[QUOTE="Richard Klim, post: 1664931, member: 773"] Probably not at this stage. The following paper suggested that the western North American form first diverged from eastern North American and Eurasian forms: [INDENT]Drovetski [I]et al[/I] 2004. Complex biogeographic history of a Holarctic passerine. [url]http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1691619/pdf/15129966.pdf[/url][/INDENT] The proposal to AOU is based upon a subsequent paper, which suggests that this divergence has resulted in separate species: [INDENT]Toews & Irwin 2008. Cryptic speciation in a Holarctic passerine revealed by genetic and bioacoustic analyses. [url]http://www3.interscience.wiley.com/journal/120090385/abstract[/url][/INDENT] But see Drovetski [I]et al[/I] for details of later divergences (which could yet be considered as potential species). [And this earlier BF thread for further discussion: [url]http://www.birdforum.net/showthread.php?t=114503[/url]] Richard [/QUOTE]
