Dear Sirs, This is perhaps the one automotive question which I can address with any degree of expertise. I am referring to your caller of January 18 who asked about bird excrement on his automobile and whether birds aim for cars of a particular color. While I cannot comment on the psychological aspect of aeriel bird bombardment, I can speak with some degree of knowledge about bird vision.
Bird vision is quite unlike human vision.
However, a white car is certainly a more inviting target than a dark green one, which the birds would likely not see at all, especially against a black background of asphalt. Now, as for hitting it with bird droppings, well, I guess that s up to the individual bird. Here's some of the good stuff that's come in recently.
