Today the sky is nearly empty of trumpeter swans, but once they were more common across North America. Here is a short course on the history of your new species.

Trumpeter swans nested throughout the north-central region of the continental United States, in parts of Canada, and in the southern half of Alaska. It's likely that they once wintered in parts of all the lower 48 states, but by the beginning of the 1900s, they were thought to be near extinction.
