How does choosing a male with a bright, full tail increase a peahen’s chance of producing healthy peachicks? 2 See answers 311650 311650 Answer: Typically, if a peacock has a bright tail with many feathers and eyespots, a female will choose him. These tail features indicate that the peacock may be healthier than other males and, therefore ...
When the peahen observes a peacock spreading his feathers, she chooses whether he's a suitable mate for her. Generally, the more eyespots and the bigger the tail, the better his chances are for procuring one or many mates. Particularly "attractive" males may collect several loyal mates, all of which find the qualities of his tail irresistable.
“It is an awful stretcher to believe that a peacock’s tail was thus formed, but believing it, I believe in the same principle somewhat modified applied to man,” Darwin wrote in 1864.
The basis for this statement is rooted in the idea that the peacock's tail 1, because of its extravagance, is a costly feature that will negatively impact male fitness and consequently its display is an "honest signal" to females regarding the male's genetic superiority. The first problem is whether this is actually "costly".
Researchers find that males can respond quicker than females to sexual selection, resulting in glitzier garbs like the male peacock's tail feather, which outshows any drab peahen.
A male peacock's tail feathers can be up to 6 feet long, far longer than his 2-foot long body. The feathers are iridescent blue, green and purple, with distinctive eye shapes near the tips. The eye shape can be considered another adaptive trait. When threatened, the male peacock raises and spreads his tail feathers.
Selection that occurs when individuals at one end of the curve have higher fitness than indiviuals in the middle or other end. Stabilizing selection When individuals near the center of the curve have higher fitness that individuals at either end.

Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger ...
Then, the male will turn and display his feathers about 45° to the right of the sun’s azimuth which allows the sunlight to accentuate the iridescence of his train. If the female chooses to interact with the male, he will then turn to face her and shiver his train so as to begin the mating process. Evolution and sexual selection
A high-quality tail is costly to have because it takes much metabolic energy and esources to grow and maintain such a resplendent ornament, which is useless and even detrimental in other aspects of a peacock’s life; a high-quality tail is an honest signal of good genes because only those peacocks who are in good health and who have the traits required to survive and acquire abundant supplies of food can afford to waste their energy and resources to grow and maintain this showy and ...
The peacock survives by bluffing would-be predators into looking for easier prey. By puffing up his chest and fanning his feathers, the male peacock struts through life with little to show for his efforts but possibly a harem of loose, distracted, and easily entertained lady peacocks; who hardly resemble ladies.
Selection that occurs when individuals at one end of the curve have higher fitness than indiviuals in the middle or other end. Stabilizing selection When individuals near the center of the curve have higher fitness that individuals at either end.
Make your own food. If you cannot find bird game food or prefer not to use it, you make your own food for your peacock. To do this, feed your peacocks a mixture of chicken pellets and mixed grains (barley, wheat, rice). Corn feed is also acceptable. You might want to add some dog food (for larger dogs) into the mix.
Male peacocks fan their colourful rear feathers and shake them, but somehow keep their plumes' iridescent circles, or eyespots, nearly still, like a fixed stare. Key points Peacock tail feathers ...
When the train is erect the peacock often rattles the feathers together to produce a curious rustling noise. The volume of this noise may well be related to the number
Although the male train and its direct display towards females seem necessary for successful reproduction, we conclude that peahens in this population are likely to exercise active choice based on ...
But bigger is only better up to a point. If peacock trains become too big or too colorful over time, they may no longer confer a selective advantage. Exaggerated trains might attract a new kind of ...
Genes involved in early developmental pathways including TGF-β, BMP, and Wnt signaling, which have been shown to be involved in feather patterning, bone morphogenesis, and skeletal muscle development, revealed signs of adaptive evolution and provided useful clues on the phenotypes of peacock.
