“Fear, including the fear of loud noises, is deeply rooted in the evolutionary history of all animals. Shying away from dangerous situations increases survival. For example, hiding away from loud thunderstorms and running away from the noise of falling rocks might save an animal’s life.
“But there is nowhere to hide from fireworks. What must it be like for the wild animals that delight us on walks and picnics to be confronted with such an inescapable barrage of sound?
“Unfortunately, scientists don’t know much about exactly how fireworks impact animals as they’re difficult to observe at night. But what we have learned is alarming. Our recent study, one of the first to study how fireworks affect wildlife, showed how physically distressed animals – in this case geese – were made by New Year’s firework celebrations.”
