Writing an essay: What are the benefits of being a bird?

1. Write an essay to introduce the benefits of birds to people

My favorite animals since I was a child are birds, because they gave me dreams, and I dreamed that I could be like Like a little bird, it can fly freely in the blue sky.

"Spring sleeps without dawn, and I can hear birds singing everywhere", "Two orioles sing in the green willows, and a row of egrets ascend to the blue sky." In the past, I only knew that the birdsong was clear and sweet. After learning more knowledge Only then did I realize that bird singing, like music, is a kind of information that can regulate the function of the human nervous system, relax people's tension, and thus make people feel relaxed. Some bird songs also play a role in disease prevention and fitness. Therefore, concentrating on listening to the birdsong can rest the tired brain, dispel physical fatigue, forget mental pain, and increase mental happiness.

Birds are also of great help to our human production and life. For example: swallows can capture many pine caterpillars; a pair of woodpeckers can eat more than 1,500 pests a day, helping us protect forestry resources; owls patrol at night and can capture many voles, protecting the safety of the countryside and worthy of being called "pastoral guards." ! Even the feces excreted by birds can be used as fertilizer for trees!

Some birds can bring us visual enjoyment, the first of which is the peacock. When the peacock opens its tail, it is very attractive and beautiful! Some birds have been trained to perform shows, such as parrots learning words and orioles recognizing words. It seems that the IQ of birds is not low! In ancient times, flying pigeons also carried messages. Lu Ban, the ancestor of carpenters, once made a "wooden bird" to fly into the sky, which was the first shadow of modern aircraft. Through the study of birds, we humans have discovered many patterns, such as electronic eagle eyes, navigation and other technologies, which use the principles of bionics to benefit mankind. It seems that birds are not only friends of humans, but also teachers of us humans!

Students, please tell me, birds have so many benefits to us humans, shouldn’t we protect them and become good friends with them?

So how do we become good friends with them? The answer is very simple, that is: first, protect them and not hunt them indiscriminately; second, protect the environment in which they live and give birds a safe and happy home. 2. The benefits of writing about birds in essays

Today I found a very strange bird. It was jumping around on the side of the road. I tried to get closer to it, but it was still jumping around, as if it wanted to fly but couldn't. I held it gently in my hands, and then I discovered that its wings were stained with water, so no wonder it couldn't fly. This is the first time I have seen a bird so close. It has gray feathers and a small tuft of yellow feathers on the top of its head. Its pointed mouth opens back and forth, as if it is talking to me: "Hello, thank you, When my feathers are dry, I can go home." I seemed to understand what it said. After a while, with the help of Father Sun, the wet feathers were dried, and I couldn't help but feel happy for it. Happy because he can finally go home!

Hello, thank you! When my feathers are dry, I can go home! 3. What are the benefits of birds?

Broadly speaking, birds are an important part of nature. Various birds play an irreplaceable role in the harmony and prosperity of nature. For example: some birds can eat insects, which is beneficial to plant growth; some birds eat carrion, which is beneficial to environmental hygiene; some birds pollinate flowers, which is beneficial to plant breeding; some birds prey on other species to inhibit their over-breeding, resulting in out of control. etc. In a world without birds, there is no telling what kind of catastrophic events would happen.

In a narrow sense, someone likes to raise birds. Birds are to him what music is to people who love music, food is to people who love food, and cars are to people who love cars. They are his favorite things. Of course, raising birds cannot interfere with other people's normal lives. Bird keepers should be treated with the necessary respect as long as they do not interfere with the normal lives of others. 4. What kind of bird has that benefit?

1. The body length of the bee-sucking bird native to Cuba is only 5.6 centimeters, of which the beak and tail account for about half. It weighs only about 2 grams. It is about the same size as a bee. This kind of hummingbird is the smallest bird in the world, and its eggs are also the smallest bird eggs in the world. They are not much bigger than a period, and are not as thick as a bumblebee. The egg weighs 0.2 grams, which is about the same as a pea.

Its beak is a thin needle and its tongue is a slender thread; its eyes are like two shining black spots; the feathers on its wings are very thin and seem to be transparent; Its legs are short and small, making it difficult for people to notice; it rarely uses its feet, stopping only to spend the night; it flies continuously, very fast, and makes a buzzing sound. The flapping of its wings was very fast, so when it stayed in the air, it not only remained unchanged in shape, but also seemed motionless, hovering like a helicopter. It stayed motionless for a moment in front of a flower, and then It flew towards another flower like an arrow. It used its slender tongue to penetrate into their arms and suck their nectar, as if this was the only use of its tongue.

2. A moa appeared after the extinction of the dinosaurs. It dominated the earth for millions of years and is the largest bird known to date. It filled the top of the food chain after the extinction of the dinosaurs and before the emergence of large mammals. It is a world where birds dominate, a world where birds eat beasts. The largest bird today is the flightless ostrich. The body of the ostrich is worth dozens of ordinary birds. The appearance of the ostrich eggs alone is worth about 13 eggs, and the weight is worth 26 to 30 eggs. . 3. Whooper swans are migratory birds. They inhabit lakes and swamps. In winter, they migrate in groups to the south in search of food. The flying swans have long straight necks, slightly raised, and elegant wings. They fly regularly every year. Flying over Mount Everest at an altitude of 9144 meters, it is the highest flying bird in the world.

The highest flying speed is 17,000 meters. 4. The fastest flying bird: the sharp-tailed swift usually flies at a speed of 170 kilometers/hour, and can reach a maximum speed of 352.5 kilometers/hour. It is called the fastest flying bird. Fast bird. The fastest bird: ostrich, 72 kilometers/hour.

The fastest swimming bird in other worlds: Gentoo Penguin, 27.4 kilometers/hour. The smallest bird and the smallest egg: Many people know that hummingbirds are the smallest birds in the world. In fact, this statement is not very accurate, because there are about 315 species of hummingbirds in the world, distributed from Alaska in North America to South America. The Straits of Magellan in America and the many islands in between.

Their body shapes are also very different. The largest giant hummingbird is 21.5 centimeters long. Of course, it cannot be said to be the smallest bird in the world. The body length of the bee-sucking bird native to Cuba is only 5.6 centimeters, of which the beak and tail account for about half, and the weight is only about 2 grams. It is about the same size as a bee. This type of hummingbird is the smallest bird in the world. Its eggs It is also the smallest bird egg in the world, not much bigger than a period.

Most of the hummingbird feathers are very bright and shine with a metallic luster. Their flying skills are superb, they can fly backwards, take off and land vertically, and their wings vibrate very quickly, up to 50 to 70 times per second, so they have "magical birds", "comets", "forest goddesses" and "corollas", etc. call.

In recent years, many places in our country have claimed to have discovered hummingbirds, but these are actually misinformation. The largest bird: The largest living bird in the world is the African ostrich that lives in Africa and Arabia. It is 2 to 3 meters tall and weighs about 56 kilograms. The heaviest can reach 75 kilograms.

But it can't fly. Its eggs weigh about 1.5 kilograms and are 17.8 centimeters long, which is approximately equal to the total weight of 30-40 eggs. They are the largest bird eggs today.

The bird with the widest wingspan: Wandering Albatross, 3.63 meters. The largest flying bird: The Collie, which lives in southeastern Africa, has a wing length of 2.56 meters and a weight of about 18 kilograms. It is the heaviest flying bird in the world.

The heaviest flying bird: the great bustard, the male weighs 18 kilograms. The smallest raptor: the Borneo Falcon, with a body length of 150 cm and a weight of 35 grams.

Bird with the most feathers: swan, more than 25,000. The bird with the fewest feathers: the hummingbird, with less than 1,000 feathers.

The bird with the longest feathers: the cuckoo, whose tail feathers are more than twice its body length. The longest-lived bird: There are many long-lived birds among birds. For example, the average lifespan of large seabird albatrosses is 50 to 60 years, and large parrots can live to about 100 years.

There is an Amazon parrot named "Jamie" in Liverpool, England. He was born on December 3, 1870 and died on November 5, 1975 at the age of 104. Is he worthy of being called a bird? "Old birthday star".

The longest-lived ringed seabird: the King Albatross, over 60 years old.

The longest lived caged bird: Sunflower Cockatoo, more than 80 years old. The fastest flying bird: The sharp-tailed swift usually flies at a speed of 170 kilometers/hour, and can reach a maximum speed of 352.5 kilometers/hour. It is called the fastest flying bird.

The fastest sprinting bird: the peregrine falcon, which can reach 180 kilometers per hour when diving to catch prey. The fastest bird in horizontal flight: the European eider, 76 kilometers/hour.

The slowest flying bird: Little Woodcock, 8 kilometers/hour. The bird with the highest wingbeat frequency: Horned Hummingbird, 90 times/second.

The bird with the slowest wing beat: the great vulture, which can glide for hours without flapping its wings. The bird with the longest flight time in one flight: the North American golden plover, flying for 35 hours at a speed of 90 kilometers per hour, crossing more than 2,000 kilometers of sea.

The highest-flying birds: Whooper swans and alpine vultures are the highest-flying birds. They can fly over the roof of the world - Mount Everest, with flying heights of more than 9,000 meters, otherwise they may crash on the steep slopes. died on the ice cliff. The furthest flying bird: The arctic tern is the furthest flying bird.

It is a medium-sized bird that is used to living during the day, so it is called a "day bird". When the Antarctic night falls, they fly to the distant North Pole. Since the day and night at the North Pole and South Pole are exactly opposite, it is daytime at the North Pole.

Every year in June, they "give birth to children" in the Arctic region. In August, they lead their "children" to migrate south. The flight route runs through the earth, arriving near the Antarctic in December, and they stay there until March of the following year. At the beginning of the month, we headed north again. Arctic terns travel between the two poles every year, flying a distance of more than 40,000 kilometers.

Because it always lives in places where the sun never sets, people also call it the "day bird." The most ferocious bird: the Andean condor, which lives among the cliffs of the Andes Mountains in South America, can reach a length of 1.2 meters and a wingspan of up to 3 meters.

It has a strong and hooked "iron mouth" and sharp claws, which are designed to eat live. 5. Composition What are the benefits of woodpeckers?

Woodpeckers Woodpeckers have a hard and long beak and have yellow and red feathers.

Although her eyes are small, she can see very clearly. Her tongue can extend very long, making it easy to catch bugs.

But if you want to get close to her, it is not that easy. When we want to observe her carefully, she will be very alert. Before we get close, she will fly away, flying very fast.

The woodpecker is a famous forest doctor who helps big trees catch bugs. Woodpeckers specialize in eating pests, such as longhorn beetles, gigantic beetles, hyaline moths, worms and other pests. She can eat about 1,500 worms a day.

When catching insects, she first pecks a small hole in the tree with her sharp mouth, then stretches her long tongue into the hole, catches the insects and eats them deliciously. In addition to real-life woodpeckers, there are also movies and cartoon images about woodpeckers in animation.

The reason why we need to protect birds, especially beneficial birds like woodpeckers, is precisely because they can help big trees catch pests, protect our forests, and prevent lush forests from turning into a giant Desert and lack of water resources. Besides, birds are also one of our human friends.

We must protect birds, build beautiful homes, build happy and interesting homes, and make our lives rich and colorful. 6. What benefits do birds have to humans?

Bionics: Birds have superb flying skills. Of course, modern aircraft far surpass birds in many aspects of performance, but in terms of energy saving and dexterity, It pales in comparison. For example, a bird continuously flies over the ocean for more than 4,000 kilometers and loses 0.06 kilograms in weight. The small hummingbird can not only take off and land vertically, but also adopt an upright posture when sucking nectar. It can move forward and backward freely in the air and is extremely flexible. The research and utilization of these special functions will further improve the performance of the aircraft.

For example, wild ducks can fly leisurely at an altitude of 9,500 meters, but it is already difficult for people to breathe when they reach 4,500 meters. Studying why birds' cerebral blood vessels remain open under conditions of thin air is of great significance to humans living normally and extending their lives in an environment with insufficient oxygen supply.

Pigeons have made great contributions to bionics. There is a small and sensitive special structure on its legs that can sense earthquakes. People have imitated a new seismograph based on its principles to make earthquake predictions more accurate. Its eyes have special recognition capabilities because there are 6 types of ganglion cells with specialized functions in its retina: leaf brightness detector, ordinary edge detector, convex edge detector, direction detector, and vertical edge detector , horizontal detector, an electronic model of a pigeon eye made by imitating the cell structure of its retina. Although the structure is not as complex and complete as it is, it has broad application in the field of being installed on warning radars and used in electronic computers to process relevant data. prospect.

Seawater accounts for 97% of the total water on Earth. However, artificial desalination devices for seawater currently have large equipment, complex structures, and high energy consumption. However, seabirds such as seagulls and albatrosses can excrete the salt in the seawater they drink through a salt gland near their eyes. Once the simulation of this function is completed, the prospects for human use of the ocean will be even broader.

In addition, people are developing the Hawkeye system missile based on the structure of the Hawkeye. This missile can automatically find and identify the target and track the attack when it flies over the target.

The economic value of birds: The economic value of birds is very wide. Its uses can be divided into six types.

Poultry. Chickens, ducks, geese, pigeons, quail, etc. mainly provide sources of protein to humans. Poultry is domesticated from pheasants. For example, the ancestor of domestic chicken is jungle fowl, the ancestor of domestic duck is mallard duck, and the ancestor of domestic goose is wild goose. Therefore, wild birds can be used to continuously improve poultry varieties, because pheasants have the characteristics of large size, fast growth, and strong disease resistance, and are a very rich gene pool. Furthermore, domesticating pheasants can expand the variety of poultry. For example, people are now starting to raise swans, bustards, black-bone pheasants, brown-eared pheasants, etc., which may become new varieties of poultry in the future. Therefore, attention should be paid to protecting pheasants.

Hunting fowl. For example, the meat of wild ducks and chickens is edible, and their feathers can be used as feather fans, headdresses, down jackets, down quilts, etc. As long as the relationship between protection and utilization is properly handled, they can become a renewable and inexhaustible resource. Important resources.

Manure poultry. Habitats and migration destinations where birds are concentrated are often the main producers of phosphate fertilizers. For example, the dung left by boobies in the Paracel Islands is accumulated several meters thick.

Medicinal birds. The ones we are more familiar with include bird's nest and silky chicken, as well as white chicken, clove chicken, etc.

Ornamental birds. Like thrush, lark, parrot, mandarin duck, peacock, etc.

Draft birds. Cormorants, sparrowhawks, goshawks, etc. are good assistants for people in fishing and hunting activities.

The scientific value of birds: In fact, human aviation technology does not surpass birds in all aspects. Bird wings can perform quite complex movements. In particular, each move of the fan can continuously generate a kind of aerodynamic force and decompose it into lift and thrust, making it fly freely. Birds can also temporarily fold their wings and glide while flying to reduce physical exertion. People admire the many advantages of flapping flight and are stepping up efforts to imitate and develop "ornithopters" that flap their wings.

In addition, the unique physiological structures and functions of birds provide bionic science research topics for the innovation of mechanical systems, instruments and equipment, building structures and technological processes. In particular, the sensitive and precise orientation, navigation, detection, control and regulation, information processing and biomechanical functions of birds have led people into new scientific fields. For example, the "Pigeon Eye Radar System" manufactured using information bionics.

The ecological value of birds: One owl can kill 1,000 voles in one summer, which is equivalent to protecting a ton of food. A thousand purple-winged starlings roosting in a colony can destroy twenty tons of locusts during the breeding period. A swallow can eat 500,000 to 1 million mosquitoes, flies and aphids in a summer. A single woodpecker can eat 500,000 insect pests living in tree bark in a year. Many birds, such as gray magpies and cuckoos, are insectivores. The role played by various birds in nature in safeguarding human economic interests and maintaining human health is inestimable. In the past, people thought that pesticides could replace everything, so they used various chemical pesticides indiscriminately, resulting in pollution of the environment. From this, people realized the huge role of biological control, especially birds, in natural ecosystems.
