Rhesus monkeys also use aggression as a punishment. These animals have five distinct calls that they can "decide" to produce upon finding food. Whether they call or not is related to their gender and number of kin: females call more often and females with more kin call more often. However, sometimes when food is found, the individual ("discoverer") does not call to attract its kin and, presumably, to share food. If lower ranked individuals find this discoverer to be in the food drop area of the experiment, they recruit coalition support against this individual by screaming. The formed coalition then chases this individual away. If higher ranked individuals find this discoverer, they either chase the discoverer away or became physically aggressive towards the individual. These results show that aggression as punishment is a way to encourage members to work together and share food when it is found.
