Jump shooting is probably where most guys enter water fell. Is Loki doesn't require any special gear except maybe a dog. There are many different styles and strategies for waterfowl hunting. You could sit in a a blind in a field waiting for geese or you could sit in a curtain blind on the East coast waiting for divers to come in 20 feet of water.you have the resources I would tell you to find a guy and get a couple of different hunting experiences like that.if not getting plugged into Delta waterfowl and another local duck hunter will really help you out. Each state probably has its own duck hunting waterfowl group on Facebook, find Montana waterfowlers on there.
As for ID nothing is going to be putting eyes on birds. We will be coming into the spring and there are many places you can find spring plumage birds. Pick up a quick reference waterfowl ID pocket guide and start trying to figure out birds on the water before you do it on the wing.
