There is a fungus called White- Nosed syndrome, and it's affecting hibernating bats the most. So far, the fungus has killed millions of bats eastern U.S. Scientists have found the fungus in a 390 mile long cave ( Kentucky's Mammoth Cave National Park.) The cave has been closed for closed to the public for close to 100 years, but they are allowing it to stay open. They are making careful precautions in order to make tourists safe. This syndrome is causing these bats to behave awkwardly. All we can do is hope for the best and pray for these bats.
