The river was only ankle deep for this family of elephants.   Watching the babies frolic in the water as they plodded across reminded me of the John Wayne movie "Hatari" and the song, "Baby Elephant Walk" by Henry Mancini.  On our side of the river there were giraffes and gemsboks getting their morning drink, and a baboon troop was walking down the dusty road.  Elephants, like beavers and humans, have a great capacity for altering their environment.  They require both a drink of water and a tremendous amount of vegetation each day.  They break down branches and push over trees just to eat the succulent branch tips or to strip off and eat the bark.  Elephant poaching in Kenya was way down in 1993, largely thanks to the hard-nosed policies of Richard Leakey.
