Since then his art has raised more than $1 million for Ducks Unlimited Canada (DUC). As Ferris continued to donate his art, he was recognized as tbe Ducks Unlimited Artist of the Year in 1984. “Ducks Unlimited Canada and the work they do is just something that I firmly believed in,” Ferris said from his home in Prince George. "As an artist you get some recognition and it’s wonderful, a feather in the cap. But that’s not why I did it. It did it because I support wetland conservation and I believe in the work.” Throughout almost 40 years donating to the cause, Ferris won the Wildlife Habitat Conservation Stamp competition in 1993 and 2000 and DUC’s Waterfowl Stamp and Print Artist in 2020. He was also one of 30 world-acclaimed artists whose work was included in Waterfowl of North America, a limited-edition book featuring full-size art prints commissioned to celebrate the 50th anniversary of DUC.
