Of Oregon's breeding seabirds, Leach's storm-petrel is the smallest, most pelagic, and flies the farthest offshore of any of Oregon's breeding seabirds to feed. It spends the non-breeding season in the subtropical and equatorial Pacific. It is the second most abundant breeding seabird in Oregon, and is rarely seen from land or close to shore. It comes to its breeding islands, where it nests in burrows, only under the cover of darkness. Its plumage is black and Oregon populations have a distinct white rump. Leach's storm-petrels are long lived birds characterized by long-term pair bonds and may breed yearly for…
The Black-backed woodpecker can often be found in the open expanses of a recent forest fire or the twiggy closets of a bark beetle outbreak. It may be heard before seen, with its accelerating drum ringing from a prominent snag or its snarling call. Its nest is often low in a tree; both living and dead trees are used, but may require heartrot for excavation of nest cavities. Nest trees are often smaller in diameter than those used by other cavity nesters. It is a rare to locally common resident near the summit and on nearby plateaus and ridges on…
California slender salamanders are a lungless species that has an especially long and slender worm-like body. They have reddish-brown stripes along their backs from head to tail. This stripe fades as the animal ages. Mature adults can grow to five-and-a-half inches in total length. In Oregon, this salamander usually lives in humid coastal conifer forests. In redwood forests, this salamander easily blends in with bark and other debris. During warm wet weather, California slender salamanders take cover just beneath the surface; if conditions are especially dry, salamanders may retreat deep into crevices, logs, stumps, or insect and worm burrows underground…
These large toads are well camouflaged in earth tones with dry bumpy skin that aids in protection from predators. Their color can be highly variable among individuals ranging from gray or reddish-brown to yellow or green. They have a light colored stripe that runs along the center of the back. Adult female toads are larger than males, growing to five inches in length. They live mainly on land in a range of habitats from forests to mountain meadows to desert flats. During the non-breeding season, they are nocturnal. They dig their own burrows in loose soil, use existing burrows or…
Adult Oregon spotted frogs have moist bumpy skin that is reddish-brown on their topsides. On their heads, backs, sides and legs, they have black spots with light centers that darken with age. They also have red bellies and orange-red underlegs. Adult females grow to four inches in length and males to three inches. Oregon spotted frogs live in wet areas that provide abundant aquatic vegetation such as marshes, permanent ponds, lake edges and slow streams. When frightened, they hide in dense vegetation or under debris at the bottom of shallow wetlands. Adult frogs hibernate during the winter in freeze-free seeps…
The Cascade torrent salamander generally has numerous medium-sized black spots and white-gray flecking along its tan back and sides and a bright yellow belly that has fewer spots. Adults can grow to just over four inches in total length. Cascade torrent salamanders spend their lives in and near permanent, cold, fast-flowing and clear water including headwater streams, waterfall splash zones and seeps in older coniferous forests. Adults need gravel streambeds or other gravel areas with constant and shallow water flow for foraging and cover. The Cascade torrent salamander is an Oregon Conservation Strategy Species in the West Cascades and Willamette…
The Western red-backed salamander is a woodland species and is small and slender. It has a wide stripe running from the head to the tip of the tail that can be yellow, orange, green or brown. Mature adults can grow up to just over four inches in total length. Western red-backed salamanders live in humid coniferous forests with mild winters. They find cover in rocky substrates, including talus (rock fragment piles), boulders and rock outcroppings. They may also hide under or in rotting logs, leaf litter and other forest debris. Like other woodland salamanders, this species breaths through its skin…
Adult frogs have moist bumpy skin that is tan or olive-green colored on their topsides. On their heads, backs, sides and legs, they have dark spots with light centers that darken with age. They also have red bellies and orange-red underlegs. Adult females grow to four inches in length and males to three inches in length. Columbia spotted frogs live in wet areas that provide abundant aquatic vegetation such as marshes, permanent ponds, lake edges and slow streams. When frightened, they hide in dense vegetation or under debris at the bottom of shallow wetlands. Adult frogs overwinter in springs, spring-fed…
The coloring of adult coastal tailed frogs often matches the color of local rocks ranging from brown or reddish-brown to gray with little flecks of yellow or gray. They have grainy textured skin that further enhances their camouflage. Male coastal tailed frogs have a short tail, the signature for tailed frogs. Adult males grow to one and three-quarter inches long and adult females to two inches long. They live in very shallow and heavily shaded water of fast running, small, permanent mountain streams with cold and clear water, rocky substrates and little silt in older forests. These streams are often…
The Rocky Mountain tailed frog’s coloring often matches the color of local rocks ranging from brown or reddish-brown to gray. They have grainy textured skin that further enhances their camouflage. Males have a short tail, the signature for tailed frogs. Adult males are slightly smaller than adult females that grow to two inches in length. Rocky Mountain tailed frogs are found in the water or close by it. They live in very shallow and heavily shaded water of fast-flowing, small, permanent streams in older mountain forests with cold and clear water, rocky substrates and little silt. These streams are often…
Adult frogs are gray or brown with yellow underbellies and thighs. Their color and grainy textured rough-looking skin helps camouflage them, making them hard to see among rocks. Adults can grow to three inches in length; males are slightly smaller than females. Foothill yellow-legged frogs live in or along edges of permanent streams and rivers with exposed rocky streambeds and off-channel waters that are slow flowing and quiet. In summer, they are likely to hide under rocks in streams or among clumps of vegetation along pools. They use rocks or debris at the bottom of the streams as refuge from…
The Norway rat is the largest member of the subfamily in Oregon. This heavy-bodied rat has a scantily haired, scaly tail shorter than the length of the head and body. The ears are membranous and lightly furred. The pelage is course, a grizzled brownish or rusty gray dorsally and dirty white to yellowish gray ventrally. Albino, melanistic, and spotted specimens are known to occur in free-living populations. This rat is distributed throughout the world in association with humans and in Oregon is found in most of the counties west of the Cascade Range and from some counties along the Columbia…
Rough-skinned newts were named for their dry granular skin―most other salamander species have moist smooth skin. A terrestrial adult newt has a brown head and back with a bright orange belly and can grow to almost eight inches in total length. Rough-skinned newts have a powerful neurological poison in their skin and eggs to protect them from predators. A milky white substance is released from glands when disturbed. Avoid hand-to-mouth contact after handling a Rough-skinned newt. Through the non-breeding season, terrestrial adults live in forested areas along the coast and through to the eastern foothills of the Cascades. They find…
Humpback whales are seen during their north and south migrations from northern waters to breeding grounds near Hawaii and also feeding offshore during the summer. Humpbacks have been documented travelling 3,000 miles between Alaska and Hawaii in as few as 36 days. They are usually five to 15 miles offshore, so they are most often seen by fishers. Humpback whales live in all major oceans from the equator to sub-polar latitudes. Humpbacks eat primarily krill and small fish and can consume 3,000 pounds of food a day. Humpbacks grow to 60 feet in length with a stocky body, an obvious…
