Here's another late reply, confirming the previous one basically

I had a female Alex for a year, raised her from 3 months old. She was sweet, gentle and generally quiet. Alexes are gentler and quiter than IRNs. Her only noisy period was for two weeks while she was weaning as she used to scream a lot before, during and after feeding but as she grew up she stopped on her own.
I can say she was one of the smartest parrots I trained, smarter than some CAGs I trained and way more responsive. She was a talker too and they have their own lovely voices. Super independent, I wouldnt worry about her handling any situation she faces on her own. She didn't over bond and she treated the household as her flock. She used to get very enthusiastic everytime one of us returned home and greeted us

Big big chewer and used to go through a new toy almost every week.
I highly recommend Alexes if you are NOT into cuddling and expect to spend lots of time outside the house.
