WILKES-BARRE -- Sue Gallagher of the Carbon County Environmental Center has presented her educational program on bats so many times she could probably do it hanging upside down in the dark.

She ran through much of that program Thursday at Wilkes-Barre’s River Common, going over myths and misconceptions about nature’s only flying mammals. To summarize: Bats aren’t blind, they aren’t flying mice, they won’t get stuck in your hair and, unless you’re vacationing on a South American cattle ranch, they won’t suck your blood either.

A little more than a year ago, things changed, and Gallagher’s message about bats changed with it.

Bats in Pennsylvania are dying, Gallagher said, in such extreme numbers that future generations of Pennsylvanians may never see them in the wild.

“You guys aren’t going to grow up seeing bats the way we grew up seeing bats,” Gallagher told the approximately 10 children who gathered with their parents for the program, which was sponsored by rivercommon.org.

There are two culprits in the disappearance of the state’s bats, Gallagher said.

Hibernating bats, the sort that live in caves, have been affected by white nose syndrome, a fungus-based illness that causes bats to awaken from hibernation early. The bats, which live on a diet of insects, then die of starvation.

The illness, which spread south from New York State last year, kills 85 to 100 percent of bat populations it infiltrates.

Other bats, especially the migratory variety, are being killed by an unlikely source: wind turbines. Bats are attracted to the turbines during mating season, Gallagher said, when they will fly to the highest point above ground. They are then either killed by the large fan blades or by low pressure systems that form near the tips of the blades that cause the bats’ lungs to explode.

A single turbine can kill 50 to 100 bats a year, Gallagher said, adding that it is too early to judge the effect of wind energy on bats because Pennsylvania does not track bat population size.

“We want to get behind wind energy; we want to say wind energy is green, but we’ve got to address its impact on bats,” Gallagher said.

“I feel bad, because I really like bats, and I don’t want them to die,” Bethany Kelsey, 7, of Wilkes-Barre, said after the program.

“I didn’t know that they were dying, which makes me very sad,” Kelsey’s mother, Angel Kelsey, added. “I grew up in the woods watching the bats.”

The bat program was the first in a series of free children’s nature education programs being held at the River Common. The next, a live mammals program, will take place July 23.
