White-nose syndrome (WNS) is the name used to describe a group of symptoms associated with the deaths of millions of bats in the USA (40 states) and Canada (eight provinces), according to figures from the US Fish and Wildlife Service. In some hibernation sites numbers have declined by 80-100% since 2006, when the condition was first identified.

The video Battle For Bats: Surviving White Nose Syndrome shows what is being done in the United States to mitigate the effects of WNS on bat populations.
