https://www.nationalgeographic.com/animals/2019/01/half-male-half-female-cardinal-pennsylvania/JEFFREY AND SHIRLEY Caldwell have been attracting birds for 25 years with carefully tended backyard feeders. But the lifelong Erie, Pennsylvania, residents have never seen a creature so wondrous as the half-vermillion, half-taupe cardinalits colors split right down the middlethat first showed up a few weeks ago in the dawn redwood tree 10 yards from their home.
In fact, they werent sure they saw it correctly until it came in closer. Never did we ever think we would see something like this in all the years we've been feeding, Shirley Caldwell says.
The anomaly is known as a bilateral gynandromorph. In plain language: Half its body is male and the other half is female. This remarkable bird is a genuine male/female chimera, says Daniel Hooper, a postdoctoral fellow at the Cornell Lab of Ornithology, in an email.
Gynandromorphs, known as half-siders among ornithologists, are rare but not altogether uncommon. They likely occur across all species of birds, Hooper says, but were only likely to notice them in species where the adult males and females look distinct from each other, a trait known as sexual dimorphism. Cardinals are one of the most well-known sexually dimorphic birds in North Americatheir bright red plumage in males is iconicso people easily notice when they look different, Hooper says.

Who fucked up ?
Was God to blame ? Will he take full responsibility here ?
Or will God just pass off the fuck up and blame Mother Nature ?
Makes one think,.. Maybe there is a genetic component to human sexuality and it is all beyond the grasp of human preferences and human choice,.. but more likely written deep within our genetic codes. Or maybe it is a Devine Intervention that took a shape detour into the lands of having severely fucked up,.. Like fucking royally !
Don't expect Fascists to begin to comprehend what is at play here,.. they are devoid of the subtleties of societal nuances. Their world's are colored either in the whitest of white or near total darkness of black,... but never do they see, explore, or entertain, the conception of shades of gray - critical and analytical thinking is beyond reach and incomprehensible to them. We suffer that reality,.. they welcome and embrace the Donald J. trDumps of the world.
In spite of it all,.. Humanity Evolves to the next level of a higher civility.

(3,254 posts)I don't know the percentage by gyandromorphic birds were a given among a large population. The birds get sexed after hatching and the Toms and hens are kept seperate because the hens will peck the Toms to death. But their were alwas a few in every pen of about 3000 who were both sexes. With some humans you can't positively say if they are male or female.
