Hello John, first of all, nice gallery! But, do you know the latin name of the Tundra Swan? Because here in Europe, the Tundra Swans have more yellow on their bill. Here in Belgium it is the Cygnus colombianus bewickii, a rare winter bird.
John, this is a splendid gallery of the Tundra Swan. The first shot of them in a heated discussion is superb!! I look forward to seeing more of them in the future. Cheers, Judy
