Biologists have confirmed that bats in Pennsylvania are infected with a mysterious syndrome that has already killed thousands of bats throughout the Northeast over the past two years. White Nose Syndrome (WNS), so called for the presence of a pale, powdery fungus on the muzzles of infected bats, has hit New York and Vermont bat populations hardest, and it seems to be continuing its march west. The pathology of White Nose Syndrome remains largely unexplained, but infected bats appear to starve to death after exhibiting non-typical behavior, such as flying during the daytime. Some biologists suggest that the fungus is merely a secondary infection that targets the already weakened immune systems of sick bats.
