Air Rifle Hunting Wood Pigeon Decoying And Boy Its Hot

I was asked by a farmer friend to help with a problem he has with birds attacking his fields of barley as it was still not ready to harvest, the most of the birds were rooks and jackdaws which i never managed to get a shot at but i did manage to bag a few wood pigeons which will go into some game pies.
This is all done on farm land that i have permission to do so on with legally held air rifles and is done in a legal and humane manner as not to prolong or glorify the death of the birds.
This can legally be done through the Department Of Agriculture, Environment And Rural Affairs Wildlife (Northern Ireland) Order 1985 (As Amended) Licence.
