Black Birds bombing my pool?

Question:Why would Black Birds be bombing my pool? Every morning when we go out to check the pool there is a BUNCH of bird crap all over the side of the pool and in the bottom. We saw the birds today fly over and crap on the pool then fly in another direction. They are doing this on purpose! They came straight for the pool, crapped on the way over... sounded like rocks hitting the sides then they swerve so it's obvious this is a plan of theirs. WHY WHY WHY???

Answers:
Oh, dear, I don't think they are doing it on purpose. Your pool is just in their flight path. The black birds and crows are crazy this time of year. They are getting on my nerves, too. Do you have any shiny objects or decorations around the pool that could be attracting them.
