Going Batty at Cumberland Caverns

One of our favorite questions to answer: Do you have bats in the cave?

Yes! Approximately 1500 little brown bats (scientific name: Myotis lucifugus) make Cumberland Caverns their home. Typically, bats live in areas of the cave that are not frequented by guests, but we do have a few who like to hang around on the rock ledges and overhangs of the Daily Walking Tour trail.

The bats that inhabit Cumberland Caverns are about 3.5” and weigh about 1/4 of an ounce when fully grown. Not only are they small, but they often blend in with the cave walls and go virtually undetected. Sometimes, we get lucky and see one flying high above the chandelier of the Volcano Room, but don’t worry, they are harmless and never encounter the humans below.

Bats are a very important part of the ecosystem. They are the primary predators of night-flying insects and studies suggest they consume 70% of their body weight each evening. That’s approximately 1000 insects per hour and nursing mothers can eat upwards of 4000 bugs in the same amount of time!  Bats are also beneficial in pollination and seed dispersal. Most people think that only birds and bees aid in pollination, but bats are the nightshift of the operation.



If you see bats around your home, have no fear; contrary to the urban myths, bats aren’t looking to take a bite out of you, they are just searching for a safe and warm place to call home.
