Hyderabad is a region in Pakistan: also a region in India. It can refer to Asil that come from either.
In the last year or so, it has become a selling point for some like Rampuri is. Thus, you can't always trust that the birds mentioned are from Pakistan or not. You have to know the breeder.
Of course, in the last year or so I've contacted folks with Asil for sale. They'd say, "These are from doc's (me) birds." I'd say, 'Oh, really.' Then they shoot some fantastic line about how they came by them> ALL A LIE. Amazing.
