As far as what I can say about mine, I was looking for a Maxi, I found one in a bird shop in Chicago. I don't really think she was treated that well, she was supposed to have gotten a few vaccines but I never heard back from the guy that sold her. She's very scared of hands to this day, and I've never handled her roughly, so I think she might have had past bad experiences with getting grabbed. So I kinda can't recommend anyone. My best advice is to find local bird people who might have advice, and check adoption sites regularly. It took me about 6 months of looking to find one that was available anywhere near me.
They're a really rare bird in the pet trade, even though I find them extremely lovable. They're more "dull" looking than a lot of parrots, they have a more calm and subdued behavior, which means they're not as easily seen as silly and fun, and they're sensitive to dust and mold, which makes them harder to keep healthy. This doesn't mean you shouldn't keep looking, but just understand that they're not always easy to find. If you want a bird whose behavior you can predict more, lots of birds out there need a home and you then will know right out of the gate what their behavior is like and how quiet or loud they are.
i want to buy them all!
