelage consists of an exceedingly dense underfur usually overlain by glossy dark-brown guard hairs; the underfur is waterproof. Reddish, blackish, silvery, and white individuals have been recorded. In Oregon, muskrats
The common porcupine is a large, short-legged rodent with up to 30,000 bare-tipped quills (modified hairs) covering the upper parts of the body and the dorsal and lateral surfaces of the tail. The quills are scattered among much longer, course guard hairs; the underfur is woolly. The quills are arranged in rows across the body, the longest quills are on the rump, the shortest on the face. Quills used in defense are replaced commencing about 10-42 days after loss. The overall color of the porcupine is dark brown or blackish. The front feet have four toes, the rear feet five
The red fox has a beautiful orange-red coat, black feet, and black-tipped ears. The belly is usually white or light grey, the muzzle is narrow and pointed, and the ears are pointed. It is an opportunistic carnivore, eating what is available including small mammals, birds and their eggs, reptiles, amphibians, fruit and some insects. The red fox is territorial and mates for life Red foxes occur throughout much of Oregon.
The ringtail is shaped somewhat like a marten with an elongated body and tail of approximately equal length. The ringtail is named for its tail which has has eight dark bands alternating with seven buffy bands. The dorsum is buff overlain with blackish or dark-brownish guard hairs; the venter is whitish or light buff. The face mask is whitish, but the eyes are fringed with a narrow band of black. The toes are equipped with semi-retractile claws, and except for the pads, furred on the ventral surface. The ears are long and set wide apart on a nearly horizontal plane
Features: Like all cutthroat trout, this species boasts bright red streaks on either side of its “throat.” You can tell it’s a westslope cutthroat by its spot pattern – the majority of the black spots are found on the back end of the fish with rather few ahead of the dorsal fin. Habitat: While westslope cutthroat trout was once the most widely distributed cutthroat in North America, its home in Oregon has always been limited to the John Day Basin. During the cooler months of summer you can find them in places like Strawberry Creek and upper Canyon Creek. As
Features: While in the ocean, Chinook salmon often have a purple hue to their backs with silvery sides and bellies, large oblong black spots on the back, and round black spots on both lobes of the tail (note that tail spotting may be obscured in ocean fish by “silver” in the tail). Upon returning to freshwater to spawn, Chinook darken in color and develop red on their bellies and fins. A key identifier is the black gum line on the lower jaw with dark colors both inside and outside of the gum line. Spawning generally occurs from August to early
Features: When in the ocean coho salmon can look very similar to Chinook salmon. However, coho will have a white gum line on the lower jaw with darker color both inside and outside of the gum line, and will only have spots on the upper lobe of their tails. When coho return to freshwater they become red on their sides and dark greenish on their backs, heads, and fins. Coho adults may reach 25 pounds or more, but rarely exceed 15 pounds. Habitat: Small, relatively low-gradient tributary streams with pea to orange-sized gravel for spawning and juvenile rearing. Coho may
Features: Kokanee are silvery in color until they are ready to spawn, at which time they become reddish. They do not grow as large as sockeye- their ocean traversing siblings. They can vary significantly in size depending on how densely populated the waterbody is. Since they are filter feeders, their populations can quickly expand and contract with the availability of food. Habitat: Kokanee can be found at all depths of cold, clear lakes and reservoirs in several parts of the state. They will change which depth they are at depending on water temperature. Technique: They are a challenging fish to
Features: These fish are silver when young, but darken and develop black spots on their tails and backs as they age. In fresh water, the males are red on their sides and develop a hump on their backs earning this species the common name humpback salmon. Females in fresh water are green on the sides with dark bars. Pink salmon are an average of 20- to 25-inches long and rarely weigh over 5 pounds. Habitat: Pink salmon spawn on odd numbered years and do so very close to saltwater, never going very far upriver. In fact, some pink salmon will
Features: These fish are light silvery-white, dark on top, and have up to 8 dark, broken stripes running along the sides of their bodies. They are typically less than 10 lbs but can grow to 22 lbs. They have two dorsal fins, the front one with eight or nine spines and the rear one with one spine and 13 or 14 soft rays. Habitat: Hybrid bass were originally stocked in Tenmile Lakes on the south coast and in Ana Reservoir in Lake County. They have since been introduced into Thompson Reservoir, also in Lake County. The only established population is
Features: Smallmouth bass are golden green to bronze with dark vertical bars and blotches on the side. The upper jaw does not extend beyond the eye. In some locations, it has a red eye. Somewhat smaller than the largemouth, smallmouth bass in Oregon may reach 23-inches and exceed 7 pounds. Habitat: Smallmouth bass are adapted to flowing waters and do well in warm streams with deep holes and rocky ledges. They also prefer lakes and reservoirs with rocky shorelines and limited vegetation. Adult smallmouth feed mostly on fish and crayfish. Technique: Much of what was written about largemouth bass also
Features: They are dark olive on the tops of their bodies, silver on the sides, and white underneath, with 6-9 black stripes running horizontally from behind their heads to their tails. Habitat: Striped bass spend most of their time in fresh water, with occasional and unpredictable trips to the sea. Technique: In the spring and fall stripers are likely to be closer to the surface. During this time bait, such as dead minnows or night crawlers, will entice the fish to bite. During summer, the bass go deeper to escape the heat. This is the time to use flashy bait.
