Another interesting story from science journalist DeLene Beeland:
“…Leaf litter is piled up in drifts on the cave floor. The camera zooms in, and suddenly you realize these are not leaves… they are bats: hundreds and hundreds of dead bats. The footage is all the sadder because this cave houses the largest colony of hibernating bats in the northeast.
…summer surveys will collect wing punches and hair samples to investigate if pesticides or heavy metals from their insect prey base are building up in their bodies.”
