I watched this beauty fly down from a tree and land in the snow. It stared at me as I stared at it from my car window. It then flew up to this sign and perched until I drove away.

part of group of approx. 500

Through the scope these were clearly loons but this was the best the camera could do at such a distance.

2nd photo shows most of the group that was airborne and on lake at this location & time
