Display is a form of
animal behaviour, linked to
sexual selection and survival of the species in various ways. One example of display used by some species can be found in the form of
courtship, with the male usually having a striking feature that is distinguished by colour, shape or size, used to attract a female. In other instances, species may exhibit territorial display behaviour, 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.
