BRITISH BAT CALLS A Guide to Species Identification

BRITISH BAT CALLS  A Guide to Species Identification

by Jon Russ

Knowledge of bat echolocation, calls and identification using bat detectors and programs such as BatSound has grown significantly in the last decade. This practical guide presents the latest data in a clear and concise manner.

Part 1 covers topics such as the properties of sound; how bats use sound; bat detection methods; recording devices; analysis software; recording techniques and call analysis.

Part 2 comprises the species chapters. For each species, 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).
