I'm sorry that your question wasn't answered in a timely manner. Can you upload a photo of Bluey's cere to our conversation? You can use the paperclip icon in the toolbar above your message box (not if you're using the chrome browser) or you can use an external app such as or I can be more accurate for you if I can see what you're seeing.
I suspect that his cere has become hyperkeratotic - excess keratin has formed on it. This can be a benign change but also worrisome for testicular cancer if Bluey's previously blue cere has turned brown. His diarrhea could be related to such a cancer but isn't pathognomonic (specifically indicative) of cancer. It's more commonly due to bacterial infection.
I'm pleased to hear that he's eating well and eating such a good variety of human foods. It would be prudent to initiate a broad spectrum antibiotic dosed directly into his beak. This would need to be prescribed by an avian-oriented vet such as could be found here: Please avoid over the counter antibiotics designed to be placed in his water if only because birds don't drink enough to medicate themselves properly.

Hi Arlene,

I'm just following up on our conversation about Bluey. How is everything going?
