British Bat Calls: A Guide to Species Identification

Description:

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 clearly and concisely. Includes 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 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
