A Great Blue Heron cruises the sky near the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. They range throughout the U.S., inhabiting lakes, ponds, rivers and marshes. Their principal food is fish or frogs but may feed on small mammals, reptiles and occasionally birds. The center shares a boundary with the Merritt Island Wildlife Nature Refuge, which is a habitat for more than 310 species of birds, 25 mammals, 117 fishes and 65 amphibians and reptiles.
