Bright Plumage in Male Birds to Attract Females is Proven

Some scientists are playing with the truth about colorful plumage in male birds. They are claiming that bright colors as well as dull colors in females are to assist in blending into the environment. This is rot. Bright colors always stand out from any background.
Bright plumage male and female birds
Because just under half of bird species have females with brighter plumage than males, this supposedly proves their case. Have they considered that females need to be attractive to males as well? They predict that bright plumage will be lost in evolution. It hasn't lost been so far and there is no support for this claim.

Female humans are different than males and it should stay this way. There is no evolutionary pressure for it not to continue. Birds are no different. The premise "that both natural selection and sexual selection were (are) influential to bird coloration" is not substantiated in their research. This is just an opinion. There is no proof. Indeed, evidence for this view is virtually nonexistent.

Less Atractive Males Make do With Plainer Females

An audience affects the behavior of mating male fish. If a male Atlantic Molly (Poecilia mexicana) is left alone he will try to mate with the healthiest looking female - the best female in his eyes. If there are other males in the vicinity he will not choose this female.

It may be thought that he is giving up. This is not the case. He is thinking strategically. By choosing a less desirable female he leads other males away from the intended target best female. The male hopes to mate with this female later when the other rival males have gone.

Some males are just too ordinary and have to mate with lesser females because other fitter males stop them getting close to "ideal" females. Mating with any female is better than not mating at all.

This behavior could be present in humans. When a group of young men meet with a group of young females the handsomest men can be expected to pair off with the prettiest young ladies. The less attractive have to make do with second best. This means that some of the good genes carried by the plainer individuals can be passed on despite mating between the healthier, fitter thus better looking people being the norm.
