Kenny...sounds like you and I had roughly the same childhood. How nice. Peace, Brother.
I agree with more or less everything others have said here, and like Michael said it all starts with "a fundamental love and admiration" for birds, including, as others have mentioned, an appreciation for birds as creatures with emotions.
Animals aren't just a collection of species, they are nations and cultures and unique individuals...I think people who "get" birds know what that means and regard them with the respect, dignity, curiosity, and care that any intelligent creature deserves. We don't try to bend them to our will without a healthy consideration for their own, and we don't anthropomorphise them or underestimate them. That's where people go wrong with pets, I think, and it's particularly problematic with feathered ones because they just don't play along. Cats are nothing compared to birds in the independent will department, despite their reputation. You really have to earn everything you get with a bird. Not everybody has the patience or even understands the concept of that. I'm glad I do, though. It's been so rewarding.

It was so cool to read so many great responses to this question. Thanks for bringing it up, Kenny. After a couple weeks off this board for the death of a close friend, this was a great discussion to come back to!
