Not really as you have "baited" the birds in. This hardly complies with the requirement of dissuasion. Either you have tried to dissuade them or you have enticed them in, it can't be both.
I have no problem with people shooting birds that are on the Licences as long as the Licences are complied with.
When you deviate from that and it's found out, you are just another hooligan with an airgun, shooting birds. That does none of us any good at all.
