I write a blog called: The Birdbooker Report. Yesterday I wrote about the NEW Advanced Bird ID Handbook by Nils Van Duivendijk. You can see my write-up here: http://birdbookerreport.blogspot.com...-title_18.html

Bottom line: If you already own the author's Guide book from 2010, you'll still want this book!
