Female zons are easier than males. Having said that, my first rescue was a redlored female and she was the meanest thing -LOL- She would actually hang from the very edge of the door of her cage, which she would swing open, and stretching her entire body bite you as you walked by. And she screamed all day long. But she calmed down and became friendly and quiet with a good light schedule, diet, freedom from a cage and affection. I had her for 24 years until I had to put her down due to bone cancer...
You mention a dove, an amazon, a gray and a pionus... you do realize that with the exception of he pionus and the zon which are similar in temperament, the others are completely different from each other and what one could give you, the others would not, right?
