Knowledge of bat echolocation, calls and identification using bat detectors and programs such as BatSound has grown significantly in the last decade. In this practical guide Jon Russ and contributors (Kate Barlow, Philip Briggs & Sandie Sowler) present the latest data in a clear and concise manner.
The book covers topics such as the properties of sound; how bats use sound; bat detection methods; recording devices; analysis software; recording techniques and call analysis. For each species found in the British Isles, information is given on distribution; emergence times; flight and foraging behaviour; habitat; and echolocation including parameters for common measurements. Calls are described in the context of the different technologies used (heterodyne, frequency division and time expansion). Various spectrograms are displayed for each species using examples from both BatSound and AnaLook. An echolocation key is included with the book.
About the author
Jon Russ first became interested in bats in 1994 while completing undergraduate research into pipistrelle social calls as part of an honours degree in Zoology at the University of Aberdeen. This led to a PhD at Queen's University Belfast investigating the community composition, habitat associations and echolocation calls of Northern Ireland's bats. Since then he has been involved in a wide variety of bat-related projects which have taken him from the freezing mists of north-east Scotland and the fine soft nights of Ireland to the humid rainforests of Madagascar, Thailand and Burma.
Jon 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 he continues to be fascinated by these remarkable mammals.
The book includes contributions from Kate Barlow, Philip Briggs & Sandie Sowler.
