I've just received this book, and leafing through it, it looks like a really nice elaborate book. The diagrams in the back are great, with even volume symbols for song loudness.
One thing, for me as Dutchie, which comes across as weird is that The Netherlands is not included as "Western Europe"; maps give only species range for France, Belgium, Switzerland and Britain. That Germany is not included as being Western Europe is...well, quite acceptable, but leaving Dutchieland out but Belgium in points toward the Francophilic nature of the original book, and the Anglophilic of the English translation. How great would a merge be between this book and CD, with the broader species range of the Bellmann! For now I'll have to splurge on buying them both...
Happy with this book, and especially the 222 songs on the CD is something I'm looking forward to, peculiar interest.
