As I mentioned in my post to your “Migration routes” thread, time would be required to mingle the infected populations
It seems like the amount of time necessary would be on the order of years. I.e., several migration cycles to allow the intermingling needed.
It would seem that poultry smuggling could be more at fault. Poultry or pet birds?
