Birds that suddenly start to vocalize less may be stressed, unhappy, bored, or ill. While screaming can indicate underlying stress or unhappiness in birds, so can decreased vocalization. Thus, any bird that suddenly starts screaming should be checked out by a veterinarian to ensure there is no medical basis for this behavior.

Just as biting can be indicative of pain or discomfort, so can screaming. However, a sudden increase in screaming and screeching may indicate that a bird is stressed, unhappy, or bored.

Normal parrots, depending on their species, make loud noise. Since biting also may be a sign of pain or discomfort in birds, a parrot that suddenly starts biting a lot should have a complete veterinary examination to ensure there is no underlying medical problem for this new behavior. Birds will frequently bite and lunge to try to protect themselves when they are afraid. While many bird owners misinterpret birds’ biting as an act of aggression, this behavior is often a sign of stress and fear. How can a bird owner tell that his or her bird is stressed or unhappy? Here are some common signs of stress and unhappiness in pet parrots:

Birds can express unhappiness and stress in several different ways. Birds can certainly feel these emotions and hide them until these feelings become so extreme that they are manifested either physically or behaviorally. While it is often difficult for bird owners to tell whether their pet is sick, as birds commonly hide signs of illness, it is even harder for most bird owners to tell if their pets are unhappy or stressed.
