Display (zoology)

Many male birds have brightly coloured plumage for display. This feather is from a male Indian peafowl Pavo cristatus.
Sexual display by a Megaselia female.

Display behaviour is a set of ritualized behaviours that enable an animal to communicate to other animals (typically of the same species) about specific stimuli.[1] Such ritualized behaviours can be visual, but many animals depend on a mixture of visual, audio, tactical and chemical signals.[1] Evolution has tailored these stereotyped behaviours to allow animals to communicate both conspecifically and interspecifically which allows for a broader connection in different niches in an ecosystem. It is connected to sexual selection and survival of the species in various ways. Typically, display behaviour is used for courtship between two animals and to signal to the female that a viable male is ready to mate.[2] In other instances, species may make territorial displays, in order to preserve a foraging or hunting territory for its family or group. A third form is exhibited by tournament species in which males will fight in order to gain the 'right' to breed. Animals from a broad range of evolutionary hierarchies avail of display behaviours - from invertebrates such as the simple jumping spider[1] to the more complex vertebrates like the harbour seal.[3]
