But man there are good points on this on both sides. Enforcing people who shoot other species will be next to impossible. The few people that will be caught will be made examples of but the vast majority would get away with it. So if species identification, or even people flat out shooting and not caring if its really a wood duck is an issue, that that could obviously create alot of problems.
I'm not an expert, but I think the difference between other states and us here in MN, is that other states don't have the local populations of ducks that we do in MN. When the teal start migrating through other states, they're aren't near as many species to confuse them with, and they aren't really effecting a "big opener" because the majority of the ducks they will be shooting are still far to the north.
To me it really just boils down to a lack of faith in people being lawful, so I wouldn't really be for it.
Nobody cares about your season totals.
