We watched these Mexican Free-tailed bats flying out of Bracken Cave for over an hour. With an estimate of more than 20 million bats, this is the largest colony in the world. It takes around 4 hours for the entire colony to fly out to hunt. In this video, they are leaving to fly approximately 50 miles to feast on boll weevils in Texas cotton fields.
