Ruffed grouse are named for a series of black iridescent feathers on the sides of the neck called the ruff, which is erected by males to form an ring around the neck during courtship displays. This forest-dwelling species, favored by upland game-bird hunters, is well known for the drumming of the males during courtship displays in the spring. It is a common resident throughout most forested regions of the state. It occupies most forests at low to moderate elevations east of the Cascade crest, primarily the east slope of the Cascades from Ft. Klamath and upper Klamath Lake and Blue

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

The wild turkey is the largest game bird in North American with mature males weighing upwards of 20 pounds and standing 40 inches tall. These large terrestrial birds are generally dark brown to black in appearance but iridescent color in feathers ranging from gold and copper to green and black gives a metallic appearance, particularly in full sunlight. Males and about 10 percent of females sport a unique beard of keratinous filament that protrudes from the junction of the breast and neck. Beards grow continuously but rarely exceed 10 inches in length. Females are smaller and duller in appearance. Densities

Although quite common in the U.S., the Black-crowned night-heron's nocturnal and crepuscular feeding habits can make it difficult to locate. Its habitat consists of marshes, lakes, rivers, and other wetlands, where it feeds mostly on fish. It is a thick-billed, medium-sized, stocky heron with relatively short neck and legs. Adults have a black back and cap which contrast with the pale gray or whitish underparts. Immatures have brown backs with large pale spots and heavily streaked underparts. A distinctive choking squawk call is often heard at dusk. It is a fairly common summer resident east of the Cascades where it

Features: Redear sunfish are often confused with bluegill, but differ by having a red or orange border around the black ear flap and by lacking the spot on the dorsal fin and the vertical bars on the side. Habitat: In Oregon, redear sunfish are found only in a few ponds in the Willamette Valley and the central part of the state. In their native range, redear sunfish prefer warm, large lakes and reservoirs and bayous with vegetated shallow areas and clear water. They feed primarily on the bottom and seldom take surface insects. The diet consists mostly of zooplankton, insect

Gulls and terns can be seen year-round in Oregon, depending on the species. Gulls like open areas around water bodies and are frequently seen where human food is concentrated, such as dumps or restaurants. Terns are in the same family and usually are smaller and more slender.

Features: Pumpkinseeds may be identified by the orange or red spot on the ear flap and the orange cheeks with wavy blue or turquoise stripes. Color is exceedingly brilliant and somewhat variable; olive to brassy-green above, the back finely dusted with gold or emerald. Habitat: Pumpkinseeds are found in the same habitats and often in association with bluegills. Adults often congregate beneath old deadheads and trees that have fallen into the water. Food habits are also similar to bluegill. They consume large numbers of snails by browsing on the stalks of aquatic vegetation. Techniques: Pumpkinseed are found in many of

Features: Warmouth have more of a bass-shaped body and a larger mouth than the other sunfishes, other than the green sunfish. Warmouth are yellowish brown in color with three or four brownish bars radiating back from the eye over the gill cover. They can be distinguished from the green sunfish by the absence of turquoise mottling on the gill cover and the lack of a dark spot at the rear base of the dorsal fin. Habitat: In Oregon, warmouth are present in a few coastal lakes and widely distributed in the Columbia basin, but are not commonly caught by anglers

Features: Color varies, but walleye are generally dark olive-brown on top grading to almost white below. Walleye have two well-separated dorsal fins; the first fin has a large black spot at its rear base. The opaque eyes, giving the fish its common name, and canine teeth are other prominent features. Habitat: Walleye are found in the Columbia, Willamette and Snake rivers. In the Willamette River, the walleye fishery is generally limited to the section downstream from Willamette Falls at Oregon City, although a few have been documented as far upstream as Dexter Dam. Walleye prefer large, clean and cold or

The gopher snake occurs in a wide variety of habitats, from deserts and grasslands to woodlands and open forests. It frequents agricultural regions, especially where there is brushy cover such as fence rows. Diet varies according to size, with young eating insects, lizards, rodents, and birds and their eggs. Adults can take larger prey, occasionally as large as rabbits. Photo by Simon Wray, ODFW

Features: Largemouth bass are greenish on the back and sides with a white belly and usually a dark horizontal stripe along the side. They are distinguished from their close cousin, the smallmouth, by a large mouth with the upper jaw extending behind the eye. Largemouth bass in Oregon can exceed 25 inches in length and a weight of 12 pounds. Habitats: Their preferred habitats are shallow ponds and lakes, or the backwater sloughs of rivers where aquatic plants or submerged logs and brush provide abundant cover. Largemouth bass begin life feeding on zooplankton (tiny crustaceans), but soon switch to insects

California myotis is an acrobatic flyer. It is dark brown to blond with dark ears, and feeds on moths and flies. Early in the summer, a female joins a maternity or nursery colony where she gives birth to one offspring. In winter, these bats roost in mines, caves and buildings. The California myotis is an Oregon Conservation Strategy Species found throughout the state except for the Columbia Basin. Photo by ©Michael Durham

Features: The color of all trout varies with environment. In general, the rainbow is bluish-green on the back, silvery on the sides and belly, and has a white edge to the dorsal, anal, and pelvic fins. A generous sprinkling of black spots appear along the back, and on the dorsal, adipose and caudal fins. A pinkish band usually extends along the sides. Habitat: Rainbow trout are the most widely stocked and distributed trout in Oregon. They occur naturally in many rivers and streams, and each year ODFW stocks millions more in ponds, lakes and streams. Prime trout waters are clear

The song of this wren is often mistaken for the Song sparrow in the thickets and open woodlands where it resides. When in view, however, its long tail, thin bill, and white line above its eye are distinctive. Found in a variety of habitats, it readily takes advantage of cleared forest grown to large shrubs, especially blackberries. It is a permanent resident west of the Cascades, in Klamath and Warner basins, and along the upper Columbia River and tributaries. Hear the song of the Bewick's wren Photo by David Hoffman, Flickr
