Index of Identification-related birds
PLEASE NOTE: The entries on this page are quite varied, and some of them suggest tentative IDs that would be extremely significant, were the ID to be confirmed - but almost all of these types of entries remain speculative, and the vast majority have NOT been submitted as any particular taxon - and probably never will be. The main purpose of these kinds of entries is to provoke discussion about identification/occurrence issues, and perhaps broaden awareness of the potential for certain forms to occur as vagrants. Of course, I'd prefer that I am right on such speculations! - but I am much more interested in discovering the Truth, and if that shows me to have been wrong, so-be-it; I usually learn far more when I'm wrong than when I'm right. Feel free to agree/disagree with these speculations - but please do so in a positive manner that hopefully may further the process - thanks!
