I was momentarily distracted by the Canada Goose With A Treasure while watching the two Hooded Merganser drakes show off. When I reverted my attention to the ducks I saw that a few more females and another male had joined the party.
The three drakes performed tight circle maneuvers…
… that ended with a spirited chase.
The females lost interest and pretty soon they all casually swam to the other side of the pond, out of my view.
