Message: <blockquote data-quote="Richard Klim" data-source="post: 2837513" data-attributes="member: 773">British recordsSorry, John, can't help with the individual records.  But if BOURC adopts Svensson's recommended split, it'll certainly be interesting to see how it plays out wrt existing British records. BOURC and BBRC currently accept 41 records of albistriata (up to 2011), with all other records of Subalpine Warbler either attributed to nominate cantillans or racially unidentified.  But the racial attribution seems to have been rather informal in comparison to the level of proof normally required for the acceptance of records of a rare species...Hudson et al 2012 (Report on rare birds in GB in 2011):How many of the 41 probable/possible records of 'Eastern Subalpine Warbler' are likely to be considered fully acceptable species-level records after a split?</blockquote>
