The bright yellow, red, and black plumage of the male Western Tanager, so conspicuous in open situations is very obscure in forested areas where it tends to blend into the shaded foliage. The species perhaps is best known in migration when it visits city parks, orchards, and other open urban and suburban areas. It is attracted to birdbaths but seldom to bird feeders. It breeds in open coniferous forests and mixed coniferous and deciduous woodlands, primarily in mountains. They usually nest in conifers - rarely deciduous trees - at varying heights, usually well out on a branch, often at the…

With four wing-beats each second pushing them to 62 miles per hour, brant are the fastest and strongest geese in flight and among the swiftest of all large birds. Black brant comprise the vast majority of brant occurring in Oregon. These small geese have smoky black backs and bellies, and dissected white collars and white around the tails provide striking contrast. The black brant can live up to 20 years and are resilient enough to ride out storms on the open ocean. In Oregon, wintering numbers along the coast have seen a 50 percent reduction from previous years due to…

The gregarious Tricolored blackbird is one of North America's most intensely colonial breeders, forming dense, non-territorial, noisy colonies. A highly synchronized nesting system exploits secure nesting locations and rich food supplies that change from year to year. In Oregon, breeding colonies are scattered and intermittent at specific locations, though sites used during consecutive years may be in the same general area. The Tricolored blackbird breeds most consistently in Klamath and Jackson Counties. Small colonies and summering residents have been found in the Willamette Valley; during fall and winter they are rare. Most retreat south to California in winter, while some…

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…

Sporting the form of a curlew, this medium-sized marsh wader is almost always found in flocks, flying in formation and quacking like ducks. Their long, down-curved bill complements their long neck and legs. Although their feathers appear black, a closer look will reveal an iridescence of bronze, purple, maroon, and green. They are named for their "white face" which appears in alternate plumage as a narrow border of white feathers along the edge of their reddish-purple facial skin, delineating a mask around the red eye. The White-faced ibis has extended its breeding grounds in Oregon to wetlands in Harney, Lake…

The Sharp-shinned hawk is North America's smallest and most migratory accipiter. As a hunter of songbirds (and sometimes young chickens) it historically endured harsh reproach, and was often depicted as a blood-thirsty villain, even by some ornithologists. Across the U.S., many thousands were shot in the first half of the 20th century. But prevailing attitudes have changed, and today a glimpse of this slender, secretive hawk darting through the treetops is more likely to elicit admiration than malice. Adult plumage, nearly identical to the slightly larger Cooper's hawk, consists of slate gray back and wings, breast and sides barred with…

This cavity-nesting thrush is one of three bluebird species found only in North America. Previously abundant in western Oregon, the Western bluebird suffered a precipitous decline through degradation of habitat and avian competition. The male has a cobalt blue head and throat, blue wings and tail edged with dusky brown, russet breast and flanks, gray-blue belly and undertail coverts. Female colorations are subdued: head and throat gray, back gray-brown, wings and tail pale blue, breast and flanks pale russet. The amount and brightness of blue and russet are brighter on older birds. The Western bluebird breeds in open habitats with…

The skies near favored stopover locations are filled twice annually with the sights and sounds of these geese as they migrate between Arctic breeding grounds and wintering areas farther south. Snow geese share very similar all-white plumage and black wing tips with the less common Ross's goose. These are Oregon's only wild white geese. It is predominantly a spring and fall migrant, especially abundant in large wetland and agricultural complexes such as Malheur National Wildlife Refuge, Silvies River floodplain in Harney County, Lower Klamath National Wildlife Refuge and Klamath Wildlife Area. Wintering snow geese in Oregon are found primarily along…

The Bald eagle is one of eight species of sea-eagle worldwide, and the only sea-eagle found throughout North America. It is one of the most studied North American birds. Large size, wingspan of six-and-a-half to eight feet, and the contrast of white head and tail, and yellow eyes, beak, and leg, to dark brown body and wings make the adult Bald eagle one of our most distinctive raptors. Six age-related plumages have been recognized; adult plumage is acquired at four-and-a-half to five years of age. Sexes have similar plumages, but females are larger than males, and the sex of individuals…

The American marten is weasel-like with a long body and pointy face. The legs are short; the toes, including the pads, are completely furred; and the nails are semiretractile. The tail is bushy and long. The pelage in winter is luxuriant, with a dense underfur and sparse covering of guard hairs. The color varies, but usually is a golden brown shading to dark brown on the feet and tail; the head is lighter. The throat and chest are splotched with orange or yellow. A small dark stripe extends upward from the medial corner of each eye, giving the appearance of…
