Tonight I took my Bat detector and powerful torch to work in the hope of seeing a Daubenton's bat. The River Lee runs along the back of my workplace and I have seen one a few years ago along this stretch. Just after 10pm myself an a work colleague, Stuart, headed off to the river whilst on patrol. Stuart had not seen a Daubenton's before and it was not a long wait to see one either, within minutes we were watching a "water bat". The brown colouring contrasting with the creamy white underside as it flew back and forth skimming the water like a nocturnal sand martin. We located another further along, this one flying around willow trees on the waters edge and over our heads. A great experience that definitely out done my last sighting.
