On Wednesday evening I visited the mere with Anthony Nickson from Merseyside Bat Group. As usual there was a lot of bat activity, but it was subtly different to previous nights, with many more Noctules than usual, and a lot less Daubenton's. We had three different types of bat detector with us, a heterodyne, an EM3 and an Anabat.
Using the results from a GPS attached to the Anabat, Anthony was able to create a Google Earth KML file which maps the positions of the bats we recorded around the mere. Because there were so many bats, there is a lot of overlapping and therefore not every record appears on the map at this resolution. We did pick up 6 calls from bats which Kaleidoscope identified as Serotine, and two of these are marked on the maps as "Big bat". However due to the large numbers of bats in a relatively confined area, it seems most likely that these calls were actually Noctules in a clustered environment.
Pipistrelle records. P55 = Soprano Pipistrelle, P45 = Common Pipistrelle
