I was scheduled to train on interacting with the chimpanzees. Lisa (my trainer) told me that Tatu would really like some lipstick. I went to the bin and picked out several colors (including black, Tatu’s favorite) and some flavored chapsticks. We don’t give the lipstick to the chimpanzees; they stick their lips out through the caging and we apply it for them. We went into the human cage (a place where we do interactions with the chimpanzees. It is designed to make it look like the humans, not the chimpanzees, are in the small cage) to offer them to her. I lined them up on the floor so she could see what options I had for her. I signed, WHICH YOU WANT? Tatu was eating a piece of lime so I waited for her to finish. All of a sudden, Tatu got up and ran into the other room. She turned in the doorway and looked back at me. I had no idea what she was doing and I think she could see that on my face. She came charging back to the human cage with her hair pilo erect and a hose in her hand. She looked like she was displaying threat behaviors so I backed up in case she was going to try to hit me with the hose. When she got to where we were, she shoved the hose through the caging like I thought she was going to, but she wasn’t directing it at me. She went directly for the lipstick and knocked the black one into the red zone (the area around the enclosures where the chimpanzees can reach out and where we are never allowed to reach into…). The black lipstick was hers! Now whenever I apply lipstick for Tatu she positions me next to a hose so she is always ready (or maybe I am paranoid).
