It was a treat to see several groups of Trumpeter Swans as we traveled around Wisconsin. They are North America’s largest native bird and the world’s largest waterfowl. The males average wingspan is over 6.5 feet and weigh about 26 pounds. That’s a big bird!
Their call sounds a bit like a Canadian goose with a sore throat.
In the photos you see several swans are wearing collars. They are to track individual birds for study programs. The colors in the colors are unique to species, so the yellow collar verifies that these are indeed Trumpeters.
