Invasive species are animals and plants that are not native to an ecosystem and that cause economic or environmental harm. Not all non-native species are invasive, however many become a serious problem. They can aggressively compete with Oregon's native wildlife for food and habitat.

The Sierra Nevada red fox is a montane red fox subspecies. Its presence in Oregon was confirmed in 2015, specifically in the Mt. Jefferson, Mt. Washington, and Three Sisters Wilderness Areas. The Sierra Nevada red fox is smaller than the red fox and averages about eight pounds. This fox has three color phases: silver (black), "cross" color phase and the more familiar red. The Sierra Nevada red fox is an Oregon Conservation Strategy Species in the East Cascades, Klamath Mountains and West Cascades ecoregions. Research continues on this species in the Oregon Cascades. Biologists captured and radio-collared several Sierra Nevada…

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…

When mention is made of ducks, many people first think of the mallard. Its ability to tolerate human disturbance and adapt to urban as well as rural habitats make it the Northern Hemisphere's most abundant and widespread waterfowl. Females are mottled-brown, with dark brown stripe through the eye, orange bill with black splotching and have yellowish-orange legs. Immatures resemble adult females until males acquire nuptial plumage usually by mid-November. Males enter the eclipse molt in June and resemble hens until mid-September. Wings of both sexes have a violet-blue speculum bordered in front and behind by a pronounced white stripe. They…

The Eastern gray squirrel is the smallest member of the genus in Oregon. This squirrel was introduced into Oregon and can now be found in Salem, Portland, Milwaukie, and Vale. All populations in Oregon have been found in urban areas. This squirrel is active throughout the year, activity restricted to daylight hours. Photo from Washington Fish and Wildlife

Searching for frogs and salamanders is a great way to introduce kids to the wonders of Oregon's wildlife and the great outdoors. Learn more about their various habitat needs and you'll increase your chances of seeing one of these unique species. Remember to leave no trace to preserve their habitat. Check out our fun facts on Oregon's frogs.

This is one of the most widespread and familiar waterbirds in Oregon. It is the largest heron in North America, standing approximately four feet tall. It is slate gray with a white crown, cheeks, and throat, rusty thighs and a uniformly yellow bill. Adults develop long gray-white plumes on chest, neck, and back during breeding. Juveniles have similar plumage but may be distinguished by absence of breeding plumes, a dark crown, and dark upper bill. Great blue herons frequent many habitats from shallow areas of marshes, lakes, streams, and oceans, where they feed on fish, amphibians, and aquatic invertebrates; to…

The American bullfrog is a non-native invasive frog that survives and reproduces very successfully in Oregon. Bullfrogs aggressively compete for food and living space with our native frogs. They eat many types of native wildlife including other frogs, young pond turtles, and ducklings. Bullfrogs can lay almost 10 times more eggs than native frogs and can quickly out number them.

This is the largest native quail in North America and one of the least understood. Males and females have identical plumage characterized by distinctive white flank barring and prominent vertical head plumes. Their eastern Oregon range appears reduced from historical accounts. Mountain quail are considered occasional in Union and Wallowa counties. They have also been observed along many of the tributaries of the John Day River in Wheeler and Grant counties and some in Wasco, Jefferson, Deschutes and Crook counties. In western Oregon, they are found in most forested mountainous areas generally above 1,640 feet, but may move to valley…

These elegant shorebirds are found as often in dry or damp upland areas as they are on mudflats or beaches. The plain brown immature birds of autumn become spangled with black and gold as breeding approaches. It is an occasional to uncommon migrant in western Oregon (mainly coastal) and locally rare, irregular migrant in eastern Oregon, with most reports at Malheur National Wildlife Refuge, in the Klamath Basin (summer) and in Umatilla County.
