Daphne Sheldrick reports "We were waiting at the mudbath for Malaika and the babies to arrive when we heard a lot of trumpeting in the distance. Suddenly NDUME arrived in a state, looked around hastily, and rushed off again, going through bushes in his haste. We could hear him trumpeting way in the distance, and suddenly the trumpetting stopped. Obviously he had been separated from DIKA because later all three BOYS arrived with two wild friends in tow. DIKA stood in front of us giving the usual "friendly" signal to his wild friends, as though to say "These humans are O.K." When the tractor arrived with water, THE BOYS went over to drink from the bins as they were being filled and the two wild elephants stood at a distance giving the "friendly signal" to the tractor! When an elephant gives the "friendly signal" the trunk is laid over a tusk.
