"8 a.m. Every morning, keepers conduct a visual assessment of the elephants—from the tip of the trunk to the tail and everything in between. On cue, the elephants will present different body parts so we can observe each individual closely. As part of our daily routine, we use operant conditioning and positive reinforcement to teach the elephants these behaviors. Each elephant has the choice to participate or not. When they participate, we reward them with their favorite foods and say “good job” to affirm that behavior. Some days, an elephant may not feel like participating in training, and that’s ok, too. We want them to have a positive view of their keepers and these training sessions, so we do not force them to do anything they do not want to do. Rewarding good behaviors while respecting their choice to participate has helped us to build trust with the elephants in our care." -Kayleigh Sullivan, animal keeper #WorldElephantDay
