Although common within its range, this handsome sparrow can easily be overlooked. The gray head, black malar stripe, white eyebrow, and prominent black spot set in the middle of a white breast identify the bird. It is widespread throughout the extensive shrub-steppe of central and eastern Oregon. The principal breeding range of Sagebursh sparrow is southeast and central Oregon. It is found throughout the arid expanses of the Great Basin and usually associated with big sage. Although considered by some authors to be a sagebrush obligate, Sagebrush sparrows have been found in other plant communities exclusive of sagebrush. Hear the

In Oregon, the opossum is considered an invasive species. The Virginia opossum is a cat-sized mammal with a pointed nose, unfurred, black, leathery ears with white edges; beady eyes; a hind foot with an opposable hallux (big toe); and a naked scaly tail. It was introduced in Oregon between 1910 and 1921. Populations were established in northwestern Oregon apparently from releases of animals brought to the state as pets or novelties. Small streams, forest communities, and agricultural lands planted to a variety of crops are typical of many habitats occupied by Virginia opossums in Oregon. They are active nocturnally and

The rock scallop ( Crassadoma gigantea) lives in the swift current shallows of Oregon's nearshore rocky reefs. Due to the coloration at its hinge, it is also known as the purple hinged scallop. These highly specialized scallops cement themselves to rocks, primarily at depths from 10 to 150 feet. They feed on microscopic plankton they filter from the water and reproduce via broadcast spawning. In order for spawning to be successful, they need to be close to one another. For this reason, it is best to harvest solitary rock scallops and minimize harvest pressure on dense aggregations which are more

A slender, orange bill, pearl gray upperparts, and fringed black crest adjoining a white face and neck indeed render this graceful hunter from the south elegant. The foreheads of adults turn white in post-breeding plumage, their usual state in Oregon. These terns frequent quiet waters or lagoons when diving for fish, but also dive in calm ocean waters. They roost with flocks of gulls and other terns on coastal spits, estuarine sandbars, and on mudflats close to bay mouths. Virtually all records of the Elegant tern in Oregon are coastal or within half a mile of shore. None have been

A big, well-mannered bird of friendly, even playful disposition, with an abundant curiosity as to human presence and activities within the realm of open ocean over which he presides. Long-winged, to seven feet, and dark sooty-brown; adults have a white rump and feathering, which juveniles lack, around the base of a large bill. Every sighting of these gentle giants gliding up to the boat evokes delight. The black-footed albatross is a regular visitant spring through fall offshore, but is irregular in winter. They glean squid, fish and fish eggs from the ocean surface and also eat galley scraps. Hear the

The Golden eagle is the largest soaring raptor inhabiting open country and mountainous terrain in eastern Oregon. A powerful and skillful hunter, the Golden eagle has become the National icon of the American West. A very large, dark raptor, the nape golden in all plumages, the females are slightly larger. Juvenile birds show white patches at the base of the primaries and a white tail with a broad dark terminal band. They are common residents in all Oregon counties east of the Cascade range. The Golden eagle inhabits shrub-steppe, grassland, juniper, and open ponderosa pine and mixed conifer/deciduous habitats. It

Known as "bluebill" to most hunters, this species is one of the most abundant and widespread of North American ducks. The lesser scaup is similar to the greater scaup in appearance and habits, but is smaller and lacks the white on the primaries. In the field, however, the black-and-white drakes and brown hens are very similar to greater scaups. The common vocalization is the purr call of the female; drakes are usually silent, but utter a low single-note whistle in courtship. In general, the lesser scaup is more apt to be found in interior or freshwater habitats while the greater

Rhinoceros auklet are one of the rarer breeding alcids in Oregon. Adults are easily recognized during the breeding season by the vertical "horn" at the base of the upper mandible. Birds in breeding plumage have brownish gray backs, a gray-brown chest, and a dirty white belly. Two distinct plumes are present on the head, one above and one below the eye. The bill is orange. In non-breeding plumage the horn is greatly reduced, the plumes absent or reduced, and the bill duller. It nests in small numbers in Oregon with Goat and Hunter Islands having the largest concentrations of breeding

California quail are the most widely distributed upland game birds in Oregon. Most easily recognized by the comma-shaped, black, plume, or "topknot," which bends forward and is larger on the male. It has been a resident statewide since the early 1900s, except for most forests of the north Coast Range and west Cascades; it is generally absent along the coast north of Coos Bay. California quail is also absent from high-elevation areas of the east Cascade range. They are common residents in rural and even some suburban areas, particularly in eastern Oregon where many coveys gather at feeding stations during

The Piute ground squirrel is the other of the two small gray ground squirrels without stripes or spots. In Oregon, it occurs south of Sheepshead and Cedar mountains in Malheur County. It is a species of the High Desert and commonly occurs in habitats in which the dominant shrub is big sagebrush, saltbush, or greasewood. It is commonly associated with rocky outcrops, levees, railroad embankments, ditchbanks, and sand dunes. Some occur in fencerows and edges of alfalfa and small-grain fields. These ground squirrels are usually active for three to five months each year. They emerge from their hibernacula in February

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
