Stereotyped behaviour, involved in communication, that is largely acquired genetically. It may be associated with courtship, in which physical characteristics (plumage, antlers, etc.) are exhibited by an animal as a means of attracting and securing the co-operation of a sexual partner, deimatic, a threat (e.g. in a bird establishing a territory), or cryptic (i.e. making the animal more difficult to see).
