The big move
Wildlife vet Andre Uys peers out at the herd through the doors of the blue and white helicopter as the chopper peels off to the left, its rotors dipping below the tree line.
Beneath us, a herd of elephants is roaming across the plain.
"Tell the vehicles to wait there," the pilot radios to the ground crew on the edge of the flood plain. "Standing by at the junction," they message back.
Uys pulls a dart from a plastic rack; he has to be careful, just one prick from the sharp spike and its powerful cocktail could floor him in minutes.
