It s been rare to see swallows in these years, where have they gone?

I remember when I was a child, swallows and sparrows and other birds are common animals in the countryside, and many of us also take swallow nesting as a symbol of mascot, believing that it can bring luck and wealth, but now with the development of social life, there are fewer and fewer houses in the countryside, and we also find it difficult to see the trace of swallows anymore, so as a bird that has been with people's lives since ancient times, it is rare to see swallows over the years, and they have gone to **?

In the past, every household in the countryside lived in a house made of bricks and tiles, and the rural architecture may not be so exquisite, as long as it is practical to shelter from the wind and rain, and will not pursue much beauty, so the beams of the house often become a place for swallows to perch. But now, with the change of social life, many people will pursue aesthetics in addition to the practicality of the house, so many people have made suspended ceilings in their housesThere is not enough space to makeSwallows come in and build nestsWith the change of living environment, swallows rarely come to the house to build nests.

In the past, there were insects and mosquitoes in the countryside, and there was a lot of food that these swallows could hunt, but with the change of the living environment, every household has become clean, and even in summer, they will pay attention to indoor hygiene, so there are fewer and fewer insects such as flies and mosquitoes. And the flying insects in the field are not enough for swallows to hunt, soBecause of the lack of foodIn recent years, the number of swallows has also decreased significantly.

Nowadays, many people pay attention to the cleanliness of their home hygiene environment, if the swallow comes to build a nest, then it will inevitably leave a large pile of feces, which used to be muddy soil, but now it is all cementIt will inevitably look discordantSo people will artificially destroy the swallow nest, prevent them from coming to their homes to build nests, and dirty the environment of their homes, and human factors are also a reason for the decline of swallows.

Because the living environment of humans has changed, there is no space for swallows to nest, and food has decreased, the number of swallows has plummeted, and most of the rest choose to nest in trees.

When I went to the countryside, I could see a lot of swallows in the bungalows, and many swallows were very fond of building nests on the roofs of the bungalows in the countryside.

I went to the south for the winter, and I will return to the north in the spring, and the ecological environment has become worse, and the swallows in high-rise houses cannot build nests.

The swallow is a very spiritual little animal, and from winter to spring year after year, it always follows a fixed path through the beautiful mountains and forests, and happily returns to the warm nest to have children. The morning in the countryside is quiet and deep, and I am always awakened by the swallows under the eaves, chirping and whispering, so the kindness begins with my day's journey. A few years ago, when the house was built in the autumn, the swallow's small house was demolished, and I was constantly uneasy and silently prayed, hoping that the good neighbors would come to build a nest again regardless of the previous suspicions.

First, it's definitely the climate. The swallow is a hard-working species, a resident bird that flies to the warmer south every year during the colder months. Nowadays, the climate is extreme, and in the process of migration, a lot is lost.

Swallows are mainly insects and do not eat berries and debris like migratory birds, so the narrowness of the food chain also affects the population and quantity.

Second, swallows nest in the leeward **, often on the edge of sandy cliffs, and under the eaves of other people's houses, and even through the open window, fly directly into the house to build a nest. The alterations of modern farmhouses have made it difficult for swallows to find a place to live in modern houses without eaves. So we rarely see swallows flying around us these days.

Thirdly, swallows like to be warm and moist, which is determined by food. If the ecological zone is well restored, there will be more swallows, but unfortunately we can't see it.

Swallows are birds that humans are not many willing to harm. Its anthropomorphism is a portrayal of its lifelong toil. Let us be filled with gratitude and warmth.

At the beginning of spring they finally came back, they could not find the nest they seemed very irritable, up and down whirling and chirping, their voices were sad and heart-wrenching, I heard the old generation say that swallows are the most nostalgic animals, and really two days later they flew away and never flew back. Nowadays, the countryside is engaged in urbanization, and a few bird's nests have been destroyed while demolishing the old houses, and the days when those people and swallows are neighbors under the same roof are really hard to rest assured, and wish them to settle happily in the unknown**, which may also be the fundamental reason for the decline of swallows year by year!

Because the natural environment of the city is not suitable for swallows to survive, and there is less food to eat, the number will decrease. They have been forced to fly farther to the outskirts or settle in the wild, where the environment is more suitable for their survival.

Mainly because there are more and more high-rise buildings, the habitat of swallows has been decreasing, and swallows are unable to nest, so there are fewer of them. Some of the swallows died, and some went to the wild.

The swallow is a migratory bird, and now it is winter, and the swallow will go south to spend the winter, and when the weather warms up in the spring, the swallow will return to the north.

Anyone who cares will find that swallows have become very rare now, and many swallows can be found flying back from the south when spring arrives before, but now this scene is rare, because of global warming, swallows go to more comfortable places.

The swallows are all in the countryside, and there are basically no in the city now.

The fact that swallows are no longer visible in the countryside is due to changes in the nesting environment. Swallows build their nests in the house, in the living room. In this environment, swallows not only do not disturb others, but also can get along harmoniously with others.

With the earth-shaking changes in architecture in rural areas, the demand for red brick and tiled houses will be greater. This kind of house small swallows.

There is no way to build a nest because the material is relatively smooth. The swallow nest is mainly bonded with mud, but the sealing of the brick is not so strong. There is no passage for swallows to enter and exit, so there will be fewer and fewer swallows in the countryside. <>

Swallows are very cute, and they may not be seen or affected by food. Swallows are good animals and their main food is to eat insects. Swallows do not forage on the ground like other insectivorous birds, but they do choose to forage when flying.

Flocks of swallows will choose to fly low to hunt, and this is also the time when the storm is coming. There are a lot of insects in the summer, but they are mainly flies.

and mosquitoes. The food that swallows eat is mainly flying insects, and without these foods, they will naturally disappear in the countryside. <>

Many rural people always feel that swallows are very dirty, and they always make their yards full of feces. After this behavior, people in the countryside will choose to destroy the swallow's nest. If the swallows don't have a nest, they don't have a place to live.

Getting rid of the nest is equivalent to taking the life of the little swallow, and in order to protect himself, he can only choose to leave far away. There are various shapes of nests, some like spoons and some like pots. <>

In general, swallows are much better than other birds, and the biggest feature of swallows is their yellow feathers. This swallow is known as the golden-rumped swallow.

And I especially like to throw feces. Golden-rumped swallows are a very dominant species, not only with beautiful feathers, but also very powerful. Swallows are very good animals, and you must learn to protect them.

The little swallow flies south, he actually belongs to his own nest, and he can return to his nest, so many times it belongs to a quieter place.

Now there are fewer and fewer people in the countryside, and most of the people have come to the city, so Xiaoyanzi also followed the people to the city.

Mainly with the improvement of human living standards, many places in the countryside have built cement and steel houses, and the little swallow generally chooses to build under the wooden house, the little swallow is a very intelligent animal, now many people in the countryside have moved to the big city, there are fewer people in the countryside, so the little swallow is not willing to come to live.

Spring flowers and swallows return, this is a portrayal of Northern Spring, and it is also a childhood memory.

First, with the development of society, earth-shaking changes have taken place in rural hometowns. The clear sign is that every family is moving into a new house, and the old house is gone. Due to the change in the building, the living environment of the swallow has also changed.

Today's rural dwellings are fashionable, convenient, beautiful and warm. The houses are all built tightly, and the swallows basically have no living space. In the wild of the countryside, there used to be a wide variety of insects and birds.

Grasshoppers, grasshoppers, crickets, praying mantis stomp their feet in the fields. Regardless of which jump, the flowers will open and attract many butterflies. The pond is overgrown with lotus leaves.

There are often a few dragonflies on the young tips of the newly grown lotus leaves. Speaking of which, there used to be a lot of dragonflies in the countryside, especially after the rain, the door of the farmhouse or some ponds and swamps would be densely covered with dragonflies. Although it cannot be said to be overwhelming, the number is indeed very large.

There will be a lot of bats at night. In the afterglow of the setting sun, they begin to forage for food at night. These scenes, which used to be seen often in the countryside, are now gone.

No, many, many species have become rare, and some have not even been seen by many children.

Second, with the development of economy and society, the natural environment has also occurred, environmental pollution, ecological deterioration, global climate change, and the living environment of swallows has been seriously damaged. Swallows live mainly in rural areas, and now the rural environment has undergone radical changes. In some places, there are many factories, and farmers plant more chemical fertilizers and pesticides, which increases pollution.

The laws of nature, natural selection, survival of the fittest, if you can't survive in a harsh environment, you will perish. This is the root cause of the lack of swallows. With the current housing structure, there are fewer and fewer places for swallows to nest, and it is becoming more and more difficult for swallows to find a suitable living environment.

containment, but while curbing pests, the food chain, which feeds on insects, has also suffered a big blow. Actually, it's not just the swallows that have become fewer. Like many birds that used to rely on insects, they are now very few of them.

With the development of society and the change of the environment, everything will change. This is true not only for swallows, but also for other animals. This is the law of nature.

Little swallows are dressed in floral clothes and come here every spring. I asked the swallows why they came, and they said that spring is the most beautiful here.

Nowadays farmers use some pesticides, which will affect the growth of swallows. Nowadays, some rural areas have a lot of pollutants, which ultimately affects the survival of animals.

In the past, when I was a child, I could see a lot of swallows flying around in the countryside, but in recent years, swallows have also become rare, all because of environmental problems.

The current environment has changed a lot, and the living habits of many organisms have been greatly affected.

There are two main reasons why swallows have rarely appeared in recent years:

1. The number of suitable nesting sites has been greatly reduced. Generally, swallows are roughly divided into two categories, one is the passerine swallow family, the more common is the golden-waisted swallow and the house swallow, the other is the swift family, the more common is the ordinary building swallow in the north and the small white-rumped swift in the south, the white-waisted swift, the house swallow, the golden-rumped swallow usually nest under the eaves, and now there are fewer and fewer traditional houses in the city, and many new buildings and buildings are not suitable for swallow nesting, because there is no eaves and a large number of glass curtain walls are used. Some properties for the sake of beauty, will even poke the swallow's nest down, swifts generally nest in the cracks of ancient buildings, but now in order to protect the ancient buildings, more and more buildings suitable for nesting have been pulled on the bird-proof net, making the breeding of swifts more and more difficult, so the number has decreased sharply in recent years, and it is difficult to see.

2. Destruction of man-made interests. Because of the sudden rise of bird's nest in recent years, some people are greedy for profit, looking for some buildings suitable for swallows to live in, destroying swallows' nests, so as to obtain bird's nests for sale, which hinders the breeding process of swallows and reduces the number.
