Years ago, talked with a DNR historian-type guy about "possession," and daily limits. For some reason, I figured that "possession" meant ON you, or in your boat or car. Guess I thought it meant if you were out hunting for a week-end, you could have twice the daily limit with you.
He explained to me it meant, ALL birds you have...on you, in boat, car....and freezer at home.
See, I thought: for instance, if I was having a good season with pheasants, and didn't want to eat two a day, and put some in the basement freezer for winter food, I'd be in accordance with the law as long as I didn't have more than (at the time) 4 birds total with me.
NOPE. Four total, everydamnwhere.
When the regs refer to "bag" limit, I'm presuming they mean you can have:
Duck bag for all seasons: Daily bag of six ducks total which may include no more than:
four mallards of which only 1 may be a hen
three wood ducks
one black duck
but I didn't see "possession" limit.
I have heard of guys freezing ducks to take up to deer camp, and getting ticketed for having more than the possession limit, even though, the birds had been legally shot and then frozen for future use.
Since then, I've always operated as if twice the daily limit was the total you could have anywhere.
Since DNR is one of the few law-enforcement agencies which does not require probable cause to enter your dwelling, I know there were times when I was in violation of the law...with pheasants, at least.
