Only issue I see with that is the potential for cheating.
Jerome, would there be any provisions regarding age of the swans? While from a management perspective, I don't see an issue with harvest of (obvious) juveniles, I do think it would be bad PR.
As for the idea of a waterfowl ID course (outside the swan discussion), I think that is a conversation that should be had on another thread to avoid confusion on this one.
