Detailed explanation-1: -Male peacocks, known for their brightly colored jewel-toned feathers, show off their colorful train or tail to attract a female. When it comes to selecting a mate, peahens (female peacocks) decide what is attractive. Peahens often choose males for the quality of their trains.

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: -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-4: -The Indian peacock has iridescent blue and green plumage, mostly metallic blue and green, but the green peacock has green and bronze body feathers. In both species, females are a little smaller than males in terms of weight and wingspan, but males are significantly longer due to the “tail", also known as a “train".

Detailed explanation-5: -However, peacocks use their feathers to attract peahens (female peacocks). The peacocks with the showier feathers are able to attract mates, so they are the ones that have offspring, and pass on the fancy-feather genes to the next generation.
