Contact calls are seemingly haphazard sounds made by many social animals (such as a chicken's cluck). Contact calls are very different from many other types of calls (for example, alarm calls), as contact calls are not a specific signal, designed to communicate some specific information. It is rather a mixture of various sounds, accompanying the group's everyday business (for example, foraging). Contact calls are used to maintain audio contact with the members of the group.
