I was driving down the road yesterday morning when I saw a lone mallard drake by the side of the road quacking to something either in the ditch or the woods.
I stopped to photograph him and heard more ducks in the woods. There were two more mallards up there, running parallel to the road, quacking to Mallard in the road. They all became more agitated because I stopped but they did not stop.
Finally, the two in the woods came down the small hill, crossed the ditch, and all three ran down the road together to their farm.
