display behaviour


display behaviour

Ritualized activity by which an animal conveys specific information. The best-known displays are visual, but others rely on sound, smell, or touch. Agonistic (aggressive) displays make it unnecessary to chase intruders from a territory or for animals to injure each other in competition for mates. One type of defensive display deceives predators or lures them away from vulnerable young. See also birdsong; courtship behaviour.
