On a recent visit to Bowling Green Marsh in Devon, my friend and I noticed what appeared to be a small bird flying low over the water being closely pursued by a magpie. On closer inspection, this turned out to be a bat.This occurred at approximately 4pm when it was still daylight, although the weather was overcast . The bat escaped and, soon after, was seen hunting in the same vicinity, still over water. I haven't a great deal of knowledge about bats, although we do have a couple that visit the garden during the summer months. usually at dusk. I understand there is a daubentons bat that hunts over water. Could this have been what we saw? It seems quite late in the season for this to be still hunting i.e. early November! Over to you experts out there!
