Why Wind Turbines Can Mean Death For Bats

Power-generating wind turbines have long been recognized as a
potentially life-threatening hazard for birds. But at most wind
facilities, bats actually die in much greater numbers. Now, researchers
reporting in Current Biology, a Cell Press journal, on August 26th
think they know why.

“Because bats can detect objects with echolocation, they seldom collide
with man-made structures,” said Erin Baerwald of the University of
Calgary in Canada. “An atmospheric-pressure drop at wind-turbine blades
is an undetectable—and potentially unforeseeable—hazard for
bats, thus partially explaining the large number of bat fatalities at
these specific structures.
