Indian peacocks were frequently used in European heraldry with the peacocks most often depicted as facing the viewer and with the tails displayed. In this pose, the peacock is referred to as being "in his pride". Peacock tails, in isolation from the rest of the bird, are rare in British heraldry, but are used frequently in German systems. [100]
Leucism (/ ˈ l uː s ɪ z əm,-k ɪ z-/) [2] [3] [4] is a wide variety of conditions that result in partial loss of pigmentation in an animal—causing white, pale, or patchy coloration of the skin, hair, feathers, scales, or cuticles, but not the eyes. [4] It is occasionally spelled leukism.
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
This leucistic Indian peacock, Pavo cristatus, is unlikely to find a mate and reproduce in a natural setting due to its unusual coloration.However, its striking colour is appreciated by humans, and may be included in artificial selective breeding to produce more individuals with the leucistic phenotype.

The peacock tail in flight, the classic example of an ornament assumed to be a Fisherian runaway. Fisherian runaway or runaway selection is a sexual selection mechanism proposed by the mathematical biologist Ronald Fisher in the early 20th century, to account for the evolution of ostentatious male ornamentation by persistent, directional female choice.
