Communication Many species engage in vocalizations that carry specific meaning. Diana monkeys emit predator specific vocalization (one particular to eagles and another particular to leopards). The casqued hornbill has learned the significance of the calls – they respond defensively when the monkey calls indicate an eagle is in the vicinity but they ignore the leopard calls (eagles, but not leopards, prey on the birds).
