The bisexual cardinal bears a half male and a half body

Because the process of combining the eggs and sperm of the parents is faulty, these individual cardinals are bisexual and possess an unusual coat.

The host cardinal is known to distinguish between males and females by the characteristic color of white and red feathers. But perhaps due to some carelessness of the natural selection process, science has recorded a few bisexual cases of this bisexual species.

The bisexual cardinals individuals carry on themselves two different colors, divided along their bodies. Half of this body, they will have the shape of the female. Meanwhile, the other half will be the shape of the male.

According to the scientists' assumption, the bisexual phenomenon in this bird is due to an error in the process of combining eggs and sperm. If an egg carries the ZW chromosome in combination with a ZZ chromosome, this individual will carry both sets of chromosomes.
