Deako,
Thank you for your reply, I really appreciate it, I have tried several approaches:
Writing letters to farm owners, by using Yell.com (this did not receive any replies, from 50 letters).
Visiting Farmers (mixed responses ranging from: they already have someone, no I can't shoot and **** off.
I have seen several fields with pigeons on but I have no idea who owns them so I am going to try leaving a water proof letter at the gate.
Do you have any other suggestions?
