The world's birds are wearing a cloak of feathers, but males and females of the coat is quite different: most of the colorful male, colorful, female's are stereotyped, dull.
Take chicken for example. Cock body tall, bright red comb, golden neck feathers, colorful tail feathers, just like the colorful grade silk; and hen feather color is dark, tall short, tail hard and dull.
Gorgeous peacock feathers precious, unique, known as the "angel feathers"; female peacock is short but bleak, shame. Colorful plumage of male birds, the sun, shines with metallic luster; and female, if not identified according to its mouth, may be mistaken for the other birds do. Why males than females beautiful? Because birds, mostly adhere to the "polygamy" system, the male wearing a colorful feathers, you can show off to the female, courtship, and win more spouses. Once mating is completed, it will fly the nest, find a new love. Since there is no fixed nest, the male predator attacks were less likely. In the "monogamy" system of birds, nesting, incubation and brood of responsibility also falls on most of the female body, male, at best, only a supporting role. Even in love with his male partner of hornbills, the female hornbill never stay in the nest during incubation, but running around foraging to feed their families. It was colorful feathers, and feeding on fruit-ridden environment is very coordinated. Female long incubation in the nest, dark body color with the Bird's Nest and the surrounding environment are very similar, so that predators can not easily be found.
In the bird kingdom, there is no exception? Acacia is a bird, "the couple" shared incubation, alternating between them to sit nest, which is almost the same plumage color also. Most special to snipe a few color. Female wearing a "five Technicolor Dreamcoat" and shiny, the male was bleak. The reason, Painted Snipe is one of "polyandry" system. After mating females lay eggs away to leave the nest, find another partner. Male is responsible for nesting, incubation and brooding, too busy.
From this, the bird's feather color, and courtship, breeding, incubation and brood are closely related, this is the result of long-term adaptation to the environment. |
