The rehabilitation group near me (I have no idea what they're called, sorry) says they have to spend four hours a day per bird to ensure they have the happiest life, and also to ensure they have the best of training, so they'll return and all that good stuff. Even so, twice they've had birds fly off. They said they managed to track down one and bring it home, but the other one disappeared, and because it had never had parents to imprint on it didn't know how to land properly, hunt, or avoid danger, so there is no hope of the poor thing surviving. They also told me about the time they were exercising one of their red tailed hawks, and a wild red tailed hawk came out of nowhere and mortally wounded the rehabilitated one.
The point of this story is, I would be highly against anyone taking this step if they weren't fully prepared to make major sacrifices for the raptor/s. Most people I know who own parrots spend nowhere near the proper amount of time it takes to own a happy bird. Even little cockatiels need at least an hour a day interaction (failing that, another cockatiel). Domesticated animals were bred to conform (somewhat) to the human animal's way of life. When we take on wild animals, we can't shirk the way we too often do with livestock and pets.
I love raptors, but I know I don't have what it takes to consistently give one what it needs on top of all my other buddies clamoring for my time and attention. If you can honestly say to yourself you are able to be consistent in your care and attention, go for it. But I would say even the faintest doubt is grounds for scrapping the whole idea.
Maybe you could volunteer? I shoot and collect sparrows (an invasive breed) for our nearby raptor facility, and I know there are a couple of licensed people who foster birds for a couple of days when the facility gets too crowded. It's worth looking into.
Oy, didn't mean to sound preachy, sorry if I came off that way.
