Budgies are sexually dimorphic in only one way: the cere. The ceres of young budgies under 8-12 months are all about the same: a bright pink or violet color. As the budgie sexually matures, the cere (the area above the beak)changes according to the budgie's sex.

++ Females - White/light-blue, tan, or brown cere. This is true for all varieties. With the development of brown color is a flaky texture. This can build up to be about a centimeter thick.
++ Males -
- Blue or purplish-blue cere in normal varieties only.
- Bright violet or pink (does not change after youth)


hope this helps!
