600,000 Bats Killed at Wind Energy Facilities

Over 600,000 bats were killed by wind energy turbines across the United States last year, with the highest concentration of kills in the Appalachian Mountains, according to new research. In a paper published Friday in the journal BioScience, University of Colorado biologist Mark Hayes used records of dead bats found beneath wind generators, and statistical analysis, to estimate how many bats were struck and killed by generator propellers each year. "Dead bats are being found underneath wind turbines across North America," Hayes wrote. "This estimate of bat fatalities is probably conservative." The new estimate is among the highest yet for generator-related bat deaths. Previous studies have calculated mortality rates of between 33,000 and 888,000 a year. Read More at the latimes.com.
