The Chipping sparrow is a small and slender sparrow that has a distinctive sharp chip note and simple, trilling song. Breeding adults display a chestnut crown, a black eye-stripe, and crisp white eyebrow. After nesting season, both male and female lose their distinctive bright cap for a streaky dull brown head pattern that is similar to other winter sparrows. It is a common summer resident in open forests and drier woodland edges throughout Oregon and is especially abundant in the Blue Mountains. The Chipping sparrow is an Oregon Conservation Strategy Species in the Willamette Valley ecoregion. Hear the song of

Although not brilliantly plumaged, the conspicuous Song Sparrow is one of the more regularly seen birds in Oregon. Defensive and curious, when approached it readily announces its presence with loud chips and often excitedly rises to a conspicuous perch to confront the interloper. The Song sparrow is well named as both male and female have a variety of songs that may be heard at any time of year, and juvenile birds begin to sing full songs within two months of hatching. The Song sparrow is a common and widespread resident of western Oregon. Hear the song of the Song sparrow

This dark, medium-sized finch with gray and pink highlights is the darkest of the rosy-finches and one of Oregon's rarest breeding birds. It is found in summer in montane areas above timberline, where loose swarms of these birds seem to blow like leaves among isolated cirques, cliffs, and hanging snowfields. In Oregon it breeds on Steens Mountain and may breed occasionally in the Wallowa Mountains. Winter distribution is poorly known, but birds have been found on the lower east side of Steens Mountain and in the Alvord Desert in winter and rarely in central Wallowa County. Hear the song of

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 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

The Little pocket mouse is one of the smallest rodents in North America and certainly the smallest in Oregon. The dorsal pelage is pinkish buff to ocherous buff with overlying blackish hairs; the venter is buff. The tail is bicolored. In Oregon, this mouse occurs in Harney and Malheur counties. They exhibit their greatest activity from spring through autumn and spend a large portion of their lives in burrows below the surface of the ground. In winter, they remain underground continuously, relying on stored seeds for energy. When active on the surface, a large portion of their time is spent

The golden-mantled ground squirrel doubtlessly is the most distinctively marked ground squirrel in Oregon; a white stripe bordered on both sides by a black stripe extends from the shoulder to the hip. From nose to nape above the eye, the head is russet. The back between the stripes is grizzled dark grayish-brown becoming less grizzled on the rump; lateral to the stripes the color grades to a light buffy-gold on the venter. The face, shoulders, front legs, and feet are a bright orangish-gold. This ground squirrel occupies the east slope of the Cascade Range and most of central Oregon, and

The world population of this species, which probably does not exceed 25,000 pairs, is quite low for a seabird. Nevertheless, these are the common light-bellied shearwaters off Oregon in summer. They are larger, bulkier, and fly more deliberately than the usually much more abundant sooty shearwaters with which they associate. They are uniform gray-brown above; the underparts are white; the vent and underwings variably smudged with dusky. The pinkish bill is dark-tipped and the feet are pink. It is a common summer visitor and very common fall transient offshore on shallow shelf waters. It is usually seen seaward, approximately five

Few seabirds have been labeled "stunning;" but with their graceful flight, boldly patterned upperparts, and brilliant white underparts, these birds truly are one of the most beautiful in Oregon waters. They have a black cap, wings angled forward, long body and tail, and a unique dark 'M' pattern against light gray back and wings. Often seen in small groups mixed among other more abundant shearwaters, they sometimes form pure flocks all flying in gracefully synchronized flight. While regular in Oregon in late fall, they are still uncommon enough to excite observers when encountered at sea. Photo by Tony Morris, Flickr

This graceful tern, with its aerodynamic body and streamlined wings, is infrequently seen from land in Oregon. It is most often encountered at sea as it makes one of the most incredible journeys in the animal kingdom, migrating from the Arctic to the Antarctic and back again each year, a journey of nearly 22,000 miles. A medium-sized bird with a reddish bill, it has a black cap and nape, and a white throat and cheek shading to a light gray body. It is a common offshore transient in Oregon waters and an occasional migrant along the coast. The bulk of

The Northern flicker is larger than most woodpeckers in Oregon. It is primarily lighter shades of brown and gray with black markings: spotted underparts, barred back, and a broad necklace. Its wing linings and undertail range from salmon to yellow, and the rump is white. Males have a red or black mustache. Northern flickers may be encountered in almost any terrestrial habitat, but are generally most abundant in open forests and forest edges adjacent to open country. They venture into nearby habitats, including towns and farms but typically avoid dense forests. It is a common resident throughout Oregon. Hear the

The Pileated woodpecker was the model for the cartoon character, Woody Woodpecker. It is a large black-and-white bird with a bold red feathered crest and distinctive call. You may hear its powerful drumming before you see it. In Oregon, its habitat includes older forests in the Blue Mountains, East and West Cascades, Klamath Mountains, Willamette Valley and Coast Range ecoregions. They prefer mature forests and younger forests with large snags and logs, requiring large diameter snags for nesting and foraging. Pileated woodpeckers are an Oregon Conservation Strategy Species in the Blue Mountains ecoregion. Hear the call and the drumming of

The Dusky flycatcher inhabits open conifers, conifer-hardwoods, or shrubs in the mountains of Oregon. A medium-sized Empidonax with a small head and rounded crown, the upperparts are grayish olive to grayish brown, the throat grayish, and the underparts mostly whitish with an olive-gray wash (sometimes yellowish). The wings have two narrow, usually whitish wingbars. The narrow white eye ring and pale lores give the appearance of spectacles. This flycatcher is a common summer resident in most of its breeding range in Oregon. It is found the entire length of the Cascades, but habitat is limited west of the summit in

This striking songbird is best known for its habit of impaling prey on thorns and barbed wire, or wedging items in a v-shaped branch for easier handling and storage. The Loggerhead shrike breeds in open habitats east of the Cascades where they are rare but regular in the winter, especially at low-elevation sites. They are uncommon and declining in northeast Oregon. West of the Cascades, there are usually a few records each year during fall, winter, and spring in open habitats of the coast and the Willamette, Umpqua, and Rogue valleys. The Loggerhead shrike is an Oregon Conservation Strategy Species

This is the larger of Oregon's two shrikes, and the more likely to be seen in winter. Most of those seen in Oregon are hatch-year birds wearing brownish plumage in the fall and graying as winter passes. Adults stand out from young of the year with more crisp gray, black, and white plumage. Shrikes inhabit open landscapes. They resemble and act like small raptors, however, they capture and kill prey with a hooked bill rather than with talons. The Northern shrike is an uncommon to locally common visitor in open habitats statewide. It is absent some years along the southern

Ensatina salamanders are a lungless species with a short body and yellow or orange legs. There are two sub-species in Oregon: the Oregon ensatina ( E. e. oregonensis) is solid red, orange, brown or tan, while the painted ensatina ( E. e. picta) has small yellow, black or white spots on the back and tail. Ensatinas grow to just over four inches in total length. Ensatinas live in humid forests, woodlands and other areas with woody debris. They hide under logs, bark piles at the base of snags (standing dead trees), stumps and even woodpiles in residential areas for cover

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
