By chance, the footage had been saved by a former CBC employee, who donated the film cans to the archives.
That made it easy for CBC archivist Colin Preston to dig them up when the CBC was asked to search for them.
“I just had to trot downstairs, pull the can out, look on the screen and there was the loon,” said Preston, who subsequently unearthed the beaver footage from the archives..
The search continues for the moose and gannet, along with the original French-language set.
Speaking of Beavers, be sure to watch the Nature of Things episode on Beavers as well.
