My budgie is at least a year or 2 and when I first got him I concluded he was male as I’ve had some experience determining gender before but as he grew older he has never gotten the signature dark blue cere color of an adult male. I’m fairly positive he isn’t female since his Ceres purple and doesn’t have distinct white rings around his nostrils but I could be wrong...any suggestions?
I don't know a lot about budgie mutations, but could your budgie be a recessive pied?
Male recessive pied budgies have pink/purple ceres when they are adults. This might explain why his cere is not blue despite he is an adult (he is definitely not a female).
I could be wrong, but I am sure that other users who have more experience than me will give you the right answer.
Your budgie looks to be a single factor dominant pied. Depending on if the pied markings affect the cere, males either have a mottled pink and blue cere, which may look purplish like yours or they will get the typical deep blue cere.
