Inconspicuous and master of stealth, the Least bittern inhabits densely vegetated deep-water marshes, making observations rare and difficult; its call is often the only way to detect this secretive species. The smallest of herons, its long neck and legs make it appear larger. The crown, back and tail of male birds is greenish black; purple-chestnut on female. Neck, flanks, and underparts are brown and white and the wings buff. It is a rare spring and summer resident in larger freshwater marshes of eastern Oregon and a very rare spring through fall visitor in the Rogue and Willamette valleys. At Upper…

The Barred owl expanded its range from the eastern United States. It was first reported in Oregon in the early 1970s and has since spread to forested areas throughout most of the state. Sometimes confused with the closely related Northern spotted owl, the Barred owl is large with grayish-brown and white feathers and stripes on its chest and throat. It is easily distinguished from the Northern spotted owl by the pronounced horizontal barring across the throat and upper breast, and vertical brown streaks on the lower breast and abdomen. The Barred owl is now a permanent resident in forests of…

Noteworthy as a generalist, the Black-chinned hummingbird appears in a wide variety of habitats, including lush river bottoms, urban settings and desert canyons. Below the male's velvety black gorget is an iridescent purple band that can also look black in poor light. At rest, the wingtips are relatively broad and curved, unlike any other North American hummingbird. A rare to locally common resident east of the Cascades, it is least common in Klamath and Lake counties. Summer habitat in eastern Oregon includes canyons, juniper woodlands, and desert riparian zones. In the foothills of the Blue and Wallowa Mountains, it's found…

Features: Their eyed-side is greenish-brown to dark brown or black with lighter blotches. Their blind side is white to milky-white. They have a large, stout but flat body, shaped like an elongated diamond . Pacific halibut have been known to reach 500 pounds, but on average are 40 pounds. Habitat: Halibut are a large flatfish and so they spend much time near the bottom of the ocean looking above for food. They prefer chilly water and are primarily found in the Gulf of Alaska. Technique: Boat anglers use heavy rods to fish on or near gravel bottoms in water 150-500…

The male Red-winged blackbird, sentry of the marsh during the breeding season, continually announces its territory to all present with its oak-a-tee song, and tenaciously defends against flyby predators. The male is territorial, polygynous, larger than the female, and glossy black with a broad bar of red-orange, bordered with yellow, on wing writs. Females are less conspicuous in behavior, light brown, with a heavily streaked breast, and buffy supercilium. This is one of the most abundant and studied birds in North America. The Red-winged blackbird occurs west of the Cascades in Oregon from coastal and valley locations, and east of…

Pheasants, grouse, quail and turkey are all upland game birds that are chicken-like and ground-dwelling. Wild turkeys are the largest upland game bird in Oregon.

With a widespread distribution and affinity for open habitats, the Killdeer is one of the most common and recognized birds through much of North America. Killdeer are large for a plover and easily distinguished from other North American plovers by their characteristic two black or brownish-black breast bands. Killdeer are well known for their loud and persistent call of "kill-dee, kill-dee," heard at all times of day or night on both the breeding and wintering grounds. Killdeer often nest close to human activities. Adults perform an elaborate and exaggerated broken-wing display to lure humans and potential predators away from their…

The American badger is a medium-sized, powerfully built carnivore strongly adapted for digging. The body is flattened and the legs are short but stout; the toes of the forefeet are partly webbed and equipped with long, curved claws; the hind feet are shaped like miniature shovels; and each eye is equipped with a membrane that can be extended to cover it. The ears are rounded and densely covered with fur but seem large in comparison with those of many digging mammals. The tail is short and brushlike. Dorsally, the long, shaggy pelage is mottled grayish blending on the venter to…

The River otter is adapted for both terrestrial and aquatic environments. The heavily muscled, somewhat cylindrical body is thickest at the thorax and tapers posteriorly to a thick, flattened tail. The body tapers to a blunt and slightly flattened head. The legs are short and powerful; and the toes are webbed. The eyes are small, forwardly directed and set high on the head. The underfur is grayish, short, and dense, and overlain by longer, stiff and shiny guard hairs. The dorsum is brown and the venter a lighter brown or tan; the lower jaw and throat are whitish. In Oregon…

Features: Yellow perch are golden, with six to nine dark vertical bars. They have two well-separated dorsal fins; the second fin has two or three spines. Lower fins are yellowish-orange and, unlike walleye, yellow perch do not have canine teeth. Maximum size in Oregon exceeds 3 pounds and 18-inches long. They are prolific spawners, often resulting in an overpopulation of stunted fish. Habitat: Yellow perch prefer lakes, reservoirs and slower moving streams that have cool, clean water and ample vegetation. Perch bite readily and are therefore popular with young and novice anglers. Technique: In the spring and fall, find yellow…

Features: Channel catfish are pale bluish-olive above and bluish-white below with a deeply forked tail, dorsal and pectoral spines, and an adipose fin. Like all other catfish, channel catfish have “whiskers” or barbels extending from the chin and upper jaw. Young fish have a varying number of small black spots over much of the body, while older fish may be partially or entirely without spots. Maximum size in Oregon approaches 40 pounds, but most are less than 10 pounds. Habitat: Channel catfish in western Oregon are limited to the Columbia River, lower Willamette River, and a few ponds in the…

Features: As the name suggests, these fish have rosy red strip along their sides. Other identification clues include large, profuse black spots on the body and orange and yellow tints along the belly. Habitat: Redband trout are a subspecies of native rainbow trout that have adapted to the arid, desert conditions of eastern Oregon. During drought years distribution constricts as streams dry and become uninhabitable. Trout re-colonize these streams during wet cycles, expanding the distribution. Prime trout waters are clear, clean and cold. Good trout stream habitat is complex, consisting of an array of riffles and pools, submerged wood, boulders…

In Oregon, the opossum is considered an invasive species. The Virginia opossum is a cat-sized mammal with a pointed nose, unfurred, black, leathery ears with white edges; beady eyes; a hind foot with an opposable hallux (big toe); and a naked scaly tail. It was introduced in Oregon between 1910 and 1921. Populations were established in northwestern Oregon apparently from releases of animals brought to the state as pets or novelties. Small streams, forest communities, and agricultural lands planted to a variety of crops are typical of many habitats occupied by Virginia opossums in Oregon. They are active nocturnally and…
