why do birds poop on cars

Birds are mostly attracted to the color red, followed by blue and green. That’s one of the reasons ‘why do birds poop on cars?’. However, most of the time, bird droppings are found on vehicles that are parked under a tree or electrical cables.

The colors of the cars play a huge role in the avian droppings because of the reflection they produce. And though bird poop is depressing, the dropping actually means good luck and a time to reflect.

Interesting Facts as to Why Birds Leave Waste on Cars

Do birds poop on cars on purpose? Like humans, releasing waste from the body is a natural thing. Avians excrete poop to lessen their weight, and they have no proper toilet like we do.

But though pooping is inevitable, why do birds leave droppings on cars? And why specifically on certain colors?

Car Colors That Receive Bird Poop More Often

Thanks to a study, car owners have found out what color car do birds poop on most. Red is the winner, followed by blue. And the research found that birds are less likely to poop on green cars.

  • Red cars – super attractive to birds since red represents ripened fruits.
  • Blue cars – blue reminds birds of the seas. And birds like to poop on watery surfaces.
  • Green cars – birds poop less on green cars, but they do because this color is the same as trees.
  • White cars – polished white vehicles attract birds and scare them, so they poop on cars.
  • Black cars – glossy black car finish reflects bird images, and they poop when faced with their reflection.
  • Silver cars – this color scares the birds, and they poop when they’re afraid.

7 Reasons Why Avians Leave Bird Droppings on Cars


Always wondering why birds keep pooping on my car? As mentioned, car color has a major influence on this act. And aside from that, there are also other reasons why avians leave droppings on vehicles.

1. Reflection

It’s a fact that birds poop on certain color cars, but they do so because of the shiny polish. Avians are known to attack their own reflection, especially during the breeding season. And so when birds see their image on well-polished vehicles, they poop on them.

2. Plumage


Birds are attracted to car colors that resemble their plumage. For example, meadowlarks may prefer to perch on yellow cars because they have similar shades. And they stay on the vehicle long enough to feel nature calling.

3. Watery surface

Fact is, avians poop on water or in the sea. This is because watery surfaces disguise the smell of the bird droppings, which in turn diverts predators. And so when birds see blue cars, they poop, thinking that they’re dropping their waste on blue seawater.

4. Tree parking

Reddit photos of cars parked under trees are beautiful to look at. But in reality, the bird poop on those cars is a serious nightmare. Birds perch on trees, so it follows that they poop while roosting there. And if you park your vehicle to gain shade from the tree, then bird droppings will surely be on your vehicle.

5. Under wire parking

Aside from their natural habitat, birds also love to perch on cable wires. So even if there are no trees and there are still bird droppings on your vehicle, it’s a good bet that you parked under an electrical cable. It’s quite normal for avians to poop while roosting on wires.

6. Marking territory

Dropping waste is a way for birds to mark their territory. So if your car has been parked in the same spot for a few days, then avians may claim it as their own. They poop so other birds will not come and roost with them on your vehicle.

7. Stressed or scared

Birds poop on clean cars because they see a reflection, and they get stressed. Feeling scared or totally excited can make the avians poop. Seeing a car may scare them for fear of getting hurt, especially when the car is about to park where the birds are.

Spiritual Representation of Bird Poop on Cars

More than an annoying occurrence, bird pooping on your car has a superstitious meaning. Avian dropping is a sign of good luck for the car owner. And the more birds leave waste on your vehicle, the more luck you will get. Indeed, bird poop symbolizes prosperity, especially if there’s too many droppings on your car.

But more than superstition, bird droppings on cars have a spiritual meaning. This means that you are urged to slow down. You may have taken the fast lane in life, and it’s time to re-evaluate your choices and lifestyle.

When you see bird poop on your vehicle, you are encouraged to reflect on your life. This is especially true if your car receives poop from the crane bird species.

However, bird poop on cars only has true meaning if humans do not influence the birds to do so. This means that you should not intentionally chase after bird poop.
