On our way out of Carlos Avery (a state wildlife sanctuary about a half hour north of Minneapolis) we saw a pair of Trumpeter Swans. These large guys dwarfed the Canada goose that was swimming nearby. One was banded (Z85) around the neck. They spent most of the time with their heads under water. They’re stained slightly pink on their heads and bellies — I suppose due to iron or some other mineral in the water.
