Why is my budgie's cere changing color? Is it male or female?

Hello and thank you for reaching out to PetCoach! Your budgie who's cere was pink and is now light blue is female. Males usually have a lavender to dark blue cere. We have an excellent webpage devoted to information about budgies; I've put the link below: https://www.petcoach.co/article/budgies-melopsittacus-undulates-species-profile-american-an/ I hope this is helpful! Let us know if you have any other questions!

It looks like Ruby is pretty young, and it is hard to determine sex in young birds. If the cere is turning pink, brown, or crusty, Ruby could actually be a female that is becoming sexually mature. If the cere becomes very deep blue, that is usually the sign of a mature/active male. However- in some color variations cere color doesn't always indicate sex correctly. If the brown is separate from the cere, is discharge, or you're seeing any signs of illness, then this could indicate an issue such as a respiratory infection which should be checked out by your vet.

Budgies are born with blue Ceres. As they age the females Ceres with fade to a yellow brown color. Based on your description, it sounds like Diego may be a female. I recommend using a nesting box that you can pick up from your pet store. It may take some time before Diego gets used to using it.

Thanks for reaching out about Skye. Could be beak and feather mites, that will cause a thickening of the skin. How old is Skye? It is not uncommon for older male parakeets to have testicular tumors that produce estrogen, thereby cere changes color as if a female. A veterinary visit is recommended to help with diagnostics and to discuss possible outcomes. Good luck.

If they are at least 12 months of age, you can determine gender by looking at the color of the cere (nose). In males, the cere is a blue color. In females, it is tan/brown. If they are younger, you will need to wait or you can have them sexed by DNA using blood or feather samples.

Bruno appears to be female. This is determined by the color of her cere ("nose"). In female budgies, it is flesh colored, in males it is noticeably blue. She may be coming into her breeding season which could be a potential cause for the appearance of her cere. She would have to be physically examined by your veterinarian or a vet experienced in treating birds in order to diagnose any infection in the area.

Firstly, are you sure he is male? If he is young and the cere was a lighter color, he may be female and is now coming in to reproductive age which has caused the cere to become darker brown. If he is definitely male, then yes, this change is usually due to a testicular tumor - since the testicles are inside the body you cannot really check this. If you are worried you need to take him to an avian vet and have some blood testing done to check the hormone levels. There is nothing you can do for diagnosis at home. Be sure to take him to a vet that is used to treating birds. I'm glad he is seemingly fine now but that could change quickly as birds often hide how sick they are until they are very sick. Nutrition is important but an all/mostly seed diet usually causes other issues like fatty liver. You need to speak to the vet about how to get him changed over to a pelleted diet like Harrison's. Here is a link to their website. ( https://www.harrisonsbirdfoods.com ) Hope this helps. Best wishes.
