Country File magazine reports on recent research by Manchester Metropolitan University with Manchester Airport that found birds living near airports “are exposed to extreme noise levels from jet engines” which interferes with communication during breeding season. Interestingly, not only is communication affected, but the researchers found that common chiffchaffs living near loud aircraft were five times more likely to attack a speaker playing bird song than chiffchaffs who lived further away from airports. That is, the noise made the birds more aggressive.
We were not entirely surprised that noise would cause aggression in animals, as some studies show that noise causes or exacerbates aggression among humans.
Just another reason to lower the volume, everywhere.
