CAPE CANAVERAL, Fla. - A belted kingfisher perches on a shrub branch in an area of NASA's Kennedy Space Center in Florida. It is one of 310 species of birds that inhabit the National Merritt Island Wildlife Refuge, which shares a boundary with Kennedy. 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.
