They love oranges.
This was at a tourist attraction near the Addo Elephant Reserve, although not affiliated with the sanctuary. These elephants roam free on the property most of the time, except when they are rounded up 3-4 times a day to carry foreigners like us around, very similar to trail rides on horses. We were told that as adolescents they were relocated to this park from a refuge in Zimbabwe to alleviate overcrowding. The guides who controlled and steered the elephants were all Zimbabwean, too. Riding one is a crazy experience because they're so impossibly big, agile, and smart.
