  I find your comment rather interesting, because it is rather clear that there are no clear divergences in physical characteristics presented in those pictures that would support your assertion. You are quite literally falling prey to confirmation bias. It’s is essentially impossible to tell that there is any difference with that bird if you look at the image in grey scale. The far more likely explanation is precisely that the process that produces the molecule that makes you perceive the feathers are red was disrupted through mutation or other deformity, or maybe even in a similar condition as vitiligo. Just alone the complexity of something like bifurcated sex in a bird makes it extremely unlikely that that is actually what is going on here. You are far more likely also suffering from the mania of the day regarding sex and gender, which had you rationalizing all things in those terms. Remember Occam’s Razor.
