Vespertilionidae
Acoustic Identification bats of Antigua and Barbuda
Family
Scientific name
Eptesicus guadeloupensis Genoways and Baker, 1975
Taxonomy follows Simmons and Cirranello (2022)
Call shape
FM reversed J broadband short duration
Only a few full spectrum wav files are available for this species. Of the 4 contributed WAV files only one had a complete call pulse. Call fragments from the others were used to derive ~ parameter measurements.
The first is the full spectrum file with a single pulse followed by the ZC converted file.
An estimated ZC complete call sequence is also provided.
Vocal signature parameters
A very limited set of measurements exist and are from only 4 call pulses extracted from a single wav file recorded by Barataud (2016).

Known distribution
Although it tentatively appears the calls of this species were recorded by the Dept. of Environment field team on Antigua during a pilot project.
