I took a closer look at my photos of the TUNDRA SWANs (Riverlands Migratory Bird Sanctuary -- St. Charles County -- 12/10/05) and realized that, in my confusion, I had taken pictures of two separate adults (plus the one juvenile) for a total of 3 Tundra Swans.

One adult had yellow lores consisting of short, narrow yellow lines in front of the eyes.  The effect was the same on both sides of its head.  This bird also showed a rusty wash on the forehead.  

The second adult had an all black -- or nearly so -- bill with no apparent rusty wash on the head.

At the site I was fairly certain the birds I was looking at were tundras because they were noticeably smaller than the surrounding Trumpeters.
