It seemed to me at the 00:47 mark, the bird called its owner a...um...bad word. (but it could just be my human side reacting to the owner saying “I beg your pardon?” after the bird said it!)
It didn’t seem like it was conversing, as much as it was saying whatever it wanted, and its owner was just adjusting her side of the conversation.
Still pretty impressive vocabulary and vocalizations, though.
A few years back, I sat next to the woman who owned the famous African Grey parrot “Alex” who was the subject of her research for thirty years and wrote a book “Alex and Me” about it.
I asked her what it was like, and she said sometimes, it was like having a petulant, willful, adolescent!
I once knew a guy who made good money selling talking parakeets. He had a number of birds, but his myna was a prolific talker (he also imitated the phone and doorbell which could be annoying). Anyay this guy bought regular non-talking parakeets for ten bucks each (a long time ago) and put them in the room with the myna. Within a month they were all talking, imitating the myna. Then he would sell them for $25 each.
Cute!
