Car colour could dictate amount of bird droppings on your paintwork

It’s the bane of the car owners’ life – bird droppings on the paintwork. Eradicating them bodywork can take ages, and if left on a car’s paintwork, can eat away at the compound and strip away the surface finish, potentially costing you in the long run.

But there could actually be a preventative measure you can take, to help minimise the amount of bird droppings on your shiny new car.

It may actually be all down to colour. According to a study by Halfords, red cars are the largest targets for birds, with 18% of crimson motors found to have traces of bird droppings on their paintwork. Blue cars didn’t fair much better either, recording a 14% dropping rate.

Black, white, silver/grey, and green rounded the top six, with 11%, 7%, 3% and 1% of vehicles exhibiting traces of bird poo on the paintwork respectively.

And the reason for this unusual pattern? Surely birds can’t be selective in where they do their business? Well, no. There’s no scientific evidence to explain this – it’s just one theory as to why cars are so susceptible to bird droppings.

Plenty of other theories have been bandied about, including that birds ‘poop’ in response to their own reflection, with highly polished and deeply coloured cars attracting the largest proportion of droppings.

Dispelling this is the theory is that it’s purely down to chance, and is largely determined by where you park your car. If you’re particularly worried about your car getting attacked by bird dung, then we suggest you steer clear of tree-covered parking spots.

Whatever the cause, there’s no denying the damage it can cause. According to car care specialists Autoglym, rather than the acid or alkali contained in bird faeces, it’s the softening effect on a car’s paint lacquer that causes the damage.

Once moisture mixes with droppings, expansion occurs forming an uneven mould around the deposit producing a dull patch on the car’s bodywork.

If you want to get intricate, it’s the more grainy textures from seed-eating birds that give the most blemishes, making pigeons worse than seagulls.

If you live by the seaside, you could be in luck. If you live in the city, it might be time to invest in some car polish.
