White pelicans swim in a lake north of Kennedy Space Center. In the distance, at right, is a great blue heron. White pelicans winter from Florida and southern California south to Panama. Great blue herons range across the breadth of the United States, as well as north to Alaska and Canada and south to Mexico and the West Indies. The Center shares a boundary north, south and west with the 92,000-acre Merritt Island National Wildlife Refuge, which is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. The marshes and open water of the refuge also provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds.
