I think thatās an hour long or so show and itās worth watching the whole thing. Itās called Parrot Confidential. The segment you saw, the people had an Amazon parrot and a friend kept it while they were on vacation, the bird bonded with the friendās bird, and the bird did yell no, no, no when the people took their parrot back.
The point of the movie is to show the harm caused to parrots. They interview a couple, who were parrot breeders, and kept getting calls from the people they sold birds to, wanting to know if they would take the birds back. The breeders eventually realize how unsuited parrots are to be pets, stop breeding them for sale, and instead convert their operation to a rescue/sanctuary. They find an old chicken farm and convert it over for parrots.
Thereās lots of footage from around the world, and itās very sympathetic to the plight of companion parrots. I think it should be required watching for anyone thinking of getting a parrot. Yes, it has some difficult parts to watch, but thatās the point.
