What can I say all this advice. I have made sure there is no food for them. The folks next door are OK with it, and I,ve tried plastic owls that worked for a day so that blew that out of the water at 20quid. Meshed off a small bird table, got 2 cats that prefer fish, and I tried cd,s no luck. but I will try the windmill approach why not. If anything its turned into a study of pigeon behavour. If I do take the last resort than. than yes practice first. I have shot before at targets but practice makes the quick kill. I shall let you all know how it goes.
