RE: duck slam???
The King Eider is a game bird so it is shootable, as for the swan my book had it in the goose section but it could be seperate for the slam, Michigan does not have a season for them right now but some areas do have huntible populations, and they are talking about opening a season. I would have to travel for a number of these ducks and some of the geese also, but the slams are not suppost to be easy.
