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…
Adult Northern leopard frogs have smooth skin that is green or brown and covered with dark brown spots outlined with white rings. Females grow to just over four inches in length; males are slightly smaller at just over three inches. They live in and near various water sources with abundant vegetation such as wet meadows, marshes, riparian areas and moist, open woodlands. These frogs use the vegetation, such as grasses, sedge, weeds or brush, as cover from predators. During the winter, they need ponds or slow-running streams for hibernation. Photo from ODFW
Swans, ducks and geese belong to the Anatidae family and occur on all continents. Special oils let their feathers shed water, so they are adapted for swimming and floating, and some are even talented divers. For tips on discouraging geese from overwhelming your yard, check our Living with Wildlife, Birds page.
The majestic trumpeter swan is the largest of our native waterfowl and one of the heaviest flying birds in the world with males sometimes exceeding 30 pounds. Historically hunted to the brink of extinction, it was recognized as an endangered species long before there was an Endangered Species Act, and its recovery is a conservation success story. The adult's snow-white plumage with contrasting black bill and feet and 8-foot wingspan define this magnificent bird. Their neck is as long as their body and is used to reach food at the marsh bottom. In spring, the trumpeter swan is a locally…
Of several swans found in Oregon, the tundra swan is by far the most common during the non-breeding season. It is most readily distinguished from the similar-appearing trumpeter swan by voice, although subtle differences in physical appearance and behavior can separate the two with difficulty. It is a fairly common transient throughout the state but most abundant at large bodies of water and wetland complexes east of the Cascades including the Malheur National Wildlife Refuge and the surrounding Harney Basin, Summer Lake Wildlife Area and the Klamath Basin.

The drake wood duck is the most colorful of North American ducks. The brown hen has similar features including a crest, distinctive white eye-ring, white belly and purplish-blue iridescence on wing coverts and speculum. Both sexes have a prominent tail that can be a field mark in flight. As their name implies, they are associated with timbered wetlands, nesting in cavities and sometimes even feeding in trees. Hens utter a fairly wide range of un-duck like sounds, but most common is a loud wee-e-e-e-k, wee-e-e-e-k. It is a regular breeder in the Willamette Valley, along slow reaches and backwaters of…
The drake gadwall is a large mostly gray dabbling duck. Adult drakes have a black bill, buff head, gray body, and black upper and lower tail coverts. Hens are nondescript brown ducks with a spotted, yellowish-orange bill with black edges. Gadwalls are unique among dabbling ducks in having a partly white speculum which can be observed in flight. Common vocalizations include the deep, reed-like sounds of the male and the female's quacking, similar to but more nasal and higher pitched than the mallard hen. It is an abundant breeder locally in eastern Oregon and an uncommon breeder in western Oregon…
This foreign visitor is regularly found in Oregon among wintering flocks of American widgeon. Drakes are easily distinguished from American wigeon drakes by reddish brown head, gray flank, and lack of green eye stripe. Hens are similar to American Wigeon hens and difficult to distinguish. The call of the male is a shrill whistling, whe'e you; the female's voice a low purr or croak. It is a rare to uncommon visitant east of the Cascades.

Wigeon drakes are beautifully marked with white pate, green eye stripe, purplish breast and flanks, white belly and wing covert patch, and iridescent black/green speculum. The grayish hen shows white on the wing covert patch. Drakes give a three-note whistle and get progressively noisier as spring approaches and courting flights begin. Medium sized flocks are common in fall and winter, and like geese, will be found grazing pastures, park lawns, and golf courses. It is a rare to locally common breeder in eastern Oregon and rare in summer in western Oregon. It is a common to abundant migrant and wintering…
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 blue-winged teal is one of Oregon's least common ducks. It is a small, warm-weather duck usually found in Oregon only from late spring until the weather cools in early fall. Except for adult drakes in alternate plumage, blue-wings are difficult to distinguish from cinnamon teal. For that reason its status in Oregon is less clear than that of other ducks. Adult blue-wing drakes have a gray head with white crescent between the eye and bill. Hens and young of both species are nondescript small brown ducks, but show the prominent blue wing-covert patch in flight. It is an uncommon…
The bright rusty plumage of the male cinnamon teal, a bird of western North America, is a visual delight. In flight, both males and females show powder blue in the wings as they fly fast and low, timed at nearly 60 miles per hour. They weigh only about one pound. They are a common breeder throughout the state except in western Oregon and the high Cascades. They are most common east of the Cascades. Hear the call of the cinnamon teal Photo by Maxine Wyatt
