From late September until a few days ago, they flew further and further afield from the lake, even as hundreds of other traveling Trumpeter swans and tens of thousands of visiting, migrating birds, visited the lake briefly.
Last week, isolated and shallow portions of the lake started icing over.
Early this week - Monday night - most of the rest or the lake froze, as the temperature dipped to 8 degrees F. We were sure the swan family was gone, but yesterday afternoon, Judy saw them, at the end of the lake where Cottonwood Creek comes in. It is still ice free, but getting smaller by the hour.
Early this afternoon, they walked from the ice free place near the creek, over to another, very small open hole in the ice, where some warm springs come upwelling out of the bottom muck. Little freshwater clams and other food abounds there.
Then, a couple of hours later, they all walked the 120 yards back to the bigger pool.
Should I be worried about these swans?
