    Can't be 100% certain without catching it I'm sure.

    I must say, at this point in my life I would not find that too surprising -- but I really would like more investigation to take place. It seems to me that there may be more than one explanation for what was observed. I'm more open-minded than many (sometimes to the point of obsenity!) but I really do like more in-depth research for things that I'm being asked to accept as fact.

    Yes, unless one catches a bird and takes it apart it is pretty hard to tell. But there are many other examples of chimera. There have even been people that were chimeras, but I think that they have always been of the same sex. I could be wrong on that last one.

    EDIT: This article only mentions one specific human chimera, she is all female, but that does not mean that some others might not be.

    Technically there are no human hermaphrodites. That's a specific term for organisms which can produce both sperm and eggs.

    Humans born ambiguous, both or neither genitalia, or genitalia that doesn't match their chromosomes are called Intersex.

    I love cardinals. They were some of the few birds I saw out and about during the recent cold snap.

    It's not common but it does happen.

    "Gynandromorphs are found in many species of birds, insects and crustaceans such as crabs and lobsters. This bird is likely the result of an unusual event when two sperm fertilize an egg that has two nuclei instead of one. The egg can then develop male sex chromosomes on one side and female sex chromosomes on the other, ultimately leading to a bird with a testis and other male characteristics on one half of its body and an ovary and other female qualities on the other half."

    Amazing story and reminds us of the plasticity of genetic expression. Oh and when I went to the link it recommended a video at the bottom of the drumming palm cockatoo of Australia. Absolutely beautiful how it modifies a stick to be used for drumming on the trees.

    Weren't sure that it could happen or that this particular bird represents the phenomena? The process is rare but does occur. Seems rather heartless to catch and dissect the bird to find out if this one has the "proof" inside. Oh but some people on this forum are always needing the "proof"; that is except in what they believe.

    Here is an article with more detailed explanation of the process but in a chicken.
