RE: Specific Dog for the purpose
My wife and I hunt only wild birds -- have never tried a preserve. We hunt mostly on foot (or in blinds for waterfowl), but we do some "Jeep Trail" (logging road) hunting with the dog running out in front quartering through the forest for grouse and rabbits.
I like a multi-purpose dog, because wehunt Grouse, Doves, Quail, Pheasants, Rabbits, Ducks and Geese.
I like a dog that can sit quietly in the duckblind in the morning and make ice water retrieves and blind retrieves, and then go out in the afternoon for upland birds. For those (and other) reasons, my dog of choice is the Pointing Labrador.
