When the elephant keepers at the Smithsonian's National Zoo hear the
sound of a harmonica, it's not the radio they've left on. Instead, it's
the Zoo's 36-year-old Asian elephant, Shanthi, who, unsolicited, has a
propensity for coming up with her own ditties using whatever instruments
the keepers have provided. These include harmonicas, horns and other
noisemakers. The Zoo has captured some of Shanthi's most recent
capriccios on this video.
