New Book Now Available: 'Acoustic Ecology of European Bats'

A much-anticipated book has recently become available.

Acoustic Ecology of European Bats

Bats, being nocturnal flying mammals, have developed a special and very efficient means of navigating in the dark: the sonar. Although the acoustic signals they emit are inaudible to the human ear, they can be perceived, recorded and analysed with appropriate equipment and software.
This book is a product of the knowledge and skill acquired by its author over more than two decades of constant research on the subject of ultrasound detection. The initial, purely auditory, approach is complemented by the computed-assisted analysis of the ultrasonic signals. With the method described in this book, a bat detector and a computer, the reader will be able to identify about 85% of bat acoustic records in Europe, carry out bat inventories and other more in-depth surveys without disturbing the animals. Thirty-five of the 42 European bat species, including all the most widespread species, are covered.

Michel Barataud has spent many years of research working on the bats of not only Europe, but also the Guianas and Lesser Antilles. Over time, and taking advantage of the ongoing technological progress, he has developed a very efficient identification method and disseminated his findings through a large number of publications. An enthusiastic teacher, he has trained several hundred bat workers in ultrasound analysis and given impetus to a vast network of naturalists.
Yves Tupinier, an expert and pioneer on bat sonar, is a life-long friend. His contribution to this book is a precious addition.

  1. Hi and thanks for the review - book looks really interesting and worth buying as a keen beginner. But I did wonder if this book would be as helpful to someone who only has a heterodyne detector, not a time expansion variety, Sometimes I find that very useful sounding advice isn't useful because it only features one or the other?

  2. Anonymous, it does deal with using a heterodyne detector as well as time expansion, although obviously not in such detail, since there is less detail in the sounds to work with. I like his approach, but have some reservations apart from terminology quirks like referring to the fundamental as the first harmonic! He insists that horseshoe bats use predominantly fourth harmonic rather than second with no justification, he does not understand that hearing is logarithmic and not linear, and so on. So I have some distinct reservations, but still find it a most useful reference taken with appropriate doses of salt.
