Chimpanzees have famously been observed using tools in the wild to gather food, often with sticks that are used to fish termites from their mounds. We have an artificial termite mound that provides enrichment for the resident chimps.
Just like human beings think of puzzles and devices that require problem solving, their closest relatives with whom they share 98.7% DNA also enjoy enrichment which gives them positive interactions with their environments and encourages them to be active and explore in ways they naturally would in the wild.
Enrichment occurs when animal keepers introduce new scents, objects or food like honey to our animals in order to stimulate natural behaviors.
