Overhead Danger, Missoula, Montana

On the subject of overhead birds, this I wonder: How can three days of intermittent rain not be enough to wash the bird splotch off my driver’s side car window?
It’s a recurring terror: each time I shoulder check, there’s a heart-stopping nano-second when said splotch masquerades as a white car in my blind spot.
 
Of course, the moment of alarm passes, and I forget about this little problem - until the next driving jaunt.
If I were smart, or was in a moment of focus beyond that of a gnat, I‘d water up a paper towel right now & take care of this business.
 
But where’s the fun in that?
