Yeah, I'm pretty sure those are Print tipplers you have. Which is a kind of English tippler.
They both can fly 18+ hours. I am not positive on all the differences but what I understand is Paki's do not kit up as tipplers do. Also high flyers will stay high a lot longer, though tipplers can go high also.
I have talked to many Pakistani fellows who live over in England and know both birds very well. They assured me mine are Print's not Paki's, though some look almost identical. I know they can both come in blue bars.
Google image 'Print Tipplers' and Pakistani high flyer and you will start to see the difference. Paki's usually have a solid neck and head.
I was wrong for months and now finally know...
If you really want to be confused search Danish high flyers =]
(I hear they don't fly long)
It doesn't really matter in the end. You are better off weith the tipplers as far as I see.
They have been breed better.
They all came from the same bird anyways, and I don't mean how all came from the Rock Pigeon.
I believe these English tips came directly from Pakistan, and I'm told Pakistani high flyers originated in India.
