The Bird should be introduced to new people outside his comfort and familiar zone. This way the bird will learn to interact with other people also apart from those whom he knows. Proper confidence should be given to the bird about this and the master/owner should be nearby the bird whenever he is introduced to a new person. The bird should be encouraged to interact with newcomers/strangers. However, proper time must be given to the bird to get him familiar with the new person and it should not be done hastily
