This highly aquatic snake is found in wet meadows, riparian areas, marshes, and moist forests near rivers, streams, lakes and ponds. It requires streams with thick riparian vegetation for escape and exposed boulders for basking. The Pacific coast aquatic garter snake takes aquatic prey such as small fish and fish eggs, salamanders, tadpoles, frogs, toads, earthworms, and leeches. Photo by Simon Wray, ODFW

Clark's grebe is very similar in plumage, habitat, and behavior to the western grebe. It breeds in inland lakes with emergent vegetation such as cattails and tules. It requires open water for foraging on the surface or diving below in pursuit of fish. It winters both along the seacoast and on major rivers. Like the western grebe, Clark's grebe is a specialist in fish, which make up over 80 percent of its diet. It will also eat other aquatic organisms like crayfish, amphibians, and aquatic insects. Its breeding range in Oregon overlaps that of western grebe, but Clark's is not…

This is a marine gull that breeds on both offshore islands and rocky cliffs along the Oregon Coast. It also uses structures for nesting and, occasionally, will nest on grass-covered headlands. The Western gull's food comes from the marine environment, estuaries, and the immediate shoreline. It eats small fish, clams, mussels, bird eggs, the young of other birds nesting nearby, sea urchins, starfish, squid, crustaceans, marine worms, and carrion. it will scavenge garbage or waste from fishing boats as well. It is present all year along the entire coast of Oregon. Hear the call of the Western gull Photo by…

This gull nests on offshore islands, rocky coastal cliffs, and sometimes in grass on level parts of headlands. It forages in the marine and intertidal environments. Glaucous-winged gulls eat just about any animal material they find. They take small fish, barnacles, molluscs, sea urchins, bird eggs, carrion and animal waste discarded from fishing boats. It is rare but regular along the coast and the Columbia River; local and rare in the Willamette Valley. In can be uncommon midwinter at Sauvie Island. Most Glaucous-winged gulls in Oregon nest in the mouth of the Columbia River. Hear the call of the Glaucous-winged…

This is a small tern most often seen along the coast flying along the beaches or hovering and diving over a school of fish just offshore. Breeding-plumage adults have sharp black caps, reddish bills, and forked tails, and are pale grayish above and white to pale gray below. They are a common to abundant spring and fall transient over the ocean, usually within 15 miles, irregularly along the coast and in the estuaries. Nearshore and inland flocks are often observed resting in compact flocks on nearby shores or on floating objects, or flying about over the water in search of…

A big, well-mannered bird of friendly, even playful disposition, with an abundant curiosity as to human presence and activities within the realm of open ocean over which he presides. Long-winged, to seven feet, and dark sooty-brown; adults have a white rump and feathering, which juveniles lack, around the base of a large bill. Every sighting of these gentle giants gliding up to the boat evokes delight. The black-footed albatross is a regular visitant spring through fall offshore, but is irregular in winter. They glean squid, fish and fish eggs from the ocean surface and also eat galley scraps. Hear the…

The bottlenose dolphin is the most common of the oceanic dolphins and can be found in all tropical and temperate oceans. Flipper was a bottlenose dolphin. Their considerable intelligence and permanently-affixed smile make them a favorite of aquarium and television shows. The U.S. Navy also uses bottlenose dolphins to find mines and booby traps underwater. Oregon is the northern extent of its range on the West Coast. They are most often seen offshore during the summer by tuna and other fishers. They are gray with light gray to white on the undersides. In size they range from six to 13…
