Stopped by South Platte Reservoir today at around 230 this afternoon, and found 4 Red Breasted Mergansers, 1 female, 3 males. I parked at the second parking lot and walked up to the top and turned left, as this is the only side with much open water. The reservoir is mostly frozen, but the water on this side was open, and the ducks were on the far left where there is open water, close range. Not many ducks out, should be easy to see, scope is great, but not absolutely necessary. Life birds for me!
