The Long-tailed Duck (Clangula hyemalis) is a distinctive sea duck that breeds on high arctic coasts and tundra of both the eastern and western hemispheres. In North America, it winters south along the Pacific coast to California and along the Atlantic coast to northern Florida. In the interior of the continent, it winters regularly in large numbers on the Great Lakes (AOU 1998, Robertson and Savard 2002). The species occurs in migration or winter in all states of the continental U.S., including south to the Gulf of Mexico from Florida to Texas, and across the interior of the border states of Texas, New Mexico, Arizona, and California, where rare but annual in occurrence (AOU 1998, https://eBird.org).
