Dunlin
Calidris alpina
Vast differences are obvious in winter and breeding plumages, as the Dunlin sports a ruddy brown back, white underparts, and black belly patch in the spring, but has a very nondescript grayish plumage in the winter. Dunlins generally tolerate colder weather better than many other shorebirds, migrating southward relatively late in the fall and often overwintering as far north as New England or the coast of Alaska.
Habitat: Flooded fields, lake margins, mudflats during migration. Breeds on mixed tundra/wetland in Canada and Alaska. Found in coastal habitats in the winter and in migration.
Diet: Primarily insects and insect larvae on migration through the state. Also small mollusks and crustaceans, small fish, and some plant material.
Breeding: Non-breeder in South Dakota.
Song: Raspy zheeep.
Migrations: Summers in northern Canada and Alaska. Winters along North American coastlines.
Similar Species: Sanderling
Status: Numbers have seemingly declined since the 1970's.
