For a long time, swallows were forerunnersbad 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.
Thanks to the progress of today, a person withEasily can find 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 sawset of people's signs. 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?
The solution to this curious question was taken upscientists. 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 the swallows feelchanges in the atmosphere, due to which "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 it often happens, attempts to findthe 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.
I want to make a small digression andtalk 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 byincreased atmospheric pressure. And if for us this phenomenon is not very 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 crush them to the ground.
After the pressure rose, the airbegins 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 circling above the surface in search of a refuge.
Well, now is the time to give an answer to thisquestion. As it turned out, the reason for everything is the brutal appetite of these birds. It so happened that eating swallows - it's almost a continuous process, which they devote most of their day.
And since their favorite food with approachingthe rain begins to circle the earth, then they have nothing else to do but 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 insectstiny. 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.
