I made an illustration (well several in one) for my current favorite prestige drama, @jilldrawblog's MGS fic House On Fire. Go read it! It's about Kaz's divorce from the point of view of his wife :)
It is the Trumpeter Swan - the largest and possibly the rarest swan in north America.
Hunted to the very brink of extinction by 1900; slowly, this bird is experiencing a renaissance. They can be seen in the Midwest again, though they are certainly still a rare sight.
This bird is also the longest-lived and heaviest swan native to north American.
Let's hope that one day, they will be as common and the Canada Goose.
