Observation details
Two groups of four swimming through a pond. One group took a break on the rocks and cleaned their feathers. The other group was later floating around people on the shore. All this in about an hour and twenty minutes. Unable to distinguish between American Black Duck or Mallard because neither group flew from the pond.
