There's always a few around the tree tops outside here edge of the woods and all, last night well before 9 and still light although overcast there were more than usual some small and others notably larger. Not sure what pipistrelle and ? ian
Here in east London I have been sitting out as it is getting dark for a few nights (glass of Sauvignon Blanc or Shepherd Neame 1698, in hand ) and the numbers of, I assume, pipistrelles have been quite low compared to other years.
A couple of nights ago I counted only five bats in about an hour.
We see very few bats where we now live but had pipistrelles roosting in our roof at our previous home. Don't know if this is going to work - a short movie clip of the bats at dawn with the dawn chorus audible in the background.
