Butt's Up, Doc?

While driving to Anchorage for the dentist follow-up, we passed four ponds and lakes where wild swans live. Conveniently, these were right next to a place beside the highway where we could pull off, and the rain had let up enough that I could take a couple of photos. 
The extras are the swans in a less compromising position. When they tip up their heads are often draped with weeds!
