Why swallows fly low before rain? The answer is substantiated with science

Since ancient times, the swallow was a harbinger of bad weather. Looking at their behavior, people could easily determine what the current day is rainy or Sunny. Thus in the accuracy of their "predictions" could be no doubt. In this regard, inquiring minds have long asked the logical question: why swallows fly low before rain?

For a Long time the answer to this question has eluded scientists. Years passed, and modern science has still found a decent explanation for this phenomenon. But let's take first things first.

Forecasts in ancient times

But despite this, the Slavs were never able to understand why swallows fly low before rain?

Vain search of the answer scientists

The Solution of this interesting question, scientists do. After all, despite what people's signs are related to folklore, yet many of them have a scientific basis. So, naturalists began furiously looking for the answer to the question: “why swallows fly low before rain?”

Originally, scientists believed that swallows feel the change in the atmosphere, thereby "predict" the weather. However, if this were true, then why the flying swallow down so low to the ground? Isn't she supposed to hide from the approaching bad weather in your nest?

In General, as is often the case, attempts to find the answer only increased the number of new riddles. And once the truth was revealed to scientists. And, as it turned out, the truth was quite different from the stuff you've been looking for the researchers.

Rain and insects

I Want to digress and talk a little bit about insects. Or rather, about how they are affected by the approaching rain and increased moisture in the air. It is in their behavior lies the key to smart behavior of swallows.

So, the approach of rain accompanied by an increase in atmospheric pressure. And if such a phenomenon is not too obvious (though meteodependent people can argue with this statement), for insects it means significant changes. In particular, the power of the atmosphere like presses them to the ground.

After the pressure is increased, the air becomes impregnated with tiny water droplets. This moisture quickly accumulates on the wings and bodies of insects, thereby increasing their weight. And they can quickly fly, and especially to climb high above the ground. So the only thing they can do – to hover above the surface in search of refuge.

Why swallows fly low before rain?

Well, here it is time to give an answer to this question. As it turned out, the cause of all - the brutal appetite of these birds. It just so happened that the food of swallows – it is almost a continuous process, to which they dedicate a large part of your day.

As well as their favorite food with the approaching rain begins to circle the earth, then they have no choice but to follow him. And so it turns out that the main "meteorologists" are not themselves the swallows, and... insects. But as it turned out that all the credit went to the swallows?

The problem is that most insects are tiny. So people simply did not notice them, therefore, could not draw a logical parallel. Quite another thing - swallows, which are difficult to overlook. And yet, whatever it was, the fact remains that if the swallows fly low over the ground – to rain.
