The lady and the peacock pdf

Male peafowl are known for their piercing the lady and the peacock pdf and their extravagant plumage. The Indian peacock has iridescent blue and green plumage, mostly metallic blue and green.

But the green peacock has green and bronze body feathers. Both species are as big as the male but lack the train and the head ornament. These feathers are marked with eyespots, best seen when a peacock fans his tail. Both sexes of all species have a crest atop the head.

The Indian peahen has a mixture of dull grey, brown, and green in her plumage. The female also displays her plumage to ward off female competition or signal danger to her young. The green peafowl differs from the Indian peafowl in that the male has green and gold plumage and black wings with a sheen of blue. Unlike the Indian peafowl, the green peahen is similar to the male, only having shorter upper tail coverts, a more coppery neck, and overall less iridescence.

The Congo peacock male does not display his covert feathers, but uses his actual tail feathers during courtship displays. These feathers are much shorter than those of the Indian and green species, and the ocelli are much less pronounced. Chicks of both sexes in all the species are cryptically coloured. They vary between yellow and tawny, usually with patches of darker brown or light tan and “dirty white” ivory. Occasionally, peafowl appear with white plumage.

This can result in the complete lack of coloration of their plumage, while preserving normal eye colour. Leucistic peachicks are born yellow and become fully white as they mature. Slight changes to the spacing of these barbules result in different colours. Such structural coloration causes the iridescence of the peacock’s hues. Interference effects depend on light angle rather than actual pigments. Sexual selection is the ability of male and female organisms to exert selective forces on each other with regard to mating activity. The strongest driver of sexual selection is gamete size.
