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: 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…

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…

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…

Flocks of these big, brown, plain sparrows are a common sight in winter in western Oregon. By early spring their faded head markings become a beautiful gold, black and white, and their plaintive descending songs become frequently heard from almost any large brush pile. They are an abundant migrant in western Oregon, less common farther east, and abundant in winter throughout the Willamette Valley.

Although quite common in the U.S., the Black-crowned night-heron's nocturnal and crepuscular feeding habits can make it difficult to locate. Its habitat consists of marshes, lakes, rivers, and other wetlands, where it feeds mostly on fish. It is a thick-billed, medium-sized, stocky heron with relatively short neck and legs. Adults have a black back and cap which contrast with the pale gray or whitish underparts. Immatures have brown backs with large pale spots and heavily streaked underparts. A distinctive choking squawk call is often heard at dusk. It is a fairly common summer resident east of the Cascades where it…

Vireos and shrikes are predatory song birds. Their bills are strong and hooked to kill and dismember prey including insects and small birds, mammals and reptiles. These birds hunt from fences, wires and treetops and sometimes hang captured prey on thorns to eat them later.

The ears of the pygmy rabbit are short, rounded, and covered with long silky hairs inside and out; the tail is small and covered with hairs possessing wide buffy bands with narrow blackish tips above and below; and the feet are short, densely furred below, and colored a light orangy-buff. In Oregon, pygmy rabbits have been found east and south of a line connecting Klamath Falls, Fremont, Redmond, and Baker City. This rabbit is closely tied to habitats dominated by big sagebrush. The Pygmy rabbit is an Oregon Conservation Strategy Species in the Northern Basin and Range ecoregion. Photo from…
