My second ever budgie was only semi tame, named Kitten. She taught herself to explore the whole house. Meaning-in and out of cage, up and down stairs, under/thru open doors. She knew all that stuff. Was wing clipped very very close so she could fly about as well as a pet rock

at the time i was between 10-13 years old so didn't know better.
Yeah budgies are underrated *geniuses*. Can absolutely be trained very well, and can have extensive vocabularies. I had one budgie named Fatty Dingdong who could sure chat up a storm.... All hilarious horrible things for a tiny little boidy to say it was amazing. I miss that bird so much he was such a a character not just the stuff he knew how to say

And all this praise I'm singing for these lil guys?
I've also got a big Mac

and have had other larger parrots in the past, or worked with them.
Budgies and cockatiels are 100% real parrots. And 100% really amazing feather people.
Also I personally am fine with selling my babies to kids, responsible kids. I got my little Tweety bird when I was only 9 years old. Parental supervision can be helpful in learning to care for a pet properly, but I certainly didn't have that! Everybody's gotta start somewhere and youth doesn't necessarily mean they ain't gonna be a great bird caretaker/the best one they can be.
