[Ed. – Yes, literally male-plumed on one side, female on the other, with biology to match. Think I’d stay away from Bodega Bay for a while. And Padre Island, for that matter. Next up: ravens flying upside down.]
A northern cardinal with an extremely rare abnormality was discovered in central Texas.
According to the Inland Bird Banding Association, 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, they said.
