About an hour or two before sunset, you can hear and see hundreds of bats fluttering and chirping just inside the cave, she said. Gradually, they come out to fly in a circle just outside the mouth of the cave, and eventually they move up into the sky in a spiral reaching several hundred feet in the air, like a huge bat tornado. Finally, the bats start breaking off into columns and move across the countryside. This can last for two hours or more.
Ritter takes care to point out that Mexican (also called Brazilian) free-tailed bats and other bat species provide benefits to humans beyond an awesome spectacle. They are major consumers of flying insect pests scientists estimate this species eats 6,000 to 18,000 metric tons of insects annually in Texas providing significant assistance to agriculture.
