(02/26/1999) -- A white pelican stretches its eight-foot wing span as it prepares for flight. The black wing feathers, hidden when folded, appear as shadows against the dappled waters of the Merritt Island National Wildlife Refuge. The habitat of white pelicans are marshy lakes along the Pacific and Texas coasts, wintering chiefly in coastal lagoons such as this one. They often capture fish cooperatively, forming a long line, beating their wings and driving the prey into shallow water. The 92,000-acre refuge, which shares a boundary with Kennedy Space Center, 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
