Wow, Ben, thanks for sharing that. My transgender response was supposed to be a joke, but I think the joke's on me. That's really an incredible display of genetics and a testament to nature's ability to adapt.

Interesting tidbit: gynandromorphic zebra finches have been used to study the differences in neuronal patterning involved in processing song between males and females (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC153648/)

Transgender. (or, less likely, leucism that just by chance manifests on one side of the bird)

Dipped on Vermilion Flycatcher Saturday at the Thompson's, but did see one weird bird: a Cardinal.
Here's the catch: one side of the Cardinal looked like a male with bright red feathers; the other side looked like a female with brown feathers. Looked like someone had put the bird together from different parts.
Anyone ever hear of a bird like this?
