Why do peacocks fan their feathers?

Peacocks fan their feathers during courtship displays to attract mates. The iridescent colours and intricate patterns on their tail feathers showcase their health and genetic quality. By shaking their tail, they create a shimmering effect that enhances their visual appeal. Peahens choose mates based on the size and symmetry of the tail, as these traits indicate strong genes. While the large tail can make peacocks more conspicuous to predators, it plays a crucial role in reproduction.
