For each species in the British Isles, information is given on distribution, emergence times, flight and foraging behaviour, habitat, echolocation calls and social calls.<p/><br></br><p><b> Book Synopsis </b></p></br></br><p>Knowledge of bat echolocation and social calls, and identification using ultrasonic 'bat detectors' and sound analysis software, has grown significantly in the last decade. In this practical guide Jon Russ and contributors (Kate Barlow, Philip Briggs & Sandie Sowler) present the latest information in a clear and concise manner.</p><p><br></p><p>The book covers topics including the properties of sound, how bats use sound, bat detectors and recording devices, analysis software, and call analysis. For each species found in the British Isles, information is given on distribution, emergence times, flight and foraging behaviour, habitat, echolocation calls including parameters for common measurements, and social calls. Calls are described in the context of the different technologies employed to record them (heterodyne, frequency division and time expansion). Various sonograms for each species are displayed in BatSound and AnaLookW. A species echolocation guide is included.</p><p/><br></br><p><b> Review Quotes </b></p></br></br><br><p>Armed with this practical little book, researchers, surveyors and amateurs can go out into the night with the benefit of the knowledge and experience built up over the years by Russ and his colleagues.</p><p>-Andrew Branson, British Wildlife</p><p>A long-awaited book on bat calls has been published by Pelagic Publishing. Written by Jon Russ, it gives a very clear explanation on how echolocation and bat detectors works. There are colour illustrations of sonograms for each species of British Bat and also includes a very useful selection on bat social calls. It covers heterodyne, time expansion and frequency division. It is well set out and great for quick reference.</p><p>-Bedfordshire Bat Group</p><p>It's safe to say, that I own many books on the subject of Bats. ... I can state here and now, (with certainty) that this book surpasses the others on its overall (up-to-date) content, and execution. In conclusion, the book is very well laid-out. It's very informative, and a fantastic reference, to re-visit again and again! ...Now if only a bat expert from the US (of Jon Russ' caliber) would publish a book similar to it (for North American species)...And soon! I'd be very happy!</p><p>-Al Milano, Bat Detector Reviews</p><p><br></p><br><p/><br></br><p><b> About the Author </b></p></br></br>Jon Russ is the Director of Ridgeway Ecology, a specialist bat consultancy, and has worked for a number of years for the Bat Conservation Trust coordinating the iBats project in the UK and Eastern Europe. After nearly twenty years involvement in bat research and conservation around the world, he continues to be fascinated by these remarkable mammals.
