Signs of life

Busy evening with yoga followed by book group. I hadn't read the book but enjoyed the discussion anyway and had a good catch up with the group.  We were able to sit outside for our meeting.  Used the new bat detector on the way home and it does seem to have picked up a few calls from pipistrelles. I need to go down to the river to test it properly.  
This is one of the calls as shown on the detector app.
