They include stepping up, going to other people, and going out in public. Much has been written about the fact that our parrots are prey animals in the wild. Those in our homes are genetically and biologically identical to their wild counterparts. Therefore, it is in a bird's best interests to teach it to go to and be handled by a variety of people while it is still young. This fact, coupled with our knowledge of their complex personality structure, helps to give us some understanding of the potential need to tailor our approach to teaching the individual psittacine.
Parrots have very different personality characteristics and different approaches to life.
I am fortunate to share my home with two Pionus, a Double Yellow-head Amazon, Blue and Gold Macaw, Goffin's Cockatoo, and four African Greys. The longer I have them, the greater grows my understanding of their differences, as well as the fact that I achieve the best results with them if I tailor my approach to them in consideration of these very differences. They are each a unique personality with very definite preferences. Further some species generalities exist which become apparent from the observation of breeding pairs. I have the opportunity at times to visit a friend's aviary.
