Swallows fly to the south every winter, where exactly is the south?

The south is specifically the area south of Qinhuai, which is a general area.

The south specifically refers to the southern part of the monsoon region in eastern China, mainly from the south of the Qinling Mountains and the Huai River, mainly including Jiangsu, Hubei, Chongqing, Anhui, Sichuan, Yunnan, Guizhou, Jiangxi, Hunan, Guangzhou, Fujian, Guangxi and other places.

The location of the south is in the south of the world, involving many regions, that is, the north of the guide is the place south of the Qinling Huai River, including Jiangsu, Anhui, Hunan, Hubei, Sichuan, Yunnan, Guizhou, Guangdong, Guangxi, Fujian, Jiangxi, Zhejiang.

It refers to a warm place, a place suitable for survival, and the place where different birds are suitable is completely different, there is no specific location, most of them will be in some warmer places.

Specifically, Hainan, Yunnan, and Taiwan are located in the tropics and are relatively warm.

The south is talking about Hainan, Yunnan, Taiwan, Sanya, Hunan, Sichuan and other tropical regions, these places have relatively high temperatures, so they are called the southern region.

These swallows will fly to some very warm places, and generally fly south to spend the winter.

I think they will fly to Sichuan, Hunan, Chengdu, Xianyang, Changsha and some other places.

Swallows from East Asia fly to Southeast Asia and Australia in search of a suitable living environment.

Little swallows wear flower clothes and come here every spring This well-known children's song lets us know from an early age that when spring comes, swallows will also fly back from the south. This makes people wonder where the swallows fly south when winter comes.

The swallow is a famous summer migratory bird in our country, which migrates to the north in early spring every year and spreads all over the country in summer. Because swallows are accustomed to preying on flying insects in the air, they are not good at searching for food in the cracks of trees and in the ground, and their mouths are particularly tricky, and they do not eat other foods such as berries or flowers and leaves, so when there are no flying insects in winter, swallows can only fly south in flocks to warmer climates in order to make a living.

The migration distance of swallows in China is also unimaginable, and the destination is generally in Hainan, Taiwan and other tropical regions. Further afield, they will even fly to Southeast Asia for the winter. You must know that from the northeast of China to Hainan, there are nearly 4,000 kilometers, and you can imagine the difficulty of migration.

And the swallows in Europe are more tenacious. In autumn, it crosses the entire Mediterranean, through the Sahara Desert, to the south of Africa for the winter, and truly crosses the mountains and the sea. Every migration is an adventure that can cost you your life.

The swallows return to the south around September.

The swallow is a migratory bird that flies from the north to the south in flocks around September before winter arrives, and returns to the north in March when the spring flowers bloom to have children and live and work in peace and contentment.

Swallows are excellent air travelers. In autumn and winter, they fly from their home Siberia in flocks to the south of our country to spend the winter. The following spring, they return to Siberia after a long journey to lay eggs for breeding.

The swallow is a migratory bird that flies from the north to the south in flocks around November before the onset of winter, and returns to the north in March when the spring flowers bloom and live in peace and contentment.

Swallows generally migrate to southern regions such as Hainan, Yunnan, Guangzhou, etc., because these areas have relatively high temperatures, and they are not cold in winter, and they can also look for food, while there is no food to look for in the cold north.

The south is the location south of the Qinling Huai River, and the location of the south of the Qinling Huai River is collectively referred to as the south, and our country uses the Qinling Huai River to distinguish the north and the south.

Some swallows will choose to fly to Hainan, Yunnan, Guangdong and other places, and some will choose to fly to Southeast Asian countries.

Swallows from the north fly to the south in winter.

1. The range of swallow migration is very wide. Swallows that survive in northern and northeastern China in summer usually overwinter in Guangdong, Guangxi, Yunnan, Fujian, Jiangxi and southern Hunan in winter, but many will fly to Vietnam and Laos, which belong to Southeast Asia.

Myanmar, Cambodia.

Thailand and other places, and even some will fly to Malaysia and Indonesia.

The length of their migration also varies.

2. Why do swallows fly south? Swallows fly south, not just because the weather in the north is colder, but because when the weather in the north gets colder, insects tend to stop their activities and burrow into small burrows to spend the winter, so there are fewer insects active outside, and even fewer insects fly.

The swallow flies to the warm south, not to the south of our country, but to the vicinity of the earth's world, and even to the southern hemisphere. For example, the swallows in the north of our country fly to the south, and they will generally fly to Hainan or Yunnan, Guangdong and other places, and some swallows will go to Southeast Asia. European swallows generally fly farther, possibly across the Sahara Desert to southern Africa for the winter.

The Sahara Desert is very dry and there is no water, only a small oasis, and the water is definitely not enough, so swallows generally catch mosquitoes here.

They usually go to the south to spend the winter in winter, flying over in groups; Most of the swallows choose to spend the winter in tropical provinces such as Hainan, Yunnan, and Taiwan, which belong to the south.

This is due to the fact that the weather in the north is colder in winter, so it is necessary to fly to the south. It refers to the places to the south, the cities and provinces to the south.

In China, the Qinling Mountains and the Huai River are divided into north and south, but the swallows migrate not only south of the Qinling Mountains and the Huai River, but also Australia, Africa, South America and other places in the southern hemisphere.

The southward migration of swallows is mainly based on temperature and distance, and the main southward migration footholds of swallows are countries such as South Asia and Southeast Asia, if the temperature in these places is not suitable, swallows will continue to move south to near the equator.

From the global migratory bird migration roadmap.

Swallows from East Asia fly to Southeast Asia and Australia.

Swallows from Central Asia fly to India in South Asia.

European swallows fly to Africa.

Swallows from North America fly to South America.

Swallows fly south for the winter, and where do they fly to the south? Probably more south than you think.

<> "Swallows fly to the south for wintering, so where is the south?"

We often associate cold with migration, but in fact, homeotherms like birds are very adaptable to the cold, so they are not simply repelled by the cold, the real reason is mainly food.

When the weather gets colder, some birds have less access to food such as insects, so they choose to migrate to an area where food is more abundant.

These seasonal migratory birds are called migratory birds, and most of the time migratory birds have higher food requirements, and they are usually birds that completely prey on insects; The counterpart to migratory birds is the resident bird, which as the name suggests, is a bird that stays in place for the winter, and these birds are often characterized by not being picky eaters.

Some migratory birds can move very briefly, such as from the top of the mountain to the foot of the mountain, so that the temperature will change, the biome will change accordingly, and they can eat their favorite food again.

At this time, it probably shouldn't be called the south, it should be an upward or downward migration.

Some migratory birds migrate over the middle distance, moving only a thousand kilometres south, finding an area with plenty of food and staying until spring, when they continue north to complete their breeding efforts.

Migratory birds that migrate over the middle distance are basically a relatively warm area in the south, and they are not fixed, and the weather continues to turn cold, and they continue to migrate south after the food decreases.

What's really interesting are the migratory birds that cross the continental plate and fly tens of thousands of kilometers over a period of several months, which we can call long-distance migration.

They migrate from areas with cold winters to tropical regions with no significant seasonal variations, and the tropics are the southern part of these migratory birds.

Although the migration routes, distances, and timings of some migratory birds are very alarming, the most strange behavior of these birds is that they return in the spring compared to the wintering migrations of migratory birds.

They abandon a wintering site that is less likely to have significant seasonal variations – less frequent changes in food – and choose to spend a long flight to a place where there are significant seasonal variations.

What's even more interesting is that the return migratory birds are more hasty than their wintering migrations, and they have a clear sense of going straight to their destinations.

In fact, as far as the available evidence goes, most of the migratory birds that migrate to the tropics for the winter originate in the tropics and then migrate seasonally to other places, just returning home in the winter.

Migratory birds, like all migratory animals, are all about breeding, and the first thing you do when you come back is to build a nest, and then you can produce offspring, raise them and leave.

In general, migratory birds can raise 4-6 offspring at a time, while their tropical relatives can only raise 2-3 offspring.
