It's been nearly 14 years since "white-nose syndrome," named for a white powder-looking fungus found on the nose of bats, was first identified on a bat in New York. Since then the disease has moved westward, leaving millions of dead bats in its wake. At Mammoth Cave National Park in Kentucky, the disease is blamed for the loss of 75-80 percent of Tri-colored bats there.
National Park Service staff at the park say Tri-colored bats were once among the most often seen bat species in the cave. Today White-Nose Syndrome has made it a much more rare event. If you see one of this species, consider yourself fortunate.
