What the open water yields

A quick look at Prospect Lake after work did yield some noted ducks. First, the HOODED MERGANSER pair was out in the open.Then as I crept closer to shore, the hen COMMON MERGANSER got spooked and flushed, flying into open view,landing in the water.Then last, as I was unable to see with the sun in front of me,  I moved to my right, a pair of WOOD DUCKS waddle on the ice ,then back and forth; it appears some courtship ritual is going on.
