Not really, although it is wonderful to see a flock of so many. Red-breasted Mergansers are a diving duck found readily on our shores. They are funny to watch as they seem to get into spats and chase each other around. I read that a group can sometimes appear to be cooperatively hunting. They will line up and drive schools of small fish into shallow water and scoop the fish up without having to dive, which seems precisely what they were doing when I took these photos.
Feeding amongst the mergansers, a pair of Horned Grebes, a Common Loon, and a Common Goldeneye can all be seen, although both these “commoners” don’t seem at all common to me.

The ducks were fairly far offshore, so please forgive the heavily cropped images; posted only for identification purposes.
