Not sure whether to call it a growl or a purr..it's a vibrating sound? IDK, can't explain it

I did do a quick search about it and from what I read here n there..it's more common with larger parrots, but some budgies do it too.
Can mean happy/content or excited about something OR can be an angry warning.
I guess that's where the reading body language comes in to play again? LOL Grrrrrrrr .... purrrrrr
Hey Andi, at least you can scratch her head! Mine don't like scratches..only occasionally Levi will let me rub his neck a little.
I can pet him with my nose or chin but not with a finger or hand. WT?
