I love birds!!!
I use to have some 2 budgies and 2 king quails (both breeding pairs) in a small aviary... After the female died - after a good 6 - 10 years I could handle getting more, so I brought the male inside.
The male was rescued from a person who was going to release it into the wild as he didn't want him anymore... Really sad, as he was kept in a small cage - no flying room and wasn't tame, so didn't fly for a good 5+ years - when was placed in my aviary, wow, should've seen his birdy face! Took him a while to learn how to fly, but i think he loved it!
Anyway, when I took the male inside i got some java finches and worked with taming my male! he was semi tame probably due to me giving him what he wanted - freedom, plus good food and water! So he did have regular outing of his cage when he was in my home - which he loves, as my home was bigger than my cage! But he died after living with me for 7 years - I think - before he died - probably due to old age as he was fine the night before, but in the morning, he was gone...
6 months later, I decided to get rid of my aviary due to me not finding the time that the javas and quails deserved..
But recently, I been bitten by the bird bug and becoming really interested in breeding show type budgies... Sigh, it like fish tanks, once bitten, you can never get rid of it!
