As part of our quest for a Nathusius we have done two daylight reconnoiters of Stewartby lake. The woodland is still in an early stage of development, so we were not over optimistic, but we went back last night, detectors at the ready. What we had failed to appreciate was how bad the light pollution was. We heard common pipistrelles but few sopranos (who seem to prefer good woodland cover), and there were a few noctules over the lake., but the activity rate generally was very low.
Hopefully in years to come, as the woodland develops it will get to be more like the other water bodies we survey at the moment
The bird song at dusk was a delight though
Meanwhile the hunt continue – watch this space.
