Pigeon pie for breakfast! 

I could supply them with unlimited Pigeons.
Two weeks ago I took down my TV aerial from the Gable end wall of my house ( Part of our Patio is below and two of the kitchen windows ) and put on the aerial about 50 stiff long plastic cable ties, some standing up , some to the side, some down, and put up the aerial again.
In two weeks I have not seen a flying
cow Pigeon with bad diarrhoea on the aerial

.
I have seen some pigeons coming to land on the aerial but change there minds and go some other place.
Now I have cleaned the mess off the Patio it's still clean

(still got to get it of the windows, walls etc.).
