Peacock feathers are commonly referred to as ‘tail feathers’ or ‘train feathers’. The specific name for the ornamental feathers of a peacock, particularly the beautiful, colorful ones that are displayed during courtship, is ‘iridescent plumage’. These feathers are part of the male peacock’s tail, or train, which can be fanned out to showcase their striking colors and patterns.
The vibrant colors of peacock feathers are due to microscopic structures that reflect light, creating the stunning blue and green hues that are so iconic. These feathers serve not only as a display for attracting mates but also play a role in establishing dominance among males.
