Siskiyou Chipmunk
The Siskiyou chipmunk (''Neotamias siskiyou'') is a species of rodent in the family Sciuridae. It is endemic to northern California and central Oregon in the United States. Anatomy and morphology The Siskiyou chipmunk is closest in appearance to Allen's chipmunk (''Neotamias senex'') and the yellow-cheeked chipmunk (''Neotamias ochrogenys'')''.'' Its coat is brown-gray, with a pattern of five dark brown and four gray stripes along its back; the central stripe tends to be blackish and darker in color compared to the other stripes. Additionally, ''Neotamias siskiyou'' have three brown and two gray stripes on each cheek. The specific appearance of the Siskiyou chipmunk varies due to the large geographic range the species inhabits, with larger and darker members found on the coasts compared to those found further inland. Distribution and habitat ''Neotamias siskiyou'' is found in northern California, in Humboldt and Del Norte counties, as well as in Oregon, in the Siskiyou mo ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, wh ...

Klamath River
The Klamath River (Karuk: ''Ishkêesh'', Klamath: ''Koke'', Yurok: ''Hehlkeek 'We-Roy'') flows through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. It drains an extensive watershed of almost that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upsi ...

Townsend's Chipmunk
Townsend's chipmunk (''Neotamias townsendii'') is a species of rodent in the squirrel family, Sciuridae. It lives in the forests of the Pacific Northwest of North America, from extreme southwestern British Columbia through western Washington and western Oregon. Townsend's chipmunk is named after John Kirk Townsend, an early 19th-century ornithologist. Description A large chipmunk, adults can be from nose to the tip of its tail. In much of its range, it is the only chipmunk; it can be identified by its tail which is grayish above and reddish below, and by its brown coloration with indistinct tawny stripes. Biology Townsend's chipmunk hibernates in regions where the winter is harsh, but in other parts of its range that have a more mild climate it can be active year-round. It is omnivorous, eating a variety of plants and insects and even birds' eggs. Townsend's chipmunks in the Oregon Coast Range have higher population densities in areas with dense shrubbery, especially salal ('' ...

Yellow-cheeked Chipmunk
The yellow-cheeked chipmunk (''Neotamias ochrogenys''), also known as the redwood chipmunk, is a species of rodent in the squirrel family, Sciuridae. It is endemic to areas near the coast of northern California in the United States where it inhabits coastal coniferous forest. Description The yellow-cheeked chipmunk is the largest species in the genus ''Neotamias'' and grows to a total length of including a tail of . It is a dark, tawny olive with five dark longitudinal stripes on the body, the central one along the spine being the most prominent, and three on the head, where the dark stripe running across the eye has pale stripes on either side. A pale patch of fur is found immediately behind the ear. The sides of the body are ochre which gradually fades to the paler underparts, where dark gray guard hairs are tipped with white. The bushy tail is dorsoventrally flattened, the upper surface being the same color as the body and the underside being reddish-brown to orange. The guar ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Chipmunk
Chipmunks are small, striped rodents of the family Sciuridae. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia. Taxonomy and systematics Chipmunks may be classified either as a single genus, ''Tamias'', or as three genera: ''Tamias'', of which the eastern chipmunk (''T. striatus'') is the only living member; ''Eutamias'', of which the Siberian chipmunk (''E. sibiricus'') is the only living member; and '' Neotamias'', which includes the 23 remaining, mostly western North American, species. These classifications were treated as subgenera due to the chipmunks' morphological similarities. As a result, most taxonomies over the twentieth century have placed the chipmunks into a single genus. However, studies of mitochondrial DNA show that the divergence between each of the three chipmunk groups is comparable to the genetic differences between '' Marmota'' and '' Spermophilus'', so the three genera classifications ha ...

Rogue River (Oregon)
The Rogue River ( tol, yan-shuu-chit’ taa-ghii~-li~’, tkm, tak-elam) in southwestern Oregon in the United States flows about in a generally westward direction from the Cascade Range to the Pacific Ocean. Known for its salmon runs, whitewater rafting, and rugged scenery, it was one of the original eight rivers named in the Wild and Scenic Rivers Act of 1968. Beginning near Crater Lake, which occupies the caldera left by the explosive volcanic eruption and collapse of Mount Mazama, the river flows through the geologically young High Cascades and the older Western Cascades, another volcanic province. Further west, the river passes through multiple exotic terranes of the more ancient Klamath Mountains. In the Kalmiopsis Wilderness section of the Rogue basin are some of the world's best examples of rocks that form the Earth's mantle. Near the mouth of the river, the only dinosaur fragments ever discovered in Oregon were found in the Otter Point Formation, along the ...

Siskiyou Mountains
The Siskiyou Mountains are a coastal subrange of the Klamath Mountains, and located in northwestern California and southwestern Oregon in the United States. They extend in an arc for approximately from east of Crescent City, California, northeast along the north side of the Klamath River into Josephine and Jackson counties in Oregon. The mountain range forms a barrier between the watersheds of the Klamath River to the south and the Rogue River to the north. Accordingly, much of the range is within the Rogue River – Siskiyou and Klamath national forests, and the Pacific Crest Trail follows a portion of the crest of the Siskiyous. These mountains are not the highest of the Klamath Mountains, but due to the relief so close to the Pacific Ocean, the peaks receive significant precipitation from the ocean, including wintertime snow on the peaks. Western canyons can receive over of rain in some winters and are densely forested, while eastern areas are more arid. The greatly va ...

Sciuridae
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, cognat ...
