The bird was confused and ran into you or it was on a a suicide mission.
Not all naturally occurring phenomenon are a"sign", more often than not it is just the normal interaction of nature's creatures with us and our "things".
Most likely the bird was as stated above confused or startled, it may have thought the glass was not there due to its reflective qualities or it just may have been unlucky. Birds are really not mentally evolved enough to be despondent enough to try to do away with themselves. That said, however, if the type of bird is of personal significance to you personally, then you may take it as a sign to "watch where you are going"; "pay attention" or that there may be danger in your future.
nothing, that the bird died?
It means the bird wasn't paying attention.
it dies usually.....
the bird needed a big one
There is no philosophy behind a bird pooping on a vehicle. So the only thing it can mean is that the owner may want to wash the window.
just move the bird off to the side of the road and leave. Unless you tried really hard to hit it, it's not your fault and this stuff happens...
When a bird flies at you and hits you it typically means they were unable to see you. It is also possible that they were protecting their young or they have some sort of illness.
Please what's the answer
The windshield is made out of a stronger, more dense material than the bird.
Nothing at all or anything you want it to.
Uh.....NO?!? It just means that they are DEAD not you.
it is seeing itself and thinks it is another bird it poops allover your car while it is doing this.
