Feather, a seemingly unremarkable natural thing, has infinite charm and mystery. They are ornaments for birds, flying tools, warm barriers, courtship tokens and unique symbols endowed by nature. In this article, we will discuss the types and functions of feathers and their position in human culture. Let's learn about the types of feathers. Feathers are mainly divided into two categories: flying feathers and down.
Flight feathers are the main tool for birds to fly. They are long and hard and closely arranged. The growth and wear of flight feathers are closely related to the flight ability of birds. Feather is the main material for birds to keep warm. They are short and soft, asymmetrical in shape and loosely arranged. The growth and replacement of down feathers are closely related to the living environment of birds. There are also some special feathers, such as the bright tail feathers of male birds and the beautiful eye-shaped stripes shown in "Proud", which have unique symbolic significance in the animal kingdom.
Feathers have many functions. First of all, feathers are the basis of birds' flight. When birds flap their wings, the flight feathers generate lift and make them soar in the air. Secondly, feathers are a barrier for birds to keep warm. Feathers can effectively keep the temperature in birds and make them live in a cold environment. In addition, feathers are an important tool for birds to courtship. Many males attract females by showing off gorgeous feathers, so as to achieve the purpose of reproducing.
Besides, feathers also play an important role in music, dance and sports. In orchestral instruments, feathers are used to make various playing parts, such as flute and suona. In dance, dancers often use feathers as props to add beauty and mystery to the performance. In sports, badminton is a popular sport, and its competition rules and skills are closely related to the characteristics of feathers.
