I can't help but agree with
@JLcribber in someways..
Cockatoos are HARD. Even if RB2s are supposedly the easiest toos, they are still very difficult. Mine is a baby and is still very difficult. I have a good bird experience and him, as a juvenile is already very difficult.
RB2s are my favorite species, I understand wanting your favorite bird/the species that appeals to you. I was dead set on finding a rehome RB2 last year. Nothing could have changed my mind for finding one. I found him and I don't regret him- but he is a HUGE step from my other birds. A step that a lot of people probably wouldn't have recommended, but I took it anyway as a leap of faith. I have yet to even see what he will be like for the rest of his, and most of my life. I could and might regret this in a few years, and I fear for that a lot, but he is with me for life no matter what comes. I made that promise for him. He is mine forever, barring death, basically. Can you promise your bird that?
I do think people can pull off a cockatoo for their first bird.. but that is a very big thing, and you need a lot to do that. Please research more about cockatoos in general. Read the 'bad' and really think about if you can do it... Plucking. screaming, aggression. Illness- RB2s are very very prone to fatty liver disease and obesity. This can dramatically cut their lives in half. You have to be VERY careful about their diets. No seed at all ( expect possibly for treats) . Limit fats. Fresh food and pellets.
I wish you the best with whatever bird you choose! But I can't help but think you might want to aim for a smaller bird first. On another topic I saw you mention conures. They are wonderful birds with personalities the size of a macaw, just not as difficult
Or if you can't do that, are there any rescues you can volunteer at? You said none that were local, but my rescue is a hour and and a half away. It is worth it. I have learned so much there. Experiences I wouldn't trade for the world
RB2s are everywhere in Australia... You won't miss out on your RB2 buddy by waiting until you are ready. No one is trying to be mean, I can see how this might seem very overwhelming, but this is a big thing to do. A VERY big thing. And sometimes we get so preoccupied with what we want we put blinders up over everything else.
