Budgerigar is an Aussie word that means "mighty fine eating". Budgie is just shortened. I have had them off and on since 1976. I now have an adorable pair - The Honeymooners Alice and Ralph.
Best one I ever had was Adam Smith. I spent a lot of time training him. He could say > 200 words or phrases.
When a woman walked in the door he said 'Hiya Chick" while giving the shweet-shwew (how spell that?) whistle.
When someone started to leave he said: "Close the door, thank you"
I would say Adam - introduce yourself and he said: "I am Adam, who are you? Who are you? Who are you?"
And lots of other stuff - all recognizable.
He loved to perch on my right eyeglass wing.
He was a real hoot.
One of my other favorites was Willie Nelson.
