great suggestions
we got a little lucky in that my husband found a hawk one morning who had hurt its wing. He was able to catch it by throwing a towel over it and then took it to our local wildlife rescue group. It had a broken wing that they were able to set and when it had healed they wanted a "safe" place to release the hawk. of course we offered our barn. we set the hawk loose inside our indoor arena - has a large door that stays open at one end and then open along the top of the east wall. The hawk comes and goes - we don't see him for a week and then he hangs around for a while. We saw a big decrease in the birds. And we noticed a significant decrease in birds in our other barns as well as when he is visiting. fun story with an unintended result. you might talk with a wildlife rescue group in your area as they are often looking to release rehabilitated birds of prey into a safe environment.
Other suggestions -
we have two cats that like to climb the rafters and they get into the nests - that has helped a lot but don't have a clue how you would train a cat to do this :)
Also knock down nests in the spring as soon as they start to build them so that they don't lay eggs.
Have used fly strips but tacked where they like to nest - stay in place well and the birds hate to step on them so they tend to avoid them. i.e. tack along top of rafter. not sticky enough to trap them but just discourage them.

You can buy rifle shells for .22 rifles that are loaded with shot rather than a single projectile. This shot will not penetrate the building or even the insulation. What I have is Winchester NO. 12 shot. It is made for this and similar purposes. We ended up shooting a bunch of them and then the rest just left and none ever came back. I don't like doing it but it was the only way we could find to rid ourselves of them . They will reproduce worse than rabbits if you don't get rid of them.I read your next e-mail about steel spikes to put on cross beams and that would certainly be a preferable method if it works. Good luck, please let us know how you handle the problem.Dave Richie----- Original Message -----From: JaJaxBob@...Sent: Friday, November 03, 2006 1:30 PMSubject: Re: [usdfregion4] pigeonsthanks dave. i have heard that also. the problem is my arena ridge line is 16 feet tall so how would one manage that?
