商品簡介
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.
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.
