Worldwide, frogs and toads are in trouble because of habitat loss, pollution, pesticides, climate change, diseases, the pet trade and competition from invasive species. Many of Oregon's 12 native species of frogs and toads are listed as Oregon Conservation Strategy Species of concern. Frogs and toads belong to the same animal group but are very different. Toads have dry, rough and bumpy skin covering a wide body while frogs are slender with smooth, moist skin. Frog eyes are higher on the head than toads and are rounder and bulging. And there's a reason we play "leap frog" - frogs take…

Brandt's cormorants nest colonially on offshore islands and mainland cliffs and are the most common of the cormorants on the Oregon coast in summer. In the breeding season, males are easily distinguished by their intense blue gulag pouches, displayed with a skyward pointing of the bill. They also have wispy white plumes along the side of their head and on their back, which show well against the solid black of the rest of their plumage. In bright light they have a green iridescence. During all seasons they can be distinguished from the two other Oregon species by buff-colored feathers that…

This tiny sandpiper is the rarest of the regularly occurring "peeps" in Oregon. Only a handful of individuals are reported in Oregon each year, mostly during fall migration and usually in mixed flocks with Least and Western Sandpipers. Like the Western sandpiper, the Semipalmated has black legs, but its bill is generally shorter, straighter and more blunt. Well-known as a transoceanic migrant, the Semipalmated sandpiper may be one of the fastest flying of the long-distance shorebirds. It is a rare irregular spring transient throughout Oregon, and a very uncommon coastal and rare inland fall transient. It is usually found inside…

This medium-sized woodpecker may be found in virtually any forested area in Oregon. It is found primarily in mixed-conifer and ponderosa pine forests, as well as adjacent deciduous stands, especially during the breeding season. Hairy woodpeckers feed on beetles, ants and other insects, spiders, miscellaneous plant matter, elderberry corn and mast (mostly acorns), and a few seeds. They are regular visitors to suet feeders and have been observed drinking from hummingbird feeders in central Oregon. It is a resident in forests throughout Oregon with the exception of juniper. Common throughout most of this range, but uncommon to fairly common along…

The Wolverine is the largest terrestrial mustelid in Oregon that, to some degree, resembles a small bear. It is powerfully built with a broad, dog-like head; short round ears; small eyes; a slightly humped back; relatively short legs and a bushy, somewhat drooping tale. The pelage consists of a dense, wooly, crimped under fur overlain by course, stiff and somewhat shaggy guard hairs. Fur on the tail is about twice as long as on the body. The base color is blackish brown with a pale brown stripe extending along the sides from the head or shoulders to the base of…

This small shorebird moves along the sand by foot rather than flight. It has a distinct black cap behind a white forehead, a dark line though the eye, and an incomplete black breast band. Males have darker and more distinct breeding plumage than females; both sexes loose coloration during late summer. It is the only shorebird that regularly breeds on Oregon's beaches. East of the Cascades, the Western Snowy plover is a summer resident breeding on alkaline flats and salt pans. On the Oregon coast, this species is found year-round between Heceta Head and Cape Blanco. Western snowy plovers are…

The red tree vole is a medium-sized vole. It is uniquely colored among North American voles: bright orangish-red to cinnamon on the dorsum, silvery gray (often with some light orangish hairs) on the venter, and a tail pale orangish on the venter grading to black on the dorsum. This vole is endemic to western Oregon. It occurs at moderate elevations on the west slope of the Cascade Range southward as far as the Douglas-Jackson county line and in the Coast Range to the Oregon-California border. It is largely arboreal and builds nests on suitable foundations (commonly nests of birds or…

Oregon's native turtles are in trouble. Invasive, non-native turtles such as the red-eared slider and snapping turtle compete with Oregon's turtles for food, habitat and nesting sites. Our native turtles are also preyed upon by bullfrogs and are affected by habitat loss and degradation. Check out this video to learn more about Oregon's native turtles and invasive turtles.

This medium-sized, shy grebe has bright white cheeks that contrast sharply against a dark crown and rust red neck during the breeding season. An aquatic bird, it breeds in lakes and ponds, usually in forested areas. In Oregon, it is found in waters with hardstem bulrush intermixed with open water over five feet deep. Five to 20 birds at Rocky Point in the Upper Klamath Lake National Wildlife Reserve form the only consistent breeding population in Oregon. The red-necked grebe reaches its greatest numbers during winter along the coast. The red-necked grebe is an Oregon Conservation Strategy Species in the…

The rock scallop ( Crassadoma gigantea) lives in the swift current shallows of Oregon's nearshore rocky reefs. Due to the coloration at its hinge, it is also known as the purple hinged scallop. These highly specialized scallops cement themselves to rocks, primarily at depths from 10 to 150 feet. They feed on microscopic plankton they filter from the water and reproduce via broadcast spawning. In order for spawning to be successful, they need to be close to one another. For this reason, it is best to harvest solitary rock scallops and minimize harvest pressure on dense aggregations which are more…

The California kangaroo rat is the largest kangaroo rat in Oregon, but is only of moderate size within the genus. It has a moderately broad face, relatively large ears, and awl-shaped lower incisors. The tail is 150 percent of the length of the head and body. It is the darkest-colored kangaroo rat in Oregon. The pelage of the dorsum is composed of hairs with dark-gray bases, a narrow dark-buff band and black terminus. The venter, feet, upper lip,; and base, sides, and tip of tail are white and there is a white spot above each eye and behind each ear…
