We were told Sola our budgie was a male. She has the traditional yellow/green/black budgie. She came with a much lighter bluish/pink tint Ceres and now is currently pink. Our blue guy is about five months old and his ceres is blue.
Your budge looks female. Budgies go from pale to darker depending on whether the conditions are right and if they are hormonal. They are mature at about 8-9 months, pretty fast for the parrot world. There are some that change but it's usually female to male (pink-blue and it isn't too common the other way), specific genetic and nutritional factors aside.
Sexing Parakeets (Budgerigars or Budgies).
This one goes on to add some additional visual differences.
Below you can see Remi a male who is about 3 months old, his is blue Sola is about 8 months old and her dares is white/blue but we believe it will become a darker white or brown as she gets older.
