A group of peacocks is called a ‘muster.’
This term is not widely known outside of ornithological circles, where precise terminology is often used to describe groups of animals. The term ‘muster’ can refer specifically to peacocks and is sometimes extended to include peahens, which are the female counterparts of peacocks. Interestingly, the male peacock is famous for its extravagant and colorful tail feathers, which are displayed during courtship rituals. While the collective term ‘muster’ may not roll off the tongue for everyone, it reflects the unique beauty and distinctiveness of these magnificent birds.
