North America's largest species of waterfowl, the Trumpeter Swan. Some of these photos were taken in extreme conditions. Air temp was -20 and Windchill dropped it to -75. As we say in Minnesota speak, got a little cool that day. Trumpeters are like no other bird in the sky. Grace and elegance on the wing. I remember a flock coursing a river ravine one winter. I will never forget that sight. Their calls rang out as they flew past. It was incredible!
