CLOSED: Swan ID

I took these photos at Tule Lake National Wildlife Refuge in the Klamath Basin (California), and I think these are Tundra Swans, but I'm not positive. If you click on the areas of the images where the beaks are located, this will bring up a magnified view, showing yellow spots in front of the eyes. I'm sorry for posting links instead of actual photos, but I can't reduce the size of these images at this computer, and the large files won't load.

Thanks in advance for the help!

Yep, Tundra Swan is right
