Es ist gar nicht so leicht, eine Gesamt-Zusammenstellung der Sperlinge (also nicht mehr der gesamten Webervögel) und Finken zu finden. Hier nun eine optimale Zusammenstellung von gelungenem Bild-Material und vertieftem Text - typisch für den "Helm"-Verlag.
I am a breeder and distributor of different finches and this book has been the best resource I have been able to find. The picture plates are finely detailed including many sub-species of each type of finch. It even covers some finches that are too rare to be covered in any other book. There is detailed information on each species including, but not limited to, regional location (including migration and breeding maps), identification, differences between sub-species, availability, habitat requirements, food eaten, and scientific and local names. I really want someone to make a book as well done covering Weavers, Whydas, and Buntings. If you are looking to identify species and sub-species of finches then this is probably the only book you will need--period.
