Why do birds fly south

 Why do birds fly south?

The night got longer, the weather was filled with freshness and frost, the plants were covered with the first frost, and the birds were ready to travel longer. Yes, autumn is coming and with it it is time to go to the tropics.

Not for us, but for our brethren. They eat more and actively store fat, which will save them from cold weather and satisfy the body with energy. At one point the leader of the flock landed his head south, and later he got another bird to fly south.

Some birds walk alone, because their sky knows where to fly. Of course, not all birds fly south. Thus, such familiar birds as birds, magpies, tits and crows feel good in the winter.

They can fly into the city and feed on the food that people give them, and these birds will not fly away to the tropics. However, most of the birds like to fly out.

Makes the winter migration of birds

Have you ever wondered why birds fly south and back? After all, they can stay in one place and avoid prolonged flight and avoid the flight. There are many theories about this. One of them is because winter has come - you say and you will do something.

He gets cold in the winter and they have to change the weather. But the flu itself is not why birds leave their fields. Adequate plumage protects the bird from freezing. You might be surprised, but the canary can survive at temperatures of -40, if, of course, there is nothing wrong with food.

Another reason for the flight of birds is the lack of food during the winter. The energy received from the food is eaten more quickly, by this it follows that the birds need to eat more and more. And since the winter not only plants freeze, but also the earth, the insects also disappeared, so it will be difficult for birds to find food.

Evidence of why many birds fly south due to lack of food is that when there is enough food to pass through, some birds migrate to their country during the winter.

However, of course this answer can not be final. The following assumptions are still controversial. Birds are known as nature to replace their place. Some scholars suggest that it was he who caused them to travel so long and dangerous, and then returned a few months later.

Yes, the behavior of birds is not well understood and hides in itself many unknown, answers that scientists have not yet seen. There are other interesting ideas as to why birds fly south during the fall and back. The desire to return home is associated with physical changes during open mating.

The glands begin to work to store hormones as a periodic improvement of the gonads occurs, which causes the birds to travel longer distances indoors. The last theory of why birds like to return home is based on the fact that for many birds it will be easier to breed in the middle latitudes than in the warmer south. Since birds migrate throughout the day, a long day has more to feed their young.

Animals have unknown sounds

Why birds fly south has not been fully studied, and it is unlikely that there will be a scientist who can prove the non-disclosure of this or the theory of winter migration landing. Judge for yourself the disadvantages of flying of certain species of birds.

For example, the swallow prefers winter in the American continent, where the sun is warm during the winter. Why is a swallow flying across Europe and Africa when temperatures are so close? If you bring such a bird as a petrel, then it flies from Antarctica to the North Pole, where there can be no talking of warmth.

Winter birds are not threatened by cold weather or lack of food, but after breeding, they fly to distant lands. So, the crazy gunman (who can be confused with our boat) flies to Amazon every year, and during marriage, flies back to East India.

It is generally accepted that when the fall season arrives, events are less favorable for southern birds. For example, in areas with fair weather, with moderate winds, there are often storms, and those that can not be seen in countries with bad weather.

Birds fly to areas with bad weather to release areas with a dry season. Thus, for the owl, the quality of nesting is in the tundra. Cool summers and plenty of food such as lemmings make the tundra an ideal place.

In winter, much of the snow falls into the forest-steppe of the central region. As you may have already guessed, the owl will not be able to stay in the hot summer months, and so in the summer it returns to the tundra again.
