This timely book is an excellent practical guide to the rapidly developing field of acoustic monitoring and how it can be used to study terrestrial mammals in the wild. The book is packed with useful information and real-world advice. The analyses of example recordings from each species and the accompanying sound reference library are invaluable to anyone embarking on a study of this kind.

– Dr Nigel Reeve, former Head of Ecology for The Royal Parks

Regardless of your level of expertise this book has something to offer, reminding us that sound, which plays such an important role in bird identification, is missing from the mammal toolbox, especially for the ultrasonic noises of the small mammals. Written in plain English so its meaning is clear, and with case studies for hard to record species like dormice, this book will open up vocalisation as a recording method to all mammologists.

– Derek Crawley, Vice Chair of the Mammal Society

An essential aid to identifying those mysterious sounds in the undergrowth. There are bird sound guides aplenty, but mammals have long been poorly represented. This excellent and detailed publication plugs that gap.
