The Piping Plover 
The piping plover is a small, stocky, sandy-colored bird resembling a sandpiper. When still, the piping plover blends into the pale background of open, sandy habitat on outer beaches where it feeds and nests. It became a protected species under the Endangered Species Act on January 10, 1986. Along the Atlantic Coast it is designated as threatened, which means that the population would continue to decline if not protected.
