How Many Bats Are Killed by Wind Turbines Each Year? Increased hazard is especially true in North America, as these birds frequently crosswind turbines during their migration journey. This risk is because songbirds are migratory, and as they migrate, they encounter clusters of wind turbines striking and killing them. The songbird species is most at risk of dying from collisions with wind turbines. Though any bird is at risk of dying when encountering a moving small wind turbine, there are some species that are more frequently killed by turbines than others. That being said, we should still aim to make changes in the future as the current number of bird and bat fatalities is still unacceptable. However, experts suggest that though these numbers seem astronomical, wind turbines don’t actually kill as many birds as we might fear, at least compared to other factors that kill birds regularly. This staggering number doesn’t even include the number of bats that fall prey to these turbines. Sadly, when you hear that many birds and bats are killed by wind turbines each year, it’s not an exaggeration.Īs of a study done in 2012, it is estimated that over 1,098,093 birds are killed by wind turbines each year. Number of Birds Killed by Wind Turbines Each Year However, this would not help the bat populations who primarily travel at night. This measure would at least allow the bird to see the turbines better as they fly, making it less likely that they will run into them during flight. There does seem to be some research about how painting a single turbine wing black could help drop the bird death toll by 70% if implemented. However, larger turbines have more moving parts for birds or bats to hit or get stuck in, and many of these creatures succumb to turbines every year. Instead, birds have more time to get out of the way due to the significant rotation of bigger turbines. More robust wind turbines do not kill more birds and bats each year than small wind turbines. Do Larger Wind Turbines Kill More Birds and Bats? This answer can vary based on the turbine design and location. There is quite a lot of debate surrounding whether large or small wind turbines kill more birds and bats each year. However, large turbines also kill thousands of bats and birds each year. It’s reported that birds and bats are more likely to be killed by small turbines (provided they are not small homemade ones) due to their movement design. Small wind turbines do kill birds and bats.
