A National Geographic article is featuring a Pennsylvania couple that spotted a rare bird in their yard: a half-male, half-female cardinal.

The gynandromorphic bird was spotted in Erie near the home of Jeffrey and Shirley Caldwell.

Shirley Caldwell snapped a photo of a rare half-male, half-female cardinal as it say on a tree branch near her home.

Also known as “half-siders” among ornithologists, gynandromorphs likely occur in all species of bird but are only noticeable in species where males and females look distinctively different.

Male cardinals are a bright red shade, while females have a more taupe color.
