I'm asking this as a serious question.
Local farmer has hundreds of jackdaws that feed on his farm and in the nearest village and all come to his yard and surrounding trees to congregate, not roost, they fly away each evening. When the young are all out, there really are hundreds. As it's local i go there quite regulary to try to thin them out. I could easily shoot 40 + just sitting on a stool next to a tractor. It's got to a point now though that as soon as i park up in the yard they dissapear.
The farmer says next day when he's there alone they are back.
Is it possible that they recognise me as a threat, and can pick out me from other people ?
