My birdie needs to be on diet

This birdie doesn't always appreciate the livestock that I bring home with me but there wasn't a problem with this little chap. :)
I quite literally bought him this afternoon from a man in a pub. I paid sixty quid for him and the price included a big cage on a stand.
I think I detect some Cream Leg Bar and possibly some Indian Runner in him, what do you think?
The man swore that it was POL. I'm not so sure about that but he's definitely finger tame. :)
Seriously though, he's a Quaker parrot and I did only pay sixty pounds for him and the cage and he's very tame indeed.
