She will spin, roll around on the ground, clap and put enrichment toys on her head. . . . 🧠 As part of the Zoo’s positive reinforcement training program, Calaya voluntarily participates in her own healthcare by presenting parts of her body to keepers and receiving vaccines on cue. Recently, she and primate keeper Carolina Powell started working on a new behavior called “innovate”—a fun cue that gives Calaya the opportunity to be creative with the behavior she wants to demonstrate. Powell invites Calaya to create any behavior she thinks of, as long as she doesn’t repeat it. If she chooses to participate, Powell rewards her with her favorite foods: apples, strawberries, kiwi, mangoes or oranges. . . . 👅 Once she has gone through her normal repertoire of husbandry behaviors, that’s when things get interesting. Occasionally, she comes up with behaviors that are completely new—like thrusting out her bottom lip. Now, Powell has been able to put even more behaviors on cue—and Calaya came up with them herself! . . . #NatZooZen #BringTheZooToYou #ClosedButStillCaring #GorillaStory」7月2日 2時44分
