Re: Augury, I feel like there’s two ways for this to close though. One is, like you said, trucking the birds from their climate-change-induced altered ranges back to their historical ranges. But, it seems much easier to alter the records of the birds’ historical ranges, a la “the birds have always been migrating over Eastasia.”
So, generally, this ROW concept needs to take account that often this sort of evidence relies on comparing two unlike phenomena, e.g. physically observed bird migrations, with historical records of bird migrations. For the ROW concept to work in practice you need to take account of the ROW on both sides of the “equation.”
