There is so much more than the stuff of halloween nightmares. Abcs ryan owens traveled to texas to witness the feeding frenzy. Reporter welcome to the batnado. Thats right, a real tornado of creepy creatures, a funnel of freaky fliers that emerges every night from this cave in texas. Look at that. And you feel the wind. Wow, look at them. We are in the middle of it right now. Reporter you are watching 20 million, yes, 20 million mexican freetail bats whirl their way out of the single cave to hunt for food. The way that theyre climbing up out of the hole. Gaining altitude. Like an airplane. Gaining altitude. Get up. You can see they keep their form. Go off into a river off, 30 miles away. Out to eat. 100 tons of bugs every night. Reporter our guide for this tour of the bracken bat wave north of san antonio is casey anderson, host of america the wild, on national wild. I love tracking predators. Reporter this guy has traveled the world and seen some of the most dangerous animals. And says he has never seen anything like this. It is the largest concentration of mammals on the planet. It its overwhelming to be, amongst all these bats. Reporter so many bats make the journey together every night. They even show up on the local radar. As many as we are seeing right now, this goes on for hours and hours just a steady stream. Yeah, this massive flow will go on for three hours sometimes. It just shows you how many bats are in that, in that cave. Its its, blows my mind. Reporter as close as we are here, you are telling me i am in no danger if one hit me in the head . No, only thing you are in danger of. You might feel look you are getting rained on. Thats not rain. Thats danger to me, lets be very clear we couldnt go in the cave from the dangerous level of c 02 from the bats guano. Casey did go inside a similar cave and it was truly the stuff of nightmares. Tell you what being here in the dark and having all the bugs falling from the ceiling. It is a little freaky. Reporter he argues despite all the childhood nightmares and cheesy horror movies like the aptly named bats. We really should like them. Nothing to fear here. Bats are super essential to every eco system theyre part of. In fact theyre actually our best friends. Middle of the summer. Hot here in texas. People think there are a lot of bugs now. If we didnt have these guys we would been real trouble. Ive couldnt iffage aimagi balts were bats were gone. We would live in a world covered by bugs. Thats to me something to beafraid of. Scarier than the bats . Absolutely. Reporter turns out the bats have a lot to be afraid of. As the we waited for them to emerge that night. We noticed skunks and raccoons gathering at the entrance hoping a couple of the 20 million fall out of the sky. Snakes show up at the buffet too. They dont always wait for the bats to hit the ground. Matt caught this snake snag one out of the air. Got one. He got one right there. Even if the bats make it high in the air. There is a predator waiting for them. Check out this hawk. Dinner time. Thats not to say some bats arent scary. Casey want to southern mexico in search of vampire bats. Yes, they do exist. And just like dracula, they only eat one thing. What a weird animal in the sense that is the only thing they eat blood. Truly. Its like the horror movies. But they dont look human blood. In fact theyre usually eating livestock or wild animals out there, the blood they prefer. Reporter there is Something Else vampire bats like. The heat. So for now theyre only blood sucking way down in mexico. There is some speculation as the the climate changes many species are going to start moving around. There is indications that vampire bats are coming north. You know . Here texas is cattle country. Plenty of food for the bats to eat. It could happen. Reporter until then, lets enjoy the harmless variety. There is something mesmerizing about watching the animals leave the socalled bat nado and trail off on their nightly commute. Almost like theyre on board a train we cant see. I think this is absolutely beautiful. If that was bird. People would love it. But its not. Its bats. But i think it is equally as beautiful. Maybe in some way a little more important. Reporter their commute is a long one. They fly as far as 30 miles in search of the insects. They return just before sunrise. Cramming 20 million bats back into the cave is something to see too. There is like an odd ballet to this. Cant believe i am using the word. I think you are spot on. Ballet. In respect to bats. 20 million of anything. In sync. Not bumping into each other verycvery much. That is a dance they do every night to get where they need to go. The night time is the right time for the bat. Reporter one of the greatest shows on earth courtesy of mother nature. Im ryan owens for nightline at brecken bat cave in texas.
