Of Oregon's breeding seabirds, Leach's storm-petrel is the smallest, most pelagic, and flies the farthest offshore of any of Oregon's breeding seabirds to feed. It spends the non-breeding season in the subtropical and equatorial Pacific. It is the second most abundant breeding seabird in Oregon, and is rarely seen from land or close to shore. It comes to its breeding islands, where it nests in burrows, only under the cover of darkness. Its plumage is black and Oregon populations have a distinct white rump. Leach's storm-petrels are long lived birds characterized by long-term pair bonds and may breed yearly for…

The Turkey vulture, known locally as a "buzzard," is a common sight spring through fall throughout the state, except in the highest mountains and featureless desert expanses in summer where they are uncommon. Seeing Turkey vultures returning is a welcome sign of spring. Turkey vultures are large-winged soaring birds with overall dark plumage except for a silvery sheen on the undersides of the flight feathers. Adults have small, featherless, red heads, while juveniles have gray heads. The Turkey vulture is a common to abundant transient throughout the state and an uncommon to common summer resident except in high mountains. It…

Cryptically colored, usually solitary and somewhat secretive, the Wilson snipe is often flushed before being seen, sometimes exploding from practically underfoot and rocketing off in a corkscrew flight. This plump-bodied, long-billed bird of open marshland is primarily crepuscular, peaking in feeding activity at dusk and dawn, and often sleeping during the day. In breeding season they become more flamboyant, appearing atop fence posts and displaying their unique winnowing flights from high in the air, their outer tail feathers vibrating with an eerie whistling sound. They are uncommon and local west of the Cascades in the summer and uncommon and local…

A white form on the distant water may be the sides and breast of an adult male, whose deep green head and dark back are less visable when far away. The pearl gray bodies and white breasts of females, subadults, and eclipse males are starkly delineated from their full-crested chestnut heads. Long, slender, saw-tooth bills are held horizontally during surface swimming and grip squirming prey after an underwater chase. From coastal bays to the high Cascades, in all corners of Oregon and far beyond, common mergansers ply the rivers and peer into still waters in their efficient pursuit of fish…

Features: Coastal cutthroat trout are typically are blue/green on top, red along the lateral line, and white on the belly. They are lightly or heavily spotted and adults have a red slash mark on the throat. Habitat: The most common variety of trout in Oregon is the coastal cutthroat, found in the streams and beaver ponds in coastal drainages. They also are stocked in high mountain hike-in lakes where the water stays cool throughout the summer. Techniques: Cutthroats that are year-round residents of small streams may not get any bigger than 8- or 9-inches, but can reward the angler with…

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 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…

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 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…
