The Cardinal: A Southerner Moves North

Holiday cards often feature gorgeous red cardinals against a snowy landscape. So it’s easy to assume the birds have always been a colorful presence in bleak Northern winters.

But cardinals used to be Southern birds. In fact, they were rarely seen north of Pennsylvania. By the second half of the 20th century, though, they were being spotted year round throughout New York. And they were nesting as far north as Maine, the northern Midwest, and even southern Canada.

There are three key reasons for the cardinal’s northern march. Rising temperatures have reduced snowfall, so cardinals can continue to forage for food on the ground during winter months. Then there’s human development: cardinals are drawn to suburban habitat, so as people convert forests and prairies to cul-de-sacs, the birds soon follow. And finally, backyard bird feeders. By supplying bird seed, we humans help cardinals survive the harsh winters of higher latitudes.

By the 1980s, as if to fully cement the bird’s new turf, its official name was changed from just “Cardinal” to “Northern Cardinal.”

But the southeastern states — topped by Louisiana — still have the most cardinals per acre. The Redbird — as Southerners call it — will always be a Southerner.
