White nose syndrome, a deadly fungal disease that has been spreading through the country, has claimed all but 23 of some 10,000 bats in one of the largest colonies in Pennsylvania. Of the surviving bats in an abandoned mine in Upper Bucks, about half show symptoms of the illness, according to Pennsylvania Game Commission biologist Greg Turner. Almost all of the state's cave-dwelling bat population has been felled, according to Turner. "Going to places where there used to be tens of thousand bats hibernating, and then going in and seeing only a few bats -- only a few stragglers left -- that's very difficult," he said.
