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 American bullfrog is a non-native invasive frog that survives and reproduces very successfully in Oregon. Bullfrogs aggressively compete for food and living space with our native frogs. They eat many types of native wildlife including other frogs, young pond turtles, and ducklings. Bullfrogs can lay almost 10 times more eggs than native frogs and can quickly out number them.

The goal of the Oregon Hatchery Research Center (OHRC) is to answer scientific questions related to fish recovery and hatchery programs. Information gained at the Research Center will help answer questions vital to the success of the Oregon Plan for Salmon and Watersheds and implementation of the Native Fish Conservation Policy. The Oregon Hatchery Research Center is a cooperative research project between the Oregon Department of Fish and Wildlife and the Oregon State University Department of Fisheries and Wildlife.
These elegant shorebirds are found as often in dry or damp upland areas as they are on mudflats or beaches. The plain brown immature birds of autumn become spangled with black and gold as breeding approaches. It is an occasional to uncommon migrant in western Oregon (mainly coastal) and locally rare, irregular migrant in eastern Oregon, with most reports at Malheur National Wildlife Refuge, in the Klamath Basin (summer) and in Umatilla County.

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…
The kit fox is the smallest canid that occurs in Oregon. It has the typical canid conformation: the body is slim, the legs are long and thin, and the ears are large and erect. The tail is about 40 percent of the total length and is tipped with black, but has no dark mane on the dorsal surface. The feet and legs are whitish interiorly, light rusty-brown posteriorly. The dorsum is grizzled brownish-gray medially blending to grizzled gray then to light buff laterally and finally to white on the chest and venter. The head and posterior surface of the ears…
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…
The bighorn sheep is a medium-sized, largely brownish bovid with a white rump patch, muzzle, venter, and rear portion of the legs. The tail is blackish brown on the exposed surface. The hooves are equipped with a rubberlike pad that facilitates negotiating rocky terrain. The ears are relatively small and somewhat pointed. Both sexes are equipped with horns; those of males are massive and spiral outward, whereas those of females are relatively thin, recurved, and mostly directed upward and posteriorly. Horn growth reflects nutritional status. Bighorn sheep are capable of moving with speed and agility through the precipitous terrain in…
The McKenzie River originates in the Cascade Range and empties into the Willamette River near Eugene, which then flows northward into the Columbia River. McKenzie Hatchery was first constructed in 1938 and rebuilt in 1975. Today, 30 rearing ponds, a visitor's center, spawning room, egg incubation facility, office, feed storage, shop area, fish ladder and picnic area are the main components of the facility layout. McKenzie Hatchery is temporarily closed to comply with Oregon Department of Environmental Quality permit conditions. Visitors should be aware that no fish are present in the facilities' production raceways and show ponds. Fish have been…
Round Butte Hatchery was constructed in 1972 to mitigate for the fishery losses caused by Pelton/Round Butte (PRB) Hydroelectric Complex. Round Butte and its satellite, Pelton Ladder, are used for adult collection, egg incubation and rearing of spring Chinook, summer steelhead, and sockeye salmon.
Trask River Hatchery was constructed in 1916 to replace an earlier hatchery that was located three miles upstream from the present site. Many improvements have been made to the hatchery since original construction including a new alarm system, early rearing building, and a 40’ x 60’ pole building. Trask Pond was constructed in 1970 and Tuffy Creek was constructed in 1988. The hatchery is used for adult collection, incubation, and rearing of fall and spring Chinook, coho, wild winter steelhead and hatchery winter steelhead.
Oregon's owls are mostly nocturnal, hunting for insects, fish, frogs, birds, mice and other small mammals in the night. Their hoots, screeches and calls can be heard after dark or early in the morning. Owls don't build nests, but instead use tree cavities, nests created by other species, naturally occurring structures or human-made nest platforms. The Western burrowing owl nests underground in abandoned dens dug by squirrels, prairie dogs and badgers. Learn more about Oregon's owls.
The Townsend's pocket gopher is a large pocket gopher. The pelage is dark buffy-gray to sooty gray on the dorsum and a rich buff on the venter; the face, nose and auricular patch are black; the feet are dirty gray; and the chin is white. This gopher occurs along the Malheur and Owyhee river valleys in Malheur County and in southern Harney County. Townsend's pocket gophers have been found in alkaline soils along the south shore of Harney Lake and in deep fertile soils near Sod House School near the headquarters of the Malheur National Wildlife Refuge and in Stergen…
This is a bird of riparian thickets, farmlands, and towns. Since 1980, it has been observed almost annually in Harney County, usually in numbers less than five. A pair successfully fledged young near the Malheur National Wildlife Refuge headquarters in 1994. Most Harney County records occur from early April to late October. Away from Harney county individuals have also been seen in the various eastern and southeastern counties of Oregon. Hear the song of the Great-tailed grackle Photo by Kathy Munsel, ODFW
The pelage of this mouse is grayish or brownish dorsally, the venter hairs are white with lead-colored bases, and the tail is light colored. In Oregon, it occurs within the area circumscribed by a line connecting Denio Nevada; Fort Rock, Lake County; Powell Butte, Crook County; Malheur National Wildlife headquarters, Harney County; and Burns Junction, Malheur County. On a daily basis, activity begins with an intense burst during the first light to hours after sunset, and declines to almost nil six hours after sunset, then, especially in summer, increases again before sunrise. The Dark Kangaroo Mouse constructs elaborate nests with…
The gray fox is among the smaller canids in Oregon. The basic color of the gray fox is grizzled gray, but the stiff middorsal hairs have long black tips that extend onto the tail as a black mane. Guard hairs are banded white, gray, and black. The throat, venter, and inside of the legs are white; a cinnamon-rufous border to the white throat extends on the flanks and underside of the tail A blackish patch on the side of the face extends onto the lower jaw and a grayish black "exclamation point" extends upward from the interior margin of each…
Western Oregon observers enjoy these large, elegant plovers almost year-round, and as a consequence they are one of the most familiar larger shorebirds. Almost all migrants and winterers visiting Oregon inhabit mudflats and open wet dirt fields. A few can be found on sand beaches and even occasionally on rocks, but the great majority are found feeding and resting on open mud. In Oregon, it is a fairly common to common transient in western interior valleys. East of the Cascades, the Black-bellied plover is an uncommon transient in the Klamath Basin and at Malheur National Wildlife Refuge. In winter it…
