The Indian peacock feathers are used in many rituals and ornamentation and its motifs are widespread in architecture, coinage, textiles and modern items of art and utility. [31] Indian peacock motifs are widely used even today such as in the logos of the NBC television network and the Sri Lankan Airlines. [101] [102]
Plumage (from Latin pluma 'feather') is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs.
Feather variations. Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates [1] [2] and an example of a complex evolutionary novelty. [3]

The peacock, on the right, is courting the peahen, on the left. The plumage dimorphism of the peacock and peahen of the species within the genus Pavo is a prime example of the ornamentation paradox that has long puzzled evolutionary biologists; Darwin wrote in 1860: The sight of a feather in a peacock’s tail, whenever I gaze at it, makes me ...
A peacock's tail almost certainly reduces survival of the peacock as they reduce maneuverability, power of flight, and make the bird more conspicuous to predators. [1] Ornaments, therefore, have a great effect on the fitness of the animals that carry them, but the benefits of having an ornament must outweigh the costs for them to be passed on.
The peacock-pheasants are a bird genus, Polyplectron, of the family Phasianidae, consisting of eight species. They are colored inconspicuously, relying on heavily on crypsis to avoid detection. When threatened, peacock-pheasants will alter their shapes using specialised plumage that when expanded reveals numerous iridescent orbs.
