These sounds let group members know that they are among kin and there is no danger. In the case of the appearance of any signs of danger (such as suspicious sounds or movements in a forest), the animal that notices danger first, stops moving, stops producing sounds, remains silent and looks in the direction of the danger sign. Other animals quickly follow suit and very soon all the group is silent and is scanning the environment for possible danger.
