Discovered in 2007, White Nose Syndrome is an illness plaguing certain hibernating bats in the eastern United States and Canada (and is spreading).
Cave dwelling bats can develop the illness from a contagious fungus called Pseudogymnoascus destructans (Pd). The fungus grows in cold damp areas, making caves an ideal location. The fungus attaches to the bats skin making its nose appear white, hence the name White-Nose.
The illness causes bats to leave hibernation early causing death.
