The canals that crisscross England have long supported rich natural habitats. Along the Macclesfield Canal, in Central England, diving rodents called water voles hunt for prey below the water's surface. Kingfishers alight on the trees that line the banks, intently eying the flowing water, then swooping down on unsuspecting fish. In spring and summer, flowers burst forth in waves of color. This program depicts the 4 seasons along England's canals, where people and nature live in splendid harmony.
