Selfish or altruistic? An analysis of alarm call function in wild capuchin monkeys, Cebus apella nigritus [PDF]

, 2008
Alarm calls facilitate some antipredatory benefits of group living but may endanger the caller by attracting the predator's attention. A number of hypotheses invoking kin selection and individual selection have been proposed to explain how such behaviour
