    Cere colour change in adult male budgies may be cancer

    I just wanted to tell you all something interesting that I just learned. Apparently, an adult male budgie whose cere turns from blue to brown could have testicular cancer.

    This makes sense, because the testis produces testosterone, and without testosterone, feminization can occur, in humans, anyway. Before anyone gets too nervous about your little babies, remember that this is in adult birds, not babies whose ceres are still changing colour. I read somewhere else that tumours do not usually appear in budgies under three yers of age. I am not sure what the age statistics are for testicular cancer.

    Re: wowzers!

    Wow! I made it into the faq! To think that after all this typing and blabbing, I made it into the FAQ! So now that I am in the FAQ, I feel the need to provide a bit more info.

    I found mention of another cause of a male's blue cere colour changing to brown, besides a tumour of the testis. Apparently, this can also occur when a submissive male budgie is housed with other males - his cere may turn brown to show the others that he is not a threat. Here is the link, and you have to scroll all the way to the bottom of the page to find the section that deals with the topic.

    I also read in one location that hormonal changes are common in budgies. I can't remember where I read it - it was just that one sentence - not very useful, but if you are ever faced with this problem, ask your vet.

    Re: cere changes

    Hi.

    The same thing happened to my male budgie of a few years ago.

    The reverse can also happen with female budgies, their cere can turn from blue to brown, which can suggest ovarian cancer. This happened to my bird recently, but it turned out to be something temporary caused by the hormone injections she was being given as part of a treatment for egg binding.

    I have had lond discussions about this with my Avian vet. He says that a cere change can also mean that a bird had both male and female parts. Some birds who are hermaphrodites can also have ceres that are coloured blue and brown.

    A brown cere on either a male or female bird should be checked. If it is thick and crusty it can be excess keratin which can be picked off. I think that is possibly called hypertrophy (am not suer), and is caused by obesity and fatty liver. I am not entirely sure how this affects ther cere, but I guess it is hormone related which may produce the excess keratin. When I mentioned before that my male birds cere went brown, this was the cause and fortunately not testicular cancer. Sorry I can't be more certain with this account, it was about 5 years ago. I hope that a majority of it is correct.ping

    It could also be a reproductive cancer.

    Usually this occurs after 2 years of age. Blood tests can determine the cause usually. Also note if you have multiple birds, it isn't unheard of for subordanate males to have a tan cere. My budgie died of testicular cancer at 11 yrs of age, and his cere did not change. We found out through a blood test and x-rays.
