This absolutely is a true problem that I have and desperately need
help.
I park my car off-street (no garage) as parking is very limited
in our area. SInce spring began, the local birds have been using my
side view mirrors as toilets.
Each day when I go to work, I find that about half of each door
beneath the mirror is absolutely caked in white bird poop (stands out
very much on my navy-blue car).
I mean it's absolutely caked on! As if two dozen birds had
moved their bowels in that same spot! The birds actually sit on the
mirror, and poop onto the cardoor. The rest of the car is untouched.
Today I actually caught one bird sitting on the side-mirror
taking a dump onto the car!
I know this is funny, but going to the car-wash before work
every morning (sometimes twice a day) is becoming expensive not to
mention time-consuming.
I've parked the car here for years and never had this problem
until this year. Any idea what is up and how to keep the birds away???

It's the mirrors. Try putting a baggie on them to see what the birds
doo or do not doo.
