Abstract

A method was developed for individual and roost identification using the echolocation calls of wild big brown bats, eptesicus fuscus under natural conditions. The recordings were done with multi-array condenser microphones and Avisoft Recorder USG. The system allows the recording of a wide range of acoustic frequencies and can provide images of inaudible sounds in waveform, spectrogram and energy displays. The capacity to recognize roost mates play a significant role during foraging and hibernation.
