Have you have parrot type birds before? He should make a great little pet provided you give him plenty attention every day and don't just leave him my himself most of the time. Even cockatiels need that though many are just left alone a lot and seem ok but are not in any way tame. Birds are all very social creatures and parrots of all types are much smarter than your average, say, chicken (LOL). They need interaction or they'll start having behavior problems. Or maybe you know that already, if so, I apologize.
In short, bet he'll make a great pet! He's the perfect age to start with.
