Why Is It Called Peacock Island?

The name "Peacock Island" is a fairly recent nickname that became popular due to a simple visual observation. Here is the explanation for its name:
The British Connection
The name came from British colonial officers during the British Raj. When they first looked at the Brahmaputra River, they saw that the island's shape, with its lush green trees and its particular height, resembled the spread feathers of a peacock when seen from a distance or from the higher riverbanks.
Visual Symbolism
- The Shape. From a specific angle, the narrow part of the island looks like a bird's neck. The wider, forested area resembles the vibrant, rounded tail.
- The Colours. The thick, dark green plants against the blue waters of the Brahmaputra reminded early explorers of the shiny colours seen on a peacock's feathers.
Contrast with the Local Name
While the world knows it as Peacock Island, locals still mainly refer to it as Umananda Island. In the Assamese language and Hindu tradition, the names reflect the island's spiritual roots:
- Umananda: Derived from the words 'Uma', which means 'Goddess Parvati', and 'Ananda', which means 'Happiness/Joy'.
- Bhasmachal: It is also referred to as "Hill of Ashes", which refers to the geological or mythological nature of the rocky outcrop.
