KENNEDY SPACE CENTER, FLA. -- Possibly a willet or a sandpiper in winter plumage, this bird nearly blends into the rocky background of the river bank on Kennedy Space Center. KSC shares a boundary with the Merritt Island Wildlife Nature Refuge. The refuge is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles. In addition, the Refuge supports 19 endangered or threatened wildlife species on Federal or State lists, more than any other single refuge in the U.S. Photo credit: NASA/Dimitri Gerondidakis KSC-07pd0868
