Why He's Tough: After leaving Syracuse as an All-American in football and lacrosse, Jim Brown went on to produce arguably the greatest rushing career in history. In 118 career games, Brown averaged 104.3 yards per game and 5.2 yards per carry. He never missed a game in his career. (#2)
Possibly the best known of the North American spotted brown thrushes and the only one that commonly nests in parks and gardens, the 8-inch-long wood thrush is noted for its incredibly musical song, a flutelike ee-oh-lay. The wood thrush is known by several other names, including bellbird, in reference to its clarionlike song.
