Characteristic of open country and cold weather, the Rough-legged hawk can be found soaring over exposed terrain or perched on utility poles across much of the state in winter. The rough appearance of its legs comes from the feathers covering their length, an adaptation that provides extra warmth in frigid weather. In flight, dark wrist patches and belly help identify this large buteo, though like other hawks it is subject to much variation in plumage. From a distance it frequently appears to have a frosty upper half. It often hovers over fields while hunting, a behavior that is rare among…

High overhead at the top of the rimrock in Oregon's desert country, the White-throated swift swoops, soars, and darts about erratically, hunting and catching insects. At great speed, it disappears into a crevice on a cliff without appearing to slow down. Its long, strong claws enable it to crawl deep inside these crevices to roosting and nesting areas, which often cannot be seen from the entrance. This bird is a locally common to abundant breeder, primarily on eastern Oregon cliffs. It is an occasional spring and sporadic fall migrant in western Oregon along the coast, in the Willamette Valley, and…

One of the most startling sounds in the black of night is the loud, harsh call of the Barn owl as it flies over field or marsh in search of small rodents. They are white to tan beneath with fine spotting ranging from almost none to fairly extensive. The face has a well-defined facial disc that acts as a parabolic dish collecting the faint sounds of its prey, allowing it to hunt successfully in total darkness. Male and female Barn owls are similar in appearance though the female is somewhat larger. The Barn owl is a fairly common permanent resident…

Almost strictly nocturnal, the Western screech-owl hunts discreetly at night and roosts during the day in dense woodlands, its perfectly streaked plumage allows it to pass as tree bark. These habits make it difficult to see, and it is more common than many are aware. It is a small owl with yellow eyes and feathered ear tufts. It exhibits geographic variation in plumage color and pattern: both gray morphs and brown morphs occur in the Pacific Northwest. Sexes are alike. The Western screech-owl is a fairly common year-round resident in lower-elevation woodlands throughout Oregon. It is usually found below 3,000…

This tiny owl has a reputation as an aggressive predator on everything from mice and voles to birds and mammals over twice its size. Coloration is highly variable with brown and gray morphs. In Oregon, color varies from dark brown in coastal mountains to gray in eastern Oregon, with an intermediate pale grayish-brown form in the Cascade mountains. About the length of a White-crowned sparrow, it has striking yellow eyes, dark vertical streaks on the breast and abdomen, and dark "eyespots" on the back of the head. It is primarily diurnal and can often be approached quite closely when it…

A thick body, small head and coloration similar to a killer whale make this dolphin easy to recognize. Dall’s porpoise is mostly black with a large white patch on the belly and flanks. The small dorsal fin is partly white and the trailing edges of the tail are frosted white. About seven feet long and weighing around 400 pounds, Dall’s live only in the north Pacific. Dall’s are the fastest of all small cetaceans and can swim at up to 35 miles per hour, almost as fast as a killer whale. When swimming at the surface they create a characteristic…

The Long-tailed weasel is the larger of the two weasels in Oregon, but smaller than the other member of the genus, the mink. Males are considerably larger than females. The head is flattened and somewhat triangular; the body and neck are elongate and almost cylindrical; the legs are short, and the tail is long. The summer pelage is brown dorsally; the venter is yellowish to orangish except for a white chin and sometimes one or more scattered brown spots. The tip of the tail is black. The pelage is molted twice annually. In the Cascade Range and eastward through the…

Features: The Pacific sanddab is left-eyed, meaning both eyes are on the left side of the body. The eyed-side is dull light brown, mottled with brown or black, and sometimes yellow or orange. The blind-side is off-white to tan. They have an oval shaped body with large scales. They can grow to be 16-inches long and up to 2 pounds, though most weigh less than 1/3 pound. Habitat: As you probably guessed, sanddabs like to hang out on sandy bottoms. They are most abundant at depths of 20-50 fathoms, and are common in shallow coastal waters from British Columbia to…

As the winter day turns to dusk, White-tailed kites drop into their roosts and Short-eared owls rise to take their place on the local hunting grounds. White-tailed kites in Oregon often roost communally in winter, but they disperse in early spring and are more difficult to find during the breeding season. By day, they are conspicuous as they hover over rural fields searching for prey, in part because of their pale appearance. The tail is entirely white, as are the head and the underparts. Dark crescents on the underwing can be seen when a bird is flying or hovering. Above…

Raccoons are found throughout the state, excluding high mountains and desert regions. They have adapted well to residential life because of their flexible diet and nocturnal nature. Raccoons are opportunistic feeders and have a diverse diet that includes insects, plants, and small animals—but also unnatural foods, like pet food and trash, when they have the chance. Raccoons are notorious for getting into garbage cans and eating pet food left on a porch or food left out at campsites. Raccoons that are fed by people often lose their fear of humans and may become aggressive. Do not attempt to feed or…

Peregrine falcons are among the most charismatic and noted of the world's birds. They are described as the fastest animal on the planet, and have been recorded reaching speeds in excess of 240 miles an hour in dives after prey. They are one of Oregon's boldest raptors, and have been observed usurping active Golden eagle nest sites, stealing fish from Ospreys and ground squirrels from adult Bald eagles who stray into their territory. It has, for perhaps 4,000 years, been used by falconers because of its skill in capturing game birds in tandem hunts with humans. Peregrines are medium-sized raptors…
