Changing Your Car Could Cost You 700,000 Won More a Year... Why Your Vehicle Is Targeted by Bird Droppings

Brown Cars Most Frequently Targeted by Bird Droppings
Tesla and BMW Owners Spend More on Bird Dropping Damage

One in four American drivers spends more than 700,000 won annually on car washes and repairs due to bird droppings, and a study has found that vehicles of certain colors are more frequently targeted by bird droppings. On October 11 (local time), the American science magazine StudyFinds reported that, according to a survey conducted by garage and carport retailer Alan's Factory Outlet with 1,000 American drivers, brown cars are the most frequently hit by bird droppings. Red and black vehicles followed brown in the frequency of bird droppings. White and silver cars experienced the least bird droppings, suggesting that lighter colors provide some degree of protection.

Scientists explain that the reason certain colors attract more bird droppings is related to the characteristics of birds. Birds have the ability to detect ultraviolet light, allowing them to distinguish colors better than humans. Certain hues stand out more in a bird’s field of vision, which is believed to be why darker-colored vehicles become primary targets. Shiny surfaces also play a role; the hood and side mirrors reflect the bird’s image like a mirror. During mating season, birds with strong territorial instincts may mistake their reflection for a rival and repeatedly attack the same vehicle.

Meanwhile, damage from bird droppings poses a significant financial burden for Americans. Among those surveyed, 24% said they spend more than $500 (approximately 710,000 won) annually on car washes and repairs related to bird droppings. Owners of Tesla and BMW vehicles were found to have the highest proportion of high expenditures, with two-thirds of each brand’s drivers reporting annual spending of over $500 to deal with bird droppings.

StudyFinds noted that while bird behavior cannot be changed, the most effective way to minimize damage is to park in covered areas. Additionally, using a car cover can be an alternative if long-term outdoor parking is unavoidable, and avoiding parking under trees, power lines, or eaves where birds frequently perch can also help reduce the risk of bird droppings.
