Barotrauma is a significant cause of bat fatalities at wind turbines
Author: Baerwald, Erin; D'Amours, Genevieve; Klug, Brandon; and Barclay, Robert
Summary. Bird fatalities at some wind energy facilities around the world have been documented for decades, but the issue of bat fatalities at such facilities — primarily involving migratory species during autumn migration — has been raised relatively recently. Given that echolocating bats detect moving objects better than stationary ones, their relatively high fatality rate is perplexing, and numerous explanations have been proposed. The decompression hypothesis proposes that bats are killed by barotrauma caused by rapid air-pressure reduction near moving . . .
