Male cardinals are red, females are white....

Uh, no. Males are red, and
“Females are pale brown overall with warm reddish tinges in the wings, tail, and crest. They have the same black face and red-orange bill.”

Do you have any more science for us?
I was basing my comment on the appearance of the photo rather than from a font of knowledge about bird-watching. I am not a birdwatcher, but there is no doubt that the bird in the photo is a gynandromorph, half-male and half-female. The same can be said of the butterfly I pictured. http://news.discovery.com/animals/bi-color-cardinal-mystery-110531.htm
The birds out in CO must be smoking drugs out there or something along with the dizzy drugged up loons living there.
