Meet the Bats of Bristol Caverns

While most visitors come to Bristol Caverns for our towering formations and underground rivers, some of our smallest residents play a big role in the ecosystem—our small colony of about twenty tricolored bats.

Who are the Tricolored Bats?

Tricolored bats (formerly known as Eastern pipistrelles) are one of the smallest bat species in North America. These gentle creatures are named for the three distinct colors on each strand of their fur. They’re completely harmless to humans and help control insect populations—think of them as our natural pest control team!

What is White Nose Syndrome?

Sadly, bats across the country are facing a deadly threat: White-Nose Syndrome (WNS). This disease is caused by a cold-loving fungus that infects hibernating bats, disturbing their sleep cycles and draining their energy reserves. Most affected bats die of starvation before spring. WNS is not dangerous to humans or pets, but we can still unintentionally carry the fungus from one cave to another on our shoes, clothes, or gear.

How You Can Help

Bristol Caverns is committed to protecting our small bat population, and you can be part of that effort. Here’s how:

• Wear clean clothes and shoes that haven’t been in other caves or mines.
• Follow all posted signs and staff instructions regarding wildlife-sensitive areas.
• Don’t touch or disturb the bats—even small interactions can disrupt their delicate routines.
• Learn and share what you know about WNS and bat conservation!

Thankfully, our bats often sleep far away from us, meaning that we seldom have to worry about infecting them, but these steps can ensure that our colony remains healthy and happy.

Whether you spot a bat nestled high in the ceiling or silently passing overhead, remember—you’re sharing the space with some of nature’s most remarkable creatures.
