Training provides mental and physical stimulation for our eastern black rhino, Boone as well as a way to encourage a positive staff-animal relationship. In this video, we ask Boone to do a few behaviors: target, move-in, sit and lie down. When he lies down, it gives us a chance to look at the bottom of all feet and inspect his footpads. He also enjoys tactile reinforcement and when lying down, keepers can rub his face and scratch his back #WorldRhinoDay | San Francisco Zoo
