Parrots are perhaps even more attuned to slight inflections in the human voice than dogs are, and they also react to people's body language. A dirty look or stern word from across the room can effectively chastise a parrot and make it stop an unwanted behavior. Most parrots bond closely to their favorite person and seek social approval and rewards, such as being petted. But they will also be very quick to notice and take advantage if the owner appears hesitant or fearful of the bird. Contributing to many behavior problems in birds is the stress of being ignored and alone.
Some people get a bird as an ornament.
Parrots are extremely social animals. It is inhumane to put a bird in a cage and give it no social contact. Most birds get social time with 'the flock' just by being out of the cage and on a perch in the same room with people. Some birds need even more attention. Cockatoos, which like being touched and require interaction all day, are best cared for by people who are retired or who can take the bird to work with them, says Dr. Welle.
