Hey guys, I was recently on a backpacking trip to Isle Royale and these little ducks were swimming around in front of our campsite. They appeared to be alone and without a parent duck. The three stuck together and were diving a lot. I dont know much about diving ducks and looking for an ID on these. http://imgur.com/qwFLTTc They were quite small which is why I assumed they are juvenile but I could be wrong. Black bills and redish brown heads.
