Cover Story: Zoos must promote animals’ welfare. One way to do that is by encouraging cooperative interactions between keepers and zoo animals. Effective communication between them should use channels that are most useful to the animals. We looked at whether captive orangutans understood keepers’ instructions when they employed words only, gazes only, gestures only, or all signal types combined. We found that orangutans only needed gestures to respond to the keepers’ instructions. Why is that the case? We found no indication that gestures providing iconicity or even pointing could help orangutans to acquire associations between a new gesture and referent. Our results suggest that among human communicative signals, captive orangutans would prefer gestures. Why this is the case should be the focus of future research. View this paper
