White-Nose Syndrome
A serious disease has been killing off bats in the United States and Canada. It was initially discovered in New York, but has now spread to many of the surrounding states and as far west as Oklahoma.
These bats have a white fungus growing on them during hibernation. This fungus is called Geomyces destructans. It is now estimated that over a million bats have died as a result of White-Nose Syndrome
