Careful with fake owls and hawks. I have seen an RC "falcon" pull a bird in from a couple of miles away, it rolled in and attacked the RC plane. I threw this post up a little while ago:

Hawks and Falcons are covered by the Migratory Bird Treaty Act, and it is illegal to kill them. You can apply for a depredation permit, but you need to prove that the raptors are causing significant financial loss to you. Your best bet is to enclose them in a pen. If that is not possible, there are several suggestions in the post above.
