These mudflats are an accident of engineering. The North Jetty built at the entrance to Galveston Bay around the turn of the twentieth century interrupted the sand moving along the coast, and sediment piled up behind it into a broad, shallow flat that did not exist before. It is now one of the most important shorebird sites in North America, regularly holding tens of thousands of birds — avocets, willets, black skimmers and red knots among them — feeding on invertebrates in water a few inches deep.
