Detailed explanation-1: -Courtship behavior can include things like food delivery, dance moves (displays), and mutual preening. In many cases, the most extravagant courtship displays belong to the species where males contribute little else to the relationship-think strutting grouse or dancing birds-of-paradise.

Detailed explanation-2: -A male peafowl (peacock) spreads its feathers to intimidate predators, communicate vibrationally to other peafowl and to attract a mate during mating season.

Detailed explanation-3: -When peacocks are ready to mate, they fan out their iridescent tail feathers (known as trains), before rushing at females, shaking those feathers to catch their attention.

Detailed explanation-4: -To court potential mates, a peacock needs to rattle and shiver these train feathers in a certain way, producing a display of flickering feathers and distinctive noises. It has been known that this courtship dance signals the fitness of the males, as the extravagant display requires energy and muscular power to perform.
