Have you ever seen a peacock in a zoo open screen? Tourists shake their gorgeous flower umbrellas to the peacock, or the girls wear beautiful flower skirts, the peacock is not happy, it twists its neck, "uproar" to open its colorful feathers, as if to compare beauty with people. Why exactly does the peacock open the screen, do you know the reason for it?
In the 19th century, there was a famous Biologist in England named Darwin, who put forward the idea that in the bird world, polygamy is practiced, and the more wives each male has, the more children it has, so any feature that can make the male attract the female is conducive to breeding offspring, and the female seems to be more fond of the colorful and exuberant husband, so the colorful characteristics of the male are thus strengthened from generation to generation. The German zoologist Grymecker agreed with Darwin that when he studied the habits of peacocks, he found that when a male peacock approached the tree or cliff where the female peacock lived, he always tilted his body back a little, and then unfolded his colorful feathers so that the female peacocks in the heights could see their beautiful color screen, as if to say: Look how godly I am, come and play with me. The female peacocks, who are proud to be like princesses, are not very pretty, they only have gray-brown feathers. Darwin's doctrine was once convincing, but recently there has been a diametrically opposed view – the "less likely to catch" hypothesis – that has also piqued interest.
The "not easy to catch" hypothesis is made by British zoologists Peck and Pike. They believe that all birds that are good at spotting predators, or who are lively and clever, who are good at escaping predators, have bright feathers, and they seem to have no fear, showing that they are extraordinary. Birds that are not good at finding and escaping predators must be good at hiding themselves, so they do not have bright colors. They also explained that in birds that practice polygamy, the males are more colorful because they are tasked with hatching eggs and appear less lively than the males.
The two zoologists believe that the lively and clever, brightly colored male birds mostly "collectively propose" to the female in the open area, and they are so bold because their beautiful feathers can scare off ill-intentioned catchers, such as the gorgeous spots on the tail of the peacock after opening the screen, are not like the eyes of the big eyes? This can confuse other animals. And those birds that play love songs in the deep grass are generally gray-feathered.
Zoologists in our country also believe that tourists' bright costumes and loud laughter will stimulate peacocks and arouse their vigilance or vigilance. At this time, the peacock opens the screen, which is a demonstration and defensive action.
Both hypotheses sound very plausible. Who is right? Maybe one day, you'll be able to solve the mystery.
