Multitudes of bats die around the world each year when they migrate through electricity-generating wind farms. University of Calgary researchers now say the main cause of death is "barotrauma": the turbines' large revolving blades create low-pressure zones that cause bat lungs suddenly to over-expand, tear and bleed.

Only the ones that get too near a wind farm die from barotrauma. The bats dying from the fungus is a different problem. You probably heard of this recently because a USGS scientist (see http://www.usgs.gov/newsroom/article.asp?ID=2058) identified the fungus and published the news a few weeks ago.

Are all bats dying from "barotrauma"? I had heard that it was a fungus killing them. We saw very few bats this past summer.
