A study has revealed that a wind turbine’s colour affects how many insects it attracts, shedding more light on why the turbines occasionally kill bats and birds.
Scientists say that turbines, most commonly painted white or grey, draw in insects. These then lure bats and birds – as they pursue their prey – into the path of the turbine blades.
Support for the idea comes from another study showing that bats are most often killed by turbines at night and in summer, when insects are most abundant.

“It had been speculated that insects may be attracted to turbine structures for some reason and this then could attract insectivorous species, such as birds and bats, to forage in the vicinity,” said PhD student Chloe Long of Loughborough University, UK. Continue reading
