I was talking to a buddy of mine in New Foundland a few weeks back about this. He was saying most Newfoundlanders prefer Mergansers because of their fishy taste.

I have had it before. I have no idea how the guy prepared it, but it was delicious.

I use them for dog training. If you can get your dog to do a blind retrieve on a merganser, and the dog comes back with the bird, your force fetch is done.
