We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment, randomly imposing two treatments: customised one-way vision screens on the exhibit viewing windows to reduce visual contact with visitors; and unmodified viewing windows that allow full visual contact with visitors. We sampled capuchin behaviour including intra-group aggression and other social interactions, vigilance and abnormal behaviours. To provide a measure of physiological stress, we also analysed ca..
