A new study out of the UK has revealed the colours to avoid if bird doo-doo baking onto the bonnet of your car figures among your peeves.
While white is the leading preference for humans when it comes to cars - as a colour choice friends, not, you'll be pleased to know, in any scatological sense - the study by UK retailer Halfords shows that red marks the spot for our feathered foes.
Recording the number of deuces dropped on 1140 cars in Brighton, Glasgow, Leeds, Manchester and Bristol, the study found red was most popular, taking 18 percent of the avian vote.
Perhaps for its watery look, blue (14%) also proved popular, followed by black (11%), white (7%), grey/silver (3%) and green (1%) - the latter possibly skipped for appearing too much like a boring old hedge.
Drivers were also asked how quickly they removed droppings from their cars.
Only 17 percent said they wiped off deposits as soon as they're discovered, 20 percent said they took action "within a couple of days," and 55 per cent waited until the next car wash.
The remaining eight percent never wash their cars, or leave it to others to organise.
Asked for their thoughts on why birds target certain colours - if at all - drivers could shed no light on what made their cars especially attractive as a target for birds.
We should all, of course, give daily thanks that cows, giraffes and camels haven't yet learned how to fly. Perhaps that's something else Halfords could look into when they have a few more idle moments to fill.
