A British study reported by the Daily Mail said that birds are most likely to leave "their mark" on red cars, while green cars were apparently of little interest. The observational study found that 18 percent of red cars had bird droppings, while just 1 percent of green cars had been tagged by the winged bombers.
The study also asked drivers how quickly they take care of bird droppings on their cars. About one in six said that they clean up droppings as soon as they spot them, but more than half leave the deposits on their cars until their next visit to a car wash.
The analysis covered more than 1,100 cars in Brighton, Bristol, Glasgow, Leeds and Manchester in the United Kingdom.
