Features: Their eyed-side is greenish-brown to dark brown or black with lighter blotches. Their blind side is white to milky-white. They have a large, stout but flat body, shaped like an elongated diamond . Pacific halibut have been known to reach 500 pounds, but on average are 40 pounds. Habitat: Halibut are a large flatfish and so they spend much time near the bottom of the ocean looking above for food. They prefer chilly water and are primarily found in the Gulf of Alaska. Technique: Boat anglers use heavy rods to fish on or near gravel bottoms in water 150-500…

This stocky, medium-sized shorebird is a denizen of Oregon's rocky shoreline, foraging as close to the crashing waves as possible, hence its name. It uses the rocky intertidal zone which includes jetties, offshore rocks and rocky shorelines, sea stacks, and tidal pools and is occasionally found on sandy beaches interspersed with groups of rocks, and on mudflats near the mouth of the Coquille River. It sometimes uses freshwater outfalls for bathing. Birds wintering in Oregon have the upperparts, head, neck, and breast slate gray with a whitish eye-ring. Indistinct supercilium and chin are white, wheres the belly and abdomen are…

These small, fast flying seabirds are unique among alcids in North America in their use of coastal coniferous forests, primarily old-growth trees, as nesting habitat. Their solitary nests are usually concealed within the forest canopy, and breeding birds are cryptic and primarily crepuscular at nest sites. Because of their secretive behavior and elusive nests, Marbled murrelets were considered the "enigma of the Pacific" and were one of the last ornithological mysteries in North America, as the first nest was not discovered until 1974. Distribution at inland nesting sites is fragmented, as birds occur only in areas where suitable habitat remains…

The European starling is considered an invasive species in Oregon. It was introduced from Europe. They most closely resemble blackbirds, with which they often flock in fall and winter. While both have iridescent plumage, starlings can be told from blackbirds by their two-toned wing pattern - dark upperwing, pale underwing - and during the breeding season by the bright yellow bill. Starlings adapt readily and quickly to human habitation and are highly efficient and successful breeders. However, the abundance of the bird, the rapidity with which it has spread across North America, and its propensity to cause damage to crops…

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…

The California sea lion is the mid-sized Oregon otriid. The body is slender and tapering, the flippers are relatively small, and the rear flippers can be rotated beneath the body for moving on land. The short, course pelage lacks dense underfur; when dry, it usually is chocolate brown, but individuals with light-tan pelage are known to occur. The pelage appears black when wet. In older males, the pate is tan. The occurrence of the California sea lion along the Oregon coast is seasonal. The primary areas where it comes ashore are Cascade Head, Tillamook County; Cape Argo, Coos County; and…

Features: The name “cutthroat” is derived from the two red slash marks or streaks on the underside of the lower jaw. Lahontans don't develop the intense crimson or gold coloration that other subspecies do, but the males can develop some red on their sides. Spots on the head can help distinguish this subspecies from other inland cutthroat subspecies. Habitat: This variety has adapted to the dry, highly alkaline waters and was once widespread throughout the Lahontan Basin of California, Nevada and southeast Oregon. Today, native populations can be found in the Whitehorse and Willow creek basins in the far southeastern…

The song of the Yellow-headed blackbird, if it can be called a song as it lacks any musical quality, is a familiar sound in the marshes particularly of central and southeastern Oregon. The male, with its yellow head, neck, and breast, black body and wings, and white wig patches, is unmistakable. The female is more subtle with its dusky or sooty brown body plumage and yellow cheeks, chin, throat and chest, but is also distinctive. It is an abundant spring and summer resident in marshes of large alkaline lakes and wetlands in southeast Oregon, most notably the Klamath, Summer, Malheur…

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…

This sturdy-looking bird has a large head, short tail, and massive conical bill adapted for seed eating. The male plumage features bold patches of lemon yellow shading into olive, then brown and black, with white secondaries creating a flashy wing-patch easily seen in flight. The male's bill is chalky white in winter, but changes in early spring to a pale green that matches the new growth at the tips of spruce boughs, where they often nest. Many encounters with this species are of individuals heard flying high overhead, leaving the observer with little else to note. The Evening grosbeak is…

Features: Bullheads present in Oregon are distinguished from channel catfish by their square or rounded tails and lack of spotting. They seldom exceed 18 inches in length and a weight of 2 pounds. Yellow bullheads are a more uniform yellow color with white or cream chin barbels and a rounded tail. Habitat: Bullheads are found on the bottom in the shallows of mud-bottomed ponds, lakes, reservoirs and backwaters of rivers. The yellow bullhead is found mainly in the Willamette basin. Technique: Bullheads can be caught any month of the year, but fishing is best from the first warm days of…
