Emphasize your tone so that the bird picks it up more quickly. Training lessons should be short at about 10 minutes to avoid stressing the bird. It is always easier to start off with a young bird. You can discipline your pet just like any other intelligent pet. Please refrain from physical abuse as this provokes the bird to become aggressive.
Greys are devoted to each other and preen each other just like the lovebird species of parrots do.
If you keep a lone Grey, it will devote itself to you. The bird will clamor for your attention and relish hopping all over you. A neglected Grey may scream and call to you. If you are leaving the room for a length of time, it is better to calm the bird by using a cage cover. The Grey has a tendency for feather plucking and mutilation.
