We included raisin boards in this morning’s enrichment, and Missy demonstrated a new technique for fishing the raisins out (at least one that I haven’t seen before). Rather than trying to pry the raisins out or poke them out the other side, she would insert the chopstick and push it all the way through, like she was sewing with a big needle. It seemed to work well, except for when her tool would get stuck, in which case she would just break it off and start over with a smaller stick.
Raisin logs are a fun treat, especially for Jamie who gets to exercise her tool-using ability. We drill holes in logs and then stuff raisins into the holes so the chimps have to work to get them out. Jamie also gets to exercise her hoarding tendencies – check out the pile that she gathered by her feet.
Chimps are famous for their ability to use tools, but its not just a means to an end for them – most chimps truly enjoy the process.
