The peacock is renowned for its majestic tail feathers, known as a "train." Male peafowls, or peacocks, boast vibrant plumage featuring iridescent blue, green, and gold hues. During mating season, males spread their elaborate tail feathers to attract females, showcasing their brilliant coloration and eye-catching patterns called "ocelli." This display serves not only as a courtship technique but also as a demonstration of fitness and vitality, as a larger and more colorful tail often indicates a healthier peacock. The sight of a peacock with its feathers fully fanned is considered one of nature's most striking spectacles, reflecting the bird's beauty and grace.
