Return Of The Poopy Birds

Yes, it's that time of year again.

We've so far tried putting plastic tarps down along the edge of the pool, where the birds have been dropping their loads. It does some good, as the poop is easier to clean up off plastic than when it's on concrete, but it doesn't really seem to be deterring them at all. I'm thinking that next year I should invest in some barbed wire and see if that works! I really can't figure out why our pool deck is so inviting to the dirty birds whereas the neighbours right beside us and the idiots behind us - both of whom have pools - don't seem to suffer the same fate. Must be my bad karma.
