Warning’ birds
Like all animals, birds are very intuitive. And at the first sign that something may go wrong is that they flee. They take care of each other, emigrating in droves. What’s important about this is that if you see a lot of wings flying in one direction, it may be because a tornado is approaching.
This is scientifically proven. Physicists and meteorologists have proven this for decades. Storms and tornadoes generate sound waves that travel through the air for miles, which is why different birds migrate, due to these frequencies.
