My friend inherited an old male budgie when an elderly relative died. he looked so miserable that she bought him a 'lady friend'. He sat hunched up on his perch for the rest of his life, not even looking at her but occasionally giving her a sharp nip if she got anywhere near him. Best way to tame them is to clip a wing so they can't fly away, they go like putty in your hands. Instant taming, I didn't believe it till I saw a friend with a pet shop do it to one that had just been sold and was wild as an eagle. Within seconds it was sitting on her hand as quiet as a lamb.
