How do birds accurately predict the path of vehicles?

260 viewsBiologyOther

I see crows and magpies on the road all the time. Vehicles coming at them at 60km/h in a curve. The bird can skip 10cm in one direction to avoid the trajectory of the vehicle. How do they manage that? You rarely see avian roadkill.

With most cars, the aerodynamics will cause the bird to miss the car even if the bird does a poor job of getting out of the way. The bird is riding air currents and those are going over or around the car.

If you ever own a car with a vertical windshield and poor aerodynamics, you will quickly realize birds are not as good as avoiding cars as it seems. A mini van I owned ages ago was like that and over the years I had several birds slam into the windshield.
