The gopher snake occurs in a wide variety of habitats, from deserts and grasslands to woodlands and open forests. It frequents agricultural regions, especially where there is brushy cover such as fence rows. Diet varies according to size, with young eating insects, lizards, rodents, and birds and their eggs. Adults can take larger prey, occasionally as large as rabbits. Photo by Simon Wray, ODFW

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…

These big, medium-brown sparrows with variable grayish faces and heavily streaked or blotch undersides can be found in summer at higher elevations across much of the state except the Coast Range. Darker brown birds from more northerly breeding populations are common in western Oregon in winter, often coming to feeders, where they scratch like towhees for seed on the ground.

Terns are generally associated with marine environments and salt marshes, but the Forster's tern inhabits freshwater areas. During the breeding season this graceful bird is eastern Oregon's resident small white tern. Typical of terns, the Forster's employs a dramatic hunting method of plunge-diving into shallow waters to capture small fish, the bird sometimes submerging completely. This is an uncommon but highly visible colonial breeder east of the Cascades. Hear the call of the Forster's tern Photo by Dave Budeau, ODFW

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…

This is a large and power falcon. The majority of Gyrfalcons seen in Oregon are immatures or adults of the "gray" type, but there are several reports of "white" birds. The Gyrfalcon is a regular winter visitant to Oregon. The majority of sightings come from coastal and Willamette Valley lowlands near waterfowl concentrations. Individuals have been seen chasing and feeding on geese, ducks and gulls. Gyrfalcons forage by flying low over the ground and flushing prey, then often giving spectacular tail chases. If a bird refuses to flush the hunt is usually unsuccessful. East of the Cascades it occurs around…

This small greenish flycatcher is easily overlooked in the moist, shady forests where it makes its summer home. It is a common to abundant breeder in forests of the Coast Range and west Cascades below about 4,000 feet and a common transient in western Oregon. The Pacific-slope flycatcher is most easily detected and identified by voice, but there is incongruence between published descriptions of vocalizations and some birds heard in the field lessens the certainty of identification to species, especially those in eastern Oregon.

One of the characteristic birds of woodlands and city streets is this loud, colorful jay. Its bright blue-and-white-plumage and shrill calls are quite distinctive. It is closely related to the Steller's jay and hybrid individuals have been noted where their ranges overlap. It is an opportunistic forager of small animals and invertebrates, but is predominantly a vegetarian. It is a rare to regular visitor to eastern and western Oregon from late September to late April. The Blue jay prefers open mixed forests or deciduous groves and is often found in orchards and parks and along wooded city streets. Hear the…

The Black oystercatcher is easily recognized with its black plumage, long, strait, laterally compressed, orange-red bill with a yellow tip, orange-red eye ring, yellow iris, and pale pink legs. These birds are restricted to rocky coastal shorelines where they feed in the intertidal zone. They are an uncommon to fairly common resident on rocky shores and sand/gravel beaches along the entire coast. Along the sandy central coast, they are present only as an occasional dispersing or wandering individual, typically on jetties. Black oystercatchers are Oregon Conservation Strategy Species in the Nearshore ecoregion. Hear the call of the Black oystercatcher Photo…

These small, chunky plovers are uncommon to locally abundant migrants statewide, where they are among the most visible and easily identified small shorebirds. The only single-banded plover that occurs in Oregon, they can be remarkably easy to see when they are moving about on mud flats, and remarkably hard to detect when only their unmoving brown backs are visible against the mud. It is an uncommon to locally abundant migrant, with most birds at estuaries and some concentrations in spring at larger lakes of southeast Oregon. In the fall, it's rare in the Cascades; in winter, it's uncommon at larger…

Dashing and darting about, flashing its bright white underparts, the Violet-green Swallow is one of the characteristic birds of summer. Unlike the Tree Swallow it commonly nests in niches and cavities on urban buildings and readily uses nesting boxes in residential areas. Its soft twittery call notes are a familiar pre-dawn sound as they fly about overhead. The Violet-green swallow is a very early spring migrant concentrating about streams and wetlands where emerging insects can be found until warmer weather allows them to move into more upland areas. It is a common to abundant summer resident and breeding species throughout…

Arguably the most widely recognized of Oregon's birds, the American robin is the largest, most abundant, and most widespread thrush in the state. Ranging from sea level to treeline, the robin's loud, musical voice and conspicuous brick-red chest make it unmistakable to even the most casual of observers. The robin thrives in both human-dominated and natural landscapes and is considered to be a habitat generalist throughout its range. Considering the robin's natural history, we know most about its diet, which comprises primarily of soft invertebrates in the spring and summer and fruit in the fall and winter. It is most…
