Hello Nature Boy,
Welcome. Sounds like you should have a good knowledge base about animals.
Bringing a bird into your life, family, home is a HUGE commitment. It is a commitment for life with this companion bird that will require as much of your attention as though you just adopted a 3 to 5 year old child that will never grow up and rely on you to care for him/her in exactly the same manner for, literally, the rest of YOUR life. If you bring home a youngster that would live upwards of 60 years, then itis a lifetime for you -- the joys will be endless, but the work could be tireless. These birdies are babies their whole lives and we must commit to be 100% responsible to keep them entertained, happy and healthy for OUR entire lives. They should never be thought of as "I'll just sell him if I can't take care of him anymore." or "I'll give her away if I move."
Okay.... so now that I've gone ahead and lectured a little (sorry, I feel it is worthwhile and necessary)... let me say that you should find this site a great place to learn and ask questions before and during your time with a bird. You'll find many people here like me (probably all of them) that are very protective about the companion birds of this world, not just our own.
