How the bird flies, how the bird flies

Birds can fly around in the air in two ways: flapping wings and gliding.

1. Flap the wings to fly

Wing flapping is a basic way of flying for small birds, and by flapping the wings up and down, the bird can freely control its body to rise or proceed. This type of flight can be divided into two stages: lifting the wings up and flapping the wings down.

When lifted, the wings bend and the feathers spread out to form many gaps, and the air above the wings can flow downwards through the gaps, making it easier for birds to flap their wings.

When the next shot is taken, the wings are straightened and the feathers are brought together to compress the air backwards and downwards. At this point, the air provides an upward lift and a forward thrust trail to the bird, and the combination of the two allows the bird to fly upwards or forwards quickly.

2. Gliding flight

Small birds can also fly in the air by gliding flights. Gliding is when birds use air convection or wind to fly leisurely in the air. This type of flight does not require the flapping of wings, so it is also called "free flight".

Different birds have different gliding effects.

For example, some birds can fly in the air for long periods of time, while others can only glide short distances. Small birds usually glide over long distances with the help of the wind, such as rocs, seagulls, etc. In short, birds can fly around in the air through two ways: flapping wings and gliding, both of which are unique skills that birds have evolved over the course of their evolution.

Analysis of the original hail causes of bird flight:

Having a pair of wings is the first condition for a bird to fly, and scientists believe that the structure of a bird's wings is as complex as the overall function of birds. The feather structure of a bird's wing cleverly uses the principle of aerodynamics to propel the air and use the reaction force to fly forward.

The structure of the feather gap is scientific and reasonable, which can effectively reduce the air resistance encountered during flight, and some can also remove vibration and noise reduction, so that the difference in wings alone has created many excellent or ordinary "pilots". The mystery of the birds' flight depends not only on their wings, but also on their special bones.

Bird bone is an excellent "lightweight material", hollow and lightweight. According to the analysis, bird bones account for only 5-6 of the bird's body weight, while human bones account for 18 of the bird's body weight. Due to the light bones, the wings are very easy to move, and there are many air sacs connected to the lungs in the bird's body, which is very beneficial for reducing its own weight and increasing buoyancy.

Mother Bird finally decided to teach the bird to fly.

She took the bird to a large tree, then taught it how to fly and demonstrated it herself.

The bird looked at his feet and shrank back in fear.

Mother Bird patiently taught him little by little.

The little bird mustered up the courage to spread its tender wings.

Why are you such a bad mother, do you want your child to fall to death? ”

A shrill voice came.

The bird looked down and it turned out to be a mother chicken with a flock of chicks under the tree.

The mother bird said gently: "I am teaching children to learn to fly, which is a necessary survival skill for every bird." ”

I can't fly, I don't live a good life, it doesn't make sense that you have to rely on being able to fly and live in pants? Mother Chicken was puzzled.

Mother Bird choked for a moment.

But I want to see the sea on the other side of the mountain. A childish voice sounded.

It turned out to be a bird talking.

The little bird continued to say to the mother chicken, "I want to learn to fly, not only the sea, but also to see the human city that my father described to me, I have heard that there are many things that are different from Jane, and when I see them, I can tell them to my children." ”

Now it was the turn of the mother chicken to be speechless.

Kiss, you weigh the fiber, and the birds fly freely in the sky. It soared into the sky for a while, as if it wanted to be with the white clouds, to see who could fly high, and then it swooped down, and then flew away into the distance. It does a few lines to show its flying skills, it does as it pleases, and it is unrestrained.

Maybe it got tired of flying, and it stood on the branches, chirping, and began to show off its singing voice again.

Summary. Kiss! Hello, happy to answer for you. Dear, the birds fly around in the air mainly by the action of their wings.

Kiss! Hello, happy to answer for you. Dear, the birds fly around in the air mainly by the action of their wings.

Dear, here is a hint that the birds have a thin layer of feathers on their wings, which can form a thin, tough surface on the wings, creating enough lift to make them fly in the source air. During flight, the bird uses the muscles on its wings to vibrate rapidly to accelerate the air flow, resulting in a larger lift and a greater lift, so that it can stay flying in the air.
