At last some reasonable weather to undertake the first of three bat surveys on the tunnel to look for roosting bats. We had sufficient volunteers to keep and eye on both ends of the tunnel and also have a look to see what species we could find around the village. Two remote detectors and recorders were also placed inside the tunnel, one at either end to catch any movement from within. We still have to analyse all the sonograms but it was quickly clear that Common pipistrelle was the majority of the bat calls, with possible Noctule and Brown long-eared to be confirmed from near the hotel. The tunnel was quite foggy when we started as the hot air from the sunny day cascaded into the cold tunnel and made quite a draft. This subsided during the evening and was clear by the time we finished recording at 10.00pm.
Pauline had the nice experience of a Tawny owl drifting over and landing in a tree in front of her. Sadly it did not stop long enough for a photograph, quickly detecting that it was not alone.
The next survey date is May 18th.
