How do I stop pee wees flying onto my verandah and leaving their droppings everywhere?

The verandah is open on two sides. The birds seem to be spending most of their time by the french doors but I don't see them up that close when I'm at home. The cat and dog walking around doesn't seem to deter them.How do I stop pee wees flying onto my verandah and leaving their droppings everywhere?
this may sound weird but it really works. i have tried it with pigeons that are hard to drive away and they no longer come


Take a piece of black thin cloth about two yards light enough to flutter in the wind . hang it the balcony . it may look ugly but should work. better than cleaning up birds droppings everyday.How do I stop pee wees flying onto my verandah and leaving their droppings everywhere?
They like to look at themselves in the window, I had the same problem. I have put rubber snakes at the window, and on our outdoor setting, I got mine at KMart for $2.00, you can also try an owl statue, this works well also.My parents stuck pictures of a black cat on the window and this also worked.Good luck, we no longer have this pee wee problem!
Go with Daz's owl,we use them on moorings to keep seagulls doing the same thing,available at marine shops in QLD don't know where else.
