During the period 2001 to 2005 BaTML surveyors monitored the echolocation calls made by Pipistrellus spp. along the canal network that connects the east coast of Scotland with the west coast. During these activities the methods adopted allowed us to simultaneously look at social calls emitted and allocate these to species. When considering these results we found that although the highest emission rate is, as expected, during the month of September, high rates of emission also occur earlier in the bat season.
We have also taken this opportunity to describe the typical social call structure relating to the three species of pipistrelle bat thought to be present within Scotland, namely: Pipistrellus pipistrellus, Pipistrellus pygmaeus and Pipistrellus nathusii.
