These Photos Show a Rare Half-Male, Half-Female Cardinal
Bird watcher Shirley Caldwell was looking out at the bird feeders in her backyard when the Erie, Pennsylvania, resident spotted an unusual bird: it was a half-male, half-female cardinal.
National Geographic writes that the bird’s anomaly is known as a bilateral gynandromorph, in which half of a creature’s body is male and the other half is female. Gynandromorphs are likely found in all species of birds, but they’re much easier to spot in species where the males and females have distinctly different appearances (something known as sexual dimorphism).
Here’s Nat Geo’s biological explanation of how these “male/female chimeras” come to be:
Here’s a short video Caldwell captured of the same bird:
In 2018, a photographer in Alabama captured a “one-in-a-million” photo of a yellow cardinal.
