Too much blueberries?

[Reni]

Mango's diet exists out of Tropican pellets, veggies, blueberries, apples, bananas, cherries, and some cockatiel seed. She loves blueberries and therefore gets about 8 of them in the morning, and throughout the day, my husband will give her one here and there.
My question: can a GCC have too many blueberries or fruit in general?
Thanks.

As with anything, if you overeat one particular food the positives easily turn into negatives. There is also the aspect of your bird probably eating an unbalanced diet as he will fill on blueberries and thus not be eating something else that is necessary,
