Hi Doc,
Bit last resort I know, but surely you could try finding birds like this yourself?
The problem with giving instructions on a national website is that you don't know who you are dealing with necessarily, plenty of people on here are less than the ideal birder; well honed in fieldcraft, ethical and willing to obey instructions.
Look, I posted some vague directions on here to the birds before it became clear they were lingering, but in hindsight I think that was a mistake. It just seems that with the advent of affordable and easy to use DSLR's, all and any photogenic bird species that get reported to a wider audience get disturbed, or habitat around them gets damaged. For proper rarities that have no real conservation significance, or birds that are passing through and are unlikely to stay for a long period, I would hate to see any news being suppressed. On the other hand, potentially overwintering birds of quite a high conservation significance, I feel should not be widely publicised. The york email group that they were being reported on previously seemed to be an appropriate platform, where most people are known to someone else.
The fact that, despite it being a very good year for SEO's, very few are being reported, seems to suggest that a lot of the people out looking for them would perhaps agree with this point of view.
