Birds are friends of man, and what kind of bird is a good friend of man

I've always loved small animals since I was a child, so I've had many small animals at home. I've had puppies, mice and ......Not only do I like my own animals, but I also like the animals of my neighbors, and I often play with them, and sometimes I can't help but touch them with my hands.

One afternoon, when I came home from school, I heard a sound of chirping as soon as I entered the house. I quickly walked over and saw a small sparrow on the ground. Its small eyes, pointed mouth, round head, gray-brown feathers, and pointed claws are really cute.

Hey, how did it get in? I looked around and saw that it had flown in through a crack window. There is no other place to get in!

Well, I was pleasantly surprised and immediately went to the window and closed it. At that time, I was very careful, afraid that the little sparrow would spread its wings and fly away. To my surprise, the little sparrow only jumped a few times on the ground.

Now, I see that the window is closed, and I think I can catch it. I crept over and saw that the sparrow didn't fly, but just jumped a few times. I immediately threw my hands on the ground, and ah, I caught the sparrow.

I happily picked it up**. That's when I realized that the sparrow had been injured. There was blood on the wings, and there was a small bullet in the wound.

So, I wanted to heal it, to heal it. I performed a minor operation on the little sparrow, helped him remove the bullets from his wings, and gave him medicine and bandaged it. Then, I found a cardboard box.

I put some sponge and straw inside the carton to make a home that is both comfortable and warm. Then, I put the little sparrow in and let it recuperate.

Early the next morning, I got up and ran to the cardboard box. I saw that the little sparrow in the box was dead. I asked my dad sadly

I give it **, why does it still die? The father said, "Don't be sad, son, it's because it's so bad."

Well, animals are our good friends, and I hope that everyone will not hurt them, but protect them and live in harmony with them.

Birds, for humans, are their friends.

1. In the process of foraging, birds can eat a lot of pests, protect crops, forests and plants, and reduce natural disasters caused by pests.

2. The fruit seeds of the birds foraging will fall elsewhere with the locust droppings, so it helps the dispersal, reproduction and growth of plant species.

3. Birds are the main animals that humans appreciate, making our surrounding environment beautiful and colorful. Bird language can regulate the function of the human nervous system and relax people's nervousness. Many birds also accurately predict weather changes.

Fourth, birds inspire human intelligence.

1. For human beings to explore ideals, it provides the principle and blueprint of technical devices or means of transportation. In terms of the structure, function, communication and other aspects of physical technology, scientists often need to consult birds and explore the principle of biomimicry.

2. The eagle strikes the sky, the pigeon flies thousands of miles, and the birds can fly freely in the air. More than 400 years ago, the Italian Leonardo da Vinci designed an ornithopter based on his observation and study of birds, trying to flutter and fly with the movement of his pedals. Later, after many scientists' experiments, people figured out the mechanism of bird fixed-wing gliding, and realized that the wing must be like a bird's wing with a thick leading edge and a thin trailing edge, forming a curved surface to generate lift, coupled with the industry to provide lightweight metal materials and high-power mass wide motive, and finally invented the airplane in 1903, realizing the ideal of thousands of years of human beings eager to fly into the sky.

3. The wings of birds have many special functions and structures, which make them not only good at flying, but also can take off and land vertically, and can fly backwards, or hover in the air. Humans have used this principle to create vertical take-off and landing aircraft with bird flight characteristics.

4. The eagle soaring at an altitude of two or three thousand meters has extremely keen eyes, and it can find rabbits and mice from many relatively moving scenes, and swoop down agilely to capture them in one fell swoop. Eagle Eye is also sensitive to moving targets, quick to adjust, and can accurately identify targets. Modern electron-optical technologies made it possible to work on an Eagle-eye-like system that would help pilots identify ground targets and, at the same time, control missiles.

5. Birds have excellent navigation skills. Migratory birds travel distances ranging from hundreds of kilometres to thousands of kilometres, and they always reach their chosen destinations for generations. Scientists have found that birds have good navigation skills because they have their own special sensory organs, which can sense and analyze the changes in environmental factors in different regions of nature, so as to identify directions and find migration routes.

Some rely on identifying the position of the sun and using the sun as a directional marker; Some rely on identifying the position of the stars and using the stars to navigate; Some rely on sensing the changes in the earth's magnetic field and use geomagnetic navigation; Others use the Earth's gravitational field to navigate. The principle of bird navigation has promoted the development of the aerospace industry.

According to the relationship between birds and modern humans, there are 9 groups of ecological birds, edible birds, hunting birds, service birds, medicinal birds, family birds, feather birds, ornamental birds and beneficial birds.

1.Ecological birds: Bird ecology is related to human ecology, and birds are called ecological birds.

2.Food birds: the economic potential of birds to domesticate poultry, and wild birds with the potential to domesticate poultry.

3.Hunting birds: Strictly speaking, all birds hunted by humans for meat, eggs, or feathers fall under the category of hunting.

However, sometimes people do not hunt their egg-laying birds in order to obtain bird eggs, which should also belong to the category of hunting Qingheng hunting birds. China's stone pheasant, such as partridge, bamboo chicken, golden rooster, wild goose, bean goose, ruddy shelduck, green-winged duck, hairy-legged sandgrouse, bead-necked turtle dove, bone top chicken, etc., are all famous hunting birds. For hunting birds, it is necessary to implement the policy of "protecting, raising and hunting at the same time".

That is, rational hunting, actively carry out the domestication and semi-domestication of wild birds, and protect the female and young birds during the breeding period.

4. Service Birds: Ostriches are the largest birds in the world. The largest ostrich transport station in Mauritania has hundreds of ostriches.

The ostrich has a small three-colored flag tied around its neck for short-distance packers, and a colorful back cushion is laid on its back. The ostrich has a small black flag tied around its neck for short-distance transportation, and a rattan basket is attached to its back, which can hold a lot of goods. Long-distance transportation ostriches, can transport goods, can also carry people, can walk 500 kilometers at a time l Those ostriches are dressed in red and green, and there is a band that blows and blows, and the ostrich team dedicated to picking up and dropping off the bride is naturally more beautiful

Ostriches are even more skilled in shepherding sheep than sheepdogs. A police officer on a farm in South Africa trained a tall rice (8 feet).Weighing 136 kilograms (300 pounds), the great ostrich always holds its neck high and watches everything warily.

Ostriches often run back and forth, driving the stray sheep back to the flock in time. If a wolf or a sheep thief comes, the ostrich can kick them and cut their ribs and cut their belly with their sharp claws. Shepherding sheep for 3 years, shepherding hundreds of sheep for the farm, and never lost a single sheep.

Ostriches can't fly, but they run extremely fast. Athletes rely on their superb riding skills to control the ostrich race, which often reaches speeds of more than 50 kilometers per hour.

5.Medicinal birds (medical birds): Birds whose whole body, internal organs or their metabolites can be used as medicine to treat diseases.

6.Birds: Birds used in scientific research.

7.Feather birds: provide humans with down, decorative feathers, carving feathers and other raw materials. It is used to make various light industrial products, toys and arts and crafts, arrows and feathers are made from the tail feathers and feathers of large eagles, and pheasant tail feathers are used as decorations.

8.Ornamental birds: Birds that have ornamental value are called ornamental birds.

9.Beneficial birds: The vast majority of birds living in nature are natural enemies of agricultural and forestry pests (beasts), and some of them even feed almost exclusively on insects.

They guard forests, orchards, and fields all year round to hunt insects and eliminate pests for farmers. Birds of prey remove rotting flesh and filth and debris, play an important role in protecting agricultural and forestry production, and compete for the natural environment, and also play a great role in promoting the recovery of animal populations.

The small birds that are good friends of humans are swallows, woodpeckers, and sparrows, which are as follows:

1. Swallows: Swallows can fly very high and can help control the population of mosquitoes, flies and other pests, as well as help spread pollen.

2. Woodpecker: Woodpecker is a natural tree cave medicine trader, which can remove rotten wood in the trunk and promote the healthy growth of trees.

This is the fourth volume of the primary Chinese text, and it is recommended to read the original text.

Extended information: Qinghai Lake Bird Island, named after the hundreds of thousands of migratory birds that inhabit the island. Their real names, the small island in the west is called Haixi Mountain, also known as Xiaoxi Mountain, also called Egg Island; The large island to the east is called Haixipi.

The terrain of Haixi Mountain resembles a hump, and the area was originally only 0.11 square kilometers, but as the lake water drops, it expands, and the top of the island is 7.6 meters above the surface of the lake. The island has a large number of birds, about.

Eighty or ninety thousand. Hercypi is the kingdom of cormorant birds, and the cormorant nests that inhabit it are connected one by one, like a bird's castle, so Hercypi is also called Cormorant Island.

Because birds are part of nature, humans are also part of nature, so people and birds are friends.
