The bird featured in the video, and the one that most people think of when they picture a peacock, is an Indian blue peafowl (Pavo cristatus) although they are commonly called simply Indian ...
Evolutionary game theory encompasses Darwinian evolution, including competition (the game), natural selection (replicator dynamics), and heredity. Evolutionary game theory has contributed to the understanding of group selection, sexual selection, altruism, parental care, co-evolution, and ecological dynamics. Many counter-intuitive situations ...
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]

[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.
In the 1920s and ’30s, people put classified ads in the Miami Herald selling peafowl. One ad described the bird as having “wonderful plumage” that would “ornament any home or division.”
This is particularly true for smaller animals like cats and dogs if they happen to get too close to a peacock nest. Male peacocks can get aggressive during mating season and will be more ...
Biologists from Darwin onwards [23] have puzzled over how evolution produces species whose adult members look extraordinarily alike, and distinctively different from the members of other species. Lions and leopards are, for instance, both large carnivores that inhabit the same general environment, and hunt much the same prey, but look quite ...
Male peacock spider, Maratus volans, courtship display In some species, males will perform ritualized movements to attract females. The male six-plumed bird-of-paradise (Parotia lawesii) exemplifies male courtship display with its ritualized "ballerina dance" and unique occipital and breast feathers that serve to stimulate the female visual system.
