Last winter after seeing how long-winded a Scoter was at S Platte Res (mine was a Surf Scoter), I was also compelled to time it's dives. I was amazed at the consistency, every dive I that timed was one minute, six seconds. After about eight dives, I just walked away shaking my head, wondering how many other interesting things are going on out there that I have yet to notice and figure out.
