My favorite trick for taming is to put some meal worms in a bowl, then have bird to be tamed placed on lap next to bowl. Bird will have to be restrained gently. Let eat a few, then release her. Little later repeat process. Be carefull not to stress bird when collecting it. Do not look directly at it either, maybe percieved as threat. Always move with a slow deliberate manner. Then put plate with mealworms at your feet. Stay seated do something like reading. Want bird to approach you. Then get bird to jump to you lap. May take baby steps (short jumps). Looking for bird to get onto lap for feeding and eventually sit on your lap. This process needs to be carried out over several days. Criterion for tame with my trainees is bird will crouch with wings allowed to fall open and preening while in contact with me. Willingness to fall asleep also a good sign. Really tame birds will approach and jump onto lap without food as inticement.
