Oregon has two sea lion species and three seals. The Steller sea lion, Northern elephant seal and Pacific harbor seal are Oregon Conservation Strategy Species.

Features: Sacramento perch are blackish above with about seven vertical dark bars that are irregular in form and position. They are not a true perch, but a sunfish. It is the only member of the sunfish family native to the west coast and, in Oregon, is found only in the Klamath Basin. Sacramento perch are distinguished from the other sunfish in Oregon by having 12 or 13 dorsal fin spines whereas all the others have 10 or fewer. Maximum size in Oregon is about 12-inches in length and a weight of about 3/4 pound, although in California they have been…

Oregon has two species of pelicans, American white and the Brown pelican, and three species of cormorants. All are fish-eating water birds with four toes joined by webbing. Depending on the species, pelicans and cormorants inhabit the Oregon coast, rivers or interior waterbodies.

The enigmatic Solitary sandpiper may be one of the least understood of Oregon's regularly occurring shorebirds. As its name implies, the species is most often found singly, and it rarely occurs in groups of more than two individuals. The Solitary sandpiper frequents habitats not often utilized by other migrant shorebirds, such as smaller and often partly wooded patches of water, and high-altitude bogs and wet meadows. It is an uncommon to rare migrant in fresh water or brackish habitats throughout Oregon; rarest along outer coast and in alkali habitats. Spring adults more common in the western interior valleys; fall juveniles…

The Bald eagle is one of eight species of sea-eagle worldwide, and the only sea-eagle found throughout North America. It is one of the most studied North American birds. Large size, wingspan of six-and-a-half to eight feet, and the contrast of white head and tail, and yellow eyes, beak, and leg, to dark brown body and wings make the adult Bald eagle one of our most distinctive raptors. Six age-related plumages have been recognized; adult plumage is acquired at four-and-a-half to five years of age. Sexes have similar plumages, but females are larger than males, and the sex of individuals…

Black bears are the largest extant carnivores in Oregon. They are, however, smaller than grizzly bears, and they lack the grizzly's distinctive shoulder hump. A black bear is heavily built with stout legs and large feet. The eyes and ears are relatively small and the tail is extremely short. The claws are recurved but relatively short with those on the forefeet equal to or only slightly longer than those on the hind feet. The characteristic humped shoulders and dished face of the grizzly bear are absent. During spring-autumn seasons, black bears tend to be more active during daylight and crepuscular…

Lizards are more like ancient reptiles than either snakes or turtles. There are more than 2,500 species of lizards known in the world and they range from legless, snake-like varieties to the better known, four-legged type with five toes on each foot and scaly skin. Most lizards lay eggs but some give birth to live young. Most eat insects and small animals; some eat plants. Many lizards are very fast and most can swim. Some can even "swim" through sand, just below the surface. Lizards don't like to be caught and several species will take some pretty drastic steps to…

Features: Gaper clams have large "neck" housing the two siphons that protrude above the substrate surface when feeding. Protective leathery plates are found just below the siphon tips and feel rough to the touch. Gapers are unable to retract‌ their neck entirely into the shell, producing a "gape" in the shell. It is common for algae to grow on their necks and gaper pea crabs to dwell inside the shell with the gaper clam.‌ Habitat: Gapers can be found in high salinity sandy and/or muddy areas in most of Oregon's larger estuaries. Tillamook, Netarts, Yaquina, and Coos‌ are favorite bays…

Townsend's mole is the largest talpid in Oregon. In Oregon, it is restricted to the interior valleys and coastal regions west of the foothills of the Cascade Range. It occupies pastures, prairies, and shrub habitats in lowlands and river flood plains. The highest densities were recorded in pasture areas in Tillamook County. Photo by J. Maughn, Flickr

The Ord's kangaroo rat is a medium-sized kangaroo rat with awl-shaped lower incisors. It is the lightest-colored kangaroo rat in Oregon; overall the dorsum is a rich buff with gray overtones. The venter, upper lip, feet and side of the tail are white; there is a white spot above each eye and behind each ear; and a white stripe crosses each thigh. The moustache, eyelids, and ears are blackish. In Oregon, it occurs east of a line connecting The Dalles, Hood River County; Sisters, Deschutes County; and Lakeview, Lake County except in the Ochoco, Blue, and Wallowa mountains. Although occasionally…

The Merriam's shrew is the smallest shrew in Oregon. This brownish shrew has a short, truncated skull and is medium dark-brown on the dorsum and pinkish white on the venter; the tail is sharply bicolored in the same tones as the body with dark and light portions about equal. In Oregon, it has been found in Grant, Harney, Lake, and Wasco counties. It occupies drier habitats and is reported to be associated with sagebrush-bunchgrass habitats.

The Southern red-backed vole is among the smaller voles in Oregon. The pelage is silvery on the venter and grayish with ocherous on the sides, and with a rusty or reddish stripe on the dorsum; the tail is dark brown or black above and whitish or grayish below. In Oregon it occurs in the Ochoco, Blue, and Wallowa Mountains southwestward to central Crook County and northern Harney County. Photo by D. Gordon Robertson, Wikipedia

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…

Greater sage-grouse are best known for their elaborate courtship displays that occur on traditional strutting grounds, known as leks, where males gather each spring. At all seasons, both sexes are readily identified by large size and chicken-like build. Adults are mottled dark gray, black and buff, with black bellies and pointed tails. Males have specializations used in display. Their tail feathers are long and pointed with white spots. They have yellow combs over each eye and a chest sac with two bare, yellow patches of skin which are inflated during display. The display lasts only a few seconds and is…

The Rufous hummingbird is the most common and widespread of Oregon hummingbirds. This rusty-red and fearless nectar feeder is a popular yard bird, inspiring even the most modest of nature lovers to set up a feeder. It is a common transient and breeder throughout most of western Oregon, especially in forested regions. Hear the call of the Rufous hummingbird Photo by Charlotte Ganskopp
