Diet and habitat   Range This list of mammals of Oregon includes all wild mammal species living in or recently extirpated from the U.S. state of Oregon or its coastal shores. The Northern Flying Squirrel is found in the Coast Range, Klamath Mountains, Willamette Valley, West Cascades, East Cascades and Blue Mountains. They range throughout Oregon and can live in a variety of habitats, from sea level up to 10,000 feet in elevation. Openings have always occurred in the forest. Their eggs and young sometime fall prey to raccoons and great horned owls. Traveling across the state, you would soon discover that Oregon is home to a wide range of trees. Range The western rattlesnake is found throughout Oregon, with the exception of the Coast and Cascade mountain ranges. It is preyed upon by other snakes, carnivorous mammals and raptors. Range Although it is possible to observe cougars in almost any habitat type, they are usually found in remote forested areas and often in dense vegetation, especially in winter. They also have a pointed snout and long, flexible fingers with sharp claws. Predators and threats Barely bigger than a golf ball, they average 3 to 4 inches in length and have a bronze-green back, a pale grey chest and belly, and green flanks. Southern Oregon, endangered in Washington; resides among dense sagebrush; rarely daytime; mostly active dawn/dusk (crepuscular); burrow dwellings; walks/scurries. Diet and habitat Endemic to northwestern Oregon; two subspecies described, see main article page; dwells among conifers. They produce one to eight young per year. Reproduction Description Adults average 9.5 to 10 inches in length, with an average wingspan of 16 inches and weigh between 9 to 12.5 ounces. Subspecies present in the region are discussed in the notes. & Shaughnessy, M. M. (2001). They are found primarily in western Oregon and inhabit riparian, mixed conifer, ponderosa pine and white oak forest types, preferring young forest stands for feeding and fawning and older stands for hiding and thermal cover. East of the Cascade Range the species is probably limited largely to the Ochoco, Blue and Wallowa mountains. Reproduction These seabirds nest on mossy platforms on the limbs of old tree stands, no more than 55 miles inland along Oregon’s Coast Range and Klamath Mountains. Garter snakes are significant predators because they have evolved a biochemical defense against the toxin. Reproduction Description It begins breeding in May and can produce up to two broods per year, with clutch sizes of two to eight eggs. It is the only hummingbird to spend the winter in northern climates. Unlike many other types of tree squirrels, they lack cheek pouches in which to hold food. Their beak is large and hooked. Predators and threats Diet and habitat Deer mouse breeding tends to be determined more by food availability than by season. Diet and habitat   The hairy woodpecker is preyed upon by hawks, weasels and martens. Generally, adults have a broad, fan-shaped tail with a red upper surface. Range Reproduction They breed in ponds, where the larvae and juveniles often hide in soft bottom sediments. During mating season, the males mate with several females.

The giant Pacific salamander can be found along Oregon’s west coast. Raccoons have few natural enemies in Oregon. Predators and threats They can be found throughout Oregon in open areas associated with riparian, mixed conifer, ponderosa pine, white oak, aspen and hardwood forest types, and in grasslands and agricultural areas. Assuming there is an adequate supply of prey, gray wolves can flourish in any environment. Reproduction The Willamette Valley, Klamath Mountains, West Cascades and Coast Range of Oregon. Range Range Reproduction The mountain lion can be found throughout Oregon, but primarily western Oregon. Animal Sounds is a mobile veterinary ultrasound service located in Oregon’s southern Willamette Valley. The male remains close by to supply the female with food. Gestation is 2 to 3 months. Local populations are threatened by habitat loss due to various forms of human development. For some time after the chicks fledge, the family group, including the parents and the young birds, remains together.
