In the migration seasons as bat species that
In “Wind farm turbines proving deadly for birds, bats” Richard Blackwell explains that high numbers of bats and birds are being killed by Wind farm turbines interactions with Birds, Bats, and their Habitats. These figures are considered large and could oppose a real threat to few endangered species. And wind farm turbines should not be built in important bird areas or in places that bats or birds use as migratory corridors or at least during a certain time of each year these wind turbines should be shut down in order to reduce bats and birds mortality. At last, he added that it is a complex process to figure out exactly when or how many birds or bats are being killed each year (Blackwell 2010). Question: Which season the peak season for bat fatalities by wind farm turbines facilities? The highest number of bat fatalities in North America have been registered in late summer and the in the beginning of fall, the same seasonal trends have been found in northern Europe. The reason behind this trend is that there is a relationship between bat fatalities and the migration seasons; migration of bats takes place from March till May and again from August through November (Kunz et al. 2007a). And, there is a noticeably smaller reported spike in bat death that happens during spring migration for some species at certain wind turbines .However, this low numbers could be due to the lack of monitoring studies that are being made during spring migratory periods (Arnett et al. 2008).The article from the newspaper does not conflict with the information that was provided in the scholarly journal articles. The newspaper article indicated the harm caused by wind turbines for bats and birds, and the importance of shutting down these turbines in the migratory periods, however, more data should be gathered before coming to any final conclusions (Blackwell 2010). In the same way, the primary literature demonstrates how bats are at risk of being killed by farm wind turbines facilities during summer migration season and more assessment is needed (Kunz et al. 2007a).
In spite of the environmental benefits of wind energy, it has a negative impact on bats and can be deadly for them. And especially in the migration seasons as bat species that migrate longer distances show more fatalities. Further Multi-year monitoring and research should be made to properly address the environmental risks and the impacts of wind turbines on bats.
