A pintail duck swims calmly in the waters of the Merritt Island National Wildlife Refuge, which shares a boundary with the space center. The pintail can be found in marshes, prairie ponds and tundra, and salt marshes in winter. They range from Alaska and Greenland south to Central America and the West Indies. The open waters of the Wildlife Refuge 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. The refuge comprises 92,000 acres, ranging from fresh-water impoundments, salt-water estuaries and brackish marshes to hardwood hammocks and pine flatwoods. The diverse landscape provides habitat for more than 310 species of birds, 25 mammals, 117 fishes, and 65 amphibians and reptiles, including such endangered species as Southern bald eagles, wood storks, Florida scrub jays, Atlantic loggerhead and leatherback turtles, osprey, and nearly 5,000 alligators
