1. I've lived on the gulf coast my whole life.

I’ll never understand why people here have black cars. All white with a light color interior is the way to go.

2. I rented a white car once for two weeks....

I had more birds fly into that car than every other car I've ever owned--COMBINED. I'll never have another one. Birds don't see white. I firmly believe that's why they have problems with wind turbines.

4. The color of the car had nothing to do with it.

As far as turbine blades:
“One possible reason for these collisions is motion smear, which is the visual effect we experience when a fast-moving object appears blurry. It’s the same phenomenon that makes hummingbird wings nearly invisible to us when they’re in flight. We know intuitively that the wings aren’t actually a blur; they’re just moving too quickly for our eyes to process. Some researchers think birds experience the same effect when they see wind-turbine blades, only they don’t have the knowledge to understand it’s a moving object. “
To test the hypothesis they painted one blade black.

Birds can see the color white and will avoid it.
Reflective and metallic surfaces also tend to repel birds. "Large amounts of white, like a white house, might be less appealing to non-white birds (most birds) because their own coloring will contrast starkly, making them more visible to predators," she says.Aug 23, 2019
