These small gray-and-white sandpipers are commonly seen on beaches from early fall through late spring running in and out along the surf's edge. Buffier, spangled juveniles can be seen in late summer but the stunning rufous breeding plumage is less often seen and can be starling and confusing. The larger size, larger bill, and different habits of the Sanderling help distinguish it in all plumages from other small sandpipers. It is common to locally abundant on open sand beaches from fall through spring. Statewide, it is a rare to locally uncommon migrant inland, most often reported along the Columbia River…
Perhaps the most enigmatic hummingbird found regularly in Oregon, the Broad-tailed hummingbird has so far eluded documentation of its breeding in the state, likely due to identification uncertainties and the remoteness of its preferred habitat. Primarily a Rocky Mountain species, its hard-to-define breeding range seems to reach its limit at Oregon's eastern edges where reports of this beautiful and rare species arise each summer. The relatively large adult male has a rose-red gorget and green plumage with no dorsal Rufous coloration. Females and immatures are nearly indistinguishable in the field from those of the more common Rufous hummingbird. Hear the…
Blue whales are occasionally spotted off Oregon, but usually no closer than 10 miles offshore. These whales are part of the Eastern North Pacific population that range from Alaska to Costa Rica. They migrate between feeding areas along the west coast of the United States and Canada and breeding and calving grounds off Mexico and Central America. They are thought to be among the most endangered of the great whales. Photo by NOAA
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.
This diminutive owl is one of the smallest in North America, with a body mass of about 1.9 ounces. It has dark eyes, brown plumage with darker and reddish variegations, and small ear tufts. The Flammulated owl is unique among owls in the Pacific Northwest in that it preys almost exclusively on insects and is a neotropical migrant. Additionally, the pitch of its rather ventriloquial hoot is among the lowest of all North American owls. The Flammulated owl breeds on the eastern slope of the Cascades, in the Blue and Wallowa mountains, and in small numbers in the mountains of…
Because of its association with old forests, this inconspicuous, dark brown owl has become one of the most controversial birds in the Pacific Northwest. The dark eyes and creamy white mottling on the breast and abdomen are distinctive, as is the lack of fear of humans. Both adults and young will typically allow humans to approach within a few feet, and it is not unusual for curious juveniles to follow hikers through the woods. The Northern spotted owl is a permanent resident in forested regions of western Oregon, from the coastal mountains to the eastern foothills of the Cascade Range…
The Least flycatcher closely resembles the Hammond's flycatcher, but its distinctive voice and choice of habitat help to identify calling birds. It was formerly an unexpected vagrant west of the Rocky Mountains, but since 1981 it has become recognized as a regular migrant and local summer resident in the state. It is found in deciduous groves along streams and in wet lowlands. It desires a deciduous overstory with at least some low brushy undergrowth. It is regular migrant and local summer resident in the state of Oregon with the spring migration from May to mid-June. The majority of sightings are…
The largest of Oregon's grebes, these have a long white neck, black cap, bright red iris, long strait bill, dark back, bright white breast, and they appear tailless. While excellent divers, they are unable to walk on land because their body weight is forward of their legs. Differences in appearance between western and Clark's grebes are subtle. In the western grebe, the black cap typically extends down to the eye whereas white facial plumage extends slightly above the eye on the Clark's grebe, but this is not always diagnostic in winter. The western grebe is a common breeder in eastern…
The yellow-pine chipmunk is one of the smallest in Oregon, only slightly larger than the least chipmunk. Its face is marked with a dark stripe, followed laterally by two alternate light and dark stripes. The outermost light strip is nearly white. It occurs on the east slope of the Western Cascades and eastward through most of the remainder of Oregon, except it is absent from most of the Columbia Basin and much of southern Harney, eastern Malheur, and southern Baker counties. Its range also extends westward in the Siskiyou Mountains in southern Jackson and Josephine counties. Ponderosa pine seems to…
This sturdy-looking bird has a large head, short tail, and massive conical bill adapted for seed eating. The male plumage features bold patches of lemon yellow shading into olive, then brown and black, with white secondaries creating a flashy wing-patch easily seen in flight. The male's bill is chalky white in winter, but changes in early spring to a pale green that matches the new growth at the tips of spruce boughs, where they often nest. Many encounters with this species are of individuals heard flying high overhead, leaving the observer with little else to note. The Evening grosbeak is…
The kit fox is the smallest canid that occurs in Oregon. It has the typical canid conformation: the body is slim, the legs are long and thin, and the ears are large and erect. The tail is about 40 percent of the total length and is tipped with black, but has no dark mane on the dorsal surface. The feet and legs are whitish interiorly, light rusty-brown posteriorly. The dorsum is grizzled brownish-gray medially blending to grizzled gray then to light buff laterally and finally to white on the chest and venter. The head and posterior surface of the ears…
This cavity-nesting thrush is one of three bluebird species found only in North America. Previously abundant in western Oregon, the Western bluebird suffered a precipitous decline through degradation of habitat and avian competition. The male has a cobalt blue head and throat, blue wings and tail edged with dusky brown, russet breast and flanks, gray-blue belly and undertail coverts. Female colorations are subdued: head and throat gray, back gray-brown, wings and tail pale blue, breast and flanks pale russet. The amount and brightness of blue and russet are brighter on older birds. The Western bluebird breeds in open habitats with…
Although the least numerous scoter on the continent, it is the most common scoter along the Pacific coast south of Alaska and winters by the thousands off Oregon. Adult males' plumage, black except for white patches on the forehead and nape, yields attention to the bill, a swollen white, red-orange, yellow, and black wedge feathered squarely along its base. The highly visible standard advertises male's presence for up to a mile. Dark-billed adult females and subadults are dark brown above and paler brown below, with two indistinct light patches on the cheeks and sometimes on the nape. A flattened head…
This small, rich-brown wren is only slightly larger than a quarter, and has a tail quite short for a wren. A quiet observer in the forest will see these birds hop in and out and all over logs, snags, shrubs, twigs, and limbs on the forest floor. It has been said that the song of this bird is larger than the bird itself. The Winter wren breed from Coos County southward and in eastern Oregon in the Blue and Steens mountains. It retreats from high altitudes in winter where snow pack is heavy. Migration probably occurs throughout the state, but…
The Long-tailed weasel is the larger of the two weasels in Oregon, but smaller than the other member of the genus, the mink. Males are considerably larger than females. The head is flattened and somewhat triangular; the body and neck are elongate and almost cylindrical; the legs are short, and the tail is long. The summer pelage is brown dorsally; the venter is yellowish to orangish except for a white chin and sometimes one or more scattered brown spots. The tip of the tail is black. The pelage is molted twice annually. In the Cascade Range and eastward through the…
The bobcat is the smallest wild felid in Oregon, with females being considerably smaller than males. The bobcat is about twice the size of a domestic cat, but its legs are longer, its tail is shorter, and its body is more muscular and compact. The feet are relatively small and the bobcat is not well adapted to negotiate deep snow. In general, the variously spotted pelage is yellowish with grayish overtones in winter and with reddish overtones in summer, reflecting the two annual molts. The ears are black with a large white spot and are equipped with short black tufts…
This is the largest native quail in North America and one of the least understood. Males and females have identical plumage characterized by distinctive white flank barring and prominent vertical head plumes. Their eastern Oregon range appears reduced from historical accounts. Mountain quail are considered occasional in Union and Wallowa counties. They have also been observed along many of the tributaries of the John Day River in Wheeler and Grant counties and some in Wasco, Jefferson, Deschutes and Crook counties. In western Oregon, they are found in most forested mountainous areas generally above 1,640 feet, but may move to valley…
