Fall through Spring, the Salish Sea is home to murrelets, scoters, buffleheads, goldeneyes, harlequins, mergansers, loons and grebes. Beaches and bay shores harbor dunlins, sandpipers, sanderlings, plovers, killdeers and turnstones. Shallow waters provide habitat to wigeons, mallards, pintails, teals, shovelers, gadwalls and scaups. These birds (and more!) add a potpourri of diversity to the resident oystercatchers, kingfishers, gulls, pigeon guillemots, cormorants, great blue herons, bald eagles, hawks, owls and open field species.
Perhaps most impressive, and awaited of all, are the thousands of snow geese and swans (both trumpeter and tundra) that overwinter in Skagit Valley.
