In some countries it is for example common to shoot european starlings. These birds are not very shy and in continental Europe they live in trees. This will represent a small killzone, not far away and at extreme high angles. As long as field target is derived from a hunting simulation this seems legit.
I agree that Ebern last year was way too extreme but that's the way to shoot in the mountains. On the other hand I'm also hesitant to give a small finch target a 40 mm hitzone and place it on the ground.
