I am truly not trying to be rude, but I do feel that I would be completely remise for not saying anything.
This is the 23 thread of this type that you have made in the past nine months. As a minor, I think that it is great that you are taking the initiative to do research, but also feel that you need to try to be a bit selective, if that makes sense. You are ranging from raptors, to rare song birds, to raties, to corvids, to hornbills, etc. Perhaps decide on one type of bird that you are truly interested in and then research it to the utmost of your ability. Then, come and ask some directed questions. As so many species/genuses that you are asking about are rare in captivity, doing it that way will allow for a greater likelihood of you receiving a response to your questions.
With all of that being said, with regards to ratites, such as rheas and emu, please be extremely careful. Not only are you quite young, but also, and I am not trying to be offensive, inexperienced. These species are quite strong and powerful animals and there are many well documented cases of people receiving serious bodily injury from them, especially during the hormonally charged breeding season.
