Within wintering flocks of Horned Larks in the valleys of eastern Oregon, and along flats bordering coastal estuaries in the fall, it is sometimes possible to find flocks of this large arctic-breeding sparrow. Their habit of running along the ground in a crouch rather than flying makes them a challenge to observe, but in flight their characteristic rattling call is unmistakable. Otherwise, in fall and winter plumage, they appear as brownish streaked sparrows. In flight their dark tail with white sides is conspicuous. Along the outer Oregon coast, the Lapland longspur is an uncommon but regular fall migrant, especially at…

This long-distance, relatively late-arriving migrant to Oregon is associated with shrub-dominated habitats, especially riparian willow thickets. The plumage has subtle tones of olive-green and gray; the species is without a visible eye-ring but the characteristic sneezy, abrupt song reveals its presence. The Willow flycatcher breeds in western Oregon from sea level along the coast and interior to above 5,000 feet west of the Cascades summit. In eastern Oregon it breeds mostly above 1,000 feet from Klamath to Burns and also Lake County and Union County. The habitat of breeding Willow flycatchers is characterized by dense shrubs and/or tall herbaceous plants…

The drake gadwall is a large mostly gray dabbling duck. Adult drakes have a black bill, buff head, gray body, and black upper and lower tail coverts. Hens are nondescript brown ducks with a spotted, yellowish-orange bill with black edges. Gadwalls are unique among dabbling ducks in having a partly white speculum which can be observed in flight. Common vocalizations include the deep, reed-like sounds of the male and the female's quacking, similar to but more nasal and higher pitched than the mallard hen. It is an abundant breeder locally in eastern Oregon and an uncommon breeder in western Oregon…

Large and primarily white, the American white pelican has the longest wingspan of any bird in Oregon. It also has an enormous orange bill, and flies with neck withdrawn. During the breeding season the top of the bird's head becomes dusted with black and a horn grows on the upper mandible; this projection serves as a target for aggressive encounters to avoid injury to the essential bill pouch, but is shed after the eggs are laid. This pelican makes unusually long flights for feeding and migration, and at great distances, soaring flocks have been reported as UFOs. In Oregon, it…

This is one of the most widespread and familiar waterbirds in Oregon. It is the largest heron in North America, standing approximately four feet tall. It is slate gray with a white crown, cheeks, and throat, rusty thighs and a uniformly yellow bill. Adults develop long gray-white plumes on chest, neck, and back during breeding. Juveniles have similar plumage but may be distinguished by absence of breeding plumes, a dark crown, and dark upper bill. Great blue herons frequent many habitats from shallow areas of marshes, lakes, streams, and oceans, where they feed on fish, amphibians, and aquatic invertebrates; to…

This thrush-like ground-foraging warbler breeds from southeast Yukon and eastern British Columbia across Canada and through the eastern United States and locally elsewhere east of the Rocky Mountains. It migrates east of the Rocky Mountain to winter in Middle America. It is occasionally found in winter in its breeding range and in California. Small numbers regularly occur in western North America. Most Oregon records are from the southeast part of the state. Spring records range from early-May to mid-June. Fall records are fewer than in spring, and occur between late August and early September. Hear the song of the Ovenbird…

The pelage of this chipmunk is marked with five dark and four light stripes on the dorsum; the middorsal stripe is usually black and nearly always darker than the other four dark stripes. The sides of the face are marked with three brown and two light gray stripes, a patch behind the ear is light gray. The tail is blackish frosted with ochre dorsally and rusty brown ventrally. Allen's chipmunk produces a call of a rapid series of three or four to as many as 10 syllables. In Oregon, it occurs in forested areas along the eastern part of the…

The foothills of interior southwestern Oregon come alive in late April with the bold song of this bright yellow warbler. Here it seems every brushy area or mixed conifer/hardwood forest with dense undergrowth has at least one male singing just beyond the reach of binoculars. Although it can be found in many other places in the state and in a variety of habitats, nowhere else is it as common. Nashville's are one of the few warblers in the West to nest on the ground. They occupy diverse shrub communities, often including or adjacent to a relatively short or open tree…

This is a large and power falcon. The majority of Gyrfalcons seen in Oregon are immatures or adults of the "gray" type, but there are several reports of "white" birds. The Gyrfalcon is a regular winter visitant to Oregon. The majority of sightings come from coastal and Willamette Valley lowlands near waterfowl concentrations. Individuals have been seen chasing and feeding on geese, ducks and gulls. Gyrfalcons forage by flying low over the ground and flushing prey, then often giving spectacular tail chases. If a bird refuses to flush the hunt is usually unsuccessful. East of the Cascades it occurs around…

Oregon's owls are mostly nocturnal, hunting for insects, fish, frogs, birds, mice and other small mammals in the night. Their hoots, screeches and calls can be heard after dark or early in the morning. Owls don't build nests, but instead use tree cavities, nests created by other species, naturally occurring structures or human-made nest platforms. The Western burrowing owl nests underground in abandoned dens dug by squirrels, prairie dogs and badgers. Learn more about Oregon's owls.

Oregon has a variety of raptors, from the diminutive Sharp-shinned hawk to our nation's symbol, the Bald eagle. Some of these birds of prey are migratory, while many live here year-round and can be seen hunting along rivers, roadside posts and fields.

The piñon mouse is the largest member of the genus in Oregon. It is characterized by its enormous ears. Hair color varies geographically; overall, in central and eastern Oregon it is a pale-buff color with a wash of black on the dorsum, whereas mice from southwestern Oregon are bright ocherous on the shoulders and flanks and a dirty brown on the dorsum. In Oregon, the piñon mouse has been found in Josephine, Jackson, Klamath, Lake, Deschutes, Jefferson, Grant, Crook, and Harney counties. East of the Cascade Range it is almost always associated with western juniper in rimrocks. In southwestern Oregon…

An Oregon native, sooty grouse occupy the coniferous forests of western Oregon, the eastern slopes of the Cascades, the Blue Mountains of northeastern Oregon, and the Klamath Basin and South Warner Mountains. Preferred habitat includes timber edges, open timbered slopes and mountain meadows, often adjacent to springs or other sources of water. They are often associated with berry producing areas such as chokecherry thickets. Hear the call of the sooty grouse Photo by ©Keith Kohl, ODFW
