Texas’ Bracken Bat Cave Is Home to the Largest Bat Colony in the World

Birdwatching is cool and all, but have you ever heard of bat-watching? The world's largest bat colony in Texas is at Bracken Bat Cave near San Antonio. During the summer months, you'll be able to see the Mexican free-tailed bats firsthand. To learn all about what makes this big bat colony, one of the largest things in Texas, such a neat thing to see, take a look below.

On the northern outskirts of San Antonio lies Bracken Cave, which, at first glance, doesn't look like anything too out of the ordinary.

Those familiar with the area, however, know that the world's largest bat colony makes its summer home in the depths of this rocky outcropping. Mating season, which runs from March to October, attracts more than 20 million Mexican free-tailed bats to the area each year.

Temperatures get up to about 104 degrees in the cave, so it serves as a perfect incubator. And like clockwork, the bats emerge from the cave at dusk on summer nights in search of food.

The sound of millions of wings flapping in unison fills the air as the creatures blanket the skies looking for bugs to eat. Collectively, the bats chow down on about 140 tons of flying beetles, winged ants, and moths every single night. If you want to see the spectacle firsthand, Bat Conservation International holds "Member Nights" in the summer. Joining is easy, and you will want to see the bats fly out of Bracken Cave in Texas—it's a sight to behold!

The sheer number of bats makes it hard to discern where the swarm ends and the sky begins. Although your eyes may deceive you at times, the noise is unmistakable. It's akin to steady rainfall, and the colony is also visible on weather radars.

Animal enthusiasts of all ages are sure to have a blast learning all about these unique creatures. If you're lucky, a staff member might even let you get up close and personal with one of the bats.

The schedule for Member Nights typically comes out in early spring on the Bat Conservation International website. We'll be waiting with bated breath! Visit the Texas Parks & Wildlife and Bat Conservation International websites to learn more.
