This Northern Cardinal was caught and banded by IBBA ( Inland Bird Banding Association) members in central Texas!
The bird shows apparent bilateral gynandromorphism, a rare abnormality that causes it to have female plumage on one side of its body and male on the other. Such birds have both an ovary and a testis.
