If the main reason for the September opener is simply to shoot BWT and woodies, I call BS. There are TONS of woodies and teal around in October. I’ve never understood that argument.
100 years of refuge counts, banding data, bag/hunter surveys, and aerial surveys saying BW teal and wood ducks leave MN in significant numbers by early october vs your observation that there is “tons” around.
There’s a reason MN wants that september opener, and that’s to put the most hunters in the field with the best chance at shooting ducks. BW teal are already migrating right now. We can all argue our opinions on whether the splits and current framework is working or not, but you can’t refute the fact that by early october, the state has lost resident birds. The compromise would be allowing a teal season, but MN will never get it as long as hunters annually mistake pelicans and swans for snows, black angus bulls for deer, and cormorants for black ducks.
