Macaws are fabulous! Great talkers, loooooveeeee affection and very easy to train due to food motivation. Of course, you will meet some birds who are one-person only (seemingly aggressive), or sex aggressive, but each bird is different and it is really due to how they are socialized, raised, and treated. I have found that the bigger the macaw the more affectionate, and same with noise level. Then again the noise amount has to do with how they're raised, although you can expect when they vocalize that it is too be louder as they are bigger (not to say more frequently- my RFM and B&G are NOT yellers, although my RFM did try the yelling stage around 2.3 years for a few months, but was trained not to). I do not find them to be very complex or hard to handle. My first bird was a RFM and fairly easy. I think people say they are for more experienced owners because the problems are bigger or more obvious- simply because they are bigger. It means more patience. A bigger bird means louder noises, bigger messes, stronger beaks, and stronger rough housing. Compared to a cockatiel they seem harder work, but its just the same work, same routine, but just from a bigger bird.
