Raisin boards are blocks of wood with holes drilled in them that we put raisins or other dried fruit into and the chimps have to use tools or find other creative ways to get the food out. We have implemented an evening “enhanced enrichment” program, in which we present the chimpanzees with a puzzles or some other type of challenge at the end of the day to help keep them from getting bored. Tonight’s raisin boards had a peanut butter/banana paste in them, which the chimps really loved. Here’s Missy’s strategy.
Whatever works, right?
