Terns are generally associated with marine environments and salt marshes, but the Forster's tern inhabits freshwater areas. During the breeding season this graceful bird is eastern Oregon's resident small white tern. Typical of terns, the Forster's employs a dramatic hunting method of plunge-diving into shallow waters to capture small fish, the bird sometimes submerging completely. This is an uncommon but highly visible colonial breeder east of the Cascades. Hear the call of the Forster's tern Photo by Dave Budeau, ODFW

This snake is found in meadows and at the edges of clearings in forests. It prefers areas with dense vegetation but, when basking, can be found in open areas or on talus slopes. It occurs in wooded areas on the floor of the Willamette Valley and has been found in the Rogue Valley. This garter snake is commonly found in suburban areas and city parks. The Northwestern garter snake feeds mainly on slugs and earthworms, but also takes insects, small salamanders, frogs, fish, small mammals, and possibly nestlings of ground nesting birds. Photo by J.

Much variability in coloration exists in the common garter snake but the best identifying characteristic is a stripe down the middle of the snake's back. While the common garter snake frequents wet meadows and forest edges, it occurs in a variety of habitats far from water, including open valleys and moist coniferous forest. Smaller snakes eat earthworms, but adults feed on a variety of vertebrate prey, including frogs, toads, salamanders, birds, fish, reptiles, and small mammals. Invertebrates, including slugs and leeches, are also eaten. Photo by Dave Budeau, ODFW

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.

Western pond turtles prefer marshes, streams, rivers, ponds and lakes. They need sparse vegetation nearby for digging nests and like to bask on logs. Population declines are due to habitat loss, degradation of nesting areas by invasive plants, competition from non-native turtles and disease. Predators include raccoons and invasive bullfrogs and fish. Western pond turtles are Oregon Conservation Strategy Species in the Coast Range, East and West Cascades, Klamath Mountains and Willamette Valley ecoregions. Photo by Simon Wray, ODFW

This species is found in a variety of habitats. To make matters more confusing, four subspecies are found in Oregon, each of which has somewhat different habitat preferences. All can be found in moist areas such as marshes and lake or stream margins, but two may occur some distance from water. The diet varies among subspecies; the more aquatic forms feed on fish, frogs, tadpoles, and leeches, which are eaten in the water. Terrestrial forms take frogs and toads, but also lizards, small mammals, salamanders and slugs. Photo by David Bronson, ODFW

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…

While recreationally harvesting green crab has been allowed for decades, the Oregon Fish and Wildlife Commission recently increased the daily bag limit to 35 crab. This gives recreational shellfishers an opportunity to help native shellfish by taking more of these invaders home. European green crab are an invasive species in Oregon. While recreational harvest is allowed (35 per day), harvesters must correctly identify these crabs (see below) as they often are mistaken for native species. Commercially harvesting green crab is prohibited. Green crab: Compete with native crabs for food. Larger green crab may eat smaller native shellfish. May disturb eelgrass…

Commonly found along beaches and about estuaries, this large, ponderous bird is a conspicuous member of the summer coastal community, easily recognized by its large size, massive bill, and brownish plumage. Highly gregarious, it often forms large flocks; regularly observed foraging over the ocean just offshore. Brown pelicans often join mixed flocks of birds attracted to schools of small fish. They are common spring, summer, and fall visitors along the Oregon coast. Brown pelicans are an Oregon Conservation Strategy Species in the Nearshore ecoregion.

Heermann's gulls, the warm-water gulls of summer and fall, accompany Brown pelicans as they fly north each summer. Although most feed along the shore or in the ocean, some feed on tide flats. They often steal food from Brown pelicans. They may take fish directly from the pelicans' bills immediately after a dive or claim food that pelicans have located, discarded, or disturbed. This gull is common on the outer seacoasts, beaches, bays and estuaries. They are strongly associated with outer coasts and adjacent ocean waters, usually within a few miles of shore. A few wander inland during the fall…

A slender, orange bill, pearl gray upperparts, and fringed black crest adjoining a white face and neck indeed render this graceful hunter from the south elegant. The foreheads of adults turn white in post-breeding plumage, their usual state in Oregon. These terns frequent quiet waters or lagoons when diving for fish, but also dive in calm ocean waters. They roost with flocks of gulls and other terns on coastal spits, estuarine sandbars, and on mudflats close to bay mouths. Virtually all records of the Elegant tern in Oregon are coastal or within half a mile of shore. None have been…

Though less conspicuous than Great blue herons, Green herons are well-established residents of western Oregon. They are distinguished by small size, glossy greenish-black cap and back, yellow legs, blackish-green wings, gray underparts, and dark red neck. One of the few tool-using birds, Green herons are experts at making and using baits and lures, such as bread crusts, mayflies, earthworms, sticks, and feathers to catch fish. The Green heron is an uncommon but regular migrant and summer resident throughout west and south central Oregon. Detection of nests is difficult and breeding status uncertain in some areas due to its secretive habits…
