A research study that began in 2012 confirmed Sierra Nevada red fox presence in the Oregon Cascades, specifically in the Mt. Jefferson, Mt. Washington, and Three Sisters Wilderness Areas. Confirmation was through genetic testing of hair and scat samples. Sierra Nevada red fox is a subspecies of Red fox that live in high elevations. They are slightly darker than Red fox and are highly specialized to montane (mountain) ecosystems. In the red color phase, the upper body is reddish-brown with white chin, cheeks, throat and belly. This fox ranges from silver to black in the black/silver color phase with silver
Swainson's hawks are medium-sized buteos, smaller than Red-tailed and Ferruginous hawks. Plumage beneath varies along a continuum from very pale to nearly black below. Lighter-plumaged birds have a distinct chest band. They have relatively long, pointed wings that contribute to superior flying skills. The dark flight feathers contrast with paler wing lining in all but the darkest birds. It breeds in the bunchgrass prairies east of the Cascades with the highest concentration in the foothills of the Blue and Wallowa mountains. It prefers open country and has little need for numerous trees since it forages extensively while in flight and
This largest of Oregon's hawks inhabits the most open country of the state's buteos, and watches over its home range on long, motionless wings for extended periods in search of prey. Ferruginous hawks are sensitive to human disturbance and tend to reside in remote areas. They occur in two color morphs, but dark-morph birds are rare in Oregon. Light-morph birds are white below with few markings except for the ruddy-colored leg feathers. The back and wing coverts are rust colored and the tips of the primaries and end of the tail tend toward dark smoky gray. It is an uncommon
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
In length, the Great gray owl is Oregon's largest owl, though it weighs less than the Great horned and Snowy owls. It is sooty gray to brownish above and lacks ear tufts. The prominent facial disc, outlined in black, contains a series of fine concentric rings that surround piercing yellow eyes. Despite its large size, both feet and bill are small. Sexes are similar. It is an uncommon to rare inhabitant of forests adjacent to openings above 3,000 feet in the Cascades, Blue, and Wallowa mountains. Most observations in the Cascades are from east of the crest, though they have
Adult clouded salamanders are generally brown with brassy patches on their backs and gray bellies. As salamanders age, the brassy color fades. The clouded salamander is one of the lungless salamander species; they breathe through their moist skin. Mature adults can grow to just over five inches in total length. Clouded salamanders prefer forest habitats or burned areas that provide large decaying logs or stumps. They are often found in Douglas fir trees where they can find burrows in the wood, or spaces just under the bark to hide. They may also hide deep in rock crevices during dry and
These large toads are well camouflaged in earth tones with dry bumpy skin that aids in protection from predators. Their color can be highly variable among individuals ranging from gray or reddish-brown to yellow or green. They have a light colored stripe that runs along the center of the back. Adult female toads are larger than males, growing to five inches in length. They live mainly on land in a range of habitats from forests to mountain meadows to desert flats. During the non-breeding season, they are nocturnal. They dig their own burrows in loose soil, use existing burrows or
Adult Oregon spotted frogs have moist bumpy skin that is reddish-brown on their topsides. On their heads, backs, sides and legs, they have black spots with light centers that darken with age. They also have red bellies and orange-red underlegs. Adult females grow to four inches in length and males to three inches. Oregon spotted frogs live in wet areas that provide abundant aquatic vegetation such as marshes, permanent ponds, lake edges and slow streams. When frightened, they hide in dense vegetation or under debris at the bottom of shallow wetlands. Adult frogs hibernate during the winter in freeze-free seeps
This small, boldly-patterned duck can be found in Oregon throughout the year, either around rocky headlands on the coast or inland on mountain streams. No other breeding duck in Oregon feeds almost exclusively on benthic invertebrates, often swimming underwater and upstream against swift current in search of prey. Though males are striking in appearance, these and the drab brown females can be difficult to see when at rest on a mid-stream rock or dodging behind rocks as they evade observers. Broods have been observed or nests located on tributaries in the river basins of the west Cascades. They are found
The chat's coming in the spring is like the arrival of a brass band. Male chats are loud, continuous singers, sometimes heard through the night. Chats inhabit lowland tangles and thickets along rivers and floodplains. It is the largest of North American warblers. In western Oregon, the chat is an uncommon to common summer resident of the interior Rogue Valley. It is a locally uncommon summer resident in the interior Umpqua Valley. In the Willamette Valley it is a locally rare to uncommon summer resident, and rare east to Oakridge. In eastern Oregon, the chat is a rare spring migrant
Bobolinks summer in Oregon's eastern grasslands and meadows, singing what has been described as a bubbling delirium of ecstatic music that flows from the throat of the bird like sparkling champagne. The yellow-brown female, juvenile or non-breeding male may at first appear to be a sparrow, but the breeding male has an astonishing and diagnostic backwards tuxedo pattern of buff on the nape and white rump and scapulars on an otherwise black body. The Bobolink is a regular, locally common breeder at the Malheur National Wildlife Refuge and a few scattered pairs occur in northeast Oregon. West of the Cascades
These large salamanders are marbled brown and tan in color when in their rare terrestrial (land-living) adult form. They are brown with yellowish-tan patches on These large salamanders have an aquatic adult stage that is brown with yellowish-tan patches and short gills. The rare terrestrial adult is marbled brown and tan. Larvae of Cope’s giant salamander are smaller with a more narrow head and shorter legs than the coastal giant salamander. Both terrestrial and aquatic adults can grow up to eight inches in total length. Most adult salamanders live in cold, fast-flowing, clear and permanent streams in coniferous forests. Adult
The Fisher is considerably larger than the marten and males are considerably larger than females. It is more stockily built than the weasels, but is similar in that the head is somewhat pointed, the body elongate, and the legs short. The pelage is long except on the face. The fur is dark brown grading to black on the rump and legs; the tail is black. Fishers once occurred throughout the coniferous and mixed forests of Oregon's Coast Range and Cascade Mountains. Currently, there is a native population in the Siskiyou Mountains and an introduced populations in the southern Cascades that
The Long-billed curlew is the largest North American shorebird. Its most striking morphological characteristic, the long decurved bill, is an adaptation for foraging on earthworms or burrow-dwelling organisms like shrimp and crab. Body plumage is a rich buff with a tinge of cinnamon or pink. Sexes have similar plumage, but females are larger with a longer bill. It can be distinguished from other curlews in flight by its bright cinnamon underwings. When observed on the ground, the Long-billed curlew's head lacks the strongly streaked pattern of other cerlews or Whimbrel. It is a locally common breeder in open grassland areas
The Olive-sided flycatcher is one of the most recognizable breeding birds of Oregon's conifer forests with its resounding, three-syllable whistle song quick, three beers. It is a relatively large, somewhat bulky, large headed, short-necked flycatcher that perches erect and motionless at the top of a tall tree or snag except when singing or darting out to capture flying insects. The overall olive-gray plumage is generally nondescript except for a whitish stripe down the breast and belly which gives the impression of an unbuttoned vest, and white patches between the wings and lower back. This flycatcher breeds in low densities throughout
All have cause to marvel at the sight of a gorgeous male Purple martin. Adult males are entirely glossy bluish-purple, although they may look black in poor light. Females and yearling males are grayish below and darker above with a paler forehead and nape. The world's largest swallow, martins are uncommon in Oregon. They nest both solitarily and colonially in nest boxes specially put up for them, in crevices in human-made structures, and in cavities in snags and pilings. They are an uncommon local summer resident, principally inhabiting the Coast Range and Willamette Valley. They are also locally common at
Adult frogs have moist bumpy skin that is tan or olive-green colored on their topsides. On their heads, backs, sides and legs, they have dark spots with light centers that darken with age. They also have red bellies and orange-red underlegs. Adult females grow to four inches in length and males to three inches in length. Columbia spotted frogs live in wet areas that provide abundant aquatic vegetation such as marshes, permanent ponds, lake edges and slow streams. When frightened, they hide in dense vegetation or under debris at the bottom of shallow wetlands. Adult frogs overwinter in springs, spring-fed
The Larch Mountain salamander is one of the rarest amphibians in the Pacific Northwest. This small woodland salamander has a reddish-brown or yellow black-spotted stripe along its back and has a pink belly. The Larch Mountain salamander is one of the lungless salamanders that has to breathe through its skin. Mature adults can grow to four inches in total length. This salamander like’s steep basalt talus (piles of volcanic rock fragments). Forested areas are also important because trees block out sunlight, allowing moss to grow on rock piles which keeps the ground damp all year. Larch Mountain salamanders prefer slopes
Del Norte salamanders are solid brown or black in color. Some individuals, especially younger salamanders, have a reddish-orange to red stripe along their backs, but it generally fades as they mature. As the species’ scientific name suggests, individuals have long bodies in relation to their short limbs. The Del Norte salamander is one of the lungless salamander species that breathes through it’s skin. They can grow to six inches in total length. Del Norte salamanders live in older redwood or Douglas-fir forests and commonly use rocky substrates rubble, talus (rock fragment piles) and rock outcroppings for cover. During hot and
