Or fed on imported food as suggested? Maybe I'm way off the mark but what imported food would you feed an Eagle Owl on in the UK.... would have thought most would be locally sourced? Or is it usual to import such food? Anyone in the know?Also is it legal to import a captive bird from Europe?.... I'm not sure on the law regarding importing captive bred birds into the UK? (sadly I'm sure the law actually wouldn't have that much bearing on if birds were being brought in anyway)I think the point here is if there is any suggestion wild birds are coming over in a "wild state" this should be taken into account when the idea of culling is put forward as it has been through the application for the license... if there is a chance that these results do indicate birds are coming over from the continent then caution must be used before giving permission to shoot all EO's which could result in a genuine wild birds being killed in the UK?As I have said before I'm not sure where I stand in this debate... but if these results are proved true and accurate I would be swayed into the "leave well alone" camp......ATBSteph'</blockquote>
