Seabirds spend most of their lives in the open ocean and have special adaptations to survive this cold and wet environment. Thick, waterproof feathers keep them warm; a special gland near their eye removes excess salt from their bodies; sharp, pointed beaks catch and hold slippery fish and other aquatic quarry; strong, pointed wings help some seabirds "fly" underwater; and webbed feet propel them efficiently towards their prey.
Below are some notable species found at Oregon Islands NWR and other refuges in the Pacific Northwest. The Pacific Northwest Seabird Brochure is another valuable resource.
The Common Murre is Oregon’s most abundant nesting seabird—more than 700,000 flock to our rocky coasts in spring to breed. They raise their chicks on rocks and cliff ledges in colonies of tens of thousands of birds. Colony Rock boasts the largest number of Common Murre; view them from Yaquina Head Outstanding Natural Area in the summer. You can also see them from Coquille Point in Bandon and Heceta Head and Cape Meares State Scenic Viewpoints.
The Tufted Puffin easily wins the title of "most-wanted bird to see" among nature enthusiasts visiting the coast of Oregon. Known to some as "parrots of the sea", these charismatic birds return annually to a few nesting islands on the coast. Viewing locations include Haystack Rock at Cannon Beach, Face Rock in Bandon and Goat Island at Harris Beach State Park.

A chunky pigeon-like build gives the Pigeon Guillemot its name, though it's more closely related to puffins. During the breeding season, bright red legs and feet along with white wing patches make these seabirds easy to identify. Guillemots make nests in the crevices of rocks, where both parents help raise a brood of three chicks. Viewing locations include Haystack Rock at Cannon Beach, Yaquina Head Outstanding Natural Area and Seal Rock State Park.
Often found poking around rocky shorelines in the intertidal zone, Black Oystercatchers are a chatty, vivacious presence. Despite its name, this vermillion-beaked shorebird catches not oysters but mainly mussels and limpets for food. Black Oystercatchers nest just above the high-tide mark, on beaches and slopes in areas where prey is abundant. Outside of the breeding season, look for flocks of these unmistakable birds foraging on our coast.
California Brown Pelicans are huge and unmistakable visitors to the Oregon coast, stopping by on their migration to and from winter breeding grounds in southern California and Mexico. Since breeding occurs from January to May, many pelicans spend the summer months "wintering" here afterward. Watch their spectacular sidelong dives into the water for prey, using their famed three-gallon throat pouches as scoops. Only one other pelican (the closely related Peruvian species) feeds via plunge-diving—the rest of the world's eight pelican species employ less daring tactics. Look for low-flying squadrons of Brown Pelicans gliding in formation over the Pacific, wingtips nearly brushing, undulating gracefully above the waves.
Brandt's Cormorants are one of three cormorant species found regularly on the Oregon coast. Distinguished by a comparatively short tail and blue throat in breeding season, they nest colonially on rocks and headlands and are the most common of the cormorants on the Oregon coast in the summer. Like all cormorants, their feathers are not waterproof—this decreases their buoyancy, making it easier for them to dive for fish. Brandt's Cormorants can be seen from April to August at Yaquina Head Outstanding Natural Area, Heceta Head State Scenic Viewpoint, and Coquille Point.
The most abundant cormorant species throughout Oregon. Found in both fresh- and saltwater habitats, Double-crested Cormorants get their name from the jaunty white plumes sported by breeding adults. Most of the year, these birds can be identified by their yellowish cheeks and lores—the area between the bill and eye. Watch for them perched on rocks and dock pilings, wings outspread to dry in the sun.
Our smallest cormorant, known by its thin neck and bill, comparatively long tail, and iridescent green-black plumage. Breeding adults have red lores and white patches near the rump. Pelagic means "living in open oceans or seas", and these cormorants stay true to form, almost never venturing inland to freshwater. Look for their nesting colonies at Coquille Point, Haystack Rock at Cannon Beach, and Yaquina Head Outstanding Natural Area.
In an area teeming with gulls, the pink-legged, slaty-backed Western Gull is coastal Oregon's most abundant. Proper identification takes uncommon patience and skill, as well as a fondness for minutiae. Confusing matters further, Western Gulls hybridize easily with several other gull species—the intergrades can be all but inscrutable. Western Gulls are opportunistic and rapacious feeders, often preying on the young of other nesting seabirds.
Leach's Storm-petrel is a roughly robin-sized, narrow-winged pelagic bird, rarely seen near shore outside of breeding season. Fifteen offshore rocks within Oregon Islands NWR are breeding sites for this colonial, burrow-nesting species. The smallest pelagic breeding seabird in Oregon, Leach's Storm-petrels will fly more than 100 miles offshore to feed on shrimp, fish and squid. They return at night to regurgitate food for their chicks, using a well-developed sense of smell to locate individual burrows amidst the colony.
These are one of Oregon's rarer breeding alcids—the family of superficially duck-like oceanic birds that come to land only to nest, typically in colonies. During the breeding season these seabirds grow a vertical horn-like structure structure
Something temporarily or permanently constructed, built, or placed; and constructed of natural or manufactured parts including, but not limited to, a building, shed, cabin, porch, bridge, walkway, stair steps, sign, landing, platform, dock, rack, fence, telecommunication device, antennae, fish cleaning table, satellite dish/mount, or well head.
Learn more about structure at the base of the upper mandible, hence the name. Closely related to the puffin, the Rhinoceros Auklet likewise feeds on sand lance, herring, anchovies, and smelt. They feed offshore during the day and return to the colonies at night, to avoid predation by gulls. Rhinocerous Auklets can be seen breeding in the Sea Lion Caves south of Cape Perpetua.
Like the Rhinoceros Auklet and Tufted Puffin, Cassin's Auklets dig burrows for their nests, typically two to six feet long. This small, chunky, blue-legged auklet is the only known Northern Hemisphere seabird that can raise two broods in a season. They spend the winter at open sea and are the most common alcid seen off the Oregon coast. Despite this, not many Cassin's Auklets breed here—there are less than a dozen sites and fewer than 1,000 nesting birds.
Unique among alcids, Marbled Murrelets are solitary nesters in an unusual habitat: coastal old growth coniferous forest. Nests are made in trees up to 250 feet high, in groves up to thirty miles inland. They dine on typical alcid fare, though: small fish and krill. It was not until 1974 that the first Marbled Murrelet nest was discovered, and as of the late 1980's, only ten nests had ever been seen worldwide. At sea, Marbled Murrelets can be found during breeding season at Boiler Bay in Depoe Bay, Yaquina Head Outstanding Natural Area, and Cape Perpetua Scenic Area.
