A lot of them do. I am a mod on a bird forum and frankly the amount of people who get mad at their birds for just being birds is pretty high. The playful antics and beautiful feathering makes people fall for them, so they get a bird. Then the bird starts screaming due to boredom from lack of toys, attention and space so they cover it to shut it up, which after years of being cage bound and covered leads to plucking… which leads to the poor babies thrown out with bare chests and self-mutilation habits. There are constantly ads for large parrots around me on craigslist and they are all bald from plucking, with the note “I don’t have time for the bird, need to find it a new home”. The warmer states have issues with people releasing parrots into the wild. So I always put cautions with these types of videos – birds just like bunnies are not for everyone and the large ones are only for rare people who basically want a feathered child, they are way too smart (if you want to see how smart, look up Alex the African Grey) for most people to be able to handle them.
But, they are beautiful and funny to watch.
My mother has a CAG (she found it in the wild in Florida and original owners were not able to be found, think he might have been released, he has cage bound habits) and he is a riot. He torments the poor dogs calling them by name and making kissing noises, so they run around looking for the human calling them. And when my brother entered the house one time the bird yelled “GET OUT!” lol
