when i wanted to move my birds from my mums to my own house, i thought that i would have problems,but within 6 weeks my neighbour that had very serious doughts about pigeons had changed his mind, on asking why he said that he could not belive that someone could have so much control over his birds, and that was 3 years ago and he would still say the same today .[cant beat the good old whistle it works wonders] just shows you if you try things can turn in your favour
