Trumpeter swans and tundra swans are two species of swans that are native to North America. Trumpeter swans are the largest swans in North America, with a wingspan of up to 8 feet. Tundra swans are smaller, with a wingspan of up to 6 feet. Both species of swans are white with black feet and bills. Trumpeter swans have a distinctive call that sounds like a trumpet, while tundra swans have a more high-pitched call. The call of a lone Trumpeter swan may be heard regularly from long distances.
Trumpeter swans are found in Alaska, Canada, and the northern United States. Tundra swans are found in the Arctic tundra of North America and Eurasia. Both species of swans migrate south for the winter, with trumpeter swans wintering in the southern United States and tundra swans wintering in the southern United States and Mexico. It can be beneficial for bird watchers to be aware of the distinction between these species and where and during what time of the year they can be observed.
