The bird known for its colorful feathers and tail is the peacock, specifically the male peafowl, which displays an iridescent array of blues and greens in its plumage. The male's vibrant tail feathers, known as a train, can span over six feet in length and are adorned with eye-like patterns that serve both aesthetic and mating purposes. During courtship, the male fans out its train in a magnificent display to attract females. Peacocks are native to South Asia but have been introduced to other regions, and they are often associated with beauty and grace in various cultures.
