Cape Romain National Wildlife Reserve, South Carolina

Wide saltwater marshes, barrier islands and tidal rivers of the 64,000 acre wilderness expanse that stretches for 22 miles down the Atlantic coast are a haven for geese, duck and swans flocking there, as well as for the threatened loggerhead turtle. The U.S. Fish and Wildlife Service protects the sanctuary for thousands of other shorebirds that winter over, including the lovely white ibis.
