Parrots are a sociable species and adapt to the captive environment very well. Thats why we keep them as pets. Thats why they mimic the sounds we make. If a parrot is tamed correctly and given the due respect it deserves then it will never get stressed. Unfortunately many people do not look after them very well and they are often neglected and become frightened. If a bird is just put in a cage and just fed and kept like an ornament in the corner of a room and their owners exihibit erratic noisy behaviour then they become stressed.

I disagree that parrots are easily stressed. Only neglected or wild caught parrots are easily stressed.
