A grass foraging device for captive chimpanzees (Pan troglodytes)

In the wild, chimpanzees spend most of their time foraging, so any device that stimulates this behaviour in captivity could potentially be effective enrichment. A simple grass foraging device constructed of a polyvinyl chloride (PVC) pipe cut in half lengthwise...

Frozen enrichment for chimpanzees

We gave this enrichment [frozen juice container] to 19 chimpanzees of different ages and found that it took from 24 to 48 minutes for each chimp to consume the frozen treat.
