If you live in eastern North America, you might be lucky enough to have seen a gorgeous bird called the northern cardinal. The male is especially distinctive, with his breathtaking red plumage and black “mask” on his face.

Up here in Canada, the cardinal is at the northernmost part of its range. We’re especially fortunate that, unlike many songbirds, cardinals don’t migrate south for the winter. We get to enjoy their presence year-round.

But what on earth do the cardinals eat here, when parts of Canada might be covered in several feet of snow?
