These incredible birds are the largest swans in the world. The swans that we usually see on the lakes in Ontario, are mute swans that were brought over from Europe when the trumpeter swans went extinct. Harry Lumsden, a retired biologist from the Ministry of Natural Resources, made it his life mission to revive the species and now there are close to two thousand trumpeter swans in Ontario and forty thousand in the world. Harry, who is now 96 years old, sat down with film producer Michelle Melles to tell his story.
