Air Rifle Hunting Wood Pigeon Decoying With A Helpful Buzzard

I was asked by a farmer if i would help protect his barley as it was getting ready to cut and the wood pigeons and crows were starting to attack it, one or two birds is no problem but you can get flocks of hundreds of birds descending on the fields and eating the barley before it can be combined.

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.
