Courtship display is a special, sometimes ritualised, set of behaviours which some animals perform as part of courtship. Courtship behaviours can include special calls, postures, and movements, and may involve special plumage, bright colours or other ornamentation. A good example is the 'dancing' done by male birds of paradise. Such behaviour has multiple purposes, but the first and foremost is to identify the species of the animal performing the display, and hence to prevent biologically wasteful matings between different species. For example, each of the British tit species displays a characteristic that distinguishes them from the others: the great tit swells its chest to show off its black stripe, the crested tit raises its crest, the bearded tit puffs out its black cheeks.

Famous quotes containing the words courtship and/or display:
“Reverence to a woman in courtship is less to be dispensed with, as, generally, there is but little of it shown afterwards.”
—Samuel Richardson (1689–1761)
“We rarely quote nowadays to appeal to authority ... though we quote sometimes to display our sapience and erudition. Some authors we quote against. Some we quote not at all, offering them our scrupulous avoidance, and so make them part of our “white mythology.” Other authors we constantly invoke, chanting their names in cerebral rituals of propitiation or ancestor worship.”
—Ihab Hassan (b. 1925)
