During peak time, we're always on the lookout for migrating ducks. In Upper Pool , three species is a crowd!
I passed by Upper pool miafternoon. My target was the Ring-necked Ducks. I found 7 of them. They mingled among the Canada geese. Then there was a Drake bufflehead, I assumed the same bird all winter. To add the third species, Northern Shovelers found their niche here, four birds all together. That's a alot for smallish Upper Pool.
Later I read the hen Common Merganser stuck around on Prospect Lake. It's a pretty good day duckwise for Prospect.Park.
