primates and syntax

By modifying a call sequence or the order of calls within a sequence, the messages are changed, and can relay precise information about the nature of the danger (a falling tree, a predator), the type of predator (eagle, leopard), how the predator was detected (acoustically, visually) but also about social events unrelated to predation (gathering before the group moves to another site, an encounter with another group of the same species at territory boundaries...)
