: how do you know how many trumpeter swans are on the continent on North America?
Thanks for your question, Chris. The most recent estimate I was able to obtain was that there are approximately 20,000 trumpeter swans in North America. This informtion was taken from the Yellowstone Resource and Issues Handbook, 2003.
