After driving away all the geese, the Muscovy swam off. At this point I went to check on the little duck. Last I had seen, it had swam under the pier and come up on the land. I was surprised and saddened to see it had pulled itself up a few inches onto dry land, then died. I don't know if it died from being underwater too long, or from exhaustion or its heart simply gave out.
