There are times when you get to witness something spectacular in nature, and watching birds migrate is one of the finest sights of all. To see a whole flock of flying birds is something majestic that you can't understand until you've experienced it for yourself.
That's what these people thought they were seeing, but as it turns out, they were dead wrong. What looked like hundreds of birds migrating actually ended up being thousands of bats going out for their nightly hunt.
I would turn the other way and run. I don't want any part of this. So freaky!
