Do wind turbines kill 8,000-10,000 birds a year?
Certainly not each single wind turbine, or for that matter an entire wind project kill that many birds. Everything has an impact, for example the vehicles that we drive emit green house gases that impacts birds, but let’s keep things in perspective. For every 10,000 birds killed by human activities including fatalities by collisions with man made structures, less than one death is caused by a wind turbine. American house cat poses a much greater threat to birds than wind turbines. Housecats are estimated to kill 10.6% birds each year in the U.S. compared to less than 0.01% birds that die from a collision with turbines, thus averaging 1-2 birds per wind turbine. Not all wind turbines kill birds all the time at all places, besides bird migration and habitat study to properly site turbines is a requirement for environmental permit.
