On the Potomac this afternoon, just up river from Great Falls, and at the
upper end of Conn island, were 44 Tundra swans. They were all grouped
together, facing the same direction as if they were getting ready to fly. It
was a beautiful sight for sure. We waited until almost 6:00, but they were
still on the river.  Also a lot of Ring-necked ducks, a few Common
Mergansers, some Bufflehead, 6-8 wood Ducks  along the Md. shore, and also 5
Green-Wing Teal, the males in fine breeding plumage.
