The Bat Mystery is Solved.....kind of.

A mystery has been lurking in bat caves across the northeast.

Late last winter and early spring, wildlife biologists reported that thousands of bats were dying of a mysterious ailment.

They called it white nose syndrome, because the dying and dead bats' noses were covered with a white powder.

In some caves, 90 percent of the bats were affected.

Emily Brunkhurst is a biologist with the New Hampshire Department of Fish and Game.

She's with the non-game and endangered wildlife program.

She tells NHPR's Mark Bevis the mystery has been solved....at least partially.
