They do love to pose and enjoy their bath just about as much, or more, than any other species. They love a good talk while having a bath. I think it's all a part of their fantastic personality.
That other guy has ruined a good bird (Dewars) by teaching it childish nursery rhyme parts. It's quite an old bird now and they never forget what they learn. And in the video he's still encouraging it to say childish things. There seems to be an urge, especially among first time owners, to teach a bird the first thing that comes into their head, which they later regret (when it's all too late). I think it's in order to get to the "eureka moment" as quickly as possible, where they can say to people, "Look. My parrot can talk." This is most obvious with idiots who teach their birds to curse. I don't think there's anything clever about either. But this guy is still bang at it with an old bird. Such a pity, really. There's a lot of more entertaining things you can teach a great species like the yellow nape. And he's a good quality talker, so would have been a start turn if taught more worthwhile things.
Hopefully the Monty Python one's owner can keep teaching him those unique songs and phrases. It's very refreshing to see this in a bird, rather than the silly, common things most people put into them.
Great to see this species generating some more excellent performing examples. They really do take parrots to another level.
