Sue, I do understand that you are a birdwatcher and you appreciate watching birds for sport. You need to be appreciative of conservationists (hunters) whom control the population of species of waterfowl. I would like to educate you on a few aspecs of waterfowling.
1) every hunter pays for a state and federal waterfowl stamp in order to legally hunt. This money goes back into the state and nations funds to restore or improve waterfowl habit it.
2) hunters have a certain harvest limit for certain species. The more abundant species we have a higher bag limit for.
3) Ross' geese, and snow geese are a nuisances due to them destroying the tundra (canada) in there breeding grounds due to the overpopulation.
Sue I don't have any intentions of bashing you, all I ask is please look at the big picture with all contributing factors. Hunters not only enjoy the "sport" but also the table fare. Are you telling me that you are a vegatarian? Otherwise the food you eat are commingle from slaughter houses. Everyone has a hobby. Some bird watch, some golf, some do drugs, some drink beer, and some enjoy spending time in natures beauty and enjoying nature while providing food for their families.
