Why do swallows fly low before the rain? The answer justified by science

Since a long time swallows were harbingers of bad weather. Looking at their behavior, people could easily determine what will be the present day - rainy or sunny. At the same time, their "predictions" could not be doubted. In this regard, inquisitive minds have long been asked a completely logical question: why do swallows fly low before the rain?

For a long time the answer to this question eluded scientists. Years passed, and modern science still found a worthy explanation for this phenomenon. But let's talk about everything in order.

Forecasts in old times

Thanks to the progress of today, a person can easily find out the weather forecast on the Internet or in the news. But it was not always so. In the old days, the vagaries of nature could be recognized only by closely monitoring its clues. By the way, our ancestors did it very well.

Thanks to such observations, the light saw a lot of people's perceptions. In particular, that before the rain swallows begin to circle very low above the ground. At the same time, the accuracy of this observation was very high, as a result, the sign became one of the most famous in our region. But, despite this, the Slavs could not understand why swallows fly low before the rain?

Futile search for answers by scientists

The decision of this curious question was taken by scientists. After all, despite the fact that people's signs refer to the division of folklore, yet many of them have a scientific basis. So, the naturalists began to furiously seek an answer to the question: "Why do swallows fly low before the rain?"

Initially, scientists believed that swallows feel changes in the atmosphere, due to which they "predict" the weather. However, if this was true, then why did the flying swallow descend so low to the ground? Was not she supposed to be hiding from the approaching bad weather in her nest?

In general, as often happens, attempts to find an answer only increased the number of new riddles. And then one day the truth was revealed to the scientist. And, as it turned out, the truth was completely different from what the researchers had been searching for so long.

Rain and insects

I want to make a small digression and talk a little about insects. Or rather, about how they are approached by the approach of rain and increased moisture in the air. After all, it is in their behavior lies the clue of the behavior of the swift swallows.

So, the approach of rain is accompanied by an increase in atmospheric pressure. And if for us this phenomenon is not too noticeable (although meteodependent people can argue with this statement), then for insects this means significant changes. In particular, the force of the atmosphere seems to be pressing them to the ground.

After the pressure has risen, the air begins to permeate with the smallest droplets of water. Such moisture quickly settles on the wings and bodies of insects, thereby increasing their weight. And they can not fly fast anymore, let alone climb high above the ground. Therefore, the only thing that remains for them is to circle over the surface in search of a refuge.

Why do swallows fly low before the rain?

Well, now is the time to answer this question. As it turned out, the reason for everything is the brutal appetite of these birds. So it turned out that eating swallows - it's almost a continuous process, which they devote most of their day.

And since their favorite food with the approach of rain begins to spin around the earth, then they have no choice but to follow it. So it turns out that the main "meteorologists" are not the swallows themselves, but ... insects. But how did it happen that all the laurels got swallows?

The essence of the problem is that most insects are tiny. Therefore, people simply did not notice them, therefore, they could not draw a logical parallel. It is quite another matter - swallows, which are difficult to overlook. And yet, however that may be, the fact remains: if swallows fly low over the earth - be the rain.
