Detailed explanation-1: -Peacocks rattle or shake their feathers about 25 times per second, creating a rattling sound and an iridescent visual display to attract peahens’ attention.

Detailed explanation-2: -They not only fan out those spectacular tail feathers-called a train-to tempt pea hens, but they also shake them in a behavior called train rattling.

Detailed explanation-3: -The most common mating ritual of the peacock is the displaying of his train. Males spread their tails in a fan shape and strut back and forth while shaking their feathers to produce a rattling noise. This gets the peahen’s attention, and then it’s up to her to pick her favorite male.

Detailed explanation-4: -In Indonesia it is known as the peafowl dance (Merak dance or Tari Merak) and originated in West Java. It is performed by female dancers inspired by the movements of a peacock and its feathers blended with the classical movements of Sundanese dance.

Detailed explanation-5: -Both peacock and peahen have the avian reproductive organ known as a cloaca, which transfers sperm in between partners. The peafowl align their cloacas and the male’s sperm is transferred to the female, where it travels up the uterus to fertilize her egg through a series of muscular spasms.
