Cardinals

Other than having an extremely rad name, cardinals can also display bilateral gynandromorphism. According to a study from the Western Illinois University, cardinals not only display gynandromorphism, but they also begin to behave differently. The study (conducted in 2008-2010) show that gynandromorph cardinals did not participate in mating rituals with other specimens from their species. However, they were fully accepted by other cardinals who did not display any gender-nonconforming traits.
