This nocturnal species is seldom-seen, sometimes known by its call on summer evenings or as a blur fluttering quickly up from secondary roads. Cryptic mottled, brownish-gray plumage helps it to blend in with dry, barren ground and to conceal it from predators. Common poorwills are smaller and shorter-tailed than other nightjars; when observed in the air, their flight resembles a moth or bat, noiseless and low over the ground. Locally common east of the Cascades, they are rare farther west in Josephine County. They are commonly found along the Snake, Wenaha and lower Grande Ronde rivers. Hear the call of
The Common nighthawk is a migrant to Oregon with one of the longest migration distances of any North American bird. It is also one of the last to arrive in Oregon. Long, slender wings are marked by a white patch on the "hand" visible in flight from great distances. When perched on the ground, the cryptic brown, gray, and black mottling makes the bird almost invisible. This bird breeds and migrates at all elevations through the state. Its nesting habitat is characterized by open landscapes with little ground cover and is most abundant in sagebrush and rocky scablands and rimrock
Insects swept up in a rising air mass are favorite prey of this species nicknamed the "cloud swift." It prefers to nest near or even behind the curtain of a waterfall. This dark swift glides for long distances, often very high in the sky, with its wings held somewhat downward. It is larger and darker than the more common Vaux's swift, and has a slightly forked tail. The Black swift is a rare to uncommon spring and fall transient and summer visitant throughout the state. It's an Oregon Conservation Strategy Species in the West Cascades ecoregion. Hear the call of
With long, pointed wings, nighthawks can sometimes be seen during the day catching insects while in flight although most are active at night. Nighthawks roost by scraping the ground or roost on low branches. Nestlings can fly at 10 days old. Swifts nest on vertical walls, such as chimneys or old smoke stacks, hollow trees or rock crevices. It's fun to watch them at dusk in summer, circling their nesting site. These birds are never seen perched, but only in flight.
The Tufted puffin is the most recognized seabird in Oregon. It is common to abundant at breeding rocks but rare to uncommon elsewhere owing to its pelagic feeding habits. It is easily identified in the breeding season by the colorful laterally compressed bill, a distinct white face with long cream colored facial plumes, black body, and red feet. In winter it moves offshore and loses most of its colorful plumage and bill plates. It nests along the entire Oregon coast where soil-covered islands are present. It also nests on headlands such as Cape Mears, Cape Lookout, Cape Foulweather, and Yaquina
Rhinoceros auklet are one of the rarer breeding alcids in Oregon. Adults are easily recognized during the breeding season by the vertical "horn" at the base of the upper mandible. Birds in breeding plumage have brownish gray backs, a gray-brown chest, and a dirty white belly. Two distinct plumes are present on the head, one above and one below the eye. The bill is orange. In non-breeding plumage the horn is greatly reduced, the plumes absent or reduced, and the bill duller. It nests in small numbers in Oregon with Goat and Hunter Islands having the largest concentrations of breeding
During the breeding season Pigeon guillemots are easily seen flying low over the water along rocky coastlines or in estuaries. They have striking red feet, legs, and mouth linings and their large white wing patches contrast markedly with the rest of their black plumage. When standing on land they have a distinctive upright posture and often emit a high-pitched squeal. In the non breeding season they move offshore and look entirely different when their black plumage becomes mottled with white. The Pigeon guillemot occurs during the breeding season all along the Oregon coast wherever offshore islands or rocky cliffs are
These small, fast flying seabirds are unique among alcids in North America in their use of coastal coniferous forests, primarily old-growth trees, as nesting habitat. Their solitary nests are usually concealed within the forest canopy, and breeding birds are cryptic and primarily crepuscular at nest sites. Because of their secretive behavior and elusive nests, Marbled murrelets were considered the "enigma of the Pacific" and were one of the last ornithological mysteries in North America, as the first nest was not discovered until 1974. Distribution at inland nesting sites is fragmented, as birds occur only in areas where suitable habitat remains
Horned puffins have an unmistakable black and white plumage and a large, distinct, yellow and orange bill during the breeding season. They are rare in Oregon, and most commonly encountered dead on the beach in winter or spring, or sighted more than 50 miles offshore in spring. Individual birds, or possibly pairs, occasionally stay in Oregon for the breeding season and are seen attending colonies with Tufted puffins, but there are no records of breeding in Oregon.

The most common seabirds breeding in Oregon, Common murres are easily recognized by their distinct black and white breeding plumage and their upright stance at colonies. Wing-beats are rapid and like all alcids they can fly underwater. They are often seen over the ocean in long lines of 10-40 or more birds. They nest on rocky islands and cliffs in colonies of tens or hundreds of thousands of birds packed together almost shoulder to shoulder. Major nesting concentrations in Oregon are on the south and north coasts reflecting the availability of suitable nesting habitat. Hear the call of the Common
Cassin's auklet uses a few offshore lands for breeding in Oregon. It forages in the marine environment and nests in a chamber under rocks or digs its own burrow, two to six feet long, in the soil. This species spends its day at sea and only comes to the burrow at night, perhaps to reduce discovery by predacious Western gulls. Although few Cassin's auklets nest in Oregon, nesting sites are found along the entire coast where offshore rocks provide appropriate habitat. During the non-breeding season this is the most abundant alcid seen at sea in Oregon. They are present offshore
Murres, auklets and puffins are all sea birds that only come ashore to nest. The most unique is the Marbled murrelet which flies inland - sometimes great distances - to nest in coastal coniferous forests.
The mottled petrel breeds in New Zealand and nearby islands, and ranges throughout much of the Pacific Ocean, mostly far from land. It is a common May to October visitant in the northern and eastern North Pacific, with non-breeding birds occurring during the winter months. Photo by Dominique, Flickr
This large loon breeds in the Arctic tundra from Northwestern Russia across Siberia and Alaska through Canada to Hudson Bay. It winters in North America along the coast of South Alaska and British Columbia, and regularly in small numbers south to Baja, California. The majority of Oregon records are of transient birds found between early November and early June. Hear the call of the yellow-billed loon Photo by Mark Peck, Flickr
The largest of Oregon's grebes, these have a long white neck, black cap, bright red iris, long strait bill, dark back, bright white breast, and they appear tailless. While excellent divers, they are unable to walk on land because their body weight is forward of their legs. Differences in appearance between western and Clark's grebes are subtle. In the western grebe, the black cap typically extends down to the eye whereas white facial plumage extends slightly above the eye on the Clark's grebe, but this is not always diagnostic in winter. The western grebe is a common breeder in eastern
This seabird, the most abundant in Oregon, has recently suffered severe declines or significant population shift in the eastern North Pacific. Similar in shape to thin, long-winged gulls, sooty shearwaters are dark sooty gray with limited amounts of white on the underwing coverts. They glide on wind currents along wave troughs on stiff wings. Gregarious, they form huge loose flocks in migration, often passing for hours within site of land-based observers. In Oregon, it is an abundant summer visitor and transient offshore on the inner shelf and is most numerous three to six miles offshore. Hear the call of the
These very abundant seabirds are uncommon off Oregon in winter. Their arrival coincides with some of the Pacific Northwest's stormiest weather. Complicating detection difficulties is their identification; they look very much like the abundant sooty shearwaters - all dark, but slightly smaller with shorter bills and tails. Studied on their Tasmanian breeding grounds continuously for over 45 years, once they leave for the open ocean little is known about them. Popularly know as "muttonbirds," they have been harvested as food for centuries on their southern seas breeding islands. Even today, up to 300,000 chicks are harvested in Tasmania each year
A small loon holding its slender head erect and narrow, upswept bill upward is most always a red-throated. A quick flyer, it can be identified by rapid deep wing-beats, humpbacked body with head and neck extending below the body, and wings appearing far to the rear due to the usual invisibility of the small feet. Often feeding near the surf, it may be spotted by beachcombing humans. It can take flight from a small water area, and can also, if pressed, take flight from land. It is an abundant Oregon nearshore transient from fall through spring. Hear the call of
This medium-sized, shy grebe has bright white cheeks that contrast sharply against a dark crown and rust red neck during the breeding season. An aquatic bird, it breeds in lakes and ponds, usually in forested areas. In Oregon, it is found in waters with hardstem bulrush intermixed with open water over five feet deep. Five to 20 birds at Rocky Point in the Upper Klamath Lake National Wildlife Reserve form the only consistent breeding population in Oregon. The red-necked grebe reaches its greatest numbers during winter along the coast. The red-necked grebe is an Oregon Conservation Strategy Species in the
The world population of this species, which probably does not exceed 25,000 pairs, is quite low for a seabird. Nevertheless, these are the common light-bellied shearwaters off Oregon in summer. They are larger, bulkier, and fly more deliberately than the usually much more abundant sooty shearwaters with which they associate. They are uniform gray-brown above; the underparts are white; the vent and underwings variably smudged with dusky. The pinkish bill is dark-tipped and the feet are pink. It is a common summer visitor and very common fall transient offshore on shallow shelf waters. It is usually seen seaward, approximately five
