I was thinking about getting one of these, because I have a giant 4 1/2-5 foot tall bird cage sitting in storage. How much would I have to hold him? Would he have to get used to me before I held him? Are they social? What kind of food do they eat? What temperatures do they like? What's their temperament? What kinds of sicknesses are they susceptible to? How often would I have to take it into the vet for check-ups? Do they like flying a lot? How big of a cage do they need?
