Ducks on the pond

I saw four ducks swimming in the pond, on Wednesday morning, and just saw one flying toward the north side of the pond. I cannot catch enough of a clear view to identify them, although they are probably either mergansers, buffleheads,  or ring-necked ducks, as those are usually the first species to populate the pond after ice out. My fractured toes are not ready for long walks yet, but I am hoping to hobble over to the edge of the pond, sometime this weekend, for a closer look at the ducks.
