Birding Frontiers - References - 21 Mar 2012

I pulled this e-mail from Angus Wilson off of the Birding Frontiers listserve that references a number of articles pulled together by Joe Hobbs.  These references are specific to a number of bird families in regards to ID:

"I don't think it's been mentioned in this thread but JOE HOBBS has prepared some very comprehensive and up-to-date listings of articles on ID and taxonomic issues for various bird groups that are frequently discussed on this forum. These can now be downloaded from several sources including websites for Birdwatch Magazine, Dutch Birding and Martin Garner's 'Birding Frontiers' blog. These nicely produced PDF documents provide a terrific resource, at the very least you will know about the articles you don't have ;))
