A comprehensive guide to the calls of the 44 species of bat
currently known to occur in Europe. Following on from the popular
British Bat Calls by Jon Russ, this new book draws on the expertise
of more than forty specialist authors to substantially update all
sections, further expanding the volume to include sound analysis
and species identification of all European bats. Aimed at
volunteers and professional alike, topics include the basics of
sound, echolocation in bats, an introduction to acoustic
communication, equipment used and call analysis. For each species,
detailed information is given on distribution, emergence, flight
and foraging behaviour, habitat, echolocation calls - including
parameters of common measurements - and social calls. Calls are
described for both heterodyne and time expansion/full spectrum
systems. A simple but complete echolocation guide to all species is
provided for beginners, allowing them to analyse call sequences and
arrive at the most likely species or group. The book also includes
access to a downloadable library of over 450 calls presented as
sonograms in the species sections.
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.
