White-edged bat - Pipistrellus kuhlii
The white-edged bat
The sonogram of the call of the white-edged bat.
The sonogram of the white-edged bat falls within the frequency range of 40-45 kHz, which overlaps with other species of the genus Pipistrellus. This overlap makes it difficult to clearly distinguish the species based on the call frequencies alone, as several species call in similar frequency ranges.

Results
Pipistrellus kuhlii was detected in all habitats surveyed, and always with the most call records. In the settlement area of Campese, it was observed hunting at street lamps.
In addition to the white-edged bat, other calls were detected that can be assigned to the Pipistrellus call group. However, these calls could not be clearly identified to species level, as there is an overlap in call frequencies between the species. Due to the accumulation of calls with maximum frequencies above 50 kHz, the presence of the pipistrelle bat(Pipistrellus pipistrellus) can also be assumed. However, further investigations are required for a reliable determination. The presence of P. kuhlii on Giglio is already known.
