KENNEDY SPACE CENTER, FLA. -- A great blue heron watches warily near a canal on Kennedy Space Center. These herons inhabit lakes, ponds, rivers and marshes. They range throughout the United States. Fish and frogs are its principal food but will also feed on small mammals, reptiles and, occasionally, birds. 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
