Hello! thanks for the replies!
My grey's name is Freddie. I have taught him to step up(but sadly only on perches) and he bows his head down for a scratch when he sees my hand. I also have taught him to shake hands/high four
He used to make alot of cute noises like different calls, and things like water drops, but he stopped now

I hope to hear more about your progress with your Pionus.
I have owned 2 cockatiels

but sadly, they both passed away

It is not only fine feathers that make fine birds.
