The montane shrew is slightly larger and has a slightly longer tail than the vagrant shrew. It is distinctive in that the third unicuspid is smaller than the fourth. It occurs as a small population near the Columbia River and along the Pacific Coast in Clackamas, Clatsop, Columbia, Hood River, Multnomah, and Tillamook counties and as a series of populations at higher elevations in Baker, Crook, Grant, Harney, Union, Wheeler, and Wallowa counties.

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 water shrew is a large shrew with a very dark gray to black dorsal pelage, a white venter and throat, and a sharply bicolored tail. It occurs, in Oregon, as disjunct populations in the Wallowa, Blue, Ochoco, Strawberry, Steens, and Hart mountains and in the High Cascade Range west and downslope to McKenzie Bridge, Lane county. It is almost always found near water. Undercut banks, exposed tree roots, and boulder-strewn streamsides vegetated by willow, willow-grass, or willow-alder associations seem to be prime habitat.

Preble's shrew is the smallest shrew in Oregon; adults commonly weigh less than a dime. The pelage is medium dark-brown to very dark-gray on the dorsum and silvery gray on the venter. The tail is bicolored, medium dark-brown on the dorsal surface, white on the ventral surface and darkening toward the tip. In Oregon, it has been found in Deschutes, Grant, Klamath, Lake, Harney, Malheur, and Wallowa counties. Its habitats include marshes, along streams, dry bunchgrass, and wet, alkaline habitat. Grasses and sagebrush are common to most habitats.

The fog shrew is the largest of the brown shrews in Oregon. Its range extends from Taft in Lincoln County east to near the eastern boundaries of Linn and Lane counties (except it is absent in the Willamette Valley) and southward along the west slope of the Cascade Range and in the Coast Range and Siskiyou Mountains. They are found in alder/salmonberry, riparian alder, and skunk cabbage marsh habitats and less often in conifer habitats.

Trowbridge's shrew is a medium-sized shrew, distinguished from other Oregon shrews by its dark-brown or grayish black pelage on both dorsum and venter, and its sharply bicolored tail, white below and dark brown or grayish black above. In Oregon, its range is west and south of a line connecting Parkdale, Hood River County; Pine Grove, Wasco County; Alder Spring, Lane County; Diamond Lake, Douglas County; Gearhart Mountain, Lake County; and Lakeview, Lake County. It occurs in all stages of the coniferous forest from old growth to recent clear-cuttings. Photo by Don Henise, Flickr

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

The shrew-mole is the smallest talpid in Oregon. The pelage is black; the eyes are rudimentary. The tail is about 50 percent of the length of the head and body, fat, sparsely haired, blunt ended, covered with transverse annular rows of scales and tufted. In Oregon, the species occurs as far east as Brooks Meadows, Hood River County; Indian Ford Campground, Deschutes County; and Fort Klamath, Klamath County. It is most abundant in moist sod-free ravines with deep, black-silt soils with high humus content and covered with a layer of dead leaves and twigs. Dominant vegetation in these areas is

The broad-footed mole is intermediate in size among Oregon moles. It occurs south of a line connecting Hugo, Josephine County; Prospect, Jackson County; Crater Lake, Klamath County; and Fort Rock and Goose Lake, Lake County. Photo from Panegyrics of Granovetter, Flickr

The coast mole is the smallest of the moles in Oregon. It occurs in Baker, Umatilla, Grant, Crook, Union, Sherman and Wasco counties east of the Cascade Range and throughout most areas west of the Cascade Range, except it is absent from much of the Willamette Valley. Photo by Peter Paquet, Flickr

Townsend's mole is the largest talpid in Oregon. In Oregon, it is restricted to the interior valleys and coastal regions west of the foothills of the Cascade Range. It occupies pastures, prairies, and shrub habitats in lowlands and river flood plains. The highest densities were recorded in pasture areas in Tillamook County. Photo by J. Maughn, Flickr

California myotis is an acrobatic flyer. It is dark brown to blond with dark ears, and feeds on moths and flies. Early in the summer, a female joins a maternity or nursery colony where she gives birth to one offspring. In winter, these bats roost in mines, caves and buildings. The California myotis is an Oregon Conservation Strategy Species found throughout the state except for the Columbia Basin. Photo by ©Michael Durham

The long-eared myotis is pale brown to strawberry. It is a slow flier and hovers around trees and rocks to catch flies, moths and wasps. It is primarily a bat of coniferous forests in much of Oregon but may occur far from trees in shrub-steppe regions of the state. It forages in openings in dense forest, between the trees beneath the canopy in ponderosa pine, and over willow-bordered creeks. The species is known to enter dwellings and other buildings through open windows and doors, and to forage on moths therein. The long-eared myotis often day roosts in buildings, but may

This bat is brown to reddish brown and has relatively long forearms. It gets its name from the fringe of hairs along the bottom of its tail. It roosts in trees, snags, buildings, caves, rocks, cliffs and bridges. It likes beetles and moths but will eat spiders and crickets. The fringed myotis occurs in the Coast Range from Jackson County to Clatsop County and in the northeastern corner of the state. It's an Oregon Conservation Strategy Species in seven of the nine ecoregions. Photo by ©Michael Durham

The hoary bat has a wingspan of nearly 16 inches. It has dark fur tipped with white, a dark mask on its face, a yellow-orange throat and round ears edged in black. This bat roosts in branches of trees and likes to feed around outdoor lights. Hoary bats migrate south in winter, returning to Oregon in the spring. This bat usually bears twins. Hoary bats are found at scattered localities over most of the region west of the Cascade Range and in montane regions east of the Cascade Range. They are an Oregon Conservation Strategy Species in all ecoregions except

This bat, found in older forests, has a wingspan of about 10 inches. Its fur is glossy black, tipped with white. It forages over ponds, streams, meadows and roads, often flying very low and roosting behind loose tree bark. Maternity roosts of the silver-haired bat are found in trees. This bat usually bears twins. The silver-haired bat occurs statewide in Oregon except for most of the Columbia Basin and is an Oregon Conservation Strategy Species in all ecoregions except the Nearshore ecoregion. It is primarily associated with coniferous forests, including the juniper woodlands in the southeastern portion of the state

The big brown bat is a relatively large bat with a wingspan of 13 to 14 inches. Its dark color and slow flight help with identification. They are more likely to be active in cold weather than other bats and prefer human structures for roosting. The big brown bat occurs throughout the state. In eastern Oregon it forages over the forest canopy, along roads through the trees, along the forest edge, over forest clearings, and along cliffs and canyon streams. In western Oregon, the species is usually associated with coniferous and deciduous forests. Photo by ©Michael Durham

This is a medium-sized bat with large, long ears. It is gray, brown, or black and generally active only after full darkness. Townsend's big-eared bat is very vulnerable to human disturbance, and its numbers are declining. In Oregon, it is classified as a State Sensitive Species. It's also an Oregon Conservation Strategy Species in all ecoregions except Nearshore. Never disturb this bat if you are in a cave. Photo by ©Michael Durham

This is a large, pale bat with huge ears, large eyes and a dog-like face. Its wing beat is slower than most bats. It emerges late at night to feed primarily on the ground, eating large beetles, crickets, and even scorpions. Pallid bats can walk on the ground and are immune to a scorpion’s sting. The pallid bat is uncommon and is found mostly in arid regions in canyons in southwestern and eastern Oregon. It's an Oregon Conservation Strategy Species in the Blue Mountains, Columbia Plateau, East Cascades, Klamath Mountains, and Northern Basin and Range ecoregions. Photo by ©Michael Durham

The Brazilian free-tailed bat is a fast-flying, medium-small bat with long narrow wings and a tail. It survives the cold winters in Oregon by staying in heated buildings instead of hibernating or migrating, often sharing these quarters with other bat species. Roseburg may be the most northern part of this bat’s range. Photo by ©Michael Durham
