The Bohemian waxwing is a nomadic species, invading locations with fruit-bearing trees or shrubs. Referred to as a "roving bands," their name reflects this view of their unpredictable and seemingly carefree lifestyle. Very sociable birds, they exhibit pronounced flocking habits in the winter, and frequently give themselves away with their constant gentle seeping or trilling voice. Their sleek profile and elegant, almost exotic coloration also distinguish these birds. Hear the song of the Bohemian waxwing Photo by Kathy Munsel, ODFW

The Pacific shrew is the only shrew in Oregon without a tine on the anteromedial surface of the first upper incisor but with a posteriomedial ridge visible in anterior view through the gap between the incisors. It is a large brown shrew with the third unicuspid smaller than the fourth. The species is often found in moist wooded areas with fallen decaying logs and brushy vegetation. It is endemic to Oregon and is distributed as two disjunct populations: one in the Coast Range from Cascade Head, Tillamook County, south to Coos Bay, Coos County and eastward to Philomath, Benton County…

The vagrant shrew can be distinguished from all other congeners in Oregon by the combination of the upper unicuspids wider than long in ventral view. It is light medium brown on the dorsum, light pinkish-gray on the sides, and white on the venter, bases of hairs on all three areas are neutral very dark-gray. The tail is weakly bicolored (dark brown over white) in juveniles. The vagrant shrew occurs throughout the state except in the Columbia Basin. It tends to be more of a generalist than most Oregon shrews in terms of habitat affinities, nevertheless, it usually is found in…

In Oregon, the nutria is considered an invasive species. The nutria is a large rat-like semiaquatic rodent. The species has a hunched body; a round, nearly hairless tail; a valvular mouth and nose; and pentadactyl feet with naked soles. The toes of the hind feet, except for the hallux, are included in a web. As an adaption to the aquatic environment, the eyes, nostrils, and small ears are set high on the sides. The pelage consists of long, course guard hairs and soft, dense underfur. Overall, the color usually ranges from dark brown to yellow-brown. The muzzle is frosted with…

Fun facts about our bats Oregon's bats eat only insects. An adult bat eats about 1,000 insects every hour! Bats hang upside down because it gives them an ideal position for take-off. Bats can fly 20 to 30 miles an hour and travel more than 100 miles a night. A baby bat is called a pup. Young bats can fly between two and five weeks of age. Bats are the only flying mammal.

This small swift is best known for its quick flight and dazzling aerial agility, perching only when nesting or roosting. It is aerodynamically designed for fast speeds with long, pointed wings, short stout legs, and a compact body. The Vaux's swift is a transient and summer resident nesting in older forests and brick chimneys statewide except the southeast part of Oregon.

When glimpsed in the deep shadows of its preferred densely forested habitat, this secretive thrush resembles a plump robin. But a clearer view will reveal the distinctive fieldmarks of a dark breast band, orange eyebrows, and orange wingbars. As striking as its plumage is its unmistakable song: a succession of single drawn-out, ventiloquial notes, given at different pitches that pierce the fog and dense foliage of its favored haunts in lush coastal and montane old-growth forests. In Oregon, it breeds throughout the Coast Ranges and in the Cascades. It is a fairly common breeder in low-elevation hemlock and spruce forests…

The moose is the largest member of the family Cervidae. The pelage is blackish or dark brownish grading to dark gray or grayish brown on the venter and leg. The muzzle is broad and overhanging, the palmate antlers of adult males are massive, and a "bell" (waddlelike flap of skin on the throat) is present. The first moose to come to Oregon wandered south from Washington or west from Idaho across the Palouse Prairie. They stayed to establish a herd in the Blue Mountains north of Elgin, and today there are an estimated 50 adults and calves in the area…

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…
